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.

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.

The V6 I drove had MPG ratings slightly worse than the 4-cyl models I was looking at.

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.
