Looking at the mileage records for vehicles in the Edmunds.com long term fleet I usually find that I get higher fuel economy than other drivers. So I was waiting for that effect to kick in with the 2002 BMW M3.
Lifetime average for the M3 is 17.4 mpg and I only improved the efficiency to a measly 19.6 mpg on the last tank after driving 277 freeway miles. I couldn't even crack 20 mpg!
This car is impossible to drive calmly. It was never intended to provide good fuel efficiency. It was built to deliver driving pleasure and even at its advanced age it does that quite well.

In the 5,000+ miles weve driven the M3 since we bought it late last year, we have yet to give you an update on the fuel economy. And while you generally dont buy an M3 for its fuel economy, we thought somebody still might be curious about it.
Best tank: 22.4mpg
Worst tank: 13.0mpg
Lifetime average: 17.9mpg
