1955 Corvette EX87 Prototype

Built for outright top speed, this prototype Corvette was built by Zora Duntov. He successfully piloted the car to a two-way average speed of 150 mph in January of 1956 at Daytona. Later two more similar cars were built for the 1956 Daytona Speed Weeks in February. After initial resistance from Engineering, Duntov’s cam was delivered to the Proving Ground.

1955 Chevrolet Biscayne Concept Car

GM’s 1950s Motorama-mobiles were mostly pretty out-there, with flamboyant fins, rocket-inspired skegs and cockpits, and other flights of wild imagination. Frankly, many of them were a bit absurd and even childish. But there were a few that were somewhat down to earth, even rather brilliant, like this 1955 Chevrolet Biscayne.

1955 Prince Bertil Corvette

In August of 1955 GM styling created an exclusive Corvette for Prince Bertil of Sweden, who reportedly placed his order direct with Harlow Curtice, GM President. All modifications were confined to the exterior. Visible in the frontal view are an entirely new, larger grille assembly with flat black screen instead of teeth and the replacement of the front emblem by a large "V".

1955 LaSalle II Roadster

The engineers came up with a unit-body construction that relied on strength coming from the side sills of the chassis. These contained the exhaust which probably easily overheated the cockpit, especially in the coupe. Unfortunately, GM fitted fake V6 engines in both cars with a concept valve train that included dual overhead camshafts.
