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.
Total Production for the 2008 Indy Pace Car replicas sold to the public was 500. The first replica rolled off the production line approximately March 4th, and the last was June 6th. There were 61 Corvettes built in early March, however only 60 cars shipped to the Indianapolis Motor Speedway to be used as rack” and “festival committee" vehicles which were distributed to their lucky drivers on April 9th and in use thru May 31st.
C6 Corvette LS7 7.0L Engine
GM’s was on mission to engineer a Corvette that built upon the line’s performance legacy. By all indications, this is a mission that was fulfilled. The Corvette’s engine bay was host to several outstanding powerplants during the C6’s run. From the base 6.0-liter LS2 to the ZR1’s beastly 6.2-liter LS9, the C6-era was never short on performance. Corvette finally caught up to European brands.
Corvette C6R
The Corvette C6-R race car debuted at the 12 Hours of Sebring in March 2005. The two-car, factory-backed Chevrolet sports car program competed in the production-based GT1 class (formerly GTS) of American Le Mans Series as well as the legendary 24 Hours of Le Mans in France. It was the most technically advanced sports car ever developed by GM, culling years of experience from the Corvette C5-R as well as the advancements brought forth from the next-gen Corvette C6 and Z06.
Corvette GT3 C6 Z06-R
During the summer of 2005, a decision was made to transform selected Z06 road cars into a new breed of racer to compete in the world's top GT3 championships. The first series to introduce this new GT3 class was the SRO and FIA's GT3 Championship. Based on their racetrack test results, Team Carsport saw instant potential in the car. Hezemans contracted Callaway Competition in conjunction with Koos Pettinga, manager at Corvette Europe, to convert the street Z06 into a Z06R GT3.
In late 2007 Corvette Europe approached the FIA seeking approval to race a C6 Coupe in the GT4 category.  After much study the FIA approved their request.  Kroymans shipped a new 2008 C6 Z51 six-speed coupe to Callaway Competition in Leingarten, Germany. In less than six weeks the Callaway team stripped the new car of all non-essential parts including carpet and standard seats. 
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.
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. 
Corvette LS3 Engine angle view
Upon the LS3’s release in 2007, this trend toward continual technological advancement was clearly evident. As the new power plant for the standard 2008 Corvette, the LS3 provided consumers with exactly what they had been craving, unsurpassed performance. With every reiteration, the LS small-block has become more powerful, efficient, and robust.
Known for their charismatic designs and superior performance, the pack-leading Pace Cars share a special place in Indianapolis 500 lore. History was made at the 2008 Indianapolis 500 when a pair of distinctive yet highly differentiated Corvette models served as the Official Pace Cars — one highlighting a commitment to fuel solutions and the other marking 30 years of Corvette's Pace Car heritage.
