[1] The Ramarro uses the chassis from a 1984 C4 Corvette, the same car used to unveil the C4 to the European press at the 1983 Geneva Motor Show.

Chevrolet gave Bertone that car to use to build the Ramarro, as well as a port fuel injection V8 engine from the newer 1985 Corvette.

[2] The engine remains mostly stock but the radiator and air conditioning have been moved to the back of the car, taking the place of the spare tire which was moved in front of the engine, in order to allow Bertone to design the body with a more tapered, sealed off nose for better airflow and aerodynamics.

The interior was retrimmed in specially patterned green leather that was picked to match the exterior and also to resemble the colour and texture of lizard skin, a nod to the Ramarro name.

Finally, the Corvette's original automatic transmission was kept but the shift lever was replaced by a large rotary dial gear selector in the center console.
