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.
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.
This vehicle pioneered the advantages of “Active Suspension” and had GTP Corvette race car technology. Built at the Bowling Green Plant, this vehicle was developed as a prototype for a limited edition run in the 1990 model year. Chevrolet ordered it to be built with a complex, high-tech active suspension that includes an Eaton hydraulic pump and Moog actuators. This car and the technology inside of it led to the Active Handling system GM released in 1996.
"Hot" is an apt description of this special coupe's drivetrain. Its 6.6-liter engine produces 512 horsepower and 523 lbs.-ft. of torque. Mated to a four-speed automatic transmission and featuring a 3:41 geared limited slip differential and four-wheel independent suspension, this "Vette takes a backseat to no other vehicle. The White Shark Corvette also features power rack-and-pinion steering to precisely pilot this vehicle and four-wheel disc brakes with ABS.
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.
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.
CERV IV was nothing more than a C4 with the all new powertrain and interior in it. Read the commentary of a car magazine reporter: "We suspect that the first, very early prototypes of the all-new, Gen III ran on the dynos at GM Powertrain sometime in the early spring of 1993. In-vehicle testing began at the GM Milford Proving Ground in the first week in May of 1993 with the "Chevrolet Engineering and Research Vehicle IV-A".
In 1983, Bertone began to explore the possibility of approaching the US market with the Ramarro, an exercise in applied technology around mass-produced mechanics. The Ramarro, which means "green lizard" in Italian, was created on the chassis of the well-known Chevrolet Corvette, and the underlying concept aimed to modify the layout of the mechanical components.
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.
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.
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 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.
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.
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.
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.
Corvette Of The Day: 2003 Italdesign Moray Corvette
The Moray project, presented for the first time at the Geneva Motor Show on March 4, 2003, embodies the homage that Giorgetto and Fabrizio Giugiaro wish to pay to the fifty-year era of the Chevrolet Corvette, the supreme symbol of the American sports car. Touched by drifting tides with long and slender front lights, bringing immediately to mind the Moray, the English term for the eel-type fish, muraena helena, found in Mediterranean waters.
SIDESWIPE takes the form of a sleek, vision concept dreamed up by the Corvette designers at GM. The design is influenced by the original Stingray race car, introduced in 1959, but also draws on Corvette heritage cues from other generations. It brings them together in a futuristic shape that seems to be equal parts racecar and space ship.
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. 
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.
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.
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.
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.
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.
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.
The XP-895 was one in a series of experimental Corvettes built to explore alternative engine placements and chassis layouts. This vehicle features an 400 cid small block V8 mounted transversely in a mid-engine position. It utilizes a Turbo Hydramatic transmission via a bevel gear box. The body panels are all aluminum.
Duntov laid out three design concepts that took decades to implement. The first was his proposal for the 1957 Q-Corvette. This design called for the following: an all-aluminum, fuel-injected small-block engine, four-wheel independent suspension, four-wheel disc brakes, and a transaxle. This design concept arrived in 1997 as the C5.
