Volvo surpasses Mercedes Benz AMG with 450 Bhp, 4 Cylinder Drive E triple turbo petrol engine

Volvo surpasses Mercedes Benz AMG with 450 Bhp, 4 Cylinder Drive E turbo petrol engine

When Mercedes Benz launched the A-Class A45 AMG high-performance hatchback, it staked claim for the most powerful, 4 cylinder petrol engined production car, with 360 Bhp-450 Nm outputs from its 2 liter-4 cylinder turbo petrol engine. Now though, AMG will have to make major revisions to this engine if it intends to retain the title of being the maker of the world’s most powerful, production 4 cylinder petrol engine as Volvo is all set to usurp that title.

Volvo has unleashed a new, 2 liter triple turbocharged petrol engine that makes an astounding 450 Bhp of peak power. Peak torque figures are yet to be released. This said, expect the peak torque figure of the Volvo Drive E engine  to be higher than Mercedes Benz’s 450 Nm output for the 2 liter turbo petrol engine that is used in the likes of the A 45 AMG, CLA 45 AMG and the GLA 45 AMG cars, given the significant power advantage it has over the Mercedes Benz AMG engine.

In the 2 liter-4 cylinder, Drive E turbo petrol engine, Volvo has employed twin turbochargers in parallel, that get additional boost by means of an electric turbo compressor. The electric turbo compressor directly spools the twin turbochargers instead of feeding air into the air intake, as is the case with conventional turbochargers. By employing the electric turbo compressor in tandem with the twin turbochargers, Volvo claims to eliminated turbo lag, to make for linear power delivery.

Other advantages of the triple turbo layout include a lighter engine that sits lower in the car to make for a lower center of gravity and consequently better handling. The triple turbo, 2 liter petrol engine is likely to find application in a range of cars, from the V40 Polestar hatchback to the flagship, 2015 XC90 SUV. Volvo hasn’t revealed the exact timeline for the introduction of the triple turbo, 2 liter Drive E petrol engine though.
