If BMW had released the F10 M5 weighing 300lbs less that the E60, with an extra 100lbs ft but still "only" 500hp. I doubt there would be many haters.
The 1 M surprised us all, it wins a hell of a lot of comparisons against some pretty damn good cars. With these specs it's likely that it will basically be in the weight range of a 1 M with an "American" driver, 420hp and 400ft lbs of torque, a stiffer chassis and M-DCT. Speed won't be a problem.
Just look at the engine bay strut braces and the super flat cornering in the ring videos... I think the ace up the new m3's sleeve will be its handling dynamics, which is what it is supposed to be about. If you want to drag race people, wrong brand.
