The Corvette is a high-end Sports car that has been produced by GM since 1953. The car was designed by Harley Earl and named after the fast attack ship. However the first Corvettes produced gave somewhat lackluster performance due to their 'stovebolt' 6-cylinder engines. V-8 powerplants were soon introduced and the car rapidly gained in popularity. An unusual design feature for it's time was an all-fiberglass body. The Corvette is available in 2-door sports coupe and convertible models, and a 4-door sedan model has been considered by the GM development team. The Corvette has such name recognition that it is actually sold under its own marquee in Europe and Japan.
