Just read an article about some interesting innovations used in the 335i that insure as much of the engines power gets to the drivetrain as possible. I sure hope these (or more/better) are included in the M3. It sounds like there is quite a few hp to be had through these techniques.
- Electric water pump (not belt driven)
- Variable flow oil pump
- Magnetic A/C clutch that fully disengages when not in use
- Intelligent alternator that charges only when coasting/braking
