Where the heck are your dyno charts showing 460+hp @ the wheels? You have nothing to back up your statement.

You have the best data available the 335i / M5 / RS5 run on the same dyno. 335i showing 6%, M5 7% and RS4 17%. As I wrote, forgetting the absolute values, please try to explain what there is only 1% difference between drivetrain losses on the 335i and M5?
