History;
Visually the 1957 model was a near-twin to 1956. Engine displacement increased to 283 cu in (4.6 L), fuel injection became optional, and a 4-speed manual transmission was available after April 9, 1957. Fuel injection first saw regular use on a gasoline engine two years prior on the 1955 Mercedes-Benz 300SL "Gullwing". Although the Corvette's GM-Rochester mechanical fuel injection used a constant flow system, as opposed to the diesel style nozzle metering system of the Mercedes', the Corvette's engine nevertheless produced about 290 bhp. This was underrated by Chevrolet's advertising agency for the 283 bhp at 6200 rpm and 290 lb⋅ft of torque at 4400 rpm 283 small-block V8 "One HP per cubic inch" 1 hp per 1ci slogan, making it one of the first mass-produced engines in history to reach 1 hp/in³. Pushed toward high-performance and racing, principally by Zora Arkus-Duntov who had raced in Europe, 1957 Corvettes could be ordered ready-to-race with special options. Fuel injection was in short supply and 1,040 Corvettes with this option were sold. Rare options: RPO 579E 283 hp engine with fresh air/tach package, RPO 684 heavy-duty racing suspension, RPO 276 15 by 5.5 in wheels, RPO 426 power windows, RPO 685 4-speed transmission.
