Let's not forget that the anti-lag system for the turbos may or may not use a consequential amount of fuel.

Lots and lots of reasons to think the new m3 is going to get great gas mileage, don't get me wrong, but we don't know enough about the anti-lag system either. I'm guessing it could decrease fuel economy by 3-5% though.
