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.
This Sledgehammer reached 254.76 mph at the Transportation Research Center (TRC) in Ohio and became the world’s fastest street-legal car for some time. It was built up by Reeves Callaway in Connecticut as an example of what was possible with the new ZR1 and and turbocharging its LT5 engine. The result was a 898 bhp coupe that still retained luxuries such as air conditioning and a radio. It got this power by using a NASCAR-spec block with Mahle pistons and a massive turbo.
What you see before you is a 1982 Chevrolet Corvette that has been fitted with a rare Greenwood Daytona body kit.  The most extreme of the Greenwood brothers' kits, the Daytona body kit is a highly sought-after modification that was developed by race-winning specialists Burt and John Greenwood.
The Callaway C7 was a completely new, purpose-built car designed to embody the company’s motto: “Powerfully Engineered Automobiles”, carrying on the visual tradition of design by Paul Deutschman and offered in a limited production series. The C7 was the first complete, bespoke Callaway Automobile. This sportscar was equipped with a carbon chassis, front mid engine/rear transaxle design, 650 horsepower SuperNatural engine.
Offered from 1987 to 1991, the RPO-B2K upgrade was available from any Chevrolet dealer and also Callaway’s first major Corvette tuning program. Together, GM and Callaway made the upgrade package a Regular Production Order (RPO) which was the first time GM had outsourced such an option to a specialist manufacturer. It even had a factory back warranty. As the C4 updated, so did Callway’s program and by 1988, the B2K was pushing 382 bhp and 562 ft. lbs. of torque.
Reeves Callaway has always had a dream of competing a Corvette of his own at the 24 Hours of Le Mans, France. The idea begin with the body work for a street version, but one thing led to another, and a full race version was completed as well. The street version is almost identical to the race version because the hood, tail, rocker panels, and lower door halves, are all made of carbon fiber, just like the race version.
