What do you do to make the fastest car in the world even better. You simply customize it if you can’t make it go any faster. That’s what Bugatti have done with the Bugatti Veyron 16.4 Grand Sport Vitesse 1 of 1. It will strictly be a limited edition and was unveiled in California. The car uses four turbochargers to increase the obscene power even more and decrease fuel consumption. The drive train has been improved for safer and better transmission and the 7-speed dual clutch transmission has benefited the most by this development. The Vitesse has 1200 horses powering the engine with a 0-100 time of 2.6 seconds. It has a top speed of 410 km/h with a special in-built safety feature to limit the speed to 375 km/h. This Bugatti has got a better all wheel drive, improved ESP and lighter 20-inch alloys. If you have the money, this is the car to buy.
