The TVR Speed 12 was a limited production supercar introduced for the 1997 model year. The Speed 12, which is also known as the Cerbera Speed 12, was designed to be the fastest production car ever made, with its naturally aspirated 7.7L V12 engine capable of producing 800HP. This engine was created by combining two straight 6’s from the TVR Cerbera upon which the Speed 12 was based. The car never went on full production, given that it was too dangerous for clients to be driving on public roads. Only 3 Speed 12’s were ever manufactured, making it the most special TVR in existence.
