Callaway C12

The Callaway C12 is a sports car, designed, developed and built by American manufacturer Callaway, between 1998 and 2001. It is based on the contemporary Chevrolet Corvette (C5), although unlike earlier Callaway efforts the bodywork was entirely different. The C12 retained the Corvette's glass and roof, door handles, and interior hardpoints.

The bodywork, designed by Paul Deutschman, is of GRP and kevlar on a hydroformed steel skeleton. The bodywork was built by German IVM Automotive. The brakes are ventilated discs all around, with an ABS system. The suspension is double control arms with coil springs over shock absorbers at all four corners.

The C12 was either equipped with a 6.2 liter V8 motor, or a tuned version of the 5.7 liter LS1 used in the Corvette C5 with multiple under-hood modifications, many of which increased horsepower. The 5.7-liter "Supernatural" engine produces 440 hp (328 kW) and 395 lb⋅ft (536 N⋅m) of torque, with the later 6.2-liter version producing 482 hp (359 kW). The larger LS6 engine was introduced after Chevrolet had introduced their more powerful Z06 derivative. Additionally, the C12 received modifications that enhanced handling capabilities.

According to Callaway, the C12's were built "to a standard rather than a cost" with high-profile customers such as Dale Earnhardt Jr., Otis Chandler, Andrew McKelvey, Ely Callaway, Rick Hendrick and Tommy Mottola buying the car. In total, 20 cars were produced with exposed headlights, two taillights as opposed to the traditional four, and complete leather-covered interiors dyed to the owner's specifications.
