There was no doubt Chevrolet was in the sports car business with the release of the 1956 model. It featured a new body, a much better convertible top with power assist optional, real glass roll up windows (also with optional power assist), and an optional hardtop. The 3-speed manual transmission was standard. The Powerglide automatic was optional. The six-cylinder engine was gone. The V8 remained at 265 cubic inches but power ranged from 210 hp to 240 hp. The volume was 3,167, a low number by any contemporary standard and still less than 1954's 3,640, meaning this was the third lowest-volume model in Corvette history. Rare options: RPO 449 special camshaft with the 240 hp engine (111), power windows (547).Delco Radio transistorized signal-seeking (hybrid) car radio, which used both vacuum tubes and transistors in its radio's circuitry (1956 option).
