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

6-speed shiftable automatic RWD		 Is very low in stop-and-go traffic. Gets better with time, I understand. see full Pontiac G8 review
