The Corvette SS began life as an experimental race car, and was unveiled to the public at the 12 Hours of Sebring endurance race on March 23, 1957. The SS was in training for Chevrolet's debut at LeMans that year. The Sebring race was, in many ways, Chevrolet's inauguration into modern racing. But the SS never finished the race, much to the dismay of the racing community.
In the late 80s, Chevy was developing what some dubbed a ‘Super Vette.’ But the 1989 debut of the Dodge Viper sent GM engineers on a new path to develop a ‘Viper-Killer.’ It started with a factory test mule and the experiment was to see how a ZR-1 would perform if given more power and less weight. It was so fast it was called "Snake Skinnner", for it's ability to beat the Viper and Cobra.
The 1973 Chevrolet XP-898 concept car was built with a frameless fiberglass foam sandwich body and chassis. This two-seater sports coupe offered a unique look at alternative engineering approaches to future techniques in design and manufacturing. The entire body consisted of four lightweight fiberglass outer body panels.
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.
Chevrolet Corvette “Tiger Shark” Concept, 1997. A C5 Corvette powered by an alloy 742hp LS1 427ci supercharged V8. Other modifications included upgraded Brembo brakes, 18-inch Kinesis Motorsport K58 forged wheels and a hood dome to clear the supercharger. It was built by Detroit prototype shop Wheel-To-Wheel and sold for $112,200 in 2009 at the GM Heritage car auction.
The Carlisle Blue Grand Sport Concept is painted in a very cool Carlisle Blue exterior with exquisite Pearl White full-length racing stripes. This color combination is highlighted with Silver-painted Torque 2 wheels. The Corvette also benefited from carbon fiber front splitter and rockers, a full-width rear spoiler, and a Grand Sport style hood blanket. For the interior, Chevrolet has opted for Ebony/Titanium leather with blue stitching, a new Bose Premium Audio with nine speakers.
The Nivola may be considered Bertone’s homage to the most fascinating American sports car: the Chevrolet Corvette. The sophisticated mechanical unit of the ZR-1 was interpreted by Bertone in a European key. Bertone designed a special chassis to make a sporty "boat" with a mid engine. This mechanical layout made it possible to exploit all the power of the engine when accelerating and warrant perfect roadholding on bends.
On July of 1955, the Chevrolet design studio staff created a dream car for the 1956 GM Motorama shows, called Corvette Impala. The Corvette grille and grille surround are incorporated, as well as other Corvette components. This hardtop five-passenger sports sedan shows the name "Corvette Impala" on the front emblem and rear license plate.
Only Bill Mitchell could get away with this. Bill always managed to have a hot daily ride. Engineering prototypes that weren't street-legal stayed behind the fence, but many of the show car Corvettes managed to go home with Bill. His usual statement on his "design study" cars was, "This thing runs like a bear!" For the Mulsanne Bill added, "This is the best Stingray ever."
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.
In 1959, the bones of the SS were revived when Bill Mitchell secretly funded the Stingray race car. Mitchell purchased the chassis of the 1957 SS race car mule for $500 and had a design team create a new body. Mitchell felt the first generation Corvettes were too rounded and soft, so the Corvette Sting Ray Racer featured a sharper body edge that made it work.
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.
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.
In 1977, GM chairman Thomas Murphy gave the Aero-vette the green light. It was approved for production, and slated to be released in 1980. Despite being greenlit for 1980 production as the upcoming C4 Corvette, Arkus-Duntov's replacement Dave McLellan decided for a number of reasons (cost and tradition among them) to stick with the Corvette's tried and true front-engine configuration
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.
While it was understood that the Corvette Indy Concept would never be fully realized as a production vehicle, it paved the way for the creation of the twin-turbo CERV III. The CERV III (Chevrolet Engineering Research Vehicle No. 3) was introduced in January, 1990 at the International Auto Show in Detroit, Michigan. Like the latter iteration of the Corvette Indy Concept car, the CERV III was fitted with a 5.7 Liter, 32-valve, dual-overhead cam LT5 engine that featured twin turbochargers. It had 650 hp and 655 lb/ft of torque and top speed of 225 mph.
The XP-819, developed in the mid-1960s, was an engineering exercise to test a rear engine concept for the Corvette. The body was designed by Larry Shinoda. You can see styling cues in XP-819 that later appeared in Shinoda's famed "Sting Ray" design. A GM marine engine powers the car so the two-speed transaxle would operate properly. The entire chassis, suspension, and steering are custom made components unique to this car.
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.
One of the most beautiful concept cars created by GM was the XP-822 later called the Aerovette. Zora Arkus Duntov and his engineers had originally built two predecessors during 1969. John DeLorean, Chevrolet's general manager, felt the program was too expensive and canceled the car.
The first  of these cars was the 1985 Corvette Indy Concept vehicle.  It was developed as a “pushmobile,” meaning that it was a non-functioning, full-size clay mockup that was developed to test market interest in the concept.  The car featured the same mid-engine configuration that Zora Arkus-Duntov had always envisioned for the Corvette program. 
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.
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.
For the 2012 Grand-Am season, Chevrolet was the first to unveil it's new DPG3 bodywork. This Corvette body kit will be built by Pratt & Miller and will be sold to customer teams. These body kits will fit on any existing Coyote, Riley, or Dallara chassis. This Corvette DP will be powered by a 5.0L V8 making 530BHP @ 7,000rpms and 450ft-lbs at 5,500rpms. 
Chevrolet had actually planned on making a family minded sports car at a rate of 40 per year, and to call it "Corvette America." It was designed by California Custom Coach in Pasadena. The one prototype and five production cars that were assembled were built by cutting two cars in half which, when mated together, extended the wheelbase of the vehicle by 30 inches.
Somewhere in the second part of 1959, project XP-720 begins at GM Styling, to design a production Corvette based on Bill Mitchell's Sting Ray racer. It would become known as the C2 or second generation Corvette. In October of that same year, a clay mock-up of project XP-720 is completed and put on display for General Motors' management viewing.
The Corvette Rondine concept was built by Pinanfarina and introduced at the 1963 Paris Motor Show. The car started life as a 1963 split-window Corvette, which is all the more unusual because Chevrolet introduced the split-window coupe at the same time that Pinanfarina was introducing a custom-built Corvette based on that very same platform.
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 Astro II was one of the most significant case studies of Duntov’s outright refusal to let his mid-engine dreams die, and as such, ultimately entered the history books as a precursor to the eventual mid-engine, C8 Corvettes of today. The Astro II was designed in a way that was more representative of the Corvette’s typical styling cues, than that of The Astro I.
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.
