CORVETTE LISTS

Every Mid-Engine Corvette Prototype (1964–1990)

Eight times between 1964 and 1990 Chevrolet built a Corvette with the engine behind the driver, and eight times it stayed a prototype: the CERV II, the Astro II, the Two-Rotor and Four-Rotor Wankels, the aluminum Reynolds XP-895, the Aerovette that was approved for production and cancelled, the Corvette Indy and the CERV III.

Zora Arkus-Duntov argued for a mid-engine Corvette from the early 1960s until his retirement in 1975, and Chevrolet came within a signature of building one twice: the Aerovette was approved for 1980 production in 1977 and cancelled after Duntov and Bill Mitchell retired, and the Corvette Indy program of 1986–90 produced two running cars. The C8 of 2020 was the first to reach a showroom, 56 years after the CERV II.

The site’s guides to the concept cars: the mid-engine prototypes above and the rest, from the 1954 Motorama cars to the C8 program.

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.

FAQs

What was the first mid-engine Corvette prototype?

The 1964 CERV II, the Chevrolet Engineering Research Vehicle II built under Zora Arkus-Duntov: a mid-engine, all-wheel-drive racing prototype with a 6.1-liter V8 meant to take on the Ford GT40 and Ferrari at Le Mans. GM never raced it. The CERV I of 1960 was a single-seat open-wheel test car, not a Corvette.

How many mid-engine Corvette prototypes did Chevrolet build before the C8?

Eight shown cars between 1964 and 1990 — the CERV II, Astro II, XP-897 Two-Rotor, Reynolds XP-895, XP-882 Four-Rotor, Aerovette, Corvette Indy and CERV III — plus the unshown XP-882 chassis cars of 1970 that the rotary and Aerovette show cars were built on. The C8 of 2020 was the first mid-engine Corvette sold.

Which mid-engine prototype came closest to production?

The 1977 Aerovette. GM approved it for production as the 1980 Corvette in 1977, with the 400-ci V8 in place of the Four-Rotor engine it was built with; it was cancelled after Duntov, Bill Mitchell and Ed Cole retired and the money went to the front-engine C4. The 1986–90 Corvette Indy program produced two running cars but was never meant for sale.

Why did GM build rotary-engined Corvettes?

GM bought a Wankel license in 1970 and planned the engine for the Vega and beyond; the 1972 Two-Rotor (a Pininfarina body on a Porsche 914 chassis) and the 1973 Four-Rotor (two GM rotaries joined, on the XP-882 chassis) were the Corvette versions. GM dropped the rotary in 1974 over fuel economy and emissions, and the Four-Rotor was re-engined with a V8 to become the Aerovette.

Where are the mid-engine prototypes now?

The Astro II, Aerovette, Corvette Indy and CERV III are in the GM Heritage Collection; the Reynolds XP-895 was kept by GM; the CERV II is privately owned and has sold at auction (RM Auctions, Monterey 2013, $1.1 million); the Two-Rotor passed to a British collector, who fitted a V8 after the rotary was removed.

Did any of the mid-engine prototypes influence the C8?

All of them, in the sense that the C8 is the layout Duntov asked for in 1964; more directly, the Corvette Indy and CERV III program of 1986–90 developed the structure and the LT5 engine that reached the C4 ZR-1 and C5, and the C8 team cited the Aerovette and CERV III as the lineage. The site’s C8 hub tells the production story.
