2000 TVR Cerbera Speed 12
Founded in 1946, TVR is a British sports car institution, although it's never gained the immediate recognition of peers like Lotus. In the '90s, TVR was producing some of the wildest sports cars available, with the Griffith, Chimaera, and Cerbera. When TVR wanted to go endurance racing, they began developing a race car based on the Cerbera that would go on to become the Cerbera Speed 12. Rapidly changing regulations in the GT1 class would render the Cerbera Speed 12 ineligible to race, so TVR promptly began work on a road-legal version — of which one was built. Power came from a 7.7-liter V12 making a claimed 790 horsepower, with a figure near or over 1,000 horsepower likely. TVR chairman Peter Wheeler deemed the Cerbera Speed 12 too high-strung for road use, and only one was built. That car is now up for auction, making this an ultra-rare example of a time in automobile history never to be seen again.
