2006 Pontiac Grand Prix Real Gas Mileage: 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...) see full Pontiac Grand Prix review
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. see full Pontiac Grand Prix review
