The Duntov Turbo was built as a partnership between American Custom Industries (ACI), a company known for building replacement Corvette body panels, and Zora Arkus-Duntov. It was developed as a highly-stylized convertible sports car based on the production model Corvette. Each of the special Duntov Turbo's also came with a turbocharged V8.
As the story goes, when the Corvette ZR-1 came out in 1990, Dick Guldstrand saw an opportunity to create his vision of the perfect Grand Sport ride, instead of his name just getting slapped onto another Chevrolet product. He asked GM for fifteen ZR-1’s and some money. He got one car and permission to do whatever he wanted to do with it. And that’s exactly what he did. Called the "GS90", Dick's car would prove to be the most elaborate and expensive specialty Corvette ever built.
Chevrolet's introduction of the LT1 in 1992 as the base engine in the Corvette phased out the L98 based Callaway Twin Turbo. Previously, Callaway Corvettes made their increased power through positive manifold pressure; now they made it through increased displacement and finesse. Initially called the CL1 or CR1, they designated the chassis they were built upon. They were based on the pushrod LT1 cars (CL1) or the 32 valve DOHC LT5 ZR-1 cars (CR1).
To commemorate its quarter-century milestone, Callaway Cars collaborated with Chevrolet, arranging a production run of 25 uniquely prepared 2012 Corvette Grand Sport coupes and convertibles. General Motors supplied special parts and procedures on the Bowling Green production line to facilitate final assembly at Callaway factories. Then, the performance and identity components are installed by Callaway. The 25th Anniversary Edition produced 620 bhp and 555 lb-ft of torque.
The Callaway C7 was a completely new, purpose-built car designed to embody the company’s motto: “Powerfully Engineered Automobiles”, carrying on the visual tradition of design by Paul Deutschman and offered in a limited production series. The C7 was the first complete, bespoke Callaway Automobile. This sportscar was equipped with a carbon chassis, front mid engine/rear transaxle design, 650 horsepower SuperNatural engine.
Genovation GXE C7 Corvette Stingray
Genovation Cars unveiled an electric Corvette with more power under its hood than a Dodge Challenger Hellcat. They call their car the Genovation GXE, and it is an EV (electric vehicle) variant of the seventh-generation Corvette. The company decided that they would replace the factory LT1 engine found in all base-model C7 Corvettes with a pair of electric motors that, when working in conjunction with each other, provide over 800 horsepower and 700 pound-feet of torque.
