Volvo has revealed its new Drive-E powertrain concept, which is a 2.0-liter four-cylinder engine that generates an awesome 450 horsepower. The engine is a follow up to the Drive-E engines that Volvo launched in 2013 and showcases how Volvo intends to downsize its engines, without sacrificing performance.
The Drive-E Powertrain Concept 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. Volvo says that With this kind of power density, the triple boost installation and unique fuel system, there shouldn’t be any turbo lag.

“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.
As of right now Volvo has not announced if the 450-hp engine will enter production.
