In 2006, the company behind the Corvette C6.R pulled out all the stops and developed a Corvette (based on a Z06 donor car and a lot of amazing engineering) that featured an unprecedented amount of horsepower and torque under its hood while packing ultimate luxury inside its ultra-wide carbon-fiber body. The car, which was revealed at the SEMA show in 2007, was called the C6RS Corvette.
The early C4's had their problems, what with the 1984 Cross-Fire Injection and its unusual 4+3 manual transmission. By the late 1980's, the fourth-generation Corvette had evolved into a more desirable automobile, thanks in part to the arrival of the ZR-1. 
The Duntov Turbo was built as a partnership between American Custom Industries (ACI), a company known for building replacement Corvette body panels, and Zora Arkus-Duntov. It was developed as a highly-stylized convertible sports car based on the production model Corvette. Each of the special Duntov Turbo's also came with a turbocharged V8.
The L88 was a special option package developed under the direction of Zora Arkus-Duntov, director of GM’s performance division. First introduced in 1967, the L88 Corvette featured a highly modified version of Chevy’s 427-cubic-inch V-8 engine. Although this engine received a factory horsepower rating of 435, actual engine output was somewhere between 540 and 580 horsepower, giving the “stock” L88 enough power to run a quarter-mile in the high-11-second range!
It was announced on July 23rd, 2010 that the 2010 NASCAR Brickyard 400 will be paced by this Green and White Corvette Grand Sport Coupe while Arctic White Corvette Grand Sport Convertibles wil serve as Festival (parade) cars. Camaro Coupes will also be used as support vehicles. The color is reminiscent of Bowling Green Metallic, last seen in 2001. This marked the 17th time that Chevy paced the Allstate 400 at the Brickyard.
2006 Chevrolet Corvette Z06 Daytona 500 Pace Car
The Corvette Z06 that served as the Daytona 500 pace car was mechanically identical to those available at Chevrolet dealerships. It was the fastest vehicle ever offered by Chevrolet and General Motors. With 505 horsepower (377 kw) and 470 lb.-ft. of torque (637 Nm) from its 7.0L all-aluminum, racing-inspired engine, the Corvette Z06 leaps from 0-60 mph in 3.7 seconds and has a top speed of 198 mph. The Corvette Z06 Daytona 500 wears a unique paint scheme.
