TVR Cerbera Speed 12 Prototype
The TVR Cerbera Speed 12 remains one of the most notorious and extreme supercars ever conceived. Originally developed for GT1 racing, the Speed 12 featured a monstrous 7.7-liter V12 (essentially two Speed Six straight-sixes joined) producing approximately 800 horsepower in a car weighing barely over 2,200 pounds. The result was performance so extreme that TVR's Peter Wheeler famously declared it 'unusable' on public roads. During testing, Wheeler himself struggled to control the car and subsequently cancelled the production run despite several customers having placed deposits. Only three examples were built: the original race car and two road-going prototypes. One customer car eventually sold to a private buyer. The Speed 12's legend grew from its sheer brutality, uncompromising specification, and the fact that it was deemed too dangerous to sell. With no traction control, ABS, or driver aids of any kind, this represented British automotive extremism at its absolute zenith.
Only one privately-owned example exists globally, making this purely theoretical. If one ever came to market, expect multi-million pound valuation. The single owner-occupied Speed 12 is unlikely ever to be sold. The other surviving examples are either in museums or private collections. This represents one of the rarest and most extreme collectible cars in existence.
