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

Getting 25 city miles 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
2006 4dr Sedan 201-horsepower 3.5L V6
4-speed automatic FWD
Even with a 6 cylinder, and my overzealous driving, I regularly got 28-29 MPG. This is a mix of highway and city driving in a very hilly area. see full Pontiac G6 review

The V6 I drove had MPG ratings slightly worse than the 4-cyl models I was looking at. see full Pontiac G6 review

2005 4dr Sedan 200-horsepower 3.8L V6

Thus far, I have averaged 23 and 26 mpg, both times have had roughly a 70 mile highway trip out of 200 miles. Overall, I find this to be acceptable. see full Pontiac Grand Prix review
2002 4dr Sedan 200-horsepower 3.8L V6

HORRIBLE. 12-16mpg combined with both city and driving. see full Pontiac Grand Prix review
2002 4dr Sedan supercharged 240hp 3.8L V6
4-speed automatic FWD
BEFORE the switch to ethanol-mixed fuel, my supercharged V6 averaged 22mpg, getting 19 city and a staggering 34 highway. If you do long highway miles and want more comfort than any econo-box can offer, this is the car for you! see full Pontiac Grand Prix review
Pontiac Grand Prix Real Gas Mileage: Cons

2006 4dr Sedan 303-horsepower 5.3L V8
4-speed shiftable automatic FWD
Great V8 exhaust note and instant acceleration comes at the cost of about 19 mpg in combined driving, versus 25 with my new car. That is a 30% increase. (the new car is 600 pounds lighter though...) see full Pontiac Grand Prix review
2005 4dr Sedan 303-horsepower 5.3L V8
4-speed shiftable automatic FWD
17-19 mpg in the city. 25 If I drive on the intersate. 30 is possible at 60mph. Most of my driving is in the city. The beautiful v8 makes it impossible to stay out of the gas, but it can run on REG fuel. see full Pontiac Grand Prix review
