Audi RS4.
4.2L 450HP, 8000+ rpm
Last powerful NA engine from Audi??
Kinda funny. Audi went for NA in a big heavy 4WD car where steering feeling is not that great...
BMW who has been more dedicated for NA, straigth six, RWD only, steering feel and mostly petrol engines have focues max on turbo and "watered down" their core principles lately. I think they are doing the right thing on focusing on turbo engines in these days tough. As long as lag is minimized!
Im guessing turbo will be even more normal in the near future. After owning a 2010 Cooper S, I really start to like torque and power from down low combined with great fuel economy and a "minimum" of lag.
Even Toyota will start focusing more on turbo technology.

8000+ RPM in a angry NA is still the best car porn tough!
