The Corvette team decided to one-up the Viper with four extra cylinders, they decided on one of Ryan Falconer’s stunning, all aluminum, 600-cubic-inch, 683hp, 680 lb-ft V-12 racing engines. The biggest challenge was the fact that the all-aluminum V-12 engine was 8.8-inches longer than the production Corvette engine. So the front end of the ZR-1 would have to be stretched 8 inches. This test car was named Conan, after his raw, beastlike charisma.
There were several successful attempts to build a convertible ZR-1, most of them by private people. The DR-1 was a GM prototype to test the structural integrity of the ZR-1 chassis when it would be topless. The car was built by American Sunroof Corporation (ASC) for Don Runkle, who was the vice-president of Advanced Engineering Staff, which explains the “DR-1” designation. It was a standard convertible transformed to ZR-1 specs.
The Centennial Edition came finished exclusively in a Carbon Flash Metallic finish with satin-black graphics. Special badging graphics signifying Chevrolet’s racing history, including an image of Louis Chevrolet on the B-pillars, were added as accents to the cars finish. The wheels were also finished in satin black. All models also received red brake calipers. The exterior color scheme of the Centennial Edition Corvette is reinforced inside the car.
