Chevrolet unveils 2013 Sprint Cup car

NASCAR has allowed its three manufacturers to redesign its 2013 cars to more closely resemble production cars.

"I think it's one of the most important moves that NASCAR and the manufacturers have made in a very long time," Chevy driver Kevin Harvick said. "Just for the fact that the cars on the race track will be very significant in looking like the cars on the showroom floor. I think from a manufacturer's standpoint it's probably the most important move that has happened in a really long time. For the fans to have that relevance from the race track to the showroom is important."
