Second to NASCAR, Corvette Racing is the most successful motorsport program at GM for more than a decade. The dynasty continues as the latest 2014 Corvette C7.R debuts at the Detroit Auto Show.

The Corvette Z06 street car was developed alongside the hardcore C7.R racing machine. According to GM, the new aluminum frame in the C7.R is a remarkable 40 percent more rigid than the C6.R. An uprated 5.5 liter V8, restricted by United SportsCar Championship regulations, is mated to a rear-mounted transmission for optimal weight distribution.

The C7.R is the first Corvette racing car to feature direct injection. The benefits are obvious: the C7.R boasts more power, more precise throttle response and control, as well as better fuel economy. In racing, every little bit is the difference between glory and defeat. One less pitstop or a one-second quicker lap time can spell victory for a team.

Despite its aerodynamic benefits, the low hood does little to accomodate the C7.R's hardware. For example, the radiator is tilted forward to fit under the snug space. In addition, sharp frotn splitters provide more front end downforce. Of course, a gigantic GT wing sits on the back. Interestingly, the C7.R no longer features NACA ducts on its rear quarter panels to cool the transaxle and differential. The C7.R does not have the louvres over the rear haunches found on the Corvette Stingray either. Finally, the rear is dominated by an elaborate diffuser pieced together from large pieces of sharp carbon shards.

The 2014 Chevrolet Corvette C7.R will race at the Rolex 24 Hours of Daytona on January 23. Of course, the C7.R will compete at this year's 24 Hours of Le Mans as well, where it has already won seven class victories. Be sure to check out the promo video of the C7.R below:
