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. 
The Zagato company took a C7 Corvette Z06 and transformed it into the IsoRivolta GTZ, a "spiritual descendant" of the Iso Grifo A3/C (Corsa).  The original A3/C race car was developed by Giotto Bizzarrini not long after he left Ferrari, where he had served as cheif engineer behind the 250 GTO, which is revered as the world's most expensive car.  Bizzarrini purportedly fancied the A3/C as his "own personal evolution of (and improvement upon) the GTO design."
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.
