On display in the Chevrolet exhibit at the 1957 Chicago Auto Show was the Chevrolet 'Corvette' Impala Motorama dream car from 1956. Featuring a Corvette-like grille, fiberglass body, spoke wheels with knockoff hubs, the modern coupe styling had room for five passengers. The prototype was built on a 116.5-inch wheelbase chassis and powered by General Motors 265 cubic inch V8 engine. Showgoers did not know that the Impala dream car was a preview of the production 1958 Chevrolet Bel Air Impala hardtop, in name, side trim and roof design with reverse-slanted C-pillar.
