What Our Members Are Saying about the Real Gas Mileage of the BMW 2-Series

BMW 2-Series Real Gas Mileage: Pros
YearBody/PowertrainComment
2014 2dr Coupe turbocharged 320hp 3.0L I6
8-speed shiftable automatic RWD		 The #3 pro of this hardcore sports car, surprisingly, is fuel economy. All the major brands are taking surprising lengths to be eco-friendly. In 'Eco' mode, the 300 horsepower M235i can manage a surprising 22/33 mpg. There is a MPG bar constantly running below your speedometer, constantly challenging you to try to make it as big as possible. The car also features regenerative braking to power the car's electrical systems. see full BMW 2-Series review

Pontiac G8 Real Gas Mileage: Cons
YearBody/PowertrainComment
2009 4dr Sedan 415-horsepower 6.2L V8
6-speed shiftable automatic RWD		 Low teens in town, and 24mpg tops on the highway make this a less than ideal economy car. see full Pontiac G8 review
2009 4dr Sedan 256-horsepower 3.6L V6
5-speed shiftable automatic RWD		 The most MPGs I ever had was 25 and that was all highway driving at about 70. see full Pontiac G8 review
2009 4dr Sedan 361-horsepower 6.0L V8
6-speed shiftable automatic RWD		 Not bad mileage figures given the size of the car and the beast of an engine, but this is not a car for the hybrid set. see full Pontiac G8 review
2009 4dr Sedan 361-horsepower 6.0L V8
6-speed shiftable automatic RWD		 Is very low in stop-and-go traffic. Gets better with time, I understand. see full Pontiac G8 review
