Bugatti Veyron Grand Sport Vitesse unveiled at Geneva

Bugatti shows not just one, but two examples of the rarefied Grand Sport Vitesse at the 2012 Geneva Motor Show. Blue or more subtle grey, both make a massive impact.

Of course the 736kW (1,000hp) Bugatti Veyron was never really fast enough, so now those of you who are brave enough (and have the bank balance to match) can get one that is. Based upon the current open-top Grand Sport Veyron, it's the fastest Bug roadster yet.

Apart from the flame-grilled engine compartment? The 8.0-litre W12 multiple turbo-engine now punches out 883kW (1200hp), and the chassis has been developed to compliment the extra power. They say the steering is even sharper.

There's not much to beat this Veyron when it comes to Top Trumps, though steer clear of the economy stats. 0-100km/h in 2.5 seconds and a roof-up top speed of over 400km/h are the killers.
