by It’s hard to believe, but there was a Chevrolet Corvette with a V12. And no, it’s not the work of some tuning studio, but a factory prototype. Recently, it was rolled out on the roads. 
The decision to fit a V12 under the hood of a Chevrolet Corvette was made in the early 90s. It was just when the Dodge Viper debuted with an eight-liter V10, and Chevrolet decided to create an even cooler car.
The Chevrolet Corvette ZR-12 (as the prototype was named) was equipped with a massive 9.8-liter V12 from a speedboat. It developed 686 hp and had a torque of 920 N·m. In tests, the Corvette covered a quarter mile in 11.6 seconds and reached 214 km/h at the finish, making it faster than the Viper. 
Of course, installing the V12 required reinforcing the chassis and lengthening the wheelbase, but this Corvette ended up being only 45 kg heavier than the standard model. Why didn’t the Corvette ZR-12 go into production?
It was all about the price – one such engine cost 45 thousand dollars at the time, meaning it was more expensive than the base 1990 Chevrolet Corvette.
