Carl Renner was responsible for the Nomad which was essentially a Corvette built with an extended station wagon roof. This meant the Corvette shared its lightweight fiberglass body, ‘Blue Flame’ inline-6 engine and curvaceous styling with the Nomad.
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.
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.
Duntov started off with a ‘54 Corvette as his test mule. He knew that accomplishing his goal would require two things: more power and improved aerodynamics. First, he removed the stock windshield and built a small windscreen. A tonneau cover was then added to the passenger side, and a fairing with a long fin was added to the rear deck behind the driver’s head.
If you were a senior GM employee, one of the perks was being able to have your own custom built for you. Bill Mitchell was known for it, but this SR-2 Lookalike was built for GM president Harlow Curtis, who was president of GM during the period that the SR-2 were developed. The lookalike was built by GM’s styling staff and presented to him.
Chevrolet Corvette Coupé, 1957, by Ghia Aigle. Designed by Giovanni Michellotti a one-off built on a ‘54 Corvette chassis by Carozzeria Ghia in Switzerland. The Ghia Corvette was powered by a Blue Flame 6 in-line engine with a 4-speed manual gearbox
Corvette XP700 Concept
Designed and built under the personal supervision of Bill Mitchell, the wild-looking XP-700 used many regular Corvette components (frame, chassis parts and engine). Bill Mitchell had a lot of “customs” built for himself. This XP-700 previewed the new tail of the upcoming 1961 Corvette.
When the crankshaft broke on Gary Laughlin’s Ferrari Monza he had had enough. Being the owner of several Chevrolet dealers, he turned to Peter Coltrin to have a few rebodied. Fortunately, they pursued Sergio Scaglietti who made three fastback coupes on the Corvette chassis.
1959 Chevrolet Corvette CERV 1
The “CERV-1” (Chevrolet Engineering Research Vehicle) was developed as a research tool for that company’s continuous investigations into automotive ride and handling phenomena under the most realistic conditions. The car was built at the Chevrolet Engineering Center at Warren, Michigan in a special project headed by Mr. Zora Arkus-Duntov, Chevrolet Staff Engineer.
This one-off 1961 Vignale Corvette was built for the 1961 Salon de l'Automobile in Paris, France. It was based on a 1960 Corvette chassis and built by Italian coachmaker Carrozzeria Vignale. The body was designed by Gordon Kelly.
The XP-755 was designed and the prototype was built in the beginning of 1961. Bill Mitchell was very excited about the double-bubble roof, the side exhausts and rear. It is equipped with a single four-barrel carburetor that produces upwards of 425 horsepower. The Corvette XP-755 Concept had a streamlined design, pointed snout and outlandishly future looking elements everywhere. The 1961 Mako Shark I (XP-755) was an early concept.
The GS II (Grand Sport II) was a test vehicle completed in late 1963 by Chevrolet Engineering Center (C.E.C.). The chassis was constructed of spot-welded sheet steel and was fitted with narrow tires. With only minor testing done at GM’s test facility in Michigan, the vehicle was shipped to Texas to the Chaparral Cars test facility.
The Corvette built for 'Bunkie' Knudsen is a 1963 Chevrolet Corvette styling car known as the "Bunkie" Knudsen Corvette, built for Chevrolet general manager Semon E. "Bunkie" Knudsen. Finished in Rose Pearl with a full-length White racing stripe, it is outwardly distinguished by its chromed header-style pipes.
In 1963 GM Design put together two special Corvettes according to special work orders. The first was delivered fresh to the 1963 Chicago Auto show, while a nearly identical version was gifted to the retired Harley Earl. These Vettes received numerous modifications from GM Design including and a new custom interior and sidepipes.
1964 Chevrolet CERV II Corvette
The CERV II was entirely Zora’s car. The CERV II was conceived early in 1962 and developed over the next year, after the GS program was squashed. The car was built under Zora's direction between 1963-'64. Zora had it in mind to develop a separate line of racing Corvettes but the idea got terminated by management.
"Bunkie" Knudsen ordered it up in the spring of 1964 for his wife, Florence. This car is as much of a gem today as it was when Florence Knudsen first saw it, so says its current owner, Chevy dealer and noted Corvette collector Bob McDorman. It had custom Pink Pearl paint and custom pink leather interior.
This one-off Corvette was custom-built by GM Styling under famed design chief Bill Mitchell, especially for the famed industrialist and Indianapolis racing sponsor Ozzie Olson of Olsonite fame. Among its special modifications including custom floor grates that were a trademark feature of the GM Styling specials
For the 1964 New York World's Fair, Bill Mitchell and his Styling team at the Tech Center customized a production Sting Ray under Shop Order #10361 with a variety of items that transformed the already impressive Corvette into a showpiece like no other.  An opening was cut into the center of the car's hood exposing a polished fuel injection manifold with the Corvette crossed flags in its very center.
The most innovative of the Bob McDorman Collection’s GM Styling Corvettes is this Blue Metallic one-off enjoyed by GM Styling legend Bill Mitchell. The unique paint is accented with a custom made die cast front grille and matching dual front fender vents. A willing 327 CI engine gave this gem all the performance the boss could have asked for...
When first introduced to the world by Pontiac in 1964, the car showed so much promise that Chevrolet (allegedly) put a swift end to its development to prevent its production from hindering the sales of the Corvette.  Afterall, with the introduction of the 1963 Split-Window Corvette, Chevy was finally seeing an increase in sales, something lacking for most of the first-gen.
To clothe the 1965 mid engine Corvette chassis, the designers at Styling Staff proposed a much more radical shape than Zora Arkus Duntov, the main force behind a mid engine Corvette, had in mind. It would have provided rear vision solely through a periscope. The design had bold air intakes at the rear and a split windscreen that lifted up with the gullwing doors.
The Manta Ray was actually the 1965 Mako Shark II (XP-830) with a few upgrades, so it featured many of the Mako II's outward features, such as side exhausts and a lower-body (along the rocker panels) silver paint job. The front end had a pointed chin spoiler and the headlights used 2 banks of 3 quartz-halogen lights.
1988 Corvette Challenge Car Series
The 1988 Corvette Challenge Series was created by John Powell of Powell Motorsports. Chevrolet built fifty-six identical Corvettes for the first year of the Corvette Challenge in 1988. Each was equipped exactly the same, with all standard equipment, the 245hp Cross-Fire fuel injection engine, Doug Nash 4+3 transmission, Z51 Handling Suspension package.
The 1989 Corvette Challenge cars had a unique option code from the factory, it was "R7F". The documentation from GM clearly indicates that the cars were produced for the express purpose of racing in the SCCA Corvette Challenge Series. There is also documentation that identifies by serial number, all Corvettes produced with these option codes. Therefore, it is relatively easy to validate the authenticity of any Challenge car.
The 1990 Escort World Challenge Series Corvette R9G's were only available for one week. Only race teams were allowed to order this very rare Corvette through dealerships. The 1990 Corvette had its own code like the '88 & 89's did, it was dubbed the "R9G" Corvette. The cars were produced for the express purpose of racing in the SCCA World Challenge Series. In 1990, dealers could order cars destined for the World Challenge race series.
The Corvette team decided to one-up the Viper with four extra cylinders, they decided on one of Ryan Falconer’s stunning, all aluminum, 600-cubic-inch, 683hp, 680 lb-ft V-12 racing engines. The biggest challenge was the fact that the all-aluminum V-12 engine was 8.8-inches longer than the production Corvette engine. So the front end of the ZR-1 would have to be stretched 8 inches. This test car was named Conan, after his raw, beastlike charisma.
