Porsche’s new 2007 911 GT3 will make its public debut at the Geneva Motor Show on February 28, 2006. The latest race-bred 911 sports coupe features a 415-horsepower naturally aspirated engine with an 8,400 rpm redline, an active suspension setup tuned for the track, and a mechanical limited-slip differential.
In the 911 model range, the GT3 provides uncompromising dynamics that let this street-legal machine
easily make the transition to the racetrack. The 415-horsepower, 3.6-liter flat-Six engine produces a specific
output of 115.3 horsepower-per-liter, among the highest of any naturally aspirated production car. The Boxer
engine’s power peak is reached at 7,600 rpm, on the way to an 8,400 rpm redline — 200 rpm beyond the
previous GT3 model.
In addition to its high-revving characteristics, the GT3 engine’s performance has been fortified by careful
attention to airflow rates. Changes to the variable intake system include a throttle valve enlarged from 76 to 82
millimeters, optimized cylinder heads, and a low-backpressure exhaust system.
To take advantage of the extended-rev characteristics of the engine, the 2007 911 GT3 features a
revised six-speed manual transmission, with lower gear ratios for 2nd through 6th, as well as shortened shiftlever
throws. A new change-up display, which illuminates the tachometer shortly before the relevant engine
speed is reached, provides GT3 pilots with an additional signal to optimize shift timing.
The combination of a more powerful, higher-revving engine and shortened gear ratios produces
impressive acceleration figures, allowing the 2007 911 GT3 to reach 62 mph (100 km/h) from a standstill in
4.3 seconds, and 100 mph (160 km/h) from a standing start in 8.7 seconds. The top test-track speed of the
new 911 GT3 is 192 mph (310 km/h).
For the first time, the 911 GT3 boasts an active suspension. The standard Porsche Active Suspension
Management (PASM) system offers two chassis in one: the basic configuration is similar to that of the previous
model and is suitable for driving on alternating road surfaces. In Sport mode, the system provides even firmer
damping, enabling more focused dynamics for the racetrack.

For the best possible transmission of engine power to the road, the GT3 is equipped with a
comprehensive traction package, including new electronic Traction Control adapted from the Carrera GT,
standard-equipment 19-inch sports tires, and a mechanical limited-slip differential. The new Traction Control
setup features traction-slip and drag-torque control functions, allows safe traction under any driving conditions,
and can be completely disabled if desired.
The 2007 Porsche 911 GT3 will be available in North America beginning in August 2006. U.S. pricing for the
new model is $106,000.
