6-speed manual RWD		 Its a 414 hp V8. It drinks a lot. see full BMW 3-Series review
2009 2dr Coupe 414-horsepower 4.0L V8
7-speed automated manual RWD		 I only get 18. This car should get more like 23, much like a vette or cts. see full BMW 3-Series review
2009 4dr Sedan 414-horsepower 4.0L V8

2009 2dr Coupe 414-horsepower 4.0L V8
6-speed manual RWD		 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
2008 4dr Wagon 230-horsepower 3.0L I6
6-speed shiftable automatic RWD		 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

6-speed shiftable automatic AWD		 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
