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
