Not sure why he is comparing gas mileage of the m5 with his old mercedes??
Sounds like it gets the same mileage as the current m3. 24-25 highway cruising with a few stabs of the throttle is exactly what the e90 m3 gets. I guess for such a drastic chang ein technology and direction I expected there to be a really big improvement.
The e60 m5 could easily get 21-23 mpg cruising on freeway with a few stabs of the pedal. For 2 mpg improvement seems like not overly impressive.
