The Chevrolet Corvette first offered fuel injection in 1957.
Chevrolet introduced Rochester mechanical fuel injection for the Corvette’s 283-cubic-inch V8 during the 1957 model year. The option helped the engine produce one horsepower per cubic inch when ordered in its highest-output form, a notable performance milestone for an American production car.
Earlier Corvettes used carburetors, and fuel injection was not standard equipment. Buyers could choose different engine outputs, so not every 1957 Corvette had the system. The technology metered fuel more precisely than a conventional carburetor and supported stronger high-speed performance.
This development is sometimes confused with later electronic fuel injection. The 1957 Corvette used a mechanical Rochester system, not the computer-controlled electronic injection that became common decades later. Chevrolet continued offering fuel injection on selected Corvette engines after 1957, reinforcing the model’s performance reputation.
