Buick Rendezvous Real Gas Mileage: Pros

2005 4dr SUV 185-horsepower 3.4L V6
4-speed automatic FWD
Generally good mileage. I generally have a light to medium foot, will use A/C, and most driving is a mix of suburb and hwy. Tend to get just over 20mpg. On strict highway driving with a load, get 23 plus. see full Buick Rendezvous 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
