For the all-carbon fiber Grand Sport Vitesse, Bugatti developed a new roof spoiler that drastically cuts down on the wind noise and buffeting in the interior, a pretty important element considering the car is a convertible. In addition, Bugatti also installed a windbreak that owners can just as easily stow away compactly in the luggage compartment when not in use.
As a Grand Sport with the soul of a Super Sport, the Vitesse also gets the benefit of getting some transplanted aerodynamic components from its SS brother, particularly at the front with the larger air intakes just between the radiator grille. There’s also the presence of a new bottom air vent that stretches sideways into the wheel housing. Just below it, there’s a refined front spoiler that has been designed in a similar way to the splitters used in motor racing. The xenon headlights on the Grand Sport Vitesse are also a new addition, something that was also taken from the Super Sport.
Over at the back, the Veyron Vitesse gets even more Super Sport-like, courtesy of a double diffusor and a centrally positioned twin tailpipe. The car also has two redesigned air scoops on the left and right of the engine cover, fulfilling the purpose of pulling in air for the engine, as well as being an elegantly integrated part of the anti-roll protection system.
Think of it as a Veyron Grand Sport in skin and Veyron Super Sport in heart. According to Bugatti, there’s a reason why the model is considered the most powerful serial produced convertible in the world: underneath that convertible body lies an additional four enlarged turbochargers and intercoolers to aid the Grand Sport’s monstrous 7.9-liter 16-cylinder engine in producing an output of 1,200 horsepower and 1,106 lb/ft of torque, a substantial spike from the model’s otherwise erstwhile 1,001 horsepower and 922 lb/ft of torque figures.
That increase in output is largely attributed to the aforementioned four larger turbochargers with intercoolers, but that’s not the entire equation. In order to safely transfer the immense forces that came as a result of the added power, Bugatti extensively reinforced all drivetrain components, particularly the seven-speed dual-clutch gearbox (DSG), which has been adapted to the new requirements. As a matter of consequence of the larger turbochargers and the overall reduced back pressure, Bugatti managed to fit a four-pump tank - the same one used in the Super Sport - to reduce the fuel consumption slightly despite the increased output.
All told, the Grand Sport Vitesse is capable of hitting 0-62 mph in just 2.6 seconds while achieving a top speed of 255 mph on closed tracks, fully stamping its designation as the fastest production roadster ever. As far as "road" speeds are concerned, the Veyron Grand Sport Vitesse "only" does 223 mph.
