1988 Chevrolet Callaway Corvette

#20 0f 125

Callaway Cars has become well established with modifying and even competing in motorsports with Corvettes. Perhaps the most famous Callaway models are the C5-based C12 and the C4-based ‘Sledgehammer,’ which broke the top speed record of 254.76 mph on October 26, 1988. The latter has a convertible sibling, simply called the Callaway Corvette Twin-Turbo Convertible. The exterior design of the Twin-Turbo Convertible features the AeroBody Package, designed by Paul Deutschman. This is the same package used on the Sledgehammer. This package improved the car’s aerodynamics and engine cooling system by revamping the airflow management both inside and out, which allows the car to comfortably reach at least 200 mph.

 

From 1987 to 1991, the Twin-Turbo Convertible was deemed an official GM option by Callaway, which could be executed at standard Chevrolet dealers in North America. Based on the C4 Corvette, it is one of the C4 Corvette models built by Callaway and the only model that has a twin-turbo conversion as an option, under the code RPO B2K. After the conversion, under the bonnet is a 5.7-litre twin turbo L98 V8 engine, mated to a 4+3 “Doug Nash” manual gearbox. This transmission is essentially a 4-speed manual with bolt-on 3-speed overdrive unit, which can be pushed top of the shifter.

 

Only 125 examples were made, making it one of the rarest modified Corvette models you could buy, especially coming from a respected company like Callaway. 

 

This example is #20 of the 125, with an exterior finish of Bright Red and a black leather interior. This particular example remained in the care of its original owner until 2020. Throughout the years, it has accumulated 10,340 miles on the odometer and has been kept in excellent condition both inside and out. The car also includes an owner’s manual and other valuable accessories. It is a unique opportunity for Corvette and Callaway enthusiasts to own a piece of history of the American icon.
