This little concept mounted a 180-horse Wankel transversely, driving a new automatic transaxle being developed for the forthcoming X-body Citation. Designed by GM's Experimental Studio and built in 6 months on a modified Porsche 914 chassis by Pininfarina, the 2-Rotor made its debut at the 1973 Frankfurt show.
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.
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.
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.
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.
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.
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 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.
Based on Harley Earl’s Project Opel plaster model, the EX52 / 122 was the original concept car that inspired the nation and left countless consumers wanting a Corvette to call their own. This Corvette concept was introduced at GM’s Motorama in January 1953.
Though the first two prototype cars to carry the Astro namesake were relatively well known, the third entry in this conceptual saga was somewhat obscure and significantly more bizarre. At the 1969 Chicago Motor Show, Chevrolet unveiled the Astro III which was a gas-turbine prototype that featured a tricycle wheel arrangement.
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
Mid-Engine Prototypes: The 1985 Corvette Indy Concept, The 1986 Corvette Indy and the 1990 CERV III Since the introduction of...
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.
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 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.
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.
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.
The 1992 Stingray III / California Stingray Concept was developed by John Schinella (and team) at GM's Advance Concept Center in Los Angeles. The 1992 concept is a world away from the C4. But the dominant motifs of a smooth rounded Corvette did come to production on the C5. This prototype looks distinctly upmarket, the rear shares a shocking similarity to the Jaguar XK8, without a flat surface in sight.
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.
Chevrolet Corvette ZR-1 Spyder prototype, 1991, by ASC. An experimental styling prototype ordered by Don Runkle, Chevrolet’s chief engineer, to see how far the ZR-1 might be pushed in convertible form. The windshield was chopped in half and the seats were mounted directly to the floorpan. The black example in the National Corvette Museum was originally painted Sebring Silver with a Neutrino Yellow interior.
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.
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.
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.
This is no ordinary C4 coupe, but a GM Engineering test mule with VIN plate EX4607 proudly displayed in the windscreen, built in 1986 to test all the new-for-1988 features. This actual car must have spent weeks pounding round the General Motors Proving Ground at Milford, Michigan with longer runs on the road, testing all the changes for a year which saw the C4 suspension, steering and brakes vastly improved.
Chevyt presented a trio of Corvette Stingray concepts. Many of the items fitted to the cars are available through the Chevrolet Accessories and Chevrolet Performance catalogs. Designed with cruising in mind, the Stingray Atlantic convertible concept features stunning Blade Silver paint, while the Stingray Pacific concept is more race-inspired and the Stingray Gran Tourismo was created to commemorate the 15th anniversary of the Gran Tourismo video game.
How do you beat a slew of Fox-Body 5.0 Mustangs that seemingly dominated the roads in the late '80s? You take a 454 cu.-in. big-block engine and stuff into a C4 Corvette and call it "Big Doggie". An experimental vehicle used to determine how to convert from a small block to a big block. Its 454 big block V8 along with its orange paint make this high horsepower engineering study a one-of-a-kind standout in Corvette history. The car had as much HP as the '90 ZR-1 did and it was named "ZR-2" or "Big Doggie". Old dog, new tricks joke?
The Corvette Stingray Concept was developed as an internal design challenge to combine classic Corvette cues with surprisingly high-tech features, modern materials, and a striking new appearance. The car is well-appointed with a clamshell hood, scissor-style doors, ergonomic seats, rear-view camera with night vision enhancement, and a high performance hybrid drive. Interactive touch controls allow the driver to customize the power and efficiency of his or her ride.
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.
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.
