The TVR Cerbera Speed Twelve made its world debut at the London Motor Show in October 1999 and is a departure from the traditional TVR manufacturing methods.
With its hybrid aluminium honeycomb and tubular steel chassis, carbon fibre bodywork, six speed sequential gearbox and unique fabricated steel blocked V12 800 bhp powerplant, this sensational lightweight variation of the Cerbera theme is in the tradition of week-end race cars that can be driven to and from the track.
The car inherits more than just the engine and therefore name of its GT1 predecessor.
With the recent demise of GT1, TVR has taken the opportunity to develop a new GT2 contender that will take TVR back onto the global GT stage.
International GT rules mandate a flat floor and a tubular steel roll cage and so the primary chassis of the car consists of a T45 steel tubular safety cell which is integrally braced by the flat aluminium honeycomb floor and bulkheads.
This hybrid construction both follows the racing rules and allows for the car to be quite simple to assemble.
The front bulkhead is immediately behind the engine whilst the rear one lies directly ahead of the rear wheels. This allows the exhausts to exit cleanly away from the engine and then turn ahead of the footwell to run down the sills, and the driver to sit as far rearward as possible.
The removal of the previous structural reliance upon the tunnel allows this to be as narrow as the gearbox dictates and in turn allows the driver to be positioned further inboard towards the centreline of the car.
The honeycomb floor and bulkheads are stiff enough to accept the seat mounts and pedal assemblies directly without need for further reinforcement.
The floors are stabilised at their outer edges where they are folded up 90.
