If the C63 used the same 4.0 motor the M3 does it would need to be built also to make 750+ HP. The two platforms are very different. Much easier to make that level of power with a 6.3. We have two C63 AMG cars one is a black series and they can make very high power with the stock motor. Very impressive cars with boost.
