The current turbocharged V6 and V8 gasoline engines being used by Porsche and Audi may be due for a replacement as AutoCar UK recently reported that the two companies entered a joint engineering program to develop a new line of 90-degree V6 and V8 powerplants.
Both the 6-cylinder and 8-cylinder engines will reportedly gain a 500cc increase in each cylinder, which will result in a 3.0-liter capacity for the V6 and a 4.0-liter capacity for the V8.
The rumored engines will also be scalable, which means that a smaller version of the powerplant may also be available. Nothing is solid yet though the smaller V6 is expected to displace 2.5-liters and may use Atkinson-cycle technology.
Forced induction will be provided by new gas-driven turbochargers in the first stage of production though insiders have stated that the two companies plan to introduce electric turbochargers in the future.
Internally, the new engines are codenamed KoVoMo, a play of words on the German words ‘Konzern Vee Otto Motoren’ (Group Vee Gasoline Engines). If completed, the engines may also power future models under Volkswagen AG besides the original developers including: Bentley, Volkswagen and Lamborghini.
