The Bugatti Veyron 16.4 Grand Sport is the open top version of the Bugatti Veyron. The Veyron Grand Sport was unveiled at the 2008 Pebble Beach Concours d'Elegance in Monterey, California.

In order that the Bugatti Veyron Grand Sport has the same performance and safety standards as the hard top variant, significant modifications were made to the vehicle's complex structure. Some of the new features include a slightly higher windscreen, stylized daytime running lights, and a lightweight, transparent polycarbonate roof.

The main challenge in developing the Bugatti Veyron 16.4 Grand Sport was keeping the chassis rigidity and strength at the same level as the fixed-roof model. 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.

As a result, the monocoque structure has been reinforced around the side skirts and the transmission tunnel. The B-pillars have been cross-stiffened using a carbon fiber 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 Bugatti Veyron 16.4 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 8.0 litre, quad-turbo, 16-cylinder mid-mounted engine now feature 10-centimetre wide carbon-fibre elements to offer rollover protection for the occupants.

Along with moisture-resistant, backstitched leather, a range of new equipment features has been added to the Grand Sport's 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 16.4 Grand Sport can reach 252 mph (407 km/h), while speeds of up to 224 mph (360 km/h) are possible with the roof panel removed. Should it rain, and the polycarbonate roof is elsewhere, a temporary 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 Veyron Grand Sport's top speed is a lowly 81 mph (130 km/h).

In total only 150 examples of the Bugatti Veyron Grand Sport will be produced, with the first 50 of these going exclusively to registered Bugatti customers.
