TVR Cerbera Speed 12
TVR Cerbera Speed 12
The TVR Cerbera Speed 12, originally known as Project 7/12, was a high-performance concept car, which was designed in 1997 by TVR in Blackpool ( England). The car was based in part on the then production vehicles from TVR and should include both the most powerful road car in the world as well as the basis for a GT1 racing cars. But problems during development, changing the rules for the GT1 class and the eventual realization that the vehicle could not be used on the road, the idea put an end to and the management of TVR ceased development.
The Speed Twelve engine of the vehicle had 7.7 liters, twelve cylinders and nearly 1,000 horsepower should have developed ( 735 kW). An accurate power measurement, however, was never carried out. However, should its power development have been impressive and he would have the car in just over 3 s accelerates from 0-100 km / h and higher maximum speed would come close to the McLaren F1.
History
Concept Vehicle Project 7/12
The car that 7/12 was known as TVR Project, first appeared in 1996 at the Birmingham Motor Show and dominated there, as it attracted more visitors than other cars. The number 7 indicates a machine with 7 liter displacement toward (although there were actually yes 7.7 l ) and the number 12 to the number of cylinders. TVR announced that the engine has 800 hp ( 588 kW) would develop performance and faster than the McLaren F1 was; the first concept vehicles aimed at the FIA GT1 class in the form valid at that time. The cars had to be throttled back to more modest 660 hp ( 485 kW), but the weight of about 1000 kg would be preserved. The street version would just weighed a lot, but without the limiter, the power would have increased considerably: TVR verlautbarte, there were 800 hp ( 588 kW), but there was no reliable measurement. The car had a designed especially for him six-speed gearbox and a clutch. The Speed Twelve engine consisted of two Speed Six engines, which were brought together on a crankshaft. Unlike other such automotive engine block was not made of cast iron or aluminum, but from steel.
Speed 12
In 1998, the car was renamed the TVR Speed 12 and the GT1 race version was almost finished. TVR wanted to call the car at the 24 Hours of Le Mans, but this never came to fruition. But the Speed 12 GTS entered into several races of the FIA GT Championship in the GT1 class, though sudden rule changes by extremely expensive racing machines, such as the Porsche 911 GT1, Nissan R390 and the Toyota GT -One, and the subsequent task the class in the other championships speed 12 made redundant. Thus, the work was not entirely in vain, TVR This project, however, took care immediately to a street version of the Speed 12 could not be completed within one year.
The TVR Cerbera Speed 12, which was completed in 2000, was - like its predecessor - never subjected to a power measurement, but they built the original machine (which is said to have developed 800 bhp ) again. The vehicle weight remained at low 1000 kg and TVR reminded his employees because they were going to build a car that would beat the McLaren F1 by " over 240 mph ( 384 km / h ) " used the words on several occasions. The new car should also occur in parallel with a new race car, with TVR had to decide for the GT2 class, since the GT1 class had been abandoned some years before. The new racing car launched some years in the British GT Championship and was able to celebrate many successes and win some races. But there were several problems with its reliability, which often forced the car to the task. In the meantime, the road version was almost finished and TVR had received a large number of orders and payments for it. With a price tag of £ 188,000, - it was the most expensive car in the TVR history.
The racing version of the engine delivered about 675 hp ( 496 kW), the power was curtailed by Einlassbegrenzer, which prescribed the racing regulations. For the road version of this limiter were not necessary and so they developed the machine without it.
In an interview, the then owner Peter Wheeler, TVR would have attempted to determine the engine power with the help of a dynamometer. The dynamometer was suitable for up to 1,000 hp ( 735 kW), but the attempt ended with the rupture of the input shaft. To get an approximate value, the TVR engineers tested each of the two cylinder banks separately and arrived at a value of 480 hp ( 353 kW) per bank, suggesting an overall power of the engine of 960 hp ( 706 kW). Wheeler, who was not a novice in the field of high-performance vehicles and an experienced racer in the company's TVR Tuscan Challenge, drove one of the finished prototypes home and came to the conclusion that the car was unfit for the road, because he feels he simply had too much power.
TVR returned the payments and the plans for mass production were set aside. The remaining prototypes were shown around to different car shows and then dismantled piece by piece and the parts for the Speed 12 race cars used, which still ran in the British GT Championship. However, the lifetime of the Speed 12 was not over yet. In August 2003, TVR turned an ad for a TVR Cerbera Speed 12 for the registration number W112 BHG in the Auto Trader. TVR wanted to build one of the prototypes back and sell it to an enthusiast. However, the purchase was said to be not a simple matter; the buyer is Peter Wheeler have met in person and have been checked by him, whether he would be a suitable buyer. Finally, the transaction was completed, the Speed 12 was rebuilt and handed over to the new owner. Since the original body had been destroyed, TVR had the body of the GT race car use, which had the advantage that the car was even faster than before with the additional output. In addition, revised TVR engine and ECU. The car appeared in the May 2005 issue of Evo magazine, where he was described as " awesome " and " awful fast."
