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".
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 Mulsanne Showcar, 1974. Created by Bill Mitchell, the Mulsanne was a development of several previous Corvette “specials”, the 1969 Aero and the 1970 Scirocco. By 1974 it had been bored out to 454 ci and fitted with an experimental Rochester fuel injection system, it also had a periscope rearview mirror system.
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.
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.
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.
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.
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.
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 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.
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.
There were several successful attempts to build a convertible ZR-1, most of them by private people. The DR-1 was a GM prototype to test the structural integrity of the ZR-1 chassis when it would be topless. The car was built by American Sunroof Corporation (ASC) for Don Runkle, who was the vice-president of Advanced Engineering Staff, which explains the “DR-1” designation. It was a standard convertible transformed to ZR-1 specs.
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.
The 1954 Corvette was outfitted with several unique design features. These were the results of two design exercises that included both interior and exterior upgrades. Outwardly, this styling concept is distinguished by its sharkfin headlights which effectively split each headlight down the center.
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.
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 2011 Chevrolet Corvette Z06X Track Car Concept was designed to suggest new components and a new idea for transforming a production Corvette into a serious and closed-course track car. This track car concept was developed and produced by Chevrolet in partnership with Pratt and Miller, the partners in Corvette Racing in the American LeMans Series. The competition-oriented modifications of the concept include a polycarbonate rear window, roll cage, safety harness, racing seat.
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
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 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.
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.
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?
Mid-Engine Prototypes: The 1985 Corvette Indy Concept, The 1986 Corvette Indy and the 1990 CERV III Since the introduction of...
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.
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.
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.
The Stingray that never was. The stretched version of this new Corvette model for 1963 has rear seating and was built as ordered by Chevrolet chief Ed Cole. Larry Shinoda designed this coupe, that never went into production because the demand for the two seated Stingray already was overwelming. A running prototype of a 2+2-seat C2 Corvette intended to compete with the Ford Thunderbird was built, but the project was canceled.
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.
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.
