The 1957 Corvettes offered buyers more choices than ever before. New colors, power accessories, creature comforts, and most important, high-horsepower, fuel-injected engines finally made the Corvette “America’s Sports Car.” Of interest was the new fuel-injected Corvette, which was the fastest American car produced that year. The hottest variant produced 283 horsepower from 283 cubic inches of displacement. With one horsepower per cubic inch, it was a remarkable figure for a performance car at the time.
