In a class where four cylinders, modest equipment and unassuming looks are all too common, Pontiac Grand Prix backs up the bad-boy swagger of its WideTrack stance with the power of a standard V6. And with the GXP comes the biggest, most powerful V8 in the class.* With each model of the 2008 Grand Prix, a balance of interlocking technologies lets you confidently explore the performance driving experience. Officially, your registration will read "sedan," but Grand Prix feels like a four-door, five-passenger sports car.
