The 427 Limited Edition option, code Q8A and Z44, was limited to 505 examples globally with 427 destined for North American customers. As a retirement gift to Wil Cooksey, the Corvette plant manager from 1993 to 2008, he chose the color scheme and hand signed and numbered the underside of the armrest console lids on all 505 examples in which this example is #6. As part of the package, the seats and the floor mats have “427” embroidery, and the center-console trim plate is color matched.
Built exclusively for Hertz Rental Car, the Corvette ZHZ coupe was first introduced in 2008 as part of Hertz’s “Fun Collection.”  These Corvettes were part of a larger group of rental vehicles made up of cars like the Ford Mustang, the Nissan 350Z and the Shelby GT-H. The intent behind these rental cars was simple - provide consumers with an opportunity to rent (at a rate commensurate with the car's performance) a well-equipped sports car for a day, a weekend or even longer. 
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 2005-2013 Callaway Corvette was a specialist version of the C6 Corvette, built by Callaway Cars expert craftsmen and sold through selected Callaway/Chevrolet dealers. The 17th “C-Project” undertaken by Callaway first produced naturally-aspirated SuperNatural™ 450, 461, 490 (6.0L) and 550 (6.8L & 7.0L) horsepower Callaway Corvettes. In February 2006, Callaway returned to its positive manifold pressure roots, introducing Callaway “SuperCharged” Corvettes.
The Callaway C16 was Callaway’s 16th major automotive project. It was a limited production, bespoke automobile, built to order, by what the Press called “the best specialist engineers in the business”. These cars are seriously fast, beautiful, and exclusive. The C16 was a direct competitor for the Porsche GT3, the Lamborghini Murcielago, the Ferrari 599 GTB. It was both faster and more capable than its competitors, at less cost.
The Z06 arrived for the 2006 model year as a homologation vehicle in the third quarter of 2005 and is the lightest of all Corvette models. The Z06 was equipped with the largest-displacement small-block engine ever produced, a new 7,011 cc (7.0 L; 427.8 cu in) V8 engine codenamed the LS7. The engine has a power output of 505 hp and 470 lb⋅ft.
In addition to the limited-edition Corvette Victory Edition, a second special version of our favorite all-American sports car was introduced in spring, the Corvette Competition. This model, built in limited numbers on the basis of the C6 Corvette, bears strong links to motor sport too, in which the Corvette has proven highly successful. The Corvette Competition was competitively priced and one heck of a package.
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.
In 2005, the Corvette was chosen as the official pace car of the 47th Daytona 500. The car was based on a 2005 production model Corvette and it presented an excellent opportunity for the 2005 Corvette to showcase its true capabilities. The pace car was designed to honor the heritage of the historic Corvette race cars of yesteryear. It was finished in millennium yellow with over-the-top black racing stripe that runs from the hood to the trunk lid. It is powered by a 6.0L V-8 LS2 engine with 400 horsepower.
