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.
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.
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 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.
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 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.
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.
Two racing icons will unite when Lance Armstrong, seven-time Tour de France winner, drives the 2006 Chevrolet Corvette Z06 pace car to lead the field to the start of the 90th running of the Indianapolis 500 on May 28, 2006. For a record 17th time, a Chevy will pace the race, and it's the eighth time for a Corvette to be leading the pack. The only changes made to prepare it for this year's role were the addition of strobe lights and racing safety gear.
