- 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
the impression I got is that this will be the already existing M5 engine, just cut off the last extra 2-cyclinders. Eureka! /M3!
