When you pull up to the stop light with a Veyron there are two words that you need to say : 1001 horsepower. 

The Grand Sport specifically differs from the regular super car the Veyron because it is a roadster: meaning an open air performance experience. Bugatti's calls the Veyron 16.4 Grand Sport "the world's fastest and exciting roadster."This statement is backed up by a top speed of over 200 mph at 224.

   
Bugatti has official revealed the new Bugatti Veyron 16.4 Grand Sport - the open-top, convertible, targa top or whatever you want to call it Veyron. Bugatti didn’t just pull the roof off the Veyron coupe - engineers made a few changes to create the world’s fastest roadster.

The Bugatti Veyron 16.4 Grand Sport has a slightly higher windscreen, re-styled daytime running lights and a lightweight transparent polycarbonate roof. It was the removable roof that was the main challenge for engineers. The monocoque structure has been strengthened around the side-skirts along with a stiffened B-pillars using carbon fiber support. The interior features moisture-resistant backstitched leather with some new features such as a reversing camera with a 2.7-inch monitor in the rear-view-mirror and the Puccini sound system.

Power comes from the W16 1001 horsepower engine that allows for a top speed of 253mph with the top closed and 190mph with the roof off. With the folding roof in place top speed is limited to a very low 81mph.

Bugatti will produce only 150 units of the Veyron 16.4 Grand Sport - 50 of which are already going to registered Bugatti customers. The first unit will be sold to at the Pebble Beach Auction with the proceeds going to charity.

Words on the supercar from Bugatti's pilot official:

"When I had the chance to test-drive the new Grand Sport for the first time myself, I was filled with excitement", said Pierre Henri Raphanel, Bugatti's Pilot official, "as soon I shifted into second gear, I knew this was a completely different car. I could immediately feel the difference. Even with the roof still on, in the tips of my fingers and at the base of my spine everything was more present, more intimate. More precise with less understeer, almost as if you had taken away some filters from the suspension and the steering." The former Le Mans winner has probably driven more kilometres in a Veyron than anyone else, presenting the car to numerous customers and the press. Taking off the roof "the excitement comes directly from the engine – giving you the feeling that you had a horsepower factory just thirty centimetres behind your head, trying to suck you up and swallow you," he raves.

The Bugatti Veyron 16.4 Grand Sport is limited to a production run of 150 units.
