1986 Corvette Indy Concept

The 1986 Corvette Indy Prototype was developed beyond clay modeling to the point of a fully-functioning, drivable car, though it was clearly understood that this car would never evolve beyond the prototype stage.  Like the clay mock-up before it, development of the mid-engine Indy prototype began in 1985, pulling design cues from its predecessor.

1996 Guldstrand Grand Sport 90 Nassau Roadster

To understand why the Guldstrand GS-90 coupe and convertible differ so much, keep in mind that during the course of the C4 development cycle, no ZR-1 convertibles were planned, so the base C4 convertible had to be used in building a GS-90 Nassau Roadster, as it was called. The coupe, however, had the advantage of using the ZR-1 platform right from the get-go.

1993 Corvette 40th Anniversary ZR-1

In 1993 just 448 ZR-1 Corvettes were produced and only 240 of them were 40th Anniversary Edition cars. The 40th Anniversary Package consists of a deep and glossy Ruby Red exterior finish over a matching Ruby Red interior with leather adjustable sport seats. A Corvette with both of these highly desirable packages is rare and special. At the heart of the ZR-1 is the 405-horsepower LT5 V8 engine mated to a 6-speed manual transmission.

1988 Callaway Corvette “Sledgehammer”

This Sledgehammer reached 254.76 mph at the Transportation Research Center (TRC) in Ohio and became the world’s fastest street-legal car for some time. It was built up by Reeves Callaway in Connecticut as an example of what was possible with the new ZR1 and and turbocharging its LT5 engine. The result was a 898 bhp coupe that still retained luxuries such as air conditioning and a radio. It got this power by using a NASCAR-spec block with Mahle pistons and a massive turbo.

1984 Corvette PPG Indy Pace Car

The 1984 PPG Indy Pace Car Corvette was special from the very beginning- in several ways. Initially, it was created as a one-off concept car that would be designated as one of the official Pace Cars for the PPG Indy Car World Series of races. It was custom-built by PPG in cooperation with the Chevrolet Division of General Motors. The 205 HP 350 was replaced by a 450hp, 401 cubic-inch V-8.

1991 Chevrolet Corvette ZR-1 Spyder

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.

1996 Corvette Collector Edition

Chevrolet knows their clientele, and with the 1996 Corvette Collector's Edition LT4, the automaker put together a special package that would entice hard-core 'Vette fans with a unique tribute to the outgoing C4 model. The $1250 option brought unique Sebring Silver Metallic paint, 5-spoke wheels, and, of course, special badges and embroidery. It also received the upgraded LT4 powerplant available in the Grand Sport, and with 330 horsepower on tap.

In 1990, dealers could order cars destined for the World Challenge race series.

1992 Corvette CERV IV Concept

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".

1987 – 1991 Callaway Corvette B2K Twin Turbo

Offered from 1987 to 1991, the RPO-B2K upgrade was available from any Chevrolet dealer and also Callaway’s first major Corvette tuning program. Together, GM and Callaway made the upgrade package a Regular Production Order (RPO) which was the first time GM had outsourced such an option to a specialist manufacturer. It even had a factory back warranty. As the C4 updated, so did Callway’s program and by 1988, the B2K was pushing 382 bhp and 562 ft. lbs. of torque.

1991 Callaway Corvette Speedster LM

The offspring of collaboration between Corvette performance guru Reeves Callaway and designer Paul Deutschman, the Super Speedster LM is an astonishing step up on the original Speedster, taking full advantage of the ZR1’s Lotus-engineered, all-aluminum DOHC engine and 6-speed manual transmission. One of only three twin turbocharged and intercooled LT5 engines built by Callaway, it delivers a pavement-shredding 766 HP.

1993 Callaway CR1 Corvette

When Chevrolet changed gears to the LT1 engine, Callaway revealed their new SuperNatural line and the CR1 based on the ZR1’s LT5. Options for the CR1 included the radical Aerobody, German upholstery and special wheels, brakes and exhausts. The CR1 used a larger displacement to produce either 475 or 490 bhp.

1994 Callaway SuperNatural C6 Corvette LM

Reeves Callaway has always had a dream of competing a Corvette of his own at the 24 Hours of Le Mans, France. The idea begin with the body work for a street version, but one thing led to another, and a full race version was completed as well. The street version is almost identical to the race version because the hood, tail, rocker panels, and lower door halves, are all made of carbon fiber, just like the race version.

1989 Corvette DR-1 Concept

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.

1989 Corvette Challenge Car Series

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.

1986 EX4607 (ZR-1 Prototype)

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.

1990 Corvette ZR1 Active Suspension

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.

1983 Corvette (The One & Only)

Within the National Corvette Museum's Skydome sits the only remaining 1983 Corvette; a car best characterized as a survivor, in every sense of the word. According to the Macmillan Dictionary, a survivor is, "someone or something that still exists after every other member of a group has died or been destroyed." This as it may, the 1983 Corvette lives up to this title.

The 1992 Stingray III Concept

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.

1996 Corvette Grand Sport

Priced at an additional $3250  for the coupe or an additional $2880 for the convertible, the Grand Sport package included exclusive Admiral Blue paint and featured a single white stripe that ran the length of the body as well as two red accent stripes (also known as “Sebring Stripes”) on the driver side front fender.  This unique paint scheme was deliberately developed by GM to pay homage to the classic Corvette Grand Sport Racer of the 1960’s.

1987 – 1988 SCCA Trans-Am Corvette

The story of this Chevrolet begins with Fords - specifically, the purpose-built IMSA Mustangs and SCCA Trans Am Mercury Capris that became major forces in those series in 1984-85. In 1985, a Mustang built by Jack Roush and chassis firm Protofab took a young John Jones to the IMSA GTO crown and a Roush Protofab Mercury Capri had done the same in the Trans Am championship.

1985 Corvette Indy Concept

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.

1995 Corvette GT1 C4 ZR1

This car was created by Doug Rippie. His claim to fame was the Corvette Challenge Series. Rippie loved racing Corvettes in the US, but, his life-long dream was to take on the world-class marques at Le Mans. So, when Chevy introduced the C4 ZR1 the opportunity was opened up. Via his collaboration with MerCruiser and Lotus Engineering, all with Chevy’s blessing, the "Black Widow" program created special street and race versions of the LT5 engine. This engine made 525hp.

1989 – 1991 Callaway Corvette Speedster

In 1989 Callaway introduced a Speedster which was the culmination of their styling, engineering and trimming talents. Their first example was a bright green ZR1, which had a severely chopped windscreen, no side mirrors, eighteen inch wheels and a vibrant blue leather interior stitched purposefully from Germany. Nothing about Callaway’s Speedster was reserved, and this is especially true when investigating the specification. The car had 450 horsepower.

1988 Corvette 35th Anniversary Edition

While not exactly a "collector's edition" Corvette in its own right, it nonetheless has become a uniquely identifiable and collectible Corvette from the fourth-generation era. 1988 marked the 35th anniversary for Corvette, and so it was decided that Chevrolet should commemorate the milestone by introducing an anniversary-edition model. This anniversary car was the first of its kind in a decade, given that Chevrolet opted not to manufacture a Corvette in 1983.
