2004 4dr SUV, ext. 290-horsepower 5.3L V8
4-speed automatic 4WD w/low range
16 mpg nothing to write home about, but acceptable for a vehicle of this size, weight and capability. see full Chevrolet TrailBlazer review

I recently purchased slightly larger tires and my fuel economy is suffering by 10% compared to stock tires, but I was anticipating this anyway. see full Chevrolet TrailBlazer review

Low teens in town, and 24mpg tops on the highway make this a less than ideal economy car. see full Pontiac G8 review
2009 4dr Sedan 256-horsepower 3.6L V6
5-speed shiftable automatic RWD
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
