so if the motor is just as powerful stock, how is it not going to take away sales from the m3 just as the n54 did?
Factually incorrect? Tri-turbo, just like whether or not the engine will be a straight 6 of v6, its all speculation. As of right now, there really are NO facts -- For all we know the next M3 coupe might be rebranded the M4 (I hope to God that it won't be).
I also never said it was going to be an N54, my comparison was that it would be a bit foolish for BMW to have to two (one in the 335i & one in the next M3) twin-turbo'd six cylinder engines in the same model range.
