Pontiac Grand Prix Fuel Economy: Pros
YearBody/PowertrainComment
2006 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD		 Good for a speedy V6 and a huge car.
2006 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD		 it was listed as being better than the impalla
2005 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD		 Thus far, I have averaged 23 and 26 mpg, both times have had roughly a 70 mile highway trip out of 200 miles. Overall, I find this to be acceptable.
2002 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD		 HORRIBLE. 12-16mpg combined with both city and driving.
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!
Pontiac Grand Prix Fuel Economy: Cons
YearBody/PowertrainComment
2006 4dr Sedan 303-horsepower 5.3L V8
4-speed shiftable automatic FWD		 Great V8 exhaust note and instant acceleration comes at the cost of about 19 mpg in combined driving, versus 25 with my new car. That is a 30% increase. (the new car is 600 pounds lighter though...)
2005 4dr Sedan 303-horsepower 5.3L V8
4-speed shiftable automatic FWD		 17-19 mpg in the city. 25 If I drive on the intersate. 30 is possible at 60mph. Most of my driving is in the city. The beautiful v8 makes it impossible to stay out of the gas, but it can run on REG fuel.
