The GTP is Pontiac Grand Prix with some performance extras: a supercharger, upgraded suspension and brakes, etc. A "sleeper" - a car that looks slow, but is not. Don't get me wrong - it is not a real sports car, but more of a sports sedan. You get V8 power, and V6 fuel economy. Also, this car has a good deal of modding potential.
1997 - 2003 Pontiac Grand Prix GTP - Stock 3.8L V6: 240 horsepower, 280 ft.lbs of torque. 0 - 60: about 6.6 seconds - not too bad. Fuel economy: around 18 city, 28 highway - not too bad either. 1/4 mile: around 15 seconds - again, not bad.
