I just read in road and track the new M3 will have the same engine as the european version with about 340 horses, it also said that they wont put in the 8 cylinder. But 340 in the two door m3 sounds pretty good to me. In addition they are currently not making any more four door M3's. If your looking four doors you can look into the M5 with 400hp but with a price tag of about 90k
