If that is not good enough for you WTF is?
An engine consists of a block, with pistons and rods, and a head. All the magic happens in the head and induction system. Yes the M3 might share the bottom end of a more mundane 3 series (sic.), but it does have a unique to M3 head and induction system. That's all that matters.
Sorry, but I'm just not as impressed by what amounts to a tune of a turbo engine as I am a NA engine from M's past, and the purpose built engine of the e9x series. I am sure the F series engine will be great, but I feel like I've essentially already seen it in the form of N54/55. Great, just not that special for an M car.
As for the F1 engine, yes it's impressive, but that's not the kind of engineering going into the F series engines thus far.
