Ironically this thread just started on the M5board....RS4 sucks balls for drivetrain losses (17%). BMWs are pretty good (7%). Wait til the Supercar Shootout in Sweden vids come out....the Audi's out pwn'ed by almost every car.
Here is the link for the 335i....even better than the M5 at 6% loss (but I suspect this goes up with more power)
