Audi wants to offer a successor of the ice-cold cool Q7 V12 TDI according to a new report.
Dr Ulrich Hackenberg, Audi’s head of technical development told English car magazine Autoexpress that a faster SQ7 model is in the works, powered by a twin-turbocharged V8 diesel engine which uses a pair of electric turbos in order to wipe out the lag forever and ever.
The technology was first shown on the Audi RS5 TDI-e Concept, and uses “e-boost” electric motors to spin the turbos before the exhaust gases get in there. With this solution the turbochargers will offer their benefits without the usual lag in throttle response and Audi says that even a diesel will offer a sharp response. The electric motors spin the turbos up to 3,000rpm and then leave the exhaust gases on their own completely to continue compressing the air into the induction.
The same report says that the engine will be based on the 4.2-litre TDI unit used in the Cayenne Diesel S and might have a slightly smaller capacity. The engine is also going to be used in the Bentley Bentayga which is based on the same MLB-evo platform the Q7 uses. The power is expected to reach over 400hp with a torque figure to match its super-diesel credentials and be able to move the earth.
