Every Concept & Prototype

The Corvettes that were never sold: the Motorama show cars of 1953–56, Mitchell’s Stingray Racer and Mako Sharks, Duntov’s CERVs and his thirty-year campaign of mid-engine prototypes from the XP-882 to the Aerovette and the Corvette Indy, the Bertone and Italdesign cars, the Sting Ray III that previewed the C5, the Stingray Concept that previewed the C7, and the design studies of 2025. Sixty-two of them.

Two near-identical 1963 Sting Ray convertibles left GM Design under special work orders: one for the Chicago Auto Show, one for retired styling chief Harley Earl. Earl's car later brought $925,000 at Mecum.
Built for Indianapolis sponsor Ozzie Olson, this Mitchell special previewed 1965's side-exit exhausts with simulated pipes and added six taillights, custom floor grates and pearlescent blue paint.
The most innovative of Bob McDorman's GM Styling Corvettes, Bill Mitchell's Sting Ray XX previewed Astro ventilation with ventless door glass and hid chaser lights in its door panels.
Pink Pearl paint to match the door of the Knudsens' Florida home, pink sidewall tires, FMK-engraved seat belts and a preproduction 396 big-block make this 1964 coupe one of GM Design's wildest executive specials.
Drawn in GM's Los Angeles studio while the Corvette fought cancellation, the Stingray III previewed the C5's taillights and decklid but would have cost $300,000 per car.
GM wanted the $3 million rotary Corvette forgotten; it sat crated on a Luton rooftop for a decade until Tom Falconer talked Chuck Jordan out of crushing it. The survival story.
Fifty-six years before the C8 went mid-engine, Larry Shinoda hung a V8 behind the driver on a 90-inch wheelbase. The result previewed the C3 and ended in a crash on a test drive.
Only three drivable examples are believed to survive of the 25 active-suspension ZR-1s GM built with Lotus, the cars that led to Active Handling in 1996 and Magnetic Ride Control in 2003.
After its 1965 Paris debut, Chevrolet was flooded with requests to build the Mako Shark II. Its retractable bumpers never made production, but its shape became the 1968 Stingray.
Labeled a Corvette but built to feed Chaparral, the GS-II paired a steel monocoque, an all-aluminum 327 and a one-speed automatic. At just 1,450 lb it reached 198 mph at the GM proving grounds.
Two rotary engines bolted together for 420 hp, gullwing doors and a silver-leather cabin: the Four-Rotor was GM's most serious mid-engine Corvette proposal of the 1970s.
One 1968 Corvette lived three lives as Aero Coupe, Scirocco and Mulsanne. The Scirocco phase paced Can-Am races with the same all-aluminum ZL-1 that powered the dominant McLarens.
Skirted rear wheels, smooth wheel discs and a roadster windshield made the Astro-Vette a slippery oddity, but its nose and tail showed up on production Corvettes in 1973 and 1974.
A helicopter turbine, a single front wheel and a power canopy: the Astro III looked like a business jet because John DeLorean wanted it to. The strangest car in the Astro saga.
Duntov built the Astro II from parts-counter Camaro and Corvette pieces to prove a mid-engine Corvette could reach production. GM said no, and the C8 took 50 more years.
Chevrolet's general manager wanted a road-going Mako Shark, so engineering built him one: side exhausts, Rose Pearl paint, a white stripe and a chrome-dressed fuel-injected 327 that forced the battery behind the seat.
Inspired by a shark Bill Mitchell caught in the Bahamas, the XP-755 previewed the Sting Ray two years early with a double-bubble canopy, hidden headlights and a supercharged 327. It now lives at the GM Heritage Center.
When the Viper arrived, a group inside Chevrolet built Conan: a ZR-1 stretched 8.8 inches to swallow Ryan Falconer's 683 hp V12. It melted its tires on the first quarter-mile run.
GM's chairman approved it for 1980 production, then Dave McLellan chose a front engine instead. How the gullwing Aerovette came within a signature of becoming the C4.
Four fiberglass skins, a shot of expanding urethane foam and fifteen minutes later you had a car body. The XP-898 tested a manufacturing idea rather than a styling one.
Built by Wheel-to-Wheel for GM Special Vehicles, the Tiger Yellow concept packed a 742-horsepower supercharged 427 and a hood vent that later appeared on the C7. Why the body kit flopped.
Built to skin the coming Viper, the Snake Skinner shed 250 pounds with magnesium, Kevlar and Lexan, then gained a 475 hp MerCruiser LT5. Specs, the Milford 185 mph run and its 2009 auction are all here.
A split-window Sting Ray rebodied by Pininfarina and shown at the 1963 Paris Motor Show, the Rondine traded coves for Ferrari Lusso curves and sold for $1.6 million in 2008.
GM Styling cut a hole in the hood to show off the fuel-injection manifold, added side pipes that turned out to be plastic, and painted it candy apple red. Today the car is valued at $1.25 million.
Equal parts race car and spaceship, the Sideswipe concept let GM's Corvette designers run free of production rules. Ed Welburn explains why the 1959 Stingray racer inspired the no-holds-barred 2009 vision concept.
Twin turbos, 650 horsepower, scissor doors and a $300,000-plus build cost: the CERV III was GM's last serious try at a mid-engine Corvette before the C5, and its roofline lived on in that car.
Reynolds Metals built an aluminum twin of the steel XP-895 and cut 450 pounds, then cost killed it. Decades later Dave McLellan had it rebuilt and drove it. The full account.
The only SR-2 built to be driven on the street belonged to GM's president. Car #1636 left the line in 1956 and came back with a fuelie 283, a 100-pound louvered hood and Curtice's own blue metallic paint.
The car that birthed the Duntov cam. A 1954 test mule tagged EX87 got a plexiglass windscreen, a tail fin and a 307 ci V8, then ran 163 mph at GM's Arizona proving ground.
Ordered crushed in 1958, the Biscayne XP-37 lay in pieces at a Sterling Heights junkyard for 25 years until Joe Bortz dug it out. Its rear bumper design ran on Corvettes through 1967.
A 512-horsepower nod to the 1965 Mako Shark, dressed in Shark Sand tri-stage pearl with Klein Karoo ostrich leather inside. The specs and details of Chevrolet's 2002 SEMA show Corvette.
The Tri-Five Nomad began life as a Corvette. Five Corvette-bodied wagons toured the 1954 Motorama circuit before Harley Earl fast-tracked the design into Bel Air production, and only three survive today.
1964 Chevrolet CERV II Corvette
Duntov planned six CERV IIs to take on the GT40 at Le Mans; GM allowed one. Its twin-transmission all-wheel drive and 490 hp overhead-cam V8 made it a precursor to the mid-engine C8.
1959 Chevrolet Corvette CERV 1
Duntov's first mid-engine argument weighed 1,450 pounds and made 352 hp from an aluminum 283. The CERV I ran Pikes Peak, Riverside and 206 mph at Milford, then GM bought it back for $1.32 million.
Just 35.5 inches tall, with a clamshell roof that lifted the seats up with it, the Astro I previewed the 1968 Corvette's nose while hiding a rear-mounted Corvair engine.
Corvette XP700 Concept
Red, then silver, then gone. Bill Mitchell's XP-700 wore a loop bumper, an aluminum-coated double-bubble roof and the tail that shaped the 1961 Corvette before a 1961 memo hints it became XP-755.
GM wanted to know whether a topless ZR-1 could work, so ASC built one for Advanced Engineering chief Don Runkle. The answer was no, and the DR-1 remains a one-off.
Chuck Jordan saw the mid-engine Indy as a rolling showcase for satellite navigation, CRT gauges, Lotus active suspension and carbon construction. Its Lotus-tuned V8 program fed directly into the 1990 ZR-1.
Bill Mitchell could not let the Mako Shark II retire, so it came back in 1969 with a new roof, flying-buttress tail and a ZL-1 427. What changed and why it still matters.
Ed Cole wanted a four-passenger Corvette to rival the Ferrari 2+2; Bunkie Knudsen thought it would ruin the car's image. Larry Shinoda's one-off XP-796 was the result, and Knudsen's diary tells how he killed it.
The first Corvette to wear a Stingray badge never went on sale. XP-87 raced to a 1960 SCCA title, previewed the C2 and then got a windshield and passenger seat for Bill Mitchell's weekends.
A five-passenger Corvette almost happened. The 1956 Impala show car put a 225 hp dual-quad 265 under a brushed stainless roof, lit a bar-graph speedometer, and gave Chevrolet a nameplate still in use.
A Swedish prince skipped Europe's sports cars and ordered a Corvette straight from GM's president. GM Styling answered with a one-off wearing a flat black grille screen, a big V emblem and a deck-lid fuel filler.
A Cadillac dream car with Corvette bones. The LaSalle II Roadster paired open rear wheels and brake drums cast into the wheels with a dummy V6, then survived its death sentence in a Michigan salvage yard.
A fastback Corvette with a jet-afterburner tail: the 1954 Corvair concept took Harley Earl's aviation obsession to the Motorama. Its 155 hp inline six was pure C1 underneath, and slow sales killed it.
Sharkfin headlights, a prototype steering wheel and a blue no production car wore: this 1954 Corvette was a GM Styling design exercise, documented on 1955 and 1956 shop orders and restored by Werner Meier.
DeLorean cancelled it, then revived it to spite Ford's Pantera. The XP-882 became the Aerovette, approved for 1980 production until Dave McLellan chose a front-engine C4 instead.
Born from an argument between Zora Arkus-Duntov and Frank Winchell over whether a rear-engine V8 could handle, the XP-819 crashed in testing, went to Smokey Yunick in pieces and was later resurrected.
Bill Mitchell's personal Stingray wore 1975 bumpers, four rectangular headlamps and a 454 built from a ZL-1. The last life of the Aero Coupe and Scirocco car, shown in New York in 1975.
Two cars named Corvette SS, and nobody at GM seemed to notice. This modified 1956 show car hit the Waldorf in January 1957 just as the secret XP-64 racer was being finished for Sebring.
Before the first production Corvette there was EX-122, the Motorama show car built from Harley Earl's Project Opel. Public response in January 1953 pushed GM from prototype to production in six months.
Built in secret for $1.2 million so GM management could not cancel it, CERV IV was a C4 shell hiding the next-generation V8 and interior that became the 1997 C5 Corvette.
An engineless C4 shipped to Hawtal-Whiting to package the LT5 should have been crushed. Instead it ended up on an Essex farm, was sold, regretted for 14 years and finally reclaimed, prototype stickers intact.
Fixed seats, a moving steering wheel and pedals, four-wheel steering and a pop-up rollover bar: the black cherry Sting Ray III was a 1960s-flavored vision of the Corvette that cost too much to build.
GM never sold a ZR-1 convertible, but this ASC-built Spyder prototype came close, with a chopped windshield, aero bars and a signed hood the National Corvette Museum is still trying to find.
Stingray Atlantic Concept
Chevrolet's SEMA 2013 headliners were three C7 Stingrays, the jet-inspired Atlantic, the track-ready Pacific and a Gran Turismo 6 tribute, all dressed in catalog accessories.
Three C4 Corvettes got 454 big-blocks at GM's Arizona proving grounds, and the orange 1989 roadster nicknamed Big Doggie was the last. Here's how the ZR-2 offered ZR-1 pace at half the price and still died.
A year after the C4 launched, Corvette engineers were already sketching its mid-engine replacement. The silver 1985 Indy pushmobile tested public appetite and previewed the turbine wheels of later C4s.
Far more radical than what Zora Arkus-Duntov had in mind, this Styling Staff proposal gave the mid-engine chassis gullwing doors, rear air intakes and a periscope for rear vision.
The Corvette that previewed the C5 in 1957. Duntov's Q-Corvette put the transaxle in the back, the brakes inboard and an aluminum 283 up front, then died with the 1958 recession.
GM's 1954 Motorama fielded a Corvette quartet, and the Hardtop was the one that foretold a production feature. Its removable fiberglass top took until 1956 to reach buyers, along with roll-up windows.
Chevrolet and Pratt & Miller turned a Z07-package Z06 into a closed-course track car, removing the radio and carpet and adding an SCCA roll cage, racing seat and adjustable carbon wing.
Corvette Racing's skull mascot inspired this Grand Sport show car, built almost entirely from Genuine Corvette Accessories to show how any owner could build a Jake special.
A front-engine Corvette proposal from late 1963 with doors that swung up and forward around the windshield pillar, side pipes and a short bobbed tail, prepared by Henry Haga's team at GM Styling.
The C2 started as the Stingray Racer with a coupe roof. XP-720's October 1959 clay already had the door vents that would move to the front fenders on the 1963 Sting Ray.

FAQs

What was the first Corvette concept car?

The Corvette itself: the EX-122 shown at the GM Motorama in New York in January 1953 was a concept car that went into production six months later. It survives, the oldest Corvette in existence.

Which Corvette concepts became production cars?

The Stingray Racer and the Mako Shark I became the 1963 Sting Ray; the Mako Shark II became the 1968 Corvette; the Sting Ray III set the C5’s proportions and the CERV IV its chassis; the 2009 Stingray Concept gave the C7 its face; the 2013 SEMA Pacific and Atlantic cars became 2015 design packages; and the mid-engine idea of the XP-882 and Aerovette became the 2020 C8, fifty years later.

Why did it take so long for a mid-engine Corvette?

Duntov built mid-engine prototypes from 1964 (CERV II) through 1977 (the Aerovette, approved for 1980 production), and his successors built the Corvette Indy and CERV III in 1986–90, but each time the cost, the tooling and the question of whether Corvette buyers wanted it stopped the car. The C8 of 2020 is the Aerovette’s idea with a modern budget.

Where are the Corvette concept cars now?

Most survive: the GM Heritage Center holds the Stingray Racer, the Mako Shark I, the Manta Ray, the Astro I, the Aerovette, the Sting Ray III and the Stingray Concept among others; the National Corvette Museum and private collections hold more (the CERVs, the SR-2s, the XP-819, the Reynolds car). The Motorama Nomad, Corvair and Impala were destroyed, and the 1957 SS sold at auction for $7.7 million in 2025.

What is the most important Corvette concept?

By influence, the 1959 Stingray Racer, which gave the car its name, its shape and its racing credibility in one stroke; by what it almost was, the 1977 Aerovette; by what it started, the 1953 EX-122. The ten-greatest list, linked above, argues the order.

Has Chevrolet shown a Corvette concept recently?

Three in 2025: a hypercar design study from GM’s Leamington Spa studio in Britain, and the electric CX and hybrid CX.R Vision Gran Turismo at Monterey Car Week, the first public look at ideas beyond the C8. Corvette’s chief engineer said in 2026 that a Z06X is possible again, sixteen years after the SEMA concept.

Are the concept cars ever for sale?

Rarely, which is why the sales make news: the 1957 Corvette SS ($7.7 million, 2025), the Pontiac Banshee, the XP-819 and the Reynolds XP-895 have changed hands; the GM Heritage cars do not. The market reports cover the sales.

Where are the race cars and the special editions?

On their own pages: the race cars (the SR-2, the SS, the Grand Sports, the Corvette Racing cars) and the special editions (the badged factory editions). The cars that began as engineering or show cars and went racing appear here too.
