Both engines have been developed ... in the moment the cheaper 3.2ltr.I6 is favored (here is Scott right!) but BMW/M-GmbH could also change this descission until the M3 specs were fixed.
So it is really a 3.2l I6? Is it then a bored or strked N54/N55? I wonder what is the purpose of it. Or could it be M GmbH is working on replumbing and turbocharging the old S54? That would be something interesting. If not I still continue hope they chose back the V6.
