Bmw will be calling all new M3 coupe M4. M3 coupe will be designated to the sedan models. Heres a few spy shots of the new M4. Rumors to be realized as 2014 model year. Its also suppose to have inline six with twin turbo chargers. Suppose to be lighter and faster the the previous V8 M3 models. I personally think M3s (or M4 for that matter) Should remain true to high reving natural aspirated motors. But I guess with current market demands the change. Will have to see if this new Ms will carry the M dna.
