Unlike the standard all-wheel drive 996 Turbo models, the 996 GT2 was a rear-wheel drive model as GT2 class racing prohibited all-wheel drive. 476 horsepower were on tap from the retuned Mezger 3.6-liter flat six. In a concession to the light weight needed for racing, the GT2 did not have a rear seat or air conditioning. Two variants were available, the base model GT2, and the limited production Clubsport, equipped with extra racing features such as a roll cage, racing seats, harness, and fire extinguisher, among others. Around 1287 of the GT2 model were sold for model years 2002 and 2004. It was replaced by the 997 GT2 for model year 2008.
