However the car got its name from the concept engine, first the vehicle TVR project 7/12 was appeared in 1996, this car attracts many crowds than any other car in the show. By the year 1998 the car was renamed TVR speed 12 resulting the 7.7 liter, 1000bhp and V12 engine with no of cylinders in the engine was very powerful, that it broke the TVR dyno. The much power and the expense cost was the main reason that only few cars were built and only five engines were created.
The car runs from 0-60mph in less than 3 sec, which was close to the McLaren F1, the car later become the fastest car on the road and naturally it was the fastest car in the world. The original intention of the car was to contest the GT1 motor sport. But unfortunately the speed 12 was sufficiently developed to win the race. However the races were restricted to 700bhp although the car engine was produced with the 800bhp, which was worked again later. The car weight up to 1000 kg with a 240mph (390km) with 0-60 mph in less than 2.9 second and cost up to £188,000 which was the most expensive car in the history.
In 2003 the project renamed the speed 12 which made an unusual step to sell TVR speed 12. The life of the TVR was not over; the revolutionary V12 motor with a 7.7 litre of is high tech engine and world’s most sleek car with such a powerful engine decided to focus on the speed 12 which stated to beat the speed of McLaren.
