2008 Pontiac G6 Real Gas Mileage: Pros
YearBody/PowertrainComment
2009 4dr Sedan 164-horsepower 2.4L I4
6-speed shiftable automatic FWD		 I opted to get the 4 cylinder 6 speed automatic because of the higher EPA rating and I have a fairly long commute to and from work. see full Pontiac G6 review
2007 2dr Coupe 224-horsepower 3.5L V6
4-speed shiftable automatic FWD		 Amazingly it gets 30+ on the highway. I usually drive in stop-and-go traffic but still get 20 mpg easily. see full Pontiac G6 review

4-speed automatic FWD		 Getting 25 city miles see full Pontiac G6 review
