As for the power differences between the F22 M2 and the E82 1M, there are perhaps two things to consider. First, the 1M was a limited production car that only existed for one MY during the E82's life cycle, so it might not be considered a direct predecessor to the M2 by the folks at BMW. Or at least, they would use that reasoning as the excuse for why a slight power dip by the M2 might be acceptable. Second, these figures that we're quoting are all just targets and rumors. Even Scott26 himself has said that things may change. So for all we know, the F22 M2 might get an ultra-juiced version of the N20 that will produce equal or greater power than the 1M. Or, as you state, the gap between the M235 and M2 might be too narrow to establish a clear market segment, and BMW might nix one of them (as they recently did with the X1 M35i and the X3M).
Time will tell
For sure. Guess we'll have to wait and see!
