If the horsepower and torque figures we've been hearing turn out to be correct, then this motor will be losing power quickly as you approach redline (like the current N54/N55 but I expect an M motor to have a better power curve). If you compare that to the power curves for the current S63tü, it makes almost 80% of its peak torque at redline while these rumored power figures would mean the S55 in the new M3 will barely make 70% of peak torque at redline so I still believe the real horsepower figure will be higher than 420, despite the rumors. We'll see.

I hope your right on the horsepower. Common M, lets see 450 HP / 400 lb-ft AND nearly an 8K rpm's!!
I'm still drooling on the new C7 Stingray...
