2003 Pontiac Grand Prix Real Gas Mileage: Pros
2002 4dr Sedan supercharged 240hp 3.8L V6
4-speed automatic FWD
BEFORE the switch to ethanol-mixed fuel, my supercharged V6 averaged 22mpg, getting 19 city and a staggering 34 highway. If you do long highway miles and want more comfort than any econo-box can offer, this is the car for you! see full Pontiac Grand Prix review
2002 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD
HORRIBLE. 12-16mpg combined with both city and driving. see full Pontiac Grand Prix review
