Chevrolet SS racecar prototype in checkerboard disguise at speed

A lot of speculation has been made with regards to the SS, the promised new Chevrolet rear-wheel drive performance sedan. The Holden Commodore-based muscle saloon will be prowling the open road as early as next year, while a NASCAR version is set to compete in 2013. Shots of the cars testing in their respective natural habitats have led to endless speculation, and it appears we now know which car will debut first.

Word from Speed is that the 2013 Chevrolet SS NASCAR Sprint Cup car is set to bow on Thursday, November 29 at the Wynn Las Vegas hotel and casino. The car will reportedly be shown in full race trim, sans sponsor graphics for Bounty, Skoal or Taylor Swift.

The Vegas debut will mark the introduction of the final vehicle to enter in the 2013 NASCAR season. Dodge unveiled its Charger racecar in March before leaving the race series. Toyota showed off its V8, RWD Camry NASCAR in May, while Ford debuted its race-spec Fusion in January of this year. The remaining entries are expected to (visually) bear a closer resemblance to their road-going counterparts.

While the SS racecar is debuting next month in Vegas, no mention of the production version SS was made. We are still under the impression that February 21, 2013 will still be the launch date for the road-going version of the rear-wheel drive Holden-based sedan that has GM enthusiasts so worked up.
