I'd have to go with a twin turbo version of the next gen turbo I6. Put this in a lighter chassis, which they will since the CFRP will be more readily available for body panel switches going from F3x to the M3. I can't even imagine a V6- absolute BMW sacrilege.

Luxury goodies won't be going anywhere since so many want them. Ad long as the brunt of them are optional, what's the issue? Weight has creeped upwards for safety and features and size. I believe we are witnessing the plateau and next the reduction as lightweight technologies improve and costs associated with them decrease.

Also, for an M-specific engine, they could bore it out a bit for more displacement. We know the mass produced engines will be in 0.5L cylinders, but M could and should be able to modify that for their purposes.

Let's just hope the feeling full hydraulic steering rack makes it into the next M3....
