Callaway (United States)

Callaway Cars Inc. was an American automotive manufacturer based in Old Lyme, Connecticut. Founded by Rena Callaway, the company initially specialized in selling turbocharger kits before expanding into the production of limited-edition vehicles for major automotive manufacturers. Callaway's first significant project involved creating turbocharged versions of the Alfa Romeo GTV/6 sedans, with a total of 36 units produced.

In 1985, Callaway developed its first twin-turbocharged Corvette, known as the C4, which generated 345 horsepower and achieved a top speed of 178 mph (286 km/h). This success led Chevrolet to offer Callaway conversions as factory options, complete with full warranty coverage. The company continued to innovate, designing the Aston Martin Virage V8 engine in 1989. By 1990, Callaway introduced the Corvette model named Sledgehammer, which boasted an impressive 880 horsepower and reached a record speed of 254.76 mph (409.91 km/h).

Throughout the 1990s, Callaway expanded its lineup with models such as the Super Speedster, a modified Corvette featuring a cut-down windscreen and twin rear headrests, equipped with a 700-horsepower turbocharged Corvette ZR-1 engine. The Super Speedster was priced at $300,000. The company also developed a series of normally aspirated vehicles called Supernaturals, which included the C6 Corvette, C8 Camaro, and C9 Impala SS, all featuring engines with over 400 horsepower.

In 1995, Callaway introduced the C7 LM, a significantly reworked Corvette designed for both street and racing applications. This model featured a more aerodynamic design and was capable of reaching 182 mph (293 km/h) in its street version, while the racing variant produced 475 horsepower. Additionally, Callaway collaborated with Range Rover to produce 220 units of the Cl I Limited Edition Range Rover, which featured 245-horsepower engines and distinctive black paint schemes. In 1998, the company launched the Cl 2, a Corvette-based sports car with an original body design, achieving a top speed of 190 mph (306 km/h) and participating in both racing and street use.
