Volvo recently unveiled the High Performance Drive-E Powertrain Concept, a triple boost 2-liter 4-cylinder petrol engine with no less than 450 hp.
The 450 hp High Performance Drive-E Powertrain Concept is based on a set of technologies not usually found in a four cylinder engine, the company said in a statement.
The engine utilizes two parallel turbochargers, which are fed by an electrically powered turbo-compressor. The compressed air from this unit, rather than being fed to the cylinders, is instead used to spool up the two parallel turbochargers.
Fuel is fed by a dual fuel pump working at 250 bar pressure. With this kind of power density, this triple boost installation and unique fuel system, enables a very dynamic drivability without any turbo lag, compared to a mono-turbo, Volvo said.
“When we launched the Drive-E powertrain family, our aim was to deliver the most advanced 4-cylinder engines in the industry based on emissions and fuel consumption relative to performance and drivability. We knew that 320 hp in our petrol configuration was just a starting point. The 450 hp High Performance Drive-E Powertrain Concept, demonstrates this ambition and the versatility of the Drive-E Powertrains,” stated Dr. Peter Mertens, senior vice president for research and development at Volvo Car Group.
