Low teens in town, and 24mpg tops on the highway make this a less than ideal economy car. see full Pontiac G8 review

The most MPGs I ever had was 25 and that was all highway driving at about 70. see full Pontiac G8 review

Not bad mileage figures given the size of the car and the beast of an engine, but this is not a car for the hybrid set. see full Pontiac G8 review
