Why it matters
This is the only road-going Cerbera Speed 12 ever built, the sole street-legal product of TVR's most extreme project. Its V12 was formed from two of TVR's own straight sixes, making it the most powerful car the small Blackpool firm ever attempted.
How rare is it?
Six separate kinds of rarity – never combined into one number.

|---|---|---|---|
| Total model productionThe single road car, offered at Silverstone Auctions in May 2023 | 12 | Surviving examples | Independently researched |
| Total model productionsingle street-legal car | 11 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
The Speed 12 began as Project 7/12, a GT1 racer based on the Cerbera coupe and intended to take on the McLaren F1 GTR, Mercedes-Benz CLK GTR and Porsche GT1. When a change in the racing rules ended those plans, TVR developed a road version. Chairman Peter Wheeler drove it and judged it too much for the average driver, so the road model was cancelled, but one street-legal car was still completed and sold to a buyer Wheeler approved himself. The car was offered by Silverstone Auctions in May 2023.
