We're still waiting for the new Corvette Z06 to break cover, which will use the same 5.5-liter flat-plane crank V8 engine as the C8.R race car. But this isn't the first time the Z06 has shared components with its race car equivalent. In the latest episode of Jay Leno's Garage, the chat show host checks out a very special Corvette Z06.

Based on a 2006 Chevrolet Corvette Z06, the Corvette C6RS was built by Pratt & Miller, General Motors' racing division that achieved several class wins in Le Mans with its Corvette C6.R race car. Launching just before the Corvette ZR1 arrived, the Corvette C6RS is essentially a road-legal version of the C6.R race car. Pratt & Miller wanted to build the ultimate road-going Corvette, and they certainly succeeded.

Under the hood is a K-tech aluminum block, naturally-aspirated 8.2-liter V8 engine developed by K-Tec producing 600 horsepower and 650 lb-ft of torque, paired with a Tremac T-56 transmission. This enabled the C6RS to hit a top speed of over 200 mph, making it one of the first road-legal Corvettes to break the 200-mph barrier. Apart from the door skins, roof panel, and hatch, every body panel is finished in lightweight carbon fiber, and the result is glorious to behold.

Remember, this was at a time when carbon fiber body panels on cars were not as common as they are today. Compared to the standard Z06, the Z6RS is around 1.5 inches wider and boasts superior aerodynamics thanks to the functional louvers fitted to the front fenders and rear brakes. Custom suspension can also raise or lower the ride height by around three inches for when you want to park it on a driveway.

As for the cabin, Leno praised the C6RS for having "the greatest Corvette interior I've ever seen." Pratt & Miller spent 150 hours stitching the interior, and it shows. Some people complained the Corvette's interior doesn't match the quality of a Ferrari or Lamborghini cabin, but there were no complaints here. It also has heated seats, which was a rare luxury in performance cars at the time.

When the Corvette C6RS launched back in 2008, it would have set you back $185,000 - and that doesn't include the cost of the donor Corvette Z06. That put it in the same price range as a Ferrari or Lamborghini. Only seven examples of the C6RS were built, and the car featured in Jay Leno's Garage is the very first one that was built for Leno to be shown off at the 2006 SEMA show. Since he bought it in 2006, Leno has clocked up around 10,000 miles in the C6RS and the car still rides on the same tires it came with 14 years ago.
