2010 Chevy Camaro GS Racecar Concept - front three-quarter view

The 2010 Chevrolet Camaro GS Racecar Concept, built for the SEMA show back in 2008 by Riley Technologies with assistance from GM's High Performance Vehicle Operations, will be offered for sale at the Mecum Auctions during Monterey Car Week next month.

The prototype motorsports Camaro was painted to resemble Mark Donohue's 1969 Camaro Trans-Am racecar, and it had a few performance modifications done to make it eligible to compete in Grand Am's Koni Challenge GS class. The production Camaro body-in-white was seam welded, the fenders, doors, hood and trunk were replaced with carbon-fiber pieces, a three-inch exhaust system with aftermarket mufflers was swapped in and engine, transmission and differential oil coolers were added. The stock Chevrolet LS3 V8 was dropped onto solid engine mounts and paired with a close-ratio six-speed manual gearbox, with upgraded brakes completing the package.

Mecum Auctions estimates this track-oriented prototype will bring in between $110,000 and $200,000 at the auction block.
