No shock there. We all know the M3 is a more well balanced road course designed car. However 99.9% of M3 owners drive their cars on public roads so how much does this really matter? Just to add a little information to the forum, the P31 C63 which are allegedly rated at 481 BHP are putting down 420 RWHP on a Dyno Jet. Sounds like MB is doing a W211 E55 job here. They claimed 469BHP but all stock E55's were putting down 420+WHP on a Dyno Jet.
