Corvette came of age in 1957 when Chevrolet gave it the engine to match its improved handling and refined styling, the latter judged by many enthusiasts as the most aesthetically pleasing of the first generation. The base engine was enlarged from the 195 HP 265 CI V-8 to the new 4-barrel equipped 283/220 HP small block, a hotter version of which produced 270 horses. An early fuel-injected version generated 250 horsepower, but the car reached a new height in May 1957 with the introduction of a more developed Rochester fuel-injection system that put out a dependable 283 horsepower at 6200 RPM. Much was made in Corvette advertising about the new milestone of 1 horsepower per cubic inch, a record at the time. Fuel injection was costly, however, and buyers flocked to the optional 245 and 270 HP engines that featured dual Carter 4-barrel carburetors on an inline aluminum intake manifold. After its mid-run introduction the new 4-speed manual transmission, the first ever in a Corvette, became one of the most popular options and was soon swapped in to a number of factory 3-speed cars. The optional auxiliary hardtop from the factory, now in its second year, was another highly popular item that was ordered with almost two thirds of the Corvettes produced that year, which also saw the last appearance of single headlights in a Corvette. This beautiful Onyx Black convertible incorporates a dual-quad 283 CI engine, a 4-speed manual transmission and matching Black hardtop. Silver coves and a Red interior highlighted by full wheel covers and Whitewall tires complete this handsome first generation Corvette.
