The Bugatti Veyron Grand Sport Vitesse, which is probably the fastest and most powerful roadster in the world, gets yet another review from the British journalists. The 1,200 hp, 1.5 million GBP Veyron Vitesse is capable of reaching a top speed of 268 mph (431,072 km/h). Imagine doing this with the top down and the wind rushing through your hair. It must be quite an experience. However, you won't see this in this test drive, since Bugatti doesn't really allow top speed runs in their press cars.
