Pontiac G6 Gas Mileage (MPG)

Unlike other fuel economy surveys, TrueDelta's Real-World Gas Mileage Survey includes questions about how and where a car was driven. So you can get an idea of the Pontiac G6's real-world MPG based on how and where you drive a car.

If you are not a TrueDelta member, you can see only five Pontiac G6 MPG gas mileage averages for each powertrain. Log in or join us to see them all.

What Our Members Are Saying about the Real Pontiac G6 MPG

Pontiac G6 Fuel Economy: 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.
2007 4dr Sedan 169-horsepower 2.4L I4
4-speed automatic FWD
Getting 25 city miles
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.
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.

YearBody/PowertrainComment
2008 4dr Sedan 219-horsepower 3.5L V6

The V6 I drove had MPG ratings slightly worse than the 4-cyl models I was looking at.
2007 2dr Hardtop conv. 217-horsepower 3.5L V6
4-speed shiftable automatic FWD
Not good enough.
