CARandDRIVER reports that Audi will be dropping two cylinders for its next generation RS4 to stay in close battle with the BMW M3 sedan. The Audi RS4 has always been powered by Audi’s beloved and luscious 4.2L naturally-aspirated V8, with the exception of the first generation 2.7L twin-turbocharged V6 powered 2000 RS4 Avant. The current model’s mill is even good for a lovely 450hp and 417 lb-ft of torque.
The new and current BMW M3 utilizes BMW M’s first ever TwinPower Turbo inline-six, which is good for 431hp and 406 lb-ft of torque. That said, to make sure the Audi RS4 matches up on paper, rumors point to the use of a twin-turbocharged V6 for the new RS4. A supercharged V6 isn’t too far-fetched either as Audi currently offers one throughout the range as the base engine. It could be used as a starting point.
Either way, it will be sad to see Audi’s beloved naturally-aspirated V8 begin to disappear as the demand for fuel economy causes everyone to downsize their engines.
