With DCT the M3 is on par in straight line speed with a stock C63 all the way to VMAX - and not from magazine times but from personal experience on the autobahn a few weeks ago.......there was nothing in it at all in it.
Of course the C63 can be tuned very cheaply and then we are talking a different outcome - if straight line speed is your main priority.
