Bugatti has presented the most powerful roadster ever at the 2012 Geneva Motor Show.
The new Bugatti Veyron 16.4 Grand Sport Vitesse boasts a remarkable maximum torque of 1,500 Nm (at 3,000-5,000 rpm) from the 7.9-litre capacity of its W16 engine. The maximum output (1,200 hp) is reached at 6,400 rpm. These figures allow the car to accelerate from 0-62 mph from standing in 2.6 seconds. The top speed of 255 mph makes the four-wheel drive Grand Sport Vitesse the fastest production roadster ever.
The 199 hp increase over the Grand Sport model has been achieved by using four larger turbochargers with new intercoolers. Bugatti has extensively reinforced all drivetrain components in order to safely transfer the immense forces at all times. As a consequence of the larger turbochargers and the overall reduced back pressure, it was even possible to reduce the fuel consumption slightly despite the increased output.
In order to put the unrivalled power onto the road safely and masterfully, the engineers have reconfigured the chassis of the Vitesse. Thanks to the quick-responding dampers that have been adapted from motor racing, the control of the vehicle has been further improved and perfectly balanced. In addition to the incomparable lateral acceleration of up to 1.4 g, the precise interaction of the tyres (on all-new, lighter 20-inch “Vitesse”-type alloy wheels), together with the intelligent all-wheeldrive system, ensures extremely good handling. Since the reconfigured ESP kicks in slightly later, for example when you accelerate out of corners, the Grand Sport Vitesse also provides a more dynamic
performance in these situations. It goes without saying that Bugatti has adapted the brake-cooling system to account for the even higher engine output. The brakes, which are unparalleled in terms of stability and performance, now have additional and larger air intakes.
Bugatti has developed a new roof spoiler for the Grand Sport Vitesse that significantly reduces wind noise and buffeting in the interior. Furthermore, there will be a new windbreak for the roadster that can be stored away compactly in the luggage compartment when not in use.
Both details will also be available for the Grand Sport. Together, they allow extremely relaxed, open-top driving even at speeds of around 124 mph.
Numerous aerodynamic measures at the front and rear that appeared on the Super Sport have been adapted for the Grand Sport Vitesse. The front end is characterized by larger air intakes; the two central air intakes to the left and right of the Bugatti radiator grille are divided horizontally by a bar.
The bottom air vent stretches sideways into the wheel housing and gives this exceptional sports car an extremely masterful appearance. Immediately below this air intake, you will see a new, visually refined front spoiler that has been designed in a similar way to the splitters used in motor racing. The rear end, which is also derived from the Super Sport, is characterised by a double diffuser and a centrally positioned twin tailpipe.
Carbon fibre is (along with stainless metals such as Aluminium and Magnesium) also the
dominant material in the interior of the Grand Sport Vitesse. Numerous interior parts are now made from carbon fibre in the 1,200 hp roadster. This includes the centre console extension, a cover with EB logo in the rear-bulkhead leather trim (between the seat backrests) and the belt outlet covers on the seats. The décor on the centre console, the door inserts and the adjoining trim on the instrument panel are also made from carbon fibre. The bi-colour black trim parts are also new in the Grand Sport version, and so is a special seat design for the Grand Sport Vitesse.Published 6 March 2012
