E60 M5: 101 (probably more like 106 based on actual performance, engine is widely regarded as underrated)
F430: 112
RS4: 101
GT3: 115
And just for comparison purposes (not really fair since only 1 liter and much easier to get massive revs: redline = 13,500)
Yamaha R1 sportbike: 180 hp/l
If the displacement stays at exactly 4.0 liters, BMW offersno advancesto the M5 heart of the new engine AND the redline stays at 8k even we can count on 404 - 424 hp. I doubt output is the problem, if any.

That depends on the fact how many HP BMW wants from the V8, I agree 424 isn`t the problem, they could produce easaly that amount off HP.
I think the problem is the fact that BMW wants 440-450 HP from the 4.0 V8, there is where the challenge is for the new M3. Make the best engine world wide, set a new, verry high, standard for NA engines and leave competitors like the Audi RS4 ( too my best knowledge has a 4.2 Liter engine) way behind
