Pontiac will become the first manufacturer to produce cars to meet the new GT regulations in 2005. The GTO race cars will have production-based LS2 small-block V-8 engines and retain the stock body design. They will incorporate safety features developed by GM Racing in the Corvette C5-R and Cadillac CTS-V racing programs. Teams and drivers will be announced at a future date.

The Grand American Rolex Sports Car Series will showcase the Pontiac GTO's potent capabilities. In production trim, the new-generation GTO offers a sophisticated blend of performance, handling, comfort and value. On the race track, the use of production-based powertrains and body panels will provide opportunities to demonstrate the GTO's virtues against an international field of competitors that includes Ferrari, Porsche and BMW.

The new 6.0-liter (364 ci) LS2 engine that powers the production 2005 GTO provides a strong foundation for the racing version. In stock trim, the LS2 produces 400 horsepower; with only minor modifications developed by GM Powertrain, the LS2 easily achieves the 450-horsepower maximum output specified by Grand American regulations. Open exhaust headers, a free-flowing induction system, a competition camshaft and a road racing dry-sump oiling system are the only changes from stock. The LS2 engine is heir to the rich racing heritage of GM's small-block V-8; the most successful production-based engine in motorsports.

In addition to the GTO road racing program announced today, Pontiac will continue its Pro Stock program in the NHRA Powerade Drag Racing Series in 2005.
