Grand Prix G8
It wasn't the one with the biggest crowds, or the flashiest paint job, but the G8 was certainly one of GM's most intriguing concepts. Why? Because even with its available supercharged V6 and capable chassis, the current Grand Prix just doesn't have enough hustle to compete with the world's finest two-door coupes. But add the G8's 350-horsepower V8 and all-wheel-drive system to the mix and the story begins to change a bit. Throw on a set of 19-inch wheels, drop it an inch, and add 13-inch cross-drilled brake rotors and now you're talking about a sport coupe that can wipe the floor with just about anything.
Of course, Pontiac doesn't have crates full of 19-inch wheels and cross-drilled rotors laying around the engineering center, but they do have plenty of power-packed V8s and the Versatrak all-wheel-drive system at their disposal. Throw in a T-56 six-speed tranny from the soon to be departed Firebird and Pontiac would have the hottest sport coupe on the market this side of an M3.
