The story

A defining chapter in Chevrolet Corvette history.

Explore the ideas, engineering and context that shaped the Chevrolet Corvette Corvette C1, then continue into its specifications and place in the marque's lineage.

Origins

The car shown at the 1953 Motorama in New York was a styling exercise, EX-122, built under Harley Earl to see whether Chevrolet could sell a two-seat sports car. The response was strong enough that General Motors committed to production within months, which forced a decision that defined the car: with no time or money for steel tooling, the body would be moulded in glass-reinforced plastic. It was the first American car built that way in volume, and every Corvette since has kept a composite body.

Design and engineering

The first 300 cars, hand-assembled at Flint in 1953, were disappointing. The Blue Flame straight-six, lifted from Chevrolet's saloons and fitted with three carburettors, was mated only to a two-speed Powerglide automatic — an unthinkable combination for a sports car. There were no roll-up windows and no outside door handles. Sales in 1954 were poor and the model was close to being dropped.

In production

Two things rescued it. Chevrolet's new 265-cubic-inch small-block V8 became available in 1955, transforming the car's performance, and Zora Arkus-Duntov, a Belgian-born engineer who had joined GM in 1953, took charge of making the Corvette genuinely quick. A three-speed manual arrived alongside the V8, and in 1957 Chevrolet offered Rochester mechanical fuel injection on a 283-cubic-inch engine — an expensive option, and one of the earliest production fuel-injected engines in America.

Legacy

The 1956 restyle by Bob Cadaret gave the car its cove-sided shape and proper windows, and Bill Mitchell's 1961 revision added the ducktail rear that would carry over to the next generation. By 1962 the Corvette was profitable, competitive at Sebring and Le Mans, and no longer at risk.
