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.
The amount of torque you make after 5252 rpm is irrelevant. there's nothing gained by making a higher percentage of peak torque at redline.
