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?
tri turbo is what I've heard as well. It's also rumored to be rated at 450 hp, but since it's a turbo we should be able to tune the bejesus out of it! It won't be an "N" designated motor...it'll likely be an "S" designation...the 1M was the aberration. F80 M3 is in fact the chassis designation for the new M3 as I've seen it written (I had to look twice at this too!)
