By 1998 the car had been renamed the TVR Speed 12 and their GT1 racer was almost ready to go. TVR wanted to race at the [[24 Hours of Le Mans]], but that never happened. However, the Speed 12 GTS did manage to compete in a few races in the [[FIA GT Championship]] in the GT1 class, though sudden rule changes caused by advanced high-cost purpose built racers such as [[Porsche 911 GT1]], [[Nissan R390]] and [[Toyota GT-One]] and the subsequent demise of the class in other championships suddenly rendered the Speed 12 obsolete. In order that their work not go to waste, TVR immediately set about creating the road-going Speed 12, although the project would not be completed for another year.
Design-complete in 2000, the TVR Cerbera Speed 12, like its predecessor, never had a true measurement of engine power output officially taken, although the original engine (which produced 800 bhp) was employed yet again. The weight was kept down to 1000 kilograms and TVR reminded people that they were making a car that they thought would beat the McLaren F1 with the words "over 240 miles per hour" mentioned on several occasions. The new car would also be built in parallel with a new race car, although TVR were forced to opt for [[FIA GT2 class|GT2 class]] as the GT1 class had been dropped some years previous. The new race car managed to run for a few seasons in the [[British GT Championship]] and had some success, winning several races. It did however have problems with reliability, often leading to the car retiring from races. Meanwhile, the road car was almost ready and TVR had taken a good number of orders and deposits for it. With a price of £188,000 it would be the most expensive TVR in history.
The racing version of the engine produced approximately 675 bhp (503 kW) with its power limited by the intake restrictors required by racing regulations. For the road-version of the engine, the restrictors were not needed so the engine was developed without them.
In an interview then-owner [[Peter Wheeler]], said that TVR had tried to record the car's power on an engine dyno. The dyno was rated at 1,000 bhp (750 kW) but the test resulted in its input shaft being broken. To get an approximate figure TVR engineers tested each bank individually; the result was 480 bhp (360 kW) per bank, suggesting a total rating of 960 bhp (720 kW). Wheeler, no newcomer to high performance cars and an experienced racer in the [[TVR Tuscan Challenge]], drove one of the finished prototypes home and concluded that the car was unusable on the road, in his opinion simply too powerful.
The deposits were returned when the production plans were cancelled. The remaining prototypes were carted around to various car shows and one by one they were dismantled and used as spares for the Speed 12 race cars still competing in the British GT championship. The life of the Speed 12 was however, not yet over. In August 2003 TVR placed an advert in [[Auto Trader]] for a [[TVR Cerbera Speed 12]] registered '''W112 BHG'''. What TVR planned to do was to rebuild one of the prototypes and sell it on to an enthusiast. Buying the car was not a simple process however, and involved being personally met and vetted by Peter Wheeler himself to make sure the buyer was a suitable candidate for purchasing the car. Eventually, the deal was completed and the Speed 12 was rebuilt and handed over to its new owner. Since the original bodywork had been destroyed, TVR had to use a remaining shell from one of the GT racers, which proved a positive point as with the increased downforce the car would be even faster round a track than before.

The TVR Cerbera Speed 12, originally known as the Project 7/12, was a high performance concept car designed by TVR in 1997. Based in part on then-current TVR hardware, the vehicle was intended to be both the world's highest performance road car and the basis for a GT1 class endurance racer. However, problems during its development, changing GT1 class regulations and the eventual decision that it was simply incapable of being used as a road car ended the idea, forcing TVR executives to abandon its development.

The vehicle's engine, displacing 7.7 litres and having twelve cylinders, was reportedly capable of producing nearly one thousand horsepower, although an exact measurement was never made. Nonetheless, its performance was said to be astonishing, and it may have been capable of hitting sixty miles per hour in the low-three second range and have a top speed close to that of the McLaren F1.

By 1998 the car had been renamed the TVR Speed 12 and their GT1 racer was almost ready to go. TVR wanted to race at the 24 Hours of Le Mans, but that never happened. However, the Speed 12 GTS did manage to compete in a few races in the FIA GT Championship in the GT1 class, though sudden rule changes caused by advanced high-cost purpose built racers such as Porsche 911 GT1, Nissan R390 and Toyota GT-One and the subsequent demise of the class in other championships suddenly rendered the Speed 12 obsolete. In order that their work not go to waste, TVR immediately set about creating the road-going Speed 12, although the project would not be completed for another year.

Design-complete in 2000, the TVR Cerbera Speed 12, like its predecessor, never had a true measurement of engine power output officially taken, although the original engine (which produced 800 bhp) was employed yet again. The weight was kept down to 1000 kilograms and TVR reminded people that they were making a car that they thought would beat the McLaren F1 with the words "over 240 miles per hour" mentioned on several occasions. The new car would also be built in parallel with a new race car, although TVR were forced to opt for GT2 class as the GT1 class had been dropped some years previous. The new race car managed to run for a few seasons in the British GT Championship and had some success, winning several races. It did however have problems with reliability, often leading to the car retiring from races. Meanwhile, the road car was almost ready and TVR had taken a good number of orders and deposits for it. With a price of £188,000 it would be the most expensive TVR in history.

The racing version of the engine produced approximately 675 bhp (503 kW) with its power limited by the intake restrictors required by racing regulations. For the road-version of the engine, the restrictors were not needed so the engine was developed without them.

In an interview then-owner Peter Wheeler, said that TVR had tried to record the car's power on an engine dyno. The dyno was rated at 1,000 bhp (750 kW) but the test resulted in its input shaft being broken. To get an approximate figure TVR engineers tested each bank individually; the result was 480 bhp (360 kW) per bank, suggesting a total rating of 960 bhp (720 kW). Wheeler, no newcomer to high performance cars and an experienced racer in the TVR Tuscan Challenge, drove one of the finished prototypes home and concluded that the car was unusable on the road, in his opinion simply too powerful.
