Emotion-packed design, sporty character and innovative technology: Audi is targeting a new market segment with the A7 Sportback. The large five-door model with the dynamically accentuated rear end brings together the best of three worlds: the sporty elegance of a coupe, the comfort of a sedan and the practicality of a station wagon.

The A7 Sportback is pure high-tech. Its body is very lightweight thanks to numerous aluminum components. The elegant interior shows a craftsman’s level of workmanship. The four V6 engines combine refined power with groundbreaking efficiency. The 3.0 TDI with 150 kW (204 hp) and multitronic has CO2 emissions of just 139 grams per kilometer (223.70 g/mile). The sporty chassis comes with new solutions, such as electromechanical power steering. When it comes to assistance and infotainment systems, the luxury-class coupe exhibits all of the innovative power expected of Audi.

The five-door coupe from Audi combines supreme, long-distance comfort with a sporty character. The interior noise level is very low even at fast highway speeds, with the V6 engines providing refined acoustic feedback as their power unfolds.

The excellent vibrational comfort likewise contributes to the atmosphere of cultured tranquility on board. This is the result of painstakingly tuning all components, systematic hydraulic damping in the axle and drivetrain bearings and the extremely stiff body. The body is comprised primarily of aluminum and high-tech steels, making it extremely lightweight and safe. The large rear hatch opens wide to reveal a large, extremely usable luggage compartment that is very easy to load. Its 535-liter (18.89 cu ft) capacity swells to a volume of 1,390 liters (49.09 cu ft) with the rear seat backrests folded down.

With the A7 Sportback, which will be rolling into dealerships in the fall at a base price of €51,600, Audi is taking up a new design line representing elegance on a grand scale. The five-door coupe is 4.97 meters (16.31 ft) long and 1.91 meters (6.27 ft) wide, but only 1.42 meters (4.66 ft) high. Its long hood, the short front overhang, the long wheelbase, the sportily flowing C-pillars and the sharply dropping rear create a dynamic overall impression. The five-door coupe is an aesthetic athlete with a wide, powerful road stance.

Optional LED headlights reinforce the unmistakable expression of the A7 Sportback and provide all light functions with light-emitting diodes while minimizing energy consumption. Bi-xenon headlights and LED tail lights come standard. The innovative all-weather light function has also been integrated into the headlights, replacing the classic fog lights.

The sinewy sportiness of the exterior carries over into the interior of the A7 Sportback, where Audi again demonstrates its leading role in automotive design. The salient element is the “wrap-around,” a horizontal line that encircles the driver and front-seat passenger in the interior to provide a feeling of safety and security. The wave-shaped application strip with its integrative dynamics is the salient element of the dashboard.

The utmost care has been devoted to every last detail in the interior. Workmanship is at a craftsman’s level. Optional climate-control and massage functions are available for the front seats covered in high-grade Audi leathers. The optional ambient lighting fills the entire interior with atmosphere.

Like Audi’s A8 flagship, the A7 Sportback also combines a new level of technical intelligence with logical, intuitive ergonomics and self-explanatory operation. The advanced MMI operating system with central menu button and reduced number of buttons comes standard, while one of the options is a new head-up display that projects the most important information on the windshield. The MMI touch system combines a hard drive navigation system with the convenience of touchpad input.

The driver can use the touchpad to perform numerous functions, such as using his or her finger to write the letters of the destination or the digits of the telephone number.

The online services work together with Google to connect the five-door Audi coupe to the Internet via the Bluetooth car phone. A UMTS module delivers images and information from Google Earth to the monitor and combines them with the navigation route. A WLAN hotspot is used to connect mobile devices. Further to the Bose sound system, the top-of-the-line option is the Advanced Sound System from Bang & Olufsen featuring 1,300 watts of power and
15 speakers.

The top navigation system works closely together with the many optional driver assistance and safety systems in the A7 Sportback. It forwards the route data to the control units for the headlights, the automatic transmission and the adaptive cruise control with stop & go function, enabling these systems to recognize complex scenarios. In many cases, the Audi pre sense safety system can reduce the severity of accidents and their consequences. The new Audi active lane assist helps the driver to keep the A7 Sportback firmly on course, and the new park assist system relieves the driver of the chore of steering when parallel parking.

Audi will initially offer the A7 Sportback with a choice of four powerful and cultivated V6 engines: two gasoline and two TDI units. Their power output ranges from 150 kW (204 hp) to 220 kW (300 hp), and their efficiency sets impressive new standards in the vehicle class. The new 3.0 TDI with 150 kW (204 hp) and multitronic consumes on average just 5.3 liters of fuel per 100 km
(44.38 US mpg), corresponding to CO2 emissions of just 139 g per km
(223.70 g/mile). All engines use Audi’s innovative thermal management system, a recuperation system and a start-stop system.

The standard automatic transmissions also play a role in the high efficiency of the Audi A7 Sportback. Audi offers two different transmissions depending on the engines: The continuous multitronic sends the power to the front wheels, while the sporty seven-speed S tronic works together with quattro permanent all-wheel drive. The latest evolutionary stage of quattro features a crown-gear center differential and torque vectoring.

The drive system is particularly flexible and dynamic. The optional sport differential actively distributes the power between the rear wheels.

The chassis also combines sporty precision with luxurious comfort. The Audi
A7 Sportback rolls on large wheels measuring from 18 to 20 inches in diameter. The chassis features aluminum control arms and a newly developed power steering system with an electromechanical drive for high efficiency. The Audi drive select dynamics system is standard and can be supplemented by the optional adaptive air suspension with controlled damping.

Audi is adding another model to its R8 high-performance sports car lineup: Hot on the heels of the R8 Spyder 5.2 FSI quattro comes another model with a V8 engine. The 4.2-liter FSI produces 316 kW (430 hp) and launches the open-top two-seater to 100 km/h (62.14 mph) in 4.8 seconds on its way to a top speed of 299 km/h (185.79 mph). The engine is mated to the R tronic sequential manual gearbox; quattro permanent all-wheel drive is standard.

The R8 Spyder 4.2 FSI quattro has a lightweight cloth top with a fully automatic drive. Its body is an aluminum Audi Space Frame with large-area components of carbon fiber composite material. A fit and finish typical of Audi, excellent everyday practicality and optional high-end technologies – from LED headlights to seatbelt microphone – complete the profile of the model athlete.

Superior power: the engine

The free-breathing 4.2 FSI is a high-performance engine such as can be found in racing. It delivers an experience that enthralls all of the senses – with spontaneous, voracious throttle response, with its easy revving, with hefty torque, prodigious power and sonorous, voluminous music.

The V8 accelerates the R8 Spyder from zero to 100 km/h (62.14 mph) in 4.8 seconds and on up to a top speed of 299 km/h (185.79 mph). Both values apply for the manual transmission and for the R tronic. At Audi, dynamics also always means efficiency. The R8 Spyder 4.2 FSI quattro with the R tronic consumes on average 13.9 liters of fuel per 100 km (16.92 US mpg); fuel consumption with the manual transmission is 14.9 liters per 100 km (15.79 US mpg). A recuperation system that recovers energy during braking is standard. The forced oil pump of the dry sump lubrication system features various suction and discharge stages for load-dependent operation.

The 4.2 FSI, which is also used in this form in the R8 Coupé, produces 316 kW (430 hp) from a displacement of 4,163 cc – 73.5 kW (103.2 hp) per liter. At the nominal engine speed of 7,900 rpm, the long-stroke (bore x stroke 84.5 x 92.8 millimeters [3.33 x 3.65 in]) engine's eight pistons travel 24.1 meters (79 ft) each second. The electronic rev limiter kicks in at 8,250 rpm. The V8 delivers 430 Nm (317.15 lb-ft) of torque to the crankshaft between 4,500 and 6,000 rpm, with at least 90 percent of peak torque available between 3,500 and 7,500 rpm.

The compact V8, which is hand-assembled at the engine factory in Györ, Hungary, has the classic cylinder angle of 90 degrees and weighs just 216 kilograms (476 lb). Its crankcase is made of an aluminum-silicon alloy using the low-pressure die casting method, which ensures particular homogeneity. The high silicon content makes the cylinder barrels extremely resistant to wear.

A bedplate structure gives the crankcase its high rigidity and optimal vibration behavior. The cast iron bearing bridges reduce its thermal expansion and thus keep the play at the main bearings of the crankshaft within tight limits. The forged crankshaft, the forged steel connecting rods and the forged aluminum pistons are extremely lightweight, yet strong. The dry sump lubrication system with its separate oil tank enables the engine to be installed very low while also ensuring the supply of oil to the engine even under extreme lateral acceleration.

The high-revving V8 FSI draws its fuel from an FSI gasoline direct injection system – typically Audi. The common rail unit injects the fuel at up to 120 bars of pressure. The fuel mixture is swirled intensely in the combustion chambers and thus cools the walls. This allows a high compression of 12.5:1, for increased performance and efficiency. The 32 valves are actuated via roller cam followers by four camshafts, each of which can be moved through 42 degrees of crankshaft rotation. They and the ancillaries are driven by zero-maintenance chains running on the back side of the engine.

The 4.2 FSI breathes through straight aluminum velocity stacks 23 centimeters (9.06 in) in length integrated into the dual intake system. The intake plenum is made of lightweight plastic. Vacuum-actuated flaps controlled by the engine management system are integrated into the intake ports. They cause the air to move with a roller-like rotation (to "tumble"), which increases the efficiency of the combustion process.

The dual-branch exhaust system features dual tailpipes. The exhaust system components and the pipes of the manifold have been designed for low backpressure and are very light. The exhaust flaps in both tailpipes open at higher load and engine speed for an even fuller sound.

Dynamic: the drivetrain

The Audi R8 Spyder 4.2 FSI quattro comes standard with a manual six-speed transmission. It works together with a compact dual-disc clutch and can be shifted extremely precisely and easily with short throws. The shift lever is made of polished aluminum, the open gate of stainless steel.

The R8 Spyder 4.2 FSI quattro is optionally available with the R tronic, a highly efficient sequential six-speed transmission. Shift commands are transmitted electrically; a hydraulic system changes the gears and manages the clutch. The R tronic offers both an automatic and a manual mode, both of which allow the driver to choose between two shift programs.

In manual mode, the driver changes gears using the joystick on the center tunnel or with the paddles on the steering wheel. At high load and engine speed, gear changes take less than a tenth of a second. The Launch Control program ensures optimal starts. It controls the engine speed and the engagement of the clutch to accelerate the open-top two-seater with the ideal wheel slip.

The quattro permanent all-wheel drive delivers the engine's power to all four wheels. Together with the locking differential on the rear axle, it provides significantly greater traction, stability, cornering speed and precision. The four powered wheels seem to claw into the asphalt at the exit of the corner, and the driver can get back on the throttle sooner than in a car with rear-wheel drive.

Due to the mid-engine layout, the quattro all-wheel drive system in the R8 Spyder is a special design with a strong rear bias. The transmission, which is mounted behind the longitudinally installed V8, has an auxiliary drive for a cardan shaft running past the engine to the front.

A viscous coupling distributes the torque at the front axle. During normal driving, it sends roughly 15 percent of the torque to the front wheels and 85 percent to the rear wheels. If the rear wheels begin to slip, an additional 15 percent is quickly sent to the front. A locking differential at the rear axle further improves dynamics. It provides up to 25 percent lockup when accelerating and up to 45 percent when coasting. If a wheel on one of the axles should slip, it is braked by the EDS electronic locking differential.

Highly emotional: the design

The R8 Spyder 4.2 FSI quattro is 4.43 meters (14.53 ft) long, 1.90 meters (6.23 ft) wide and 1.24 meters (4.07 ft) tall – it has a wide, hunkered-down stance on the road as if ready to pounce. Its dynamic proportions, the sculpted design and the passenger cell situated far to the front with the flat windshield visually underscore the mid-engine concept. The large vertical air intakes are athletically sculpted out of the flanks, and the shadow contour of the rear end forms a powerful wave above the wheels.

An elliptical crease encircles the long back and provides visual structure. When viewed from above, it combines the passenger compartment and the engine into a single unit. Two arched cowls in glistening silver give the back a powerful profile. They taper from the bulkhead to the spoiler lip, and each includes six integrated air vents. Another wide discharge vent is located between the cowls.

Numerous other touches – from the single-frame grille painted in high-gloss black to the exposed gas cap of solid aluminum – document the Audi designers' great attention to detail.

The headlights are technical works of art – this applies to the standard xenon plus units and even more so for the optional LED headlights, which use light-emitting diodes for all lighting functions. Their reflectors resemble open mussel shells, and the daytime running lights appear to be a homogeneous strip extending along the lower edge of the headlight. One of Audi's greatest innovations, the LED light, has a color temperature very similar to that of daylight, making it easier on the eyes when driving at night. It also impresses with a long service life and extremely low energy consumption.

The rear of the R8 Spyder 4.2 FSI quattro features LED tail lights as standard equipment. The exhaust system terminates in dual tailpipes on both the left and the right. The rear spoiler, which extends automatically at 100 km/h (62.14 mph), and the fully lined underbody generate a downforce that presses the high-performance sports car firmly to the road. With a drag coefficient of 0.37 and the small front surface area of 1.99 m2 (21.42 sq ft), however, the two-seater still glides easily through the wind. Audi applied a lot of the knowledge gleaned in motorsport to the flow of air around and through the body.

Audi offers the R8 Spyder 4.2 FSI quattro with a choice of three colors for the top: black, red and brown. The body is available in the solid finishes Ibis White and Brilliant Red; the metallic finishes Suzuka Gray, Teak Brown, Ice Silver, Jet Blue and Aurum Beige; and the pearl effect finishes Daytona Gray, Sepang Blue, Lava Gray and Phantom Black. The windshield frame is coated with anodized aluminum.

Just 215 kilograms (474 lb): the body

Equipped with a manual transmission, the R8 Spyder 4.2 FSI quattro weighs only 1,735 kilograms (3,825 lb) (including driver), and just five kilograms (11 lb) more with the R tronic. The decisive factor for this low weight is the aluminum body, which features an Audi Space Frame (ASF) design.

The body in white consists of three wrought components: Extruded aluminum sections comprise 75 percent; vacuum-cast nodes 8 percent; and the aluminum panels that are integrated into this skeleton with friction connections make up the remaining 17 percent. The body is largely assembled by hand with the utmost precision.

The open superstructure features special reinforcements in the area of the sills, the center tunnel, the rear bulkhead, the floor and both the A and B pillars, yet still only weighs 216 kilograms (476 lb). The high stiffness of the ASF body, which includes a co-supporting engine frame of ultra-lightweight magnesium, provides the foundation for the dynamic handling, superior crash safety and high vibrational comfort of the Audi R8 Spyder. The body tops its segment in terms of lightweight quality – the relationship between weight, size and torsional stiffness.

The side panels of the open-top two-seater are made of ultra-lightweight carbon fiber composite material (CFRP), as is the large cover over the roof compartment. They are produced using a new method called resin transfer molding (RTM). In addition to being faster and more energy-efficient than conventional production in an autoclave, RTM also yields superior surface quality. The use of carbon fiber composite enables weight savings of up to 60 percent over conventional steel components and also permits greater design freedom.

Lightweight and convenient: the cloth roof

The R8 Spyder 4.2 FSI quattro has a cloth roof – a classic feature typical of Audi and without compromise for a high-performance sports car. The soft top's approximate weight is a mere 42 kilograms (93 lb); it thus keeps the vehicle's weight and center of gravity low. The top takes up little space when open, and is a harmonious design element when closed. It tapers off to two long, slim fins that extend to the trailing edge of the car and have an elongated contour similar to the fixed roof of the R8 Coupé.

The outer skin of the top is a leakproof textile fabric. A headliner covers the frame, which is made primarily of die-cast magnesium and aluminum. The soft top is fully suitable for high-speed driving. When driving at moderate speeds with the top up, interior noise levels in the R8 Spyder are barely higher than in the Coupé. The cloth top has an electrohydraulic drive that uses a system of actuators, hinges and hooks to open and close the top within 19 seconds, even while driving at speeds up to 50 km/h (31.07 mph). When opened, the 1.7 square meters (18.30 sq ft) of fabric folds in a Z-shape into its storage compartment over the engine. The CFRP compartment cover moves on two seven-joint hinges. The precise mechanical interaction of the two components is a pleasure to watch.

The heated glass window, which is separate from the cloth top, is lowered into the bulkhead between the passenger compartment and the engine compartment. It can be raised and lowered at the press of a switch, with the soft top up or down. An additional wind deflector comes standard. It latches into the bulkhead behind the seats in two steps and keeps the cabin nearly draft-free at speeds of up to roughly 200 km/h (124.27 mph).

The top with its rear-window module, the storage compartment, the cover and the rollover protection system forms a premounted assembly. It is inserted into the ASF body at the manufacturing plant at Audi's Neckarsulm site, where the R8 Spyder is built, lending the body additional stiffness.

Located in the bulkhead is a rollover protection system comprising two strong, spring-loaded sections that shoot up within 0.2 seconds when needed. In the event of a side impact, head/thorax side airbags in the backrests protect the passengers. Full-size airbags stand at the ready in the event of a head-on collision. In a rear-end collision, the integral Audi head restraint system reduces the risk of whiplash injuries.

Technical expertise: the chassis

Mesmerizing emotions embedded in perfect technical expertise – the R8 Spyder 4.2 FSI quattro is an integrated system of speed. It steers spontaneously, almost reflexively, into corners and takes them with stoic composure. The limit is very high and easily controlled. The hydraulic rack-and-pinion power steering connects the driver intimately with the road. With a steering ratio of 16:1, it is sporty and direct, but never nervous in its response.

The R8 Spyder 4.2 FSI quattro has a wheelbase of 2.65 meters (8.69 ft). Its axle load distribution is 43:57 percent; the track measures 1.64 meters (5.38 ft) up front and 1.60 meters (5.25 ft) at the rear. Forged aluminum double wishbones – a principle borrowed from race car construction – locate the wheels. Their rubber-metal bearings divert the lateral forces precisely into the body while at the same time ensuring high longitudinal elasticity. The setup provides for surprisingly good comfort in everyday driving. A dedicated sports suspension is available as an option.

Another option for the R8 Spyder 4.2 FSI is Audi magnetic ride adaptive damping. The system uses magnetic fields in the hydraulic shock absorbers to adjust their response to road conditions within milliseconds and adapt to the driver's style. There is a choice of two basic characteristics. During fast cornering and when braking, the control unit reduces body pitch and roll through the targeted increase of damping force at the individual wheels.

The R8 Spyder 4.2 FSI quattro rolls on 18-inch wheels shod with 235/40 tires up front and 285/35 tires in the rear. A tire pressure indicator is standard. Audi offers optional 19-inch wheels in a variety of designs – monochrome or two colors, polished or in titanium look.

Behind the wheels are powerful disc brakes measuring 365 millimeters (14.37 in) in diameter up front and 356 millimeters (14.02 in) in the back. To quickly dissipate the heat, they are internally ventilated, perforated and composed of two pieces – stainless steel pins connect the steel friction rings to the aluminum caps.

Black, eight-piston calipers grab the front discs, with four-piston calipers used in the rear. The 19-inch wheels are optionally available with perforated carbon fiber-ceramic discs that are extremely lightweight, robust, long-lived and corrosion-free.

The open high-performance sports car has a specially configured stability system on board. With the touch of a button, the driver can activate a sport mode that permits exciting but safe oversteer when the gas is applied while exiting a corner. The ESP together with the anti-slip control can also be deactivated completely for dynamic driving.

Luxury and dynamics: The interior and equipment

Three strengths characterize the interior of the Audi R8 Spyder 4.2 FSI quattro: the uncompromising quality with respect to the use and finish of the materials; the generous amount of room; and the high degree of practicality.

Drivers and passengers of any size find an ideal seating position in the sport seats with their pronounced side bolsters. The ring of the leather multifunction sport steering wheel is flattened. Visibility is good, with narrow A-pillars ensuring a large diagonal view to the front. Another advantage in everyday driving is the luggage compartment – there is space under the front hatch for 100 liters (3.53 cu ft). A storage box with three bins is located behind the seats.

A large arch, the "monoposto", encircles the interior, which is distinctly oriented toward the driver. The controls are clearly and logically structured; the standard automatic air conditioning system is specially matched to the needs of open-top driving. The driver information system integrates a lap timer for recording circuit times. Most of the interior is a sportily cool black; many controls shine in aluminum look.

Among the highlights of the standard equipment are seats covered with Fine Nappa leather, the aluminum door sills, the concert radio system with seven speakers, the xenon plus headlights, the LED tail lights, the automatic air conditioning system, the alarm system, the automatic top, the rollover protection system and the wind deflector. Metallic paint and heated seats are also standard.

Audi also offers an array of fine options – power seats, an interior lighting package, hill hold assist, cruise control, deluxe automatic air conditioning, a storage package and the high-beam assistant. All leather for the seats is colored with pigments that reflect the infrared component of sunlight, greatly reducing the heating of the interior.

Multimedia options include an excellent sound system from Bang & Olufsen with 450 watts of power, the Audi music interface for easily connecting an external player and a Bluetooth cell phone preparation. The navigation system plus is characterized by its MMI operating logic and a high-resolution 6.5-inch display. It can be combined with a reversing camera.

An enticing innovation from Audi is the seatbelt microphone for the hands-free unit and the speech dialogue system, which makes it possible to talk on the phone even with the top down on the highway. Both seatbelts house three small, flat microphones. At least one of them is ideally positioned relative to the speaker when the belt is on. There is a fourth microphone in the windshield frame.

Extreme individualists can choose from a wealth of exclusive options, the lion's share of which are provided by quattro GmbH. These include leather seat coverings in a wide variety of colors and grades, aluminum-look pedals, the carbon package for the exterior, inlays in carbon and piano finish black, Alcantara for the headliner and the luggage compartment lining and the custom luggage set.

The R8 Spyder 4.2 FSI quattro will be rolling into German showrooms in the third quarter of 2010. Sales will be starting soon at a base price of €121,000.

Audi today launched a bold new design for the Autonomous Audi TTS Pikes Peak, as research surrounding the car that can drive itself enters a crucial stage before high-speed test runs up Pikes Peak in Colorado this fall.

With the changed appearance, the Autonomous Audi TTS Pikes Peak is now squarely aligned with Audi cars that made motorsports history a generation ago in the Pikes Peak Hill Climb and other rally racing events.

The new emphasis for the project also honors quattro® technology, which has played an instrumental role in Audi racing successes, has served as a leading example of the progressive engineering found in Audi passenger vehicles and is integral to the handling of the Audi TTS research car. This year marks the 30th anniversary of quattro on the world automotive stage.

The challenge and heritage of Pikes Peak

The association between Pikes Peak and this research project relates to the original goal of developing advanced algorithms and actuation systems that would allow a car to complete a driving course without a human behind the wheel.

The partners in developing this technology – the Stanford University Dynamic Design Lab (DDL), the Electronics Research Lab (ERL) for the Volkswagen Group in Palo Alto, Calif., and Oracle Corp. – chose the part-pavement, part-gravel route of the storied Pikes Peak race to prove the project's capabilities.

"Our aim from the start has been to show how the future of driver assistance technologies will lead to dramatic improvements in traffic safety and saving lives," said Dr. Burkhard Huhnke, Executive Director, ERL. "With this project we are working on electronics that will help drivers steer their way out of dangerous situations. But first we need to create programs that would replicate the quick decisions and rapid maneuvers of the best rally racers under the most difficult road conditions."

The connection with rally racing provided another key inspiration to the project team.

"Many of the leading automotive technologies we see in our cars today evolved out of motorsports," said mechanical engineering Associate Professor Chris Gerdes, director of the Center for Automotive Research at Stanford, in Palo Alto, Calif. "This is because racing pushes emerging technologies to the limits before they can be adopted more broadly."

How the Autonomous TTS Pikes Peak works

The Autonomous Audi TTS Pikes Peak is based on a street-ready Audi TTS sports car. The team chose the TTS because its native systems, including a drive-by-wire throttle and a semiautomatic DSG gearbox were a good fit with the electronics that allow the car to drive without human input.

The computing hardware added to the TTS research car isn't significantly more elaborate than what can be found in a standard laptop. The car currently uses two computers in its trunk – one running safety critical algorithms using Oracle's Real Time Java (Java RTS). The other runs vehicle dynamics algorithms. The two sets of algorithms are what enable the TTS to drive at the limits of handling on a variety of surfaces, speeds and conditions.

The differential GPS system is capable of keeping the TTS within two centimeters of the center line of a normal course; researchers are planning on a one-meter margin on Pikes Peak due to the extreme conditions.

The Autonomous Audi TTS Pikes Peak gained global recognition last year with a Web video that showcased the car's ability to execute complex maneuvers on Utah's Bonneville Salt Flats without a human behind the steering wheel.

In the Pikes Peak Hill Climb, Audi legends were born a generation ago. Audi rally cars, such as the Audi Sport quattro S1 Pikes Peak, employed the all-wheel drive technology to win the 12.42-mile "Race to the Clouds" in convincing fashion. The drivers of those Audi quattro rally cars – Bobby Unser, Walter Roehrl and Michele Mouton – earned places in motorsports history at Pikes Peak. In fact, the researchers from Stanford and the Volkswagen Group's Electronics Research Laboratory in Palo Alto, Calif., nicknamed the project "Shelley" after Mouton and her racing exploits.

The Sport quattro S1 also inspired the "S" range of performance models, such as today's critically acclaimed Audi S4 sedan.

Design challenge – combining the past and the future

Tying the Audi traditions into a look for the Autonomous Audi TTS Pikes Peak became an engaging assignment for Audi designers at the company's Design Center California in Santa Monica. Several options emerged, including an art car look that depicted the Pikes Peak route in a topographic map covering the body of the TTS.

For the design that was selected, the goal was to pay homage to the past, while conveying the leading-edge technology that defines the TTS research car. Designers decided to give the rally car themes from the 1980s a forward-looking twist, said Sangyup Lee, Chief Designer (Group Exterior) at VW/Audi Group Studio California.

The original rally cars, for example didn't feature a large four rings logo on their roofs. But the designers used that design cue from modern Audi DTM racing cars in Europe so the brand image would be evident in aerial photos and videos.

"We were very much inspired by the Pikes Peak race cars," noted Raul Cenan, Lead Designer on the TTS project. "But there was very different technology used in those cars overall. So we decided to go with more modern elements that were heritage-inspired."

Planned Timeline for the Autonomous Audi TTS Pikes Peak

The highlight of the months ahead for the Autonomous Audi TTS Pikes Peak is the planned high-speed testing up Pikes Peak in the fall, weather conditions permitting.

During testing the Pikes Peak course would be divided into segments, which the TTS research car would drive at progressively increasing speeds. Certification of the testing would be done by an independent motorsports organization.

Later in the fall, also weather permitting, the Autonomous Audi TTS Pikes Peak plans to make a Guinness Book of World Records land speed attempt at the El Mirage Lake dry-lake bed in southern California or another nearby location.

Officials from the Guinness Book would certify whether the TTS research car can establish a record in the new category of fastest speed in an autonomous vehicle.

Audi presents a limited-production version of it R8 high-performance sports car, the R8 GT. The output of its 5.2-liter V10 has been increased to 412 kW (560 hp); vehicle weight has been reduced by roughly 100 kilograms (220.46 lb). The R8 GT accelerates from zero to 100 km/h (62.14 mph) in 3.6 seconds and reaches a top speed of 320 km/h (198.84 mph).

The R8 high-performance sports car has been a winner from the very beginning. This applies to both the production models, winners of the “World Performance Car” Award in 2008 (R8) and in 2010 (R8 V10), and to the race car, the R8 LMS, which won 23 races in its first season and claimed three championships. The genes of the race version are now coming to the street – in the R8 GT. The exclusive series is limited to 333 units. Each R8 GT has a badge with its production number on the shift lever knob.

Consistent use of lightweight construction: 100 kilograms (220.46 lb) trimmed

The production R8 5.2 FSI quattro is already a shining example of the Audi’s lightweight construction philosophy. Its aluminum Audi Space Frame (ASF) body weighs only 210 kilograms (462.97 lb). The aluminum body panels are joined to the frame of extruded profiles and cast nodes by means of positive and friction connections. The engine frame is made of ultra lightweight magnesium.

The ASF body is largely hand-built at the Neckarsulm plant in a complex manufacturing process. The extremely high strength of the body is the basis for the high-performance sports car’s precise handling, and it also offers good vibration comfort and first-rate crash safety.

Thanks to the ASF body, the production R8 5.2 FSI quattro weighs only 1,625 kilograms (3,582.51 lb) – with quattro permanent all-wheel drive and optional R tronic transmission. This made it all the more difficult for the engineers to once again achieve substantial weight savings. They took an elaborate approach involving every aspect of the vehicle, and in the end the scales came to rest at 1,525 kilograms (3,362.05 lb).

The windshield of the R8 GT is made of thinner glass; the bulkhead between the passenger cell and engine compartment, as well as the window in the rear hatch are made of strong, lightweight polycarbonate. These three modifications saved nine kilograms (19.84 lb). The fixed rear wing is good for an additional 1.2 kilograms (2.65 lb); thinner sheet metal and additional cutouts shaved 2.6 kilograms (5.73 lb) from the aluminum hatch over the 100 liter (3.53 cu ft) luggage compartment at the front of the car.

The long rear hatch is made of carbon fiber-reinforced plastic (CFRP) – an advantage of 6.6 kilograms (14.55 lb). The rear bumper and the sideblades of this same material save an additional 5.2 and 1.5 kilograms (11.46 and 3.31 lb), respectively. With its minimal weight and extremely high strength, CFRP is the ideal material for a high-performance sports car, and Audi has broad-based expertise in its use.

The engineers also fought to shave every possible gram of weight from the technical components of R8. They shaved one kilogram (2.20 lb) from the power brake system, four kilograms (8.82 lb) from the aluminum caps of the brake discs and 9.4 kilograms (20.72 lb) from the battery. The engineers also found 2.3 kilograms (5.07 lb) in the air intake module and 2.8 kilograms (6.17 lb) in the insulation of the engine compartment.

The interior also harbored substantial weight-savings potential. The new, lightweight carpeting accounts for 7.9 kilograms (17.42 lb); the bucket seats with a chassis of glass-reinforced plastic (GRP) account for 31.5 kilograms (69.45 lb). Numerous additional detailed measures targeted the interior, the exterior and the technology, such as higher-grade, lighter steel for the exhaust system’s tailpipes.

Even sharper and more effective: the design

The design of the Audi R8 GT is the expression of concentrated power – a beautiful, technical sculpture measuring 4.43 meters (14.53 ft) long, 1.93 meters (6.33 ft) wide and only 1.23 meters (4.04 ft) high. The exterior underwent numerous modifications that further sharpened the appearance. Many of them also reduce the weight and enhance the aerodynamics. The R8 GT produces even more downforce when driven fast than the production model – without any increase in the Cd value (0.36) or frontal area (1.99 m2) (21.42 sq ft).

The frame of the single-frame grille, its struts and the slats in the air intakes are finished in matt titanium gray; the grille is painted matt black. The splitter under the bumper has a double lip and is made of carbon. Slender, curved flics at the corners of the nose increase the downforce on the front axle and are also made of a carbon fiber composite.

One highlight of the R8 GT are the standard LED headlights, which use light-emitting diodes for all functions. They produce bright, homogeneous light, have a long service life and low energy consumption. The headlights also have an attractive and distinctive appearance. The daytime running lights each comprise 24 LEDs and appear as a continuous band. The reflectors are reminiscent of open mussel shells.

The defining element of the side view are the sideblades, which direct air to the engine and in the R8 GT are also made of matte carbon. The same material is used for the reduced-size housing of the side mirrors, which are mounted on an aluminum base. The 19-inch wheels feature an exclusive five twin-spoke Y design in a titanium-look finish. The front fenders sport “GT” badges.

The modifications to the rear of the car are particularly apparent, beginning with the fixed wing of matte carbon. The ventilation louvers on both sides of the rear hatch and the CFRP bumper, which integrates the large, round tailpipes and vents for the wheel wells, have been redesigned. The larger diffuser is made of carbon fiber composite; the license plate bezel and the wide slats at the rear are in matte titanium gray. The tail lights, which also use LED technology, have dark housings with panes of clear glass.

Audi offers the R8 GT in a choice of four body colors: Samoa Orange metallic, Suzuka Gray metallic, Ice Silver metallic and Phantom Black pearl effect

Breathtakingly powerful: the 412 kW (560 hp) 5.2 FSI

The modified V10, whose cylinder head covers are painted red, gives the Audi R8 GT breathtaking performance. The R8 GT sprints from a standing start to highway speed in 3.6 seconds, and from zero to 200 km/h (124.27 mph) in 10.8 seconds. And the thrust does not let up until the top speed of 320 km/h (198.84 mph) is reached.

Changes to the engine electronics coaxed an additional 26 kW from the ten-cylinder, which now produces 412 kW (560 hp) from a displacement of 5,204 cc. The torque curve peaks at 540 Nm (398.28 lb-ft) at 6,500 rpm, 10 Nm (7.38 lb-ft) more than in the production version. The V10 has a specific power output of 79.2 kW (107.6 hp) per liter displacement. Its power-to-weight ratio is 3.70 kilograms (8.16 lb) per kW or 2.72 kilograms (6.00 lb) per hp. The engine redlines at 8,700 rpm.

The long-stroke engine (bore x stroke 84.5 x 92.8 millimeters [3.33 x 3.65 in]), which is hand-built at the factory in Györ, Hungary, features a crankcase made of a aluminum-silicon alloy that is both lightweight and very strong. A bedplate – a frame for the crankshaft bearing bridges – further enhances its rigidity. The complete engine weighs only 258 kilograms (568.79 lb). It is characterized by a cylinder angle of 90 degrees and dry-sump lubrication, which uses a highly efficient oil pump module. Both solutions lower the center of gravity and thus improve driving dynamics.

The crankshaft is designed as a common pin shaft. The connecting rods of the opposing pistons engage a common crankpin, resulting in alternating firing intervals of 54 and 90 degrees. This unique rhythm gives the V10 its fascinating sound – a grand, technical music very much like that in racing. Two flaps in the exhaust system modulate its volume and tone as a function of load and engine speed.

The normally aspirated engine consumes an average of 13.7 liters of fuel per 100 km (17.17 US mpg) – very good fuel economy given the tremendous power. The FSI gasoline direct injection system injects the fuel into the combustion chambers at up to 120 bar of pressure. The turbulent mixture cools the cylinder walls, enabling a compression ratio of 12.5:1. A variable intake manifold and the continuous adjustment of the chain-driven camshafts ensure that the combustion chambers are fully filled. Flaps in the intake ports facilitate the formation of the mixture by inducing a tumbling motion in the inflowing air.

The drivetrain: uncompromising traction

Gear changes in the R8 GT are handled by the R tronic sequential manual transmission. The electrohydraulic clutch and switching unit receive their commands electronically. It changes its six gears much faster than a skilled driver could – within a tenth of a second at high load and engine speed.

The electronic management system offers an automatic mode with the Sport and Normal characteristics, and two manual levels. It is controlled using the short gear selector lever on the center tunnel and two paddles on the steering wheel. Maximum thrust when starting is ensured by Launch Control – a program that manages full acceleration with high engine speed and minimum wheel slip when starting.

quattro permanent all-wheel drive is the ideal technology for a high-performance sports car. The central viscous coupling located at the front differential sends 15 percent of the power to the front axle and 85 percent to the rear axle during normal driving. This split harmonizes perfectly with the Audi R8 GT’s 43:57 percent weight distribution. The coupling sends as much as 30 percent of the power to the front wheels within milliseconds, if necessary. A mechanical locking differential at the rear axle further improves traction. It provides up to 25 percent lockup when accelerating and up to 40 percent on the overrun.

Chassis even tauter and more precise

The Audi R8 GT high-performance sports car is a driving machine with breathtaking lateral acceleration and lightning-fast, nearly instantaneous reactions. Its engine is mid-mounted close to the vertical axis; its mass is almost negligible during fast direction changes. The R8 GT is dynamic, precise and stable in almost every situation.

The chassis follows the classic racing design – double wishbones made of aluminum locate the wheels. The hydraulic, power-assisted rack-and-pinion steering has a direct 16.3:1 ratio and connects the driver closely and precisely with the road. A manually adjustable coilover suspension, which lowers the body by as much as 10 millimeters (0.39 in), is standard. Higher front and rear wheel camber rates make the handling a tick more agile than with the standard model.

The 19-inch forged wheels are 8.5 J x 19 up front and 11 J x 19 at the rear, and are shod with size 235/35 and 295/30 tires, respectively. Audi will mount 305/30 tires together with optional wheels on the rear axle upon request. Cup tires, which offer the ultimate in performance on dry roads, are available for racing enthusiasts.

Audi mounts internally ventilated, carbon fiber ceramic brake disks standard. They are extremely durable and abrasion-resistant as well as particularly lightweight. Together they weigh nine kilograms (19.84 lb) less than their steel counterparts of the same size. They measure 380 millimeters (14.96 in) in diameter up front and 356 millimeters (14.02 in) at the rear. The friction rings are bolted to the stainless steel caps via elastic elements. Red anodized aluminum brake calipers – with six pistons up front – are exclusive to the R8 GT.

The ESP stabilization program has been specially tuned to the R8 GT and can be switched into a Sport mode at the push of a button to allow spectacular, but safe, oversteer when accelerating out of a corner. The driver can deactivate the system entirely for a trip to the race track.

Exclusive and dynamic: interior and equipment

At Audi, reducing weight means increasing performance and efficiency, but not sacrifice. The Audi R8 GT, which Audi sells in Germany for €193,000, comes with an automatic climate control system and power windows, a navigation system with MMI operating logic and a powerful sound system. A 465 watt, ten-channel Bang & Olufsen sound system, a CD changer and the Audi Music Interface are available as options. As always with Audi, the interior shows loving attention to detail. Rich materials spoil the occupants with a fine look and feel.

The ergonomic interior is adorned in sporty black and dark gray. The steering wheel, the headliner, the roof posts, the knee pad, the parking brake lever and the bucket seats are covered with Alcantara accented with contrasting stitching. A synthetic sharkskin-look material that feels slightly rough to the touch is applied to the bulkhead, the door liners, the instrument cowl and the dashboard. The “monoposto” – the arch in the cockpit – is made of matt carbon.

The instrument cluster features white dials with “R8 GT” badges. The newly designed selector lever is made of CFRP and aluminum; the center tunnel and the door liners sport decorative inlays in the body color. The door sills feature trims of matt aluminum decorated with the “R8 GT” logo.

A number of exclusive features are available as options for the R8 GT. Exterior options include two alternative wheels, a body-color front splitter and a CFRP engine compartment lining. Carbon elements on the doors, the tunnel, in the cockpit and on the instrument panel are available as interior options. Others include a multifunction leather steering wheel, seat belts in red, orange or gray, floor mats with the “R8 GT” logo and CFRP door sill trims illuminated in red. If desired, Audi will fit seats with carbon frames, which are somewhat lighter than the CFRP shells. The Alcantara seat covers are optionally available with an embroidered “R8 GT” logo.

A race package is available for racing enthusiasts. It includes a bolt-in roll bar in red or black, which has both road and type approval, as well as road-approved four-point belts in red or black, a fire extinguisher and a kill switch for the battery. An optional front bar module for motorsports evens includes a rotary lock for the four-point seatbelt and turns the roll bar into a full cage. Buyers looking for more comfort and convenience can choose cell phone preparation with an innovative belt microphone. Audi also offers a full leather package, control elements in leather with contrasting stitching and a cruise control system as options. The parking aid is included with the standard equipment.

The new A8 is a concentrated high-tech package that confirms Audi claim to technical leadership – "Vorsprung durch Technik". And now the brand is introducing the top version of its flagship model. The A8 L W12 quattro, with a long wheelbase and a twelve-cylinder engine, sets new standards of luxury, dynamism and efficiency in the top automobile manufacturing league. The Audi A8 L is being launched with a twelve-cylinder engine, but by the end of the year will be available with all the engines currently offered for the A8.

What's fascinating about the A8 L is its supremely powerful presence; its design is clearly derived from the brand's genes and yet has undergone further refinement. The long wheelbase does not disturb its taut outlines, which remain as athletic as they are elegant.

With an overall length of 5,267 millimeters (17.28 ft), the new Audi A8 L is 130 mm (0.43 ft) longer than the regular version. The wheelbase has grown by the same amount, to 3,122 mm (10.24 ft). The width remains unchanged at 1,949 mm (6.39 ft); the height has increased by 2 mm (0.08 in) to 1,462 mm (4.8 ft). Audi's new top model is both longer and wider than its main long-wheelbase competitors.

The A8 L has a body built from aluminum using the Audi Space Frame (ASF) principle and therefore weighing about 40 percent less than a comparable steel body. The ASF body structure is built up from cast elements, extruded sections and sheet aluminum, with integral B-posts made from form-hardened ultra-high strength steel. This body's tremendous rigidity is the key to the car's precise handling, low interior noise levels and high passive safety for the occupants in the event of an accident.

Among the high-end technologies featured on the A8 model line are the optional LED headlight units (standard on the A8 L W12 quattro) with all lighting functions performed by LEDs. With this bright, high-efficiency light, Audi opens a new chapter in the history of automobile lighting technology.

Subtle visual details distinguish the A8 L W12 quattro from the other cars in this model line. The single-frame radiator grille with integral grid structure has a high-gloss black paint finish and special chromed horizontal bars. There are also chromed inserts of new design in the air inlets, and chromed applications on the exterior mirrors. W12 badges are displayed on the single-frame grille and at the rear of the car. The exhaust system has two trapezoidal-pattern tailpipe trims neatly integrated into the rear bumper.

Abundant space: Rear-seat area

The full extra length of this sedan benefits rear-seat passengers. The back doors are longer, for even more convenient entry, and the space available inside can only be described as opulent. Rear passenger comfort can be enhanced even more if two separate power-adjustable seats are ordered. These can be heated, ventilated and adjusted in a variety of ways: forward and back, seat cushion depth and seat back angle with top section adjustable separately. There is also a fully adjustable lumbar support. The front passenger's seat can also be moved from the rear if extra space is needed.

Between the individual rear seats that are standard equipment in the Audi A8 L W12 quattro a full-length console can be ordered as an optional extra; it extends back from the center tunnel to the rear shelf, and can be specified with integral items such as a folding table or a refrigerator. Separate controls for the rear air conditioning are also standard. The luxury four-zone automatic air conditioning is controlled by no fewer than 25 adjusting motors.

Another high-end feature of the long-wheelbase Audi A8 is the reclining seat behind the front passenger's seat. The angle of the seat cushion can also be adjusted. The occupant can be massaged by ten air-filled compartments; four programs can be selected at a remote control. The feet rest on a power-adjustable support at the base of the front passenger seat back. Heating, ventilation and the luxury head restraint are integral features of the reclining seat. A folding table, additional wood and leather trim, a refrigerator and a Rear Seat Entertainment system with two 10.2-inch screens are among the features that promote relaxed travel or alternatively concentrated work in this mobile lounge.

Fine materials: Interior design

The quality of workmanship in the A8 L is simply first-class – from the restrained ambient lighting through the accurately fitted switches with their precise click action. Fascinating aspects of the car's interior are the slim, clear outlines and the stylish materials with their modern look.

Audi design selection brass beige carefully combines well-matched colors with individual materials and comfort-oriented equipment items. The roof-mounted grab handles and rear console have additional fine wood trim.

Valonea leather is tanned exclusively with plant extracts and is especially soft and able to "breathe" actively. Audi also supplies a loose cushion for rear-seat passengers' use. Like the head restraints and the selector lever for the eight-speed tiptronic automatic transmission, it is trimmed with buckskin that is exceptionally soft and supple but also hard-wearing.

Another optional extra, the panoramic glass roof, has two glass panels that allow plenty of light to reach the car's interior. Both sections can be tilted up and the front one also opened extra-wide. Sun blinds are provided for both panels to keep out direct sunlight.

The Audi A8 L W12 quattro: Splendor and efficiency

Twelve cylinders are the ultimate engine configuration, a tradition that still applies in the large luxury car class. The first-generation A8 was available with an engine of this type from 2001 on, and a developed version could be obtained from 2004 on in the following model. Audi's engineers have now thoroughly revised the W12. Its displacement has been increased, and gasoline direct injection boosts its output and its efficiency.

The 6.3 FSI engine has an output of 368 kW (500 hp) and delivers its peak torque of 625 Nm (460.98 lb-ft) at engine speeds at 3,250 rpm. It gives the long-wheelbase Audi A8 the kind of performance normally expected of a sports car: it sprints from 0 to 100 km/h (62.14 mph) in only 4.9 seconds and effortlessly reaches its governed top speed of 250 km/h (155.34 mph).

A fascinating flow of power is available in every situation, but the fuel consumption too sets new standards: the EU cycle test result is only 12.0 liters per 100 kilometers (19.6 US mpg), a figure well below that of competitors' cars with V12 engines. The previous 6.0-liter engine, which had a power output of 331 kW (450 hp), recorded a fuel consumption of 13.6 l/100 km (17.3 US mpg) – the difference of 1.6 l/100 km is equivalent to a 12 percent improvement.

The engine is known as the W12 because of its unusual layout: it has four rows of three cylinders with a 15-degree included angle between the two offset rows of cylinders in each broad cylinder block. The V angle between the two blocks is 72 degrees. This layout makes the W12 engine exceptionally compact: only just over 50 centimeters (19.69 in) long and therefore distinctly shorter than a V8. Height and width are both in the region of 70 centimeters (27.56 in).

The W12, in its latest form with a displacement of 6,299 cc, is an undersquare design. Its bore and stroke are 86.0 and 90.4 millimeters (3.39 x 3.56 in) respectively. Compared with the previous version the engineers have enlarged the cylinder bore. The forged crankshaft has a 12-degree angle of crankpin offset, so that the mixture in the 12 cylinders is ignited at the ideal interval of 60 degrees. The engine therefore runs exceptionally smoothly, and the car's occupants are unlikely to sense any of this supreme power at work unless it is at high engine speeds and severe loads.

The W12 engine weighs only 247 kilograms (545 lb), an impressive value to which the crankcase makes a major contribution. This is a lightweight, high-strength aluminum-silicon alloy casting with a gray cast iron lower cross-member into which the bearing pedestals are embedded. The pistons are forged from a high-strength light alloy and have angled crowns because of their V position in the cylinder blocks.

Each of the W12 engine's aluminum cylinder heads contains two camshafts; these can be repositioned hydraulically by an amount equivalent to 52 degrees of crankshaft rotation. Altogether, the four camshafts operate 48 valves by way of low-friction roller cam followers, and are themselves driven by chains from an intermediate shaft.

For use in the long-wheelbase A8, Audi's engineers have converted the W12 engine to FSI gasoline direct injection. This involved considerable modifications to the cylinder heads. Fuel is injected into the combustion chambers at a pressure of up to 130 bar. A high 11.8:1 compression ratio boosts power output and efficiency. The inlet ports are specially shaped to impart swirl to the incoming airflow and make combustion more efficient.

The W12 engine's low fuel consumption compared with its competitors is to a large extent due to Audi's modular efficiency platform. These are used in the entire A8 model line. The crankshaft and timing chains have been intensively optimized to reduce friction, and a recuperation system recovers energy that would otherwise be wasted when the car is braked. The innovative thermal management system shuts down the coolant circuit for a time after the cold engine has been started. This warms up the engine oil more rapidly and shortens the operating period in which friction is still high.

Safe and sporty: Transmission

The transmission makes a major contribution to ensuring the high efficiency of the Audi A8 L. The eight-speed tiptronic shifts smoothly and quickly, with the individual gears closely spaced but with a generous overall spread from low to high. Gear shifts are performed electronically ("shift by wire") from an elegant yacht-style selector lever or at steering wheel paddles.

The center differential, the main component in the quattro permanent all-wheel drive train, divides the torque flow from the engine in a sporty manner, with 60 percent to the rear axle and 40 percent to the front in regular driving conditions. But if the situation changes, up to 60 percent of the torque can be sent to the front, or 80 percent to the rear. An optional sport differential splits the torque input actively between the left and right rear wheels.

Maximum precision: Chassis

Thanks to its advanced chassis design, the long-wheelbase Audi A8 brings together the silky, refined smoothness of a true luxury car and the handling of a sport sedan. The wheel control arms are made of aluminum. The front suspension uses five locating arms at each wheel; the controlled-track wishbone rear suspension ensures a supremely comfortable ride. The servotronic power steering system has a direct operating ratio and operates at high efficiency.

The adaptive air suspension with controlled damping is standard equipment and is integrated into the Audi drive select dynamics system. With this system the driver can choose between four different operating settings of the engine, the eight-speed tiptronic transmission, the servotronic power steering, the optional sport differential and the Audi pre sense basic safety system. An additional module is the dynamic steering system, which varies its gear ratio steplessly according to road speed.

The A8 L W12 quattro runs on 19-inch alloy wheels with a 15-spoke design reserved for this model, and size 255/45 tires. As an optional extra 20-inch wheels can be chosen, and even 21-inch wheels can be obtained from quattro GmbH.

The A8 L W12 quattro, the new top model, naturally has a high-performance brake system, with ventilated disks at all four wheels. The front disks are 400 mm (15.75 in) in diameter, with 356 mm (14.02 in) disks at the rear. To dissipate heat and reduce weight, stainless steel pins connect the steel friction rings with the aluminum disk centers. The calipers have a matt black paint finish.

Dynamic intelligence: Communication and assistance systems

This large sedan features an exemplary control concept. Although there are so many functions available, they can be selected in an easily understood, ergonomically correct way. Two large monitor screens, one on the instrument panel and one on the center console, acts as control centers and display their information as high-resolution 3D graphics.

The A8 has a pioneering innovation on board: the optional MMI navigation plus, which operates with the aid of a high-capacity hard disk, has a touch-sensitive control panel known as MMI touch. The driver inputs his or her navigation destination or a telephone number simply by writing the letters or numerals on the pad with a finger. Acoustic feedback makes this possible without taking one's eyes of the road.

The high-end navigation system cooperates with the assistance and safety systems in an innovative way. It registers the topography of the road in advance and makes this data available to the control units for the automatic transmission, headlights and adaptive cruise control with Stop & Go function. Thanks to their advanced intelligence, these systems can identify complex scenarios and offer the driver support in good time.

The adaptive cruise control system operates at any speed up to 250 km/h (155.34 mph) and responds even more flexibly and smoothly than before. The Audi side assist system, which helps the driver to change lanes, and Audi lane assist which detects any departure from the chosen lane, also have new and additional performance features.

The night view assistant uses a thermal imaging camera to identify persons on the road ahead of the car. If it considers the situation to be potentially dangerous, the image of the person on the road is shown in red and a warning signal is heard. The Audi pre sense safety system is also closely linked to the assistance systems. It is available in several stages: the full version brakes the car automatically in order to minimize the consequences of a nose-to-tail collision.

In the multimedia area, Audi can also supply many attractive modules. These include a Bang & Olufsen Advanced Sound System with an output rating of more than 1,400 Watts and 19 speakers, and the Rear Seat Entertainment system. This has an MMI control panel on the console between the rear seats and provides access to all the infotainment functions on board this large luxury sedan.

The new Online services in cooperation with Google use the car phone to capture news and current information on the weather or points of interest (POI) from the Internet. Later this year an UMTS module will be available: this fast data link can supply images and information from Google Earth to the monitor screen and combine them with the navigation route. The driver can use all these services with his or her cell-phone contract.

With the delivery of the first customer cars, Audi AG’S GT3 customer sport program has reached the next phase. By mid-April, 20 Audi R8 LMS vehicles will have been handed over to the teams that are planning to run the GT3 race sports car in various national and international racing series and in the two 24-hour races at the Nürburging and at Spa-Francorchamps in the 2010 season.

After its successful 2009 debut year in which Audi Sport partners clinched three champions titles and 23 victories in 76 racing commitments the Audi R8 LMS will now be handed over to customers for its second season, as planned. Last week United Autosport from Great Britain was the first team to receive its two R8 LMS cars.

To offer customer teams a perfect a race car as possible, Audi Sport is making use of the opportunity offered by the GT3 regulations and will obtain FIA homologation of an evolution-version of the R8 LMS which features numerous technical improvements compared with last year’s model. The previous vehicles will be brought up to the current level by an update kit and teams can thus continue to run them.

“During our evolution project we primarily focused on service life and maintenance-friendliness,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich. “All the experience we gathered last season with the help of our partners has been fed into the evolution-version. We’re convinced that we’re handing over a reliable and easy to handle vehicle to our customers that embodies the high quality standards of the Audi brand.”

Certain details of the chassis and suspension have been revised. The capacity of the engine’s cooling system has been improved even further so that the R8 LMS can also be used in extreme ambient temperatures without any problems. The complex electronics as well as the exhaust system have been optimized for use in racing. The newly developed six-speed racing transmission is particularly maintenance-friendly. It allows wearing parts to be inspected through an opening in the housing. The transmission does not have to be dismantled for this purpose.

Over the past few months the evolution-version of the Audi R8 LMS was extensively tested on various race tracks and rigs and its durability proved in several endurance tests.

The final version of the Audi R8 LMS is available at a price of 298,000 euros plus VAT. The annual production for 2010 is already sold out. The delivery of vehicles for the 2011 season will start at the end of this year.

Fascination taken to a new level of intensity: The Audi R8 Spyder 5.2 FSI quattro combines breathtaking performance with the experience of open- top driving. The 386 kW (525 hp) V10 engine accelerates the high- performance sports car with the lightweight cloth top to 100 km/h (62.14 mph) in 4.1 seconds on its way to a top speed of 313 km/h (194.49 mph). The R8 Spyder 5.2 FSI quattro features a fascinating package of technologies, including the Audi Space Frame (ASF) made of aluminum and carbon fiber composite, quattro permanent all-wheel drive, LED headlights and the innovative seatbelt microphone.

The R8 Spyder 5.2 FSI quattro captivates from the very first glance. Its lines offer a unique interpretation of the dynamics and emotion of a high-performance sports car. Two distinctive silver cowls, into which the large air intake openings are integrated, give the long back a powerful profile. Unlike the Coupé, the R8 Spyder has classic air intakes behind the doors. The rear side panels and the large cover over the storage compartment for the cloth top are made of a carbon fiber composite.

The R8 Spyder 5.2 FSI quattro sports a cloth soft top in classic Audi style. The soft top’s approximate weight is a mere 42 kilograms (92.59 lb); it thus keeps the vehicle’s total weight and center of gravity low. When closed it melds harmoniously into the design line – it ends in two slim fins that extend toward the rear and have a contour similar to that of the Coupé hard top.

The top is suitable without restriction for high-speed driving and is quiet. With the standard electrohydraulic motor, the top opens and closes within 19 seconds, even while driving at speeds up to 50 km/h (31.07 mph). The heated glass window is integrated separately into the bulkhead and can be raised and lowered via a switch with the soft top up or down. Audi also provides a wind deflector that can be installed in just two steps.

The bulkhead includes integrated rollover protection in the form of two pretensioned plates. The aluminum Audi Space Frame (ASF) body of the R8 Spyder is reinforced at important locations, yet it tips the scales at a mere 216 kilograms (476.20 lb) – just six kilograms (13.23 lb) more than the Coupé. Equipped with a manual transmission, the high-performance sports car weighs only 1,720 kilograms (3,791.95 lb).

Prodigious power: the drivetrain

The new top-of-the-range Audi offers incredible performance. The free-breathing V10 with the aluminum crankcase features direct gasoline injection. The 12.5:1 compression ratio that the FSI concept enables contributes to the high performance and good efficiency. Dry sump lubrication, another motorsport technology, ensures the reliable supply of oil even at the maximum lateral and longitudinal acceleration.

The 5.2-liter engine produces 530 Nm (390.91 lb-ft) of torque at 6,500 rpm and 368 kW (525 hp) at 8,000 rpm. Its specific power output is 100.9 hp per liter of displacement; each hp only needs to move 3.3 kilograms (7.28 lb) of weight. The R8 Spyder 5.2 FSI quattro accelerates from zero to 100 km/h (62.14 mph) in 4.1 seconds on its way to a top speed of 313 km/h (194.49 mph). The engine offers amazing thrust and hangs tenaciously on the throttle in every situation accompanied by that unmistakable ten-cylinder Audi sound.

Audi offers the R tronic sequential six-speed transmission as an option. This has a fully automatic and a manual mode, in which the driver can change gears in an instant using paddles on the steering wheel. Launch Control manages engagement of the clutch for maximum acceleration. The rear-biased quattro permanent all-wheel drive system transfers power to the road with supreme ease. Together with the locking differential on the rear axle, it provides significantly greater traction, stability, cornering speed and precision.

Motorsport technology can also be found in the chassis of the Audi R8 Spyder 5.2 FSI quattro. There are double triangular wishbones made of aluminum at all four wheels, and the hydraulic rack-and-pinion power steering conveys highly- precise road feel. The standard suspension includes the high-end Audi magnetic ride technology, in which the shock absorbers adjust their response to the road conditions and the driver’s style within milliseconds. A sports suspension with conventional shock absorbers is available as an option.

The R8 Spyder 5.2 FSI quattro rolls on 19-inch wheels shod up front with 235/35 tires and 295/30 tires in the rear. The four brake discs are internally ventilated and perforated, and are gripped by a total of 24 calipers. Optionally available from Audi are large carbon fiber-ceramic discs that are lightweight, robust and long-lived. The ESP stabilization system has a Sport mode and can also be completely deactivated.

Comfortable: interior, equipment and trim

The open-top two-seater features a generously spacious interior. The ring of the leather-wrapped, multifunction sports steering wheel is flattened at the bottom, and the power seats guide and support the body perfectly. Quality of fit and finish is extraordinary; the controls are clear and logical; and the driver information system includes a lap timer. The rear bulkhead includes a storage compartment with three bins, and the luggage compartment at the front of the car can hold 100 liters (3.53 cubic ft) of luggage.

Equipment highlights include an excellent sound system from Bang & Olufsen, deluxe automatic air conditioning and heated seats. The leather seat coverings are specially pigmented to reduce heating as a result of the sun’s rays. The standard navigation plus system with MMI control logic features impressively high resolution and fast route calculation.

Also included standard in the Audi R8 Spyder 5.2 FSI quattro are the LED headlights – light-emitting diodes are used for the low beams, the high beams, the daytime running lights and the turn signals. The LED headlights not only look like technological works of art, they also offer substantial practical advantages with their excellent light distribution, long service life and extremely low energy consumption.

Among the exclusive optional equipment available for the new R8 Spyder 5.2 FSI quattro is the innovative seatbelt microphone for the hands-free unit, which makes it possible to make telephone calls even with the top down on the highway. Integrated into each of the two belts are three small microphones; a fourth is mounted on the windshield frame. Audi will begin selling the open two- seater in Germany in the next few days at a base price of 156,400 euros.

Performance and emotion

The Audi R8 Spyder 5.2 FSI quattro

Exceptional performance, breathtaking dynamics and the intense experience of open-top driving: Audi introduces the R8 Spyder 5.2 FSI quattro. Its outer skin is made of carbon fiber composite in some sections, and a lightweight cloth top is integrated into the aluminum Audi Space Frame (ASF). The V10 engine produces 386 kW (525 hp) and launches the open-top two-seater to 100 km/h (62.14 mph) in 4.1 seconds on its way to a top speed of 313 km/h (194.49 mph).

Convertible top and body

The top of the R8 Spyder 5.2 FSI quattro is made of cloth – an Audi classic and an uncompromising solution for a high-performance sports car. The soft top’s approximate weight is a mere 42 kilograms (92.59 lb); it thus keeps the vehicle’s total weight and center of gravity low. When closed it melds perfectly into the design line – it ends in two elegant, narrow fins that extend toward the rear and have a contour similar to that of the Coupé hard top. The fins make it possible to pull the material back tightly.

The top comprises an outer skin of a leakproof textile fabric. A headliner covers the frame, large portions of which are made of die-cast magnesium and aluminum. The soft top is entirely suitable for high-speed driving and acoustically very comfortable. When driving at 130 km/h (80.78 mph) with the top up, the wind noise level in the R8 Spyder are barely higher than in the Coupé, and at high speeds it is lower than in any of the competitor's cars.

The soft top has a straight electrohydraulic motor that is quieter and lighter than the electrohydraulics typically used. The pump mounted on the underbody of the R8 Spyder operates with a pressure of 120 bar.

A system of actuating cylinders, hinges and hooks opens and closes the top in 19 seconds, even while driving at speeds up to 50 km/h (31.07 mph). The procedure is initiated either by the key in the door lock or by the switch on the center tunnel. For reasons of safety, the button must be held when the vehicle is at rest, but a brief push of the button is all it takes to open the top at speeds of 6 km/h (3.73 mph) or above.

When opening the top, the windows first slide down, then the fins of the soft top turn upward. The large cover of the storage compartment, secured to two seven- link hinges, moves upward and in a curve to the rear. The soft top folds together in the shape of a Z and comes to rest as a three-layer, flat package in its compartment above the V10 engine. Finally, the cover closes again, first up front and then in the back.

The heated glass rear window, which is separate from the cloth top, is lowered into the bulkhead behind the seats. It can be raised and lowered via a separate switch, independent of the position of the top. When the soft top is open, it only rises 15 centimeters (5.91 in) – ideal for damping turbulence. It can also be nice to lower the window when the top is closed. When the sun is hot, lowering the window improves interior ventilation without causing unpleasant drafts.

A bag in the luggage compartment of the R8 Spyder contains a wind deflector with a solid frame. It can be snapped into its mountings on the bulkhead in just two steps. The wind deflector keeps the interior nearly free of drafts at speeds of up to around 200 km/h (124.27 mph).

Total safety: rollover protection

In addition to a large portion of the drive system for the top, two strong, spring- loaded aluminum sections that serve as rollover protection are also integrated into the bulkhead. The instant a belt tensioner or airbag deploys, magnetic switches release the interlocks and the sections shoot upward independently of one another within 0.20 seconds and catching rails lock them in place.

Head/thorax side bags in the backrests protect the passengers in the event of a side impact. Full-size airbags stand at the ready in the event of a head-on collision. In a rear-end collision, the integral Audi head restraint system reduces the risk of whiplash injuries.

The top with its drive system, the storage compartment, the cover and the rollover protection system forms a premounted assembly. It is installed in the vehicle during its craft-scale manufacture at Audi’s Neckarsulm site, where the R8 Spyder is built. The module gives the ASF body additional rigidity, thus contributing to the dynamic handling, the greater passive safety and the supreme vibrational comfort on board.

Ultra lightweight: the ASF body

The aluminum body of the R8 Spyder is top in its segment when it comes to lightweight quality – the relationship between weight, size and torsional rigidity. The body in white is comprised of three wrought components: Extruded aluminum sections comprise 75 percent; vacuum-cast nodes 8 percent; and the aluminum panels that are integrated into this skeleton with friction connections make up 17 percent. The panels are made of alloys that cure under heat - they attain their final hardness during the painting process, which includes drying in the oven.

Audi drew on its comprehensive expertise for the construction of the body. The ASF structure integrates a semi-supporting engine frame made of ultra lightweight magnesium. The floor tunnel is reinforced with custom, particularly lightweight tailored blanks.

The thickness of the individual panels varies as needed. They are joined by means of friction stir welding – a new method characterized by outstanding tightness, high dimensional accuracy and minimal distortion.

The body of the Spyder shares roughly 70 percent of its parts with the body of the Coupé. Critical areas – such as the center tunnel and the bulkhead – have been specially reinforced to be more rigid. The A and B-pillars and the sills have thicker sections; a crossbeam and aluminum plates that act as thrust plates are integrated into the central region of the floor. An aluminum panel is also attached to its underside, which further improves lateral rigidity. Additional sections in the doors serve as load paths in the event of a frontal collision.

Despite all of these reinforcements, the body tips the scales at a mere 216 kilograms (476.20 lb), just six kilograms (13.23 lb) more than the Coupé. Equipped with a manual transmission, the R8 Spyder 5.2 FSI quattro weighs only 1,720 kilograms (3,791.95 lb) and just five kilograms (11.02 lb) more in the R tronic version.

The side panels and the large cover of the top storage compartment also contribute to this positive value. They are made of carbon fiber composite produced using a new method. In addition to being faster and more energy- efficient than conventional production in an autoclave, resin transfer molding (RTM) also yields superior surface quality. Fiber-reinforced plastic is used for the engine compartment cover and the rear spoiler; thermoplastics are used for the bumpers.

Much of the body is lovingly built by hand at the Neckarsulm plant. The front end, the central floor and the rear end are assembled separately from one another. After they are joined to form the substructure, the pillars and the large metal panels – primarily the roof, the side walls, the doors and the cover panels – are added. Highly qualified employees make the weld seams, which total 107 meters (351.05 ft) in length. 814 self-piercing rivets and 188 automatically placed, self- tapping screws join the structural panels with the ASF skeleton.

The work is characterized by the utmost precision. A fully-automatic measuring system checks the dimensional accuracy of each body down to a tenth of a millimeter. The scanner works without contact and uses its 95 laser sensors to check 220 points within five seconds. The computer tomograph in which Audi performs random checks measures even more precisely. Its x-rays can detect deviations on the thousandths of a meter scale.

Design

The R8 Spyder 5.2 FSI quattro is 4.43 meters (14.53 ft) long, 1.90 meters (6.23 ft) wide and 1.24 meters (4.07 ft) high – it has a wide, hunkered-down stance on the road as if ready to pounce. The dynamic proportions, the sculputural design and the passenger cell situated far to the front with the flat windshield visually underscore the mid-engine concept.

As with every Audi, the single-frame grille is the distinguishing element – it is wide and low and painted in high-gloss black. Narrow chrome strips adorn the horizontal and vertical bars of the grille. The lip of the front skirt and the air inlets that direct air across the three radiators are also painted high-gloss black. The inlets have only two crossbars, which makes them look large and hungry.

An exclusive technological highlight is the standard LED headlights of the R8 Spyder 5.2 FSI quattro. Audi is the world's first automaker to use light-emitting diodes for the low beams, the high beams, the daytime running lights and the turn signals. With its color temperature of 6,000 Kelvin, the LED light is very similar to daylight, which keeps the eyes alert when driving at night. The excellent light distribution and long service life of the LEDs are additional advantages, plus they consume substantially less energy than conventional halogen lamps.

The headlights are technical works of art. Each of the daytime running lights comprise 24 LEDs arranged in a wave along the lower edge of the headlights that appear as a solid strip thanks to a plastic body placed in front of the LEDs. The headlight reflectors resemble open mussel shells.

Athletically sculpted: the air intakes

In contrast to the Coupé, the R8 Spyder is missing the sideblades in front of the rear wheels. Instead it has large vertical intakes that are athletically sculpted out of the flanks. The V10 breathes deeply through these intakes – theoretically 750 kilograms (1,653.47 lb) per hour each at full load. The doors have new trim strips with rising edges; the shadow contour of the rear end forms a stark, dynamic wave above the wheels.

Flared side sills set additional lighting accents and sculpt the flanks.

An elliptical crease encircles the long back and provides visual structure. When viewed from above, it combines the passenger compartment and the engine into a single unit. Two large cowls in shining silver discharge at the bulkhead. They taper as they extend to the rear and incorporate upright air openings. Another broad outlet is located between the cowls. It is open when the car is at rest and closed when driving so as not to disrupt the aerodynamics.

The airflow separates from the car very precisely at the slightly rising rear edge. The diffuser underbody sucks the R8 Spyder against the road when driving – downforce placed a greater role than drag during aerodynamic development. With a drag coefficient of 0.37 and the small front surface area of 1.99 m2 (21.42 sq ft), however, the high-performance sports car still glides smoothly through the wind. Audi applied a lot of the knowledge gleaned in motorsport to the flow of air around and through the body of the R8 Spyder.

The rear air intakes also have two crossbars. The exhaust system ends in two large, oval tailpipes, and the fully lined underbody ends in an upturned diffuser, which is painted black. The rear spoiler, modified somewhat from the Coupé, extends automatically at a speed of 100 km/h (62.14 mph). Its interior is designed such that when not deployed it dissipates heat from the exhaust region.

Numerous details demonstrate the love that the Audi designers poured into every detail of the R8 Spyder 5.2 FSI quattro. The windshield frame sports a shining application of anodized aluminum, into which the stainless steel brackets for the top are mounted for an appealing contrast. V10 badges on the flanks allude to the power of the engine. A black surface between the tail lights emphasizes the car’s width. Their chambers are colored dark red, with LEDs generating a three- dimensional light pattern.

Audi offers the R8 Spyder 5.2 FSI quattro with a choice of three colors – black, red and brown – for the top. The body is available in the solid finishes Ibis White and Brilliant Red; the metallic finishes Suzuka Gray, Teak Brown, Ice Silver, Jet Blue and Aurum Beige; and the pearl effect finishes Daytona Gray, Sepang Blue, Lava Gray and Phantom Black. Customers in search of more exclusivity can choose from roughly 100 special paint finishes or have their very own shade mixed.

Engine

Immense power, eager response and powerful acceleration, extraordinarily free- revving and a rousing sound – the R8 Spyder delivers a skin-tingling sports car experience. At idle and when coasting, its 5.2 liter V10 plays a characteristic Audi song – a throaty roar. Growling bass sounds and jubilant trumpets join in as engine speed increases, rising in concert to a crescendo, to a fortissimo.

The V10, which has a displacement of 5,204 cc, has the character of a racing engine. No wonder: With minimal modifications, the engine also powers the GT3 race car, which is based on the closed R8. Its peak torque of 530 Nm (390.91 lb-ft) is available at 6,500 rpm; rated engine speed is 8,000 rpm, where it produces 386 kW (525 hp). The electronic rev limiter does not intervene until 8,700 rpm, when the pistons travel 26.91 meters (88.29 ft) every second.

The ten-cylinder has a specific power output of 100.9 hp per liter displacement. Each hp only has to move 3.28 kilograms (7.23 lb) of weight. Equipped with a manual transmission, the open-top high-performance sports car from Audi tips the scales at only 1,720 kilograms (3,791.95 lb).

Performance is breathtaking. The Audi R8 Spyder 5.2 FSI quattro launches from a standing start to 100 km/h (62.14 mph) in 4.1 seconds. The version with the R tronic sequential transmission needs only an additional 8.3 seconds to break the 200 km/h (124.27 mph) mark. And the acceleration just keeps coming up to a top speed of 313 km/h (194.49 mph).

Ten cylinders: maximum dynamics

Ten cylinders are the ideal configuration for maximum dynamics. Compared to a V8 with the same displacement, a V10 has smaller and lighter pistons and connecting rods, allowing it to rev easier and higher. Compared to a V12, on the other hand, it has fewer components, which keeps the moving masses and thus internal friction low. The V10 is extremely compact – including all bolt-on parts, it measures only 646 millimeters (25.43 in) long, 737 millimeters (29.02 in) wide and 696 millimeters (27.40 in) tall.

Like nearly all V engines from Audi, the ten-cylinder – built by hand at the plant in Györ, Hungary – has a 90 degree cylinder angle. This wide opening results in a low center of gravity. The two opposing banks are offset by 18.5 millimeters (0.73 in). The bore measures 84.5 millimeters (3.33 in) and the stroke 92.8 millimeters (3.65 in).

The forged steel crankshaft is configured as a common pin shaft – each set of two opposing connecting rods engage the same crankpin. This design combines maximum rigidity with minimal weight, and ensures that the V10 alternately ignites in 54 and 90 degree intervals, which plays a major role in its goosebump- raising sound.

The crankcase is manufactured using low-pressure die casting, a complex method that ensures a particularly homogenous structure. Its aluminum-silicon alloy combines low weight with high strength. Its high silicon content makes the cylinder barrels extremely resistant to wear. The entire engine weights only 258 kilograms (568.79 lb).

The crankcase is configured as a bedplate construction: The lower bearing bridges for the crankshaft are integrated into a common frame for maximum rigidity and optimal vibration behavior. Because they are made of cast iron, they reduce the thermal expansion of the case and thus keep the clearance at the main crankshaft bearings within tight tolerances. The forged crankshaft and the connecting rods of forged steel also combine high strength with low weight. The pistons are forged of a high-strength aluminum alloy.

Oil supply like in motorsport: dry sump lubrication

The V10 features dry sump lubrication – a design that enables a low installation position and a corresponding vehicle center of gravity. The external tank and oil pump, which works with five different suction and discharge phases in the interest of efficiency, ensures lubrication under any conditions. The pump is designed for lateral accelerations of 2 g, as occur in motorsport. It draws the motor oil separately from the crank space, the chain box and the cylinder heads, and two coolers reduce oil temperatures.

The camshafts, as well as the oil pump, water pump and several auxiliaries, are powered by maintenance-free chains located on the rear wall of the engine. All four camshafts can be moved through 42 degrees of crankshaft rotation. This allows for a wide timing range for the 40 valves, which are actuated via roller cam followers. The exhaust valves are sodium-filled, which ensures a better cooling effect.

The V10 is managed by a sophisticated engine management system that operates with two computers in a master-slave configuration. Its direct fuel injection system operates according to the FSI principle developed by Audi. It is the ideal solution for the road and for motorsport, where it has long proved its superiority: The Audi R8 racing car won the 24 Hours of Le Mans race in four of five starts with FSI power.

A common rail system is responsible for distributing the mixture. It injects the fuel into the combustion chambers at up to 120 bar of pressure through nozzles located in the side of the cylinder head. The fuel mixture is swirled intensely and thus cools the walls. This enables a very high compression ratio of 12.5:1, which contributes to the high performance and very good efficiency. Mated to the R tronic, the ten-cylinder consumes an average of 13.9 liters of fuel per 100 km (16.92 US mpg). The 80 liter (21.13 US gallons) tank provides for a long cruising range.

The air induction path has been optimized for low losses. The intake manifold, which is made of a lightweight plastic, is characterized by its flow-optimized geometry. Tumble flaps controlled by the engine management system are integrated into the intake ports. At low load and engine speed, they cause the aspirated air to move with a roller-like motion (“tumble”), which further increases the efficiency of the combustion process.

On the exhaust side, a low backpressure and a sophisticated manifold ensures gas exchange with maximum dynamics. Two vacuum-controlled sound flaps in the exhaust pipe modulate the volume and timbre of the V10 as a function of load and engine speed.

Drivetrain

At only 215 millimeters (8.46 in) in diameter, the intermediate plate clutch in the R8 Spyder 5.2 FSI quattro is very compact, which is also necessitated by the low installation position of the engine. A six-speed manual transmission comes standard. The lever moves precisely and easily with short throws through a lavish, open stainless steel gate – typical Audi.

Audi also offers the R8 Spyder with an optional high-tech transmission – the sequential R tronic. With the short selector lever and the aluminum-look paddles on the steering wheel, it conveys an authentic racing feeling. Shift speeds vary as needed: The change of gears is comfortable during moderate driving; at higher engine loads and speeds, gear changes are completed within a tenth of a second. The driver’s commands are transmitted electrically. The gearshift unit has its own hydraulic fluid loop, which is pressurized to between 40 to 50 bar. The hydraulics manage the clutch and change the gears.

The R tronic is a versatile system, offering both a manual and a fully automatic operating mode. In both cases the driver can choose from two programs. The R tronic is most comfortable in the “Automatic Normal” mode, and offers the greatest dynamics in “Manual Sport” mode.

The standard launch control feature permits rocket-like starts. It is activated by a simple and exciting procedure: Select S mode, turn off the ASR anti-slip control, put the car in gear, step on the brake, floor the accelerator and wait until a constant engine speed is established. When the driver then releases the brakes, the launch control manages the engagement of the clutch within milliseconds, and the V10 delivers all of its power to the road with ideal tire slip. The Audi R8 is the only vehicle for which Audi offers this function with a manual transmission.

More grip: quattro permanent all-wheel drive

The extra bit of traction that allows the R8 Spyder 5.2 FSI quattro to pull away from its rivals is provided by the quattro permanent all-wheel drive – the superior technology for a high-performance sports car, in particular. Four powered wheels find more grip at the exit from a curve than two, enabling the driver to accelerate sooner again. Lateral dynamics and stability also benefit from quattro all-wheel drive. The R8 Spyder handles safely and reliably.

The mid-engine concept of the R8 model series necessitates a special layout for the quattro drivetrain. One drive shaft runs from the gearbox, which is mounted transversely behind the V10, through the engine to the front differential, where a viscous coupling distributes the power between the axles. In regular operation, it sends roughly 85 percent of the torque to the rear axle and can send up to 30 percent to the front within milliseconds, if necessary. A mechanical locking differential at the rear axle further improves traction. It provides a locking value of up to 25 percent when accelerating and up to 40 percent on the overrun.

Chassis

The mid-engine concept is the ideal solution for the Audi R8 Spyder 5.2 FSI quattro high-performance sports car. It enables an axle load distribution ratio of 43:57 between the front and back, and packs the engine in the middle of the car, close to the vertical axis. This nearly eliminates the inertia of the engine mass during fast changes of direction. The fuel tank is located close to the engine, in the crash-protected area behind the seats. The amount of fuel has hardly any effect on axle load distribution.

The R8 Spyder 5.2 FSI quattro is an integrated system of speed and highly concentrated emotions embedded in perfect technical expertise. The high- performance sports car from Audi turns spontaneously, almost immediately, into corners and handles them with stoic aplomb, precisely guided by its responsive steering.

The limit is extremely high and is very easy to manage, and all four wheels claw back into the asphalt at an early stage when exiting the curve. The quattro all- wheel drive literally meshes the car with the road.

Yet the chassis is surprisingly comfortable over long distances. The double triangular wishbones at all four wheels – a classic principle in motorsport – are forged aluminum to reduce the unsprung masses. Rubber-metal bearings dissipate lateral forces into the body with carefully defined precision, while at the same time ensuring good longitudinal elasticity and filtering a majority of the undesired vibrations away from the road. The track measures 1.64 meters (5.38 ft) up front and 1.60 meters (5.25 ft) in the back.

The hydraulic rack-and-pinion power steering with its highly differentiated, sensitive feedback makes a major contribution to the feeling of uncompromising precision when driving the vehicle. It features a sporty and direct 16.3:1 ratio. Audi fine-tuned the chassis and its setup over 9,000 test kilometers in the toughest laboratory in the world – the North Loop of the Nürburgring race track.

Sophisticated damping: Audi magnetic ride

The R8 Spyder 5.2 FSI quattro comes standard with another high-end feature – Audi magnetic ride continuously adapts the function of the chassis to the profile of the road and the driver’s style. The controller, which receives signals from a sophisticated system of sensors, continuously computes the optimal values for each individual wheel. When the R8 Spyder steers into a curve, the damping force on the outermost wheel is increased, which reduces the tendency of the body to roll and the reaction becomes even more spontaneous. The driver can choose between two base characteristics – normal mode and sport mode.

A synthetic hydrocarbon oil containing tiny magnetic particles between 3 and 10 thousandths of a millimeter in diameter – one tenth the thickness of a human hair – circulates in the shock absorber pistons.

When a current is applied to a coil, a magnetic field is generated in which the particles realign so as to be perpendicular to the flow of the oil in the piston channels and thus prevent it from flowing through. This process is completed in just a few milliseconds, much faster than with conventional adaptive damping.

The R8 Spyder 5.2 FSI quattro rolls on 19-inch, forged alloy wheels with an attractive 10-spoke Y design. The tires measure 235/35 up front and 295/30 in the back, and a control function monitors the tire pressure. The Audi exclusive line includes wheels of the same size featuring a five-twin-spoke design and a titanium gray or high-gloss, polished surface.

Incredible performance: the brakes

Extreme power necessitates uncompromising stopping power – the R8 Spyder has a powerful brake system on board. Eight-piston aluminum brake calipers are mounted up front, with four-piston calipers mounted in the back.

To dissipate the heat as quickly as possible, the discs are internally ventilated and perforated. The discs measure 365 millimeters (14.37 in) in diameter at the front and 356 millimeters (14.02 in) at the rear. Each disk comprises a steel friction ring and an aluminum cap; the two components are connected by stainless steel pins to prevent the transfer of temperature peaks.

Audi will mount an exclusive technology upon request – perforated ceramic brake discs painted Anthracite Gray. On duty up front are six-piston monoblock calipers of aluminum and 380 millimeter (14.96 in) discs, with floating calipers and 356 millimeter (14.02 in) discs in the back. The calipers are painted Anthracite Gray and are bear the lettering “Audi Ceramic.” The ceramic disks are extremely lightweight, together weighing nine kilograms (19.84 lb) less than their steel counterparts. They can also easily handle the loads of more aggressive driving and are always free of corrosion.

The base material for the ceramic discs is silicon carbide, an extremely hard, abrasion-resistant material with a diamond-like crystal structure. Embedded in it are high-strength carbon fibers that absorb stresses. The complex geometry of the cooling ducts ensures that heat is rapidly dissipated. The friction ring is bolted to the stainless steel cap via ten elastic elements.

The Audi R8 Spyder 5.2 FSI quattro brakes with aplomb – strongly, precisely and stably. A specially configured stabilization system monitors the vehicles dynamic driving limits. At the touch of a button, the driver can activate a sport mode that permits spectacular but safe oversteer when the gas is applied while exiting a curve. The ESP together with the anti-slip control can also be completely deactivated for dynamic driving situations such as a trip to the race track. The hill- start assist, a sub-function of the system, makes it easier to start off on grades by maintaining the brake pressure for a brief period after the brake pedal is released.

Interior, equipment and trim

The Audi R8 Spyder 5.2 FSI quattro is a sports car that is suitable for daily driving. The long 2.65-meter (8.69 ft) wheelbase and broad shoulder width of 1.39 meters (4.56 ft) allude to its generous spaciousness. Drivers and passengers of all sizes can find the idea seating position. Visibility is good, with narrow A-pillars ensuring a large diagonal view to the front. Another strength in daily use is the luggage compartment with room for 100 liters (3.53 cubic ft) under the hood. Mounted behind the seats is a three-bin storage box lighted with LEDs. One of the bins holds the optional CD changer or Audi Music Interface (AMI).

The interior dazzles with a markedly sporty yet comfortable character and is heavily driver-oriented. Its most distinctive element is the monoposto – the large arc encompasses the steering wheel and the cockpit before ending in the driver door and the center tunnel. The monoposto characterizes the dynamic style of the interior every bit as much as the multifunction steering wheel with the ring flattened at the bottom.

The controls are clearly structured, with the controls of the deluxe automatic air conditioners specially matched to the needs of open-top driving. Important information is displayed on a color monitor. The standard driver information system displays the speed digitally and includes a lap timer function for recording lap time. Red rings frame the instruments and the solid aluminum gear lever knob. The pedals, the footrests and the shift paddles of the R tronic are in aluminum look.

The fit and finish of the R8 Spyder 5.2 FSI quattro is of unmatched quality – typical Audi. The surfaces of the instrument panel and door liners are backed with a soft material and the decorative stitching is extremely precise. Most of the interior is a sportily cool black; the decorative inlays shine with a satin finish and the aluminum applications adorn the door sill strips. Small LED lamps bath the interior in subtle light, if desired. Many of the components in the interior, such as the top sills and the instrument panel cover – are covered in leather.

Numerous customization solutions are available. Audi offers Alcantara and leather upholstery in a wide variety of colors and grades, packages in carbon and black piano lacquer or a tailor-made set of suitcases. Elegant design and leather packages set additional individual accents.

All inclusive: standard equipment

The Audi R8 Spyder 5.2 FSI quattro will go on sale in Germany in the next few days with a long list of standard equipment at a base price of 156,400 euros. This includes power folding side mirrors, a light and rain sensor, LED headlights, an alarm system and a Bang & Olufsen sound system. It pumps out 465 watts and dazzles with excellent sound from 12 speakers. The systems mid-level bass and high frequency ranges have been specially matched to the acoustics in the R8 Spyder.

Also included standard is the navigation plus system with MMI control logic featuring impressively high resolution and fast route calculation. It reads the route data from a DVD and presents it as a three dimensional graphic on the 6.5-inch monitor.

The seats including the lumbar support are power adjustable and heated. Their Fine Nappa leather coverings are specially pigmented to reflect the infrared rays in sunlight and thus protect the interior from heating up. Audi offers a choice of the colors black, titanium gray, lunar silver, nougat brown, luxor beige and red.

A worldwide first from Audi is the seatbelt microphone for the hands-free unit, which makes it possible to talk on the phone even with the top down on the highway. Integrated into each of the two belts are three microphones that resemble small, flat discs and do not interfere with the rolling up of the belts. When the seatbelt is being worn, one microphone is always located in the vicinity of the mouth, regardless of the person’s height. Software analyzes the quality of the signals and forwards the best one to the hands-free unit. A fourth microphone is mounted on the windshield frame and is used to make calls when the car is parked and the seatbelt is not on.

The range of optional equipment offers additional attractive features, including the Audi parking system advanced with integrated rearview camera, the high- beam assistant, a storage package or Bluetooth mobile phone preparation. A sports suspension with conventional dampers is available at no charge to sharpen the racing character. The front spoiler, the rear diffuser, the mirror housings and several engine compartment components are optionally available in carbon from Audi.

quattro GmbH, which developed and builds the R8 Spyder 5.2 FSI quattro, will also fulfill more extravagant wishes.

Power like a big V6, fuel economy like a modest four-cylinder unit – Audi presents the A8 hybrid as a technology concept at the Geneva Motor Show. Its two propulsion units – a 2.0 TFSI and an electric motor – develop a total output of 180 kW (245 hp) of system power and 480 Nm (354.03 lb-ft) of torque. This enables the Audi A8 hybrid to accelerate in 7.6 seconds from zero to 100 km/h (62.14 mph) and to achieve a top speed of 235 km/h (146.02 mph). Yet its average fuel consumption amounts to only 6.2 liters (37.94 US mpg) per 100 km – the CO2 equivalent is 144 grams per km (231.75 g/mile).

The technology of the Audi A8 hybrid

The combustion engine of the Audi A8 hybrid is the 2.0 TFSI – a high-tech powerplant. This four-cylinder unit, which has been named "Engine of the Year" five times in a row since 2005, is an example of Audi's downsizing philosophy. It combines direct fuel injection with turbocharging and the AVS Audi valvelift system, which regulates the valve lift in two stages. In combination with the adjustable intake camshaft, the Audi valvelift system improves cylinder charging and ensures spontaneous and powerful torque build-up. The 2.0 TFSI delivers 155 kW (211 hp) and 350 Nm (258.15 lb-ft); the torque value remains constant from 1,500 to 4,200 rpm.

In the crankcase of the four-cylinder unit, which has a displacement of 1,984 cc, two balancer shafts offset second-order inertial forces to ensure virtually vibration-free and pleasantly quiet operation that goes well with the luxurious character of the A8. All components are optimized to minimize friction. The flow-rate-regulated, pressure-controlled oil pump further reduces fuel consumption.

Electric motor with ample propulsive power

A hydraulically operated wet clutch links the 2.0 TFSI with the electric motor. Its control requires the utmost precision, and a great deal of know-how has been expended to achieve its smooth, precise and swift operation. The synchronous motor, which is continually excited, also serves as a generator that develops 33 kW (45 hp) of power and 211 Nm (155.63 lb-ft) of torque. Its full power is available practically right from standstill and contributes to a sportily powerful start-up. Since an electric motor also develops heat, its housing is furnished with cooling ducts. Interposed between the electric motor and the wheelset of the eight-speed tiptronic, which is controlled entirely by electronics, is an additional cut-out clutch. In conjunction with the electric unit, this functions as a torque converter. The propulsive power of both drive systems is applied to the road through the front wheels.

Lithium-ion technology – the battery

The energy storage system of the Audi A8 hybrid is mounted in the rear section. This state-of-the-art lithium-ion battery is more compact and weighs less than other types but is substantially more powerful. It is protected by a high-strength housing, and a ventilation module ensures that it always operated within the ideal temperature range. Yet the A8 hybrid also provides ample luggage space of 400 liters (14.13 cubic feet).

Several subsystems that operate on engine power in a conventional car have been modified right from the start for use in the Audi A8 hybrid. The compressor in the climate control system runs entirely on electric power. The steering system is electromechanical as well. The brake booster too is supplied by a demand-controlled electric vacuum pump. During electrical – i.e. recuperative – braking actions, a sophisticated control system ensures that the ABS and ESP functions operate properly.

The power electronics unit manages the interaction of the systems. Its pulse control inverter regulates the interplay of the battery and the electric motor. The DC-DC converter supplies power to users on the onboard network. The power electronics unit, which is connected to the battery and the electric motor by high-voltage cables, is located in the engine compartment.

The smooth interaction of these components and their high level of integration attest to the specialized know-how Audi has accumulated. The technology architecture already provides a glimpse of a future production model – the Audi Q5 hybrid, which will be introduced later this year.

Driving experience

The Audi A8 hybrid, which weighs 1,885 kilograms (4,155.71 lb), drives as if it had a big six-cylinder gasoline engine or a TDI under its hood. From zero to 100 km/h (62.14 mph) the vehicle accelerates in 7.6 seconds, and it can continue to accelerate up to 235 km/h (146.02 mph). Yet its fuel consumption according to the EU cycle is only 6.2 liters per 100 km (37.94 mpg), corresponding to 144 grams CO2/km (231.75 g/mile). In city traffic, the hybrid drive uses about 20 percent less fuel than a conventional drive. Both the car's performance and its fuel economy benefit substantially from a major advantage of the A8 model series – its lightweight aluminum body based on the Audi Space Frame principle (ASF).

The hybrid drive is designed for fully electric-powered driving up to 65 km/h (40.39 mph) and for a distance exceeding two kilometers – especially well-suited for driving in the city or residential suburbs. When conditions permit, the driver can also select the electric mode by actuating a separate e-key in the cockpit. Both the display screen of the instrument cluster and the large monitor of the MMI operating system on the dashboard present all momentary power flows in brilliant graphics.

When the Audi A8 hybrid starts moving, both of its engines interoperate closely to suit varying power demands. Above 65 km/h (40.39 mph) the combustion engine alone does all the propulsive work, while the electric motor supplies onboard users and recharges the battery.

When the driver lets up on the gas, the combustion engine is disconnected from the drivetrain, so the Audi A8 hybrid "sails". In braking and slow-down phases, the e-motor functions as a generator – recuperating energy efficiently and feeding it into the battery.

When the driver floors the pedal, the engine management temporarily controls the entire system power, and now the electric motor is boosting power. 180 kW (245 hp) and 480 Nm (354.03 lb-ft) endow the big sedan with enormous thrust. The intermediate sprint from 60 to 120 km/h (37.28 to 74.56 mph) in fifth gear for instance is accomplished in 7.5 seconds. The Audi A8 hybrid is an extremely dynamic car – with a fuel efficiency that is setting new standards. This is especially true in everyday user activities. Even its looks betray the power of this near-production concept car with its big 21-inch wheels and their 265/35 tires. Efficiency and sportiness are no paradox at Audi – they go hand in hand.

The design of the Audi A8 hybrid

This near-production concept car has 21-inch, two-colour wheel rims styled with highly three-dimensional surface areas. The exterior paint job of the A8 hybrid is in "Prism Silver" with "Spectra Flair" as an accent color – a rainbow effect that's accentuated in reflected light along creases and seams on the body. The prominently located "hybrid" lettering on both front fenders leaves no doubt about what kind of car this is. The accentuation of its width by a prominent low horizontal spoiler edge and a chrome strip conveys the vehicle's solid stance on the road.

The engine compartment cover with its high-gloss finish and the glass cover of the battery in the trunk also provide visual links to hybrid technology. And the illuminated doorsteps bear the "hybrid" insignia as an elegant touch to underscore the electric aspect whenever the doors are opened – using LED technology to minimize energy consumption.

The passengers also see the prominent hybrid logo displayed on the dashboard. The "Powermeter" in addition shows the energy flow in the instrument cluster.

Audi is presenting a new vehicle concept – the Audi A5 Sportback. The five-door model with the long, flowing rear end unites the best of various vehicle genres: the emotion and elegance of a coupe, the comfort of a sedan and the practicality of a station wagon. The Sportback joins the Coupé and Cabriolet as the third member of the A5 model family.

The A5 Sportback will be rolling into Audi dealerships in September featuring an emotion-packed design, high everyday practicality, a sporty character and engines that are as efficient as they are powerful. Sales have already begun, with prices starting at 33,650 euros. A further, specially-priced model to follow in 2010 will make the A5 Sportback the entry-level model in the A5 model series.

Audi, the inventor of the Avant, is setting new trends in design with the A5 Sportback. The five-door coupe is defined by elegant lines. It is 36 millimeters (1.42 in) lower than the A4 Sedan; with its short front overhang, long wheelbase, wide track and the four frameless doors with their slender window lines, it is the very picture of sporty elegance.

The interior is spacious, offering uncompromising comfort in all four seats. The large luggage compartment hatch is harmoniously integrated into the long, tapered tail end with the flat C pillars; the spoiler lip underscores the tension-filled character. The luggage compartment volume of 480 liters (16.95 cu ft) nearly matches that of the A4 Avant and increases to 980 liters (34.61 cu ft) with the rear seats folded down.

The A5 Sportback follows the consistent path of innovative technologies at Audi when it comes to the drivetrain. All of the engines are highly-efficient direct injection models – TDI for the cultivated diesels, FSI for the gasoline engines – and all comply with the Euro 5 emissions standard.

All models are equipped with a recuperation system that recovers energy during braking and deceleration and stores it temporarily in the battery.

Audi is initially offering three gasoline and three TDI engines, with three more engines to follow by mid-2010. The gasoline engines – the two-liter TFSI with 132 kW (180 hp) or 155 kW (211 hp) and the 3.2-liter V6 with 195 kW (265 hp) – are equipped with the Audi valvelift system for variable control of valvelift. The intelligent technology boosts performance while simultaneously reducing fuel consumption.

The 2.0 TDI produces 125 kW (170 hp) and consumes on average a frugal 5.2 liters of fuel per 100 km (45.23 US mpg). It is coupled with the start-stop system, which further enhances fuel efficiency in city traffic. The 140 kW (190 hp) 2.7-liter TDI offers even more power. The 3.0 TDI, which also features the S tronic, puts out an impressive 176 kW (240 hp).

Like the three gasoline engines, the top diesel engine delivers its power to the quattro permanent all-wheel drive system. The two most powerful engines are optionally available with the newly developed sport differential, which variably distributes power between the rear wheels and provides even greater dynamics, driving pleasure and safety. The two TDI models with front-wheel drive – the 2.0 TDI and 2.7 TDI – and the 2.0 TFSI (132 kW / 180 hp) benefit from another Audi innovation: The ESP stabilization program with electronic front differential lock increases agility and prevents understeer.

The perfect complement is the Audi drive select vehicle dynamics system, which enables the driver to freely vary the throttle response characteristic, the shifting points of the seven-speed S tronic, and the boost provided by the servotronic steering system, which comes standard (from power outputs of 140 kW (190 hp) upwards). The system is offered as a modular package with at least one of the following three options: sport differential, adaptive shock absorber control or dynamic steering with variable boost.
