Thanks for the explanation in PM.
I don't think BMW will use different engines for sedan and coupe M3/M4.
I need 4 doors in my M3. So I'll be pissed off if the 2-door version would feature a different/better engine. But I could live with the idea that the car setup of the coupe is somewhat sportier/extremer than the sedan. (like with the previous generation M5 and M6 - 5L V10)
Also: developing, testing, producing, crash-testing, bulk-manufacturing an engine just for the relatively limited number of 'M3 sedans' doesn't make any economical sense.
