WORLDS FASTEST CAR

BUGGATI VYRON

March 3, 2009 A new Bugatti goes on sale this week, and like every other automobile to ever bear the revered name, it's so over-the-top you can't help but admire the audacious spirit which permeates all aspects of its engineering. The limited edition open-top Bugatti Veyron 16.4 Grand Sport will be the world's fastest open top car, capable of travelling at 360 km/h with the roof off, and 407 km/h with it closed. Just 150 will be made of the EUR 1.4 million Grand Sport with the first 40 reserved for existing Bugatti customers. The usual cut-no-corners approach has seen the original Veyron virtually reengineered to accommodate the lack of the roof as a structural component.

When the roof is closed, the Bugatti Veyron 16.4 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. The world’s fastest roadster is immediately recognizable from its roofed brethren by its slightly higher windscreen, stylized daytime running lights, and lightweight, transparent polycarbonate roof.

The main challenge in developing the new Bugatti Veyron 16.4 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
