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

bad fuel economy, I guess thats why 2006-2008 models do have a trip computer but the trip computer was not able. 2009 to present all have same trip computer that provides MPG,distance to empty and somewhat of an improved gas mileage. see full Mazda CX-7 review
