Forged crank is a big plus for the 54 also.
Has it been confirmed that the 55 will reside in the new M3? I seem to recall many here were dead set sure that the 1M would certainly have the N55 under the hood and posted right here in this forum. They were using up all the antiquated 54's in the 335is model to 'get rid of them' but would never use the in the M and yet here they are.
BMW evolved the N55 to be a 'greener' power plant. Less pollution and better mileage were the goals.
