The engine for the M3/M4 is probably still under development and or testing. The engine specs for the regular 4 series concept we've seen have yet to be released, and sound like they won't be released until this coming Spring. I wouldn't expect to hear about the engine specs of the M3/M4 until after we see them in concept form.
