Bugatti Veyron Grand Sport, 2009


The significant modifications have been made to the vehicle's complex structure to make possible open-top driving, thereby adding a new dimension to this high-performance sports car. Incorporating a host of new and innovative safety and equipment features, it is the world's fastest and most exciting roadster. It is immediately recognizable as a result of its slightly higher windscreen, stylized daytime running lights, and lightweight, transparent polycarbonate roof.

The main challenge in developing the new Bugatti Veyron Grand Sport with removable roof resulted from the unique structure of the fixed-roof Bugatti Veyron. An optimum combination of rigidity and lightweight engineering ensures the monocoque passenger cell of the original model is extremely strong while weighing an absolute minimum - it is a central element of the vehicle's structure. As the roof is an integral part of this, removing it meant the load paths had to be completely redesigned to maintain the vehicle's rigidity and crash safety, and to offer additional protection from side impacts and rolling.

The monocoque structure has been reinforced around the side skirts and the transmission tunnel. The B-pillars have been cross-stiffened using a carbon fibre support, and a central carbon plate has been positioned beneath the transmission tunnel to ensure the vehicle suffers from less torsional flexing than any other roadster.

The doors of the new Bugatti Veyron Grand Sport are made of carbon fibre, and house an integrated longitudinal beam.

In the event of an accident, this transfers the load from the A to the B-pillar, thereby dissipating impact energy. Furthermore, the two redesigned air intakes for the 16-cylinder mid-engine now feature 10-centimetre wide carbon-fibre elements to offer protection should the car roll.

With moisture-resistant, backstitched leather, a range of new equipment features has been added to the interior, including a reversing camera with 2.7-inch monitor in the rear-view-mirror, and the "Puccini" sound system with digital signal processor.

When the roof is closed, 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 time. When this folding roof is in place, the car can travel at up to 130 km/h.
