Bugatti Veyron 16.4 Grand Sport was unveiled at Pebble Beach Concours d'Elegance in 2008. The first Bugatti Veyron 16.4 Grand Sport (chassis 001) was sold at auction for charity. Significant modifications have been made to this expensive vehicle's complex construction to make possible open-top driving, thereby adding a new dimension to this super sports car.
The main difficulty in developing the new Bugatti Veyron Grand Sport with removable roof resulted from the unique structure of the fixed-roof Bugatti Veyron. An excellent blend of rigidity and lightweight engineering guarantees the monocoque passenger cell of the original model is extremely strong.
As the roof is an indivisible part of this, removing it meant the load paths had to be fully redesigned to maintain the vehicle's rigidity and car safety, and to offer additional protection from side impacts and rolling. As a result, the monocoque formation has been strengthened around the side skirts and the transmission tunnel. The B-pillars have been cross-stiffened adopting a carbon fibre support, and a central carbon base has been placed beneath the transmission tunnel to ensure the vehicle experiences from less torsional flexing than any other roadster.
When the roof is secured, the Bugatti Veyron Grand Sport can reach 407 km/h, while speeds of up to 360 km/h are possible with roof off. Should it rain, an innovative folding roof stored in the luggage compartment can be opened up like an umbrella at any moment. When this folding roof is in place, the car can travel at up to 130 km/h.
Assembled by hand at the company's headquarters in Molsheim, Alsace, the Bugatti Veyron Grand Sport will be available from March 2009 at the price of 1.4 million euros (excluding tax). Just 150 examples will be made, with the first 50 of these going exclusively to registered Bugatti customers. The first vehicle is certain to be highly sought after, and Bugatti has taken the decision to donate this specific car to charity. It will be sold to the highest bidder at the Pebble Beach Auction presented by Gooding & Company.
