Maybe... Maybe not. Check the "regular" 2012 C63 'Ring time compared to the e92 M3 and report back (hint, it is faster by 4 seconds). You aren't giving the revised C63 credit for its handling and braking. Both of which are very close to the M3 but the almost 100hp advantage of the 507 will more than make up the difference.
Having said that, times only mean so much as the M3 is still the better overall track car IMO but you are nuts to think the 507 won't be faster on most tracks. The only tracks where the M3 will be as fast IMO are very short, very tight tracks and, even then, maybe not.
