1988 Callaway SledgeHammer C4

Callaway SledgeHammer Corvette — American speed record holder The Callaway SledgeHammer Corvette (C4) is a unique supercar created by Callaway Cars in 1988 based on the Chevrolet Corvette C4. Its main goal was to show the true potential of the Corvette and set a new speed record among road cars.

Under the hood was a 5.7-liter twin-turbocharged V8 engine specially developed by Callaway.

The engine developed about 898 horsepower and more than 1000 Nm of torque.

It was paired with a 6-speed ZF manual transmission and rear-wheel drive.

This combination allowed the SledgeHammer to accelerate to 100 km/h in 3.9 seconds and reach a top speed of 410 km/h — an incredible figure for the late 1980s, which made the car a legend.

The exterior was refined with Callaway AeroBody aerodynamic bodywork designed by Paul Deutschman.

It improved handling and stability at high speeds while retaining the recognizable lines of the Corvette.

The interior remained close to the standard Corvette but included additional instruments and sporty elements to match the extreme character of the car.
