Wow, the BMW marketing guys really got you hooked. I don't think there's such thing as a car with less than 10% drivetrain loss. Mabe a Prius or Civic Hybrid???
So you say.
If you look at the numbers for the 335i, it is showing 6% loss. Either the 335i is "underrated" or BMW have made some innovations on the efficiency....which will carry over to the M3 (which is what this thread all about).
