The SS previews Chevrolet's long-rumored rear-wheel drive sedan.

Chevrolet has unveiled the new SS stock car that will compete in the 2013 NASCAR Sprint Cup.

Visually, the SS features a more coupe-like shape than many of the cars that are currently racing around the oval track. It is powered by a small-block V8 that is expected to send over 700 horsepower to the rear set of wheels.

Although by no means street-legal, the SS stock car closely previews Chevrolet's long-rumored rear-wheel drive sport sedan. Also called SS, it will make its debut next February in the days leading up to the season-opening Daytona 500 race.

"With the SS, Chevrolet is delivering a true rear-wheel-drive NASCAR race car that is very closely linked to the performance sedan that will be available for sale, ensuring that our most loyal enthusiasts will have the opportunity to experience the same thrill every day on the open road that our race car drivers enjoy on the track on race day," said GM North America President Mark Reuss.

The upcoming SS will be Chevrolet's first rear-wheel drive four-door sedan in 17 years. It will ride on the same Zeta platform that underpins the Camaro and is scheduled to hit showrooms across the United States as a limited edition model in late 2013.
