450 hp Volvo High Performance Drive-E Powertrain Concept

Volvo High Performance Drive-E PowertrainVolvo delivers a unique combination of performance and efficiency with the Volvo High Performance Drive-E Powertrain Concept – a triple boost 2-liter 4-cylinder petrol engine with no less than 450 hp.

The 450 hp Volvo High Performance Drive-E Powertrain Concept is based on a set of technologies not usually found in a four cylinder engine. 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.

“There are several high power small size applications where one large turbo is used to create a high level of power available from other manufacturers, but the driving experience suffers due to slow engine response. We felt that with our heritage of being among the first car companies to embrace and offer a broad range of turbo technology since 1981, that we could improve this,” says Michael Fleiss, Vice President of Powertrain Engineering at Volvo Car Group.

The Volvo High Performance Drive-E Powertrain Concept attracted the attention and involvement of Volvo Cars suppliers AVL, Denso and Volvo Polestar Racing at an early stage, which allowed theories and technologies from racing applications to be infused in the development process.

“This was a very exciting project as we pioneered a combination of technologies in the same application, and the result is a quite unique engine with its high power yet quick response. Above all, its compact size improves weight distribution between the front and rear axle and lowers the center of gravity – two factors that have a significant effect on the handling, whether it is a race car or a street car,” said Mattias Evensson, Race Engine Director at Volvo Polestar Racing.
