M3 averages 16.6 mpg. Spirited driving brings it to single digits. There is hardly any need for that, given the recent engine advances. see full BMW 3-Series review

16 mpg for light city/highway driving. 16 gallon fuel tank limits range to about 300 miles for typical owners (assuming you run the tank dry). see full BMW 3-Series review

Less than the A3. Though the base 328i has a larger 6 cylinder engine while the A3 is a 4 cylinder turbo. 328i is also larger and heavier. It is more closer toa wagon while the A3 is closer to a hatchback. see full BMW 3-Series review

I average 20-22 mpg. getting expensive to run the car. I wish it was in the mid 20s, but 6 cyl and awd I guess it could be worse. and its not direct injection engine (reminds me to buy the injector cleaner stuff!) see full BMW 3-Series review

While you might say 'why bitch if you can afford the car?' the mpg can be SHOCKINGLY bad. I knew what I was getting into, and yes, I can afford it, but wow. My True Delta average is 16.5mpg but that can dip into the 12's bumper to bum see full BMW 3-Series review
