The original Dodge Viper was a game-changer. With its outrageous proportions and massive 8.0-liter V-10 engine, it outclassed pretty much anything else out of Detroit at the time. Except maybe this one-off V-12-powered Corvette.
Chevy built this experimental Corvette in the early Nineties as its answer to the Viper, and it’s a beast. Called the ZR-12, it uses the C4-generation ZR-1 as a base. The entire nose was stretched to accommodate the 600 cubic-inch V-12, built by Ryan Falconer Racing Engines. The all-aluminum engine was rated at 686 hp and 680 lb-ft of torque when new—far more than the then-new Viper’s output of 400 horsepower and 450 lb-ft of torque.
