Bugatti Veyron 16 4 Grand Sport Vitesse 2013 Review

The Bugatti Veyron 16.4 Grand Sport Vitesse 2013 is the carmaker's ultimate goal of bringing the achievements of the Super Sport on the convertible, making it the fastest car of its class in the world. Evidently a top down version of the Super Sport requires quite a lot of thinking and engineering, but Bugatti is no stranger to the concept of breaking the limits and exceeding expectations.

The convertible is motivated by the 9.0 liter W16 engine that delivers no more or less than 1200 horsepower at 6400 RPM, and an astonishing 1106 lb-ft of torque from 3000 to 5000 RPM. Evidently the Grand Sport shares a lot of other components with the Super Sportincluding the four bigger turbochargers, the intercooler and the quad fuel pump setup just to name a few.

In terms of performance I believe there's no mystery here. The Grand Sport goes from 0 to 60 mph in under 2.6 seconds, from a standstill to 124 mph in only 7.1 seconds and from 0 to 186 in 16 seconds. So what about the top speed? The Grand Sport can go up to 255 mph, but there's a bit of a catch. Evidently the roof needs to be on in order to achieve that top speed, because with the roof down the aerodynamics change and it affects how the supercar performs on the road. That being said, Bugatti had to implement a few changes when the roof is off. For instance, the rear wing knows when the hardtop has been detached and it changes its angle in order to increase downforce and aerodynamics. They also had to limit the car's top speed while in convertible mode to 233 mph.

Evidently in order to achieve this kind of performance you need to burn quite a lot of fuel and I'm pretty sure that whoever intends on purchasing a Grand Sport will not consider fuel efficiency while doing so, but just to give you an idea of how extreme this piece of engineering is, at full throttle the 8 liter W16 will burn it's entire tank of 26.4 gallons of gas in eight minutes and will gulp more air in one hour than a human being in one month.

As is tradition, the Grand Sport has built with no compromise and you still get the same level of luxury found in the previous models. It's a civilized sports car and offers a nice place to sit in. Everything seems perfect and from the moment you fire up the engine to the part where you put your foot down on the carbon-ceramic brakes, the Vitesse manages to impress quite a bit more than the one-trick-pony supercars we're used, such asLamborghinis and Ferraris.

However, it all comes at a price and the Bugatti Veyron 16.4 Grand Sport Vitesse 2013 manages to impress even with its estimated base price of $2.5 million, which seems as out of this world as the car itself.

Molsheim / El Vendrell – June 2012 – Following the success of the Bugatti Veyron 16.4 Super Sport, Bugatti did not have to wait long before it received the first inquiries about an open-top version of the Grand Sport that could also deliver 882 kW (1,200 hp). “We were instantly electrified by the idea of transferring the power of the Super Sport to the Grand Sport, which previously delivered a maximum of 1,001 hp, and thus taking the roadster to a new level,” says Wolfgang Dürheimer. The President of Bugatti Automobiles S.A.S. continues: “Our team has managed to transfer the world’s most powerful car engine to the open-top sports car while taking all vehicle dynamics and aerodynamic parameters into consideration. We are proud to present the 1,200 hp Bugatti Veyron 16.4 Grand Sport Vitesse, the fastest roadster ever to a selected group of media on the challenging mountain roads of Catalonia and the high speed circuit of IDIADA in Santa Oliva, Spain.

Dynamics in numbers. 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 reach 100 km/h (62 mph) from standing in unbelievable 2.6 seconds. The top speed of 410 km/h (255 mph) makes the four-wheel drive Vitesse the fastest production roadster ever. The maximum speed is reached on closed tracks with special safety precautions. In “normal” handling mode, the Vitesse is electronically limited to 375 km/h (233 mph).
Optimized drive system. The 199 hp increase over the Grand Sport has been mainly achieved by using four larger turbochargers with new intercoolers. Furthermore, Bugatti has extensively reinforced all drivetrain components in order to safely transfer the immense forces at all times. The gearing of the seven-speed dual-clutch gearbox (DSG) in particular has been adapted to the new requirements. In this context, as on the Super Sport, Bugatti has also modified the air ducting in the area of the drivetrain. 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.
The fuel system, with a four-pump tank, has been taken from the Super Sport. Chassis. In order to put the unrivalled power onto the road absolutely 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. Body roll and pitching during hard acceleration and braking are now virtually imperceptible. Optimised wheel-load fluctuations have further reduced understeer and allow a maximum level of active safety. In addition to the incomparable lateral acceleration of up to 1.4 g, the precise interaction of the tires (on all-new, lighter 20-inch “Vitesse”-type alloy wheels), together with the intelligent all-wheel-drive system, ensures extremely good handling. The chassis, all-wheeldrive
system and the revised ESP form a dynamic alliance: since the reconfigured ESP kicks in
slightly later, for example when you accelerate out of corners, the Vitesse also provides a more dynamic performance in these situations. It goes without saying that Bugatti has adapted the brakecooling 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.
In general, it can be said that the Vitesse is even sportier than the 1,001 hp Grand Sport, but at the same time it has not been turned into a full-blown racing car. It therefore remains easy to master for the driver. In this context, it is simply astounding that Bugatti managed to increase comfort in the chassis area by reducing the dynamic natural frequency.
Body. Bugatti has developed a new roof spoiler for the 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 200 km/h (124 mph).
Numerous aerodynamic measures at the front and rear that appeared on the Super Sport have been adapted for the Vitesse. The front end is therefore characterised 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 improved xenon headlights from the Super Sport, which are now framed in black, are also new. The rear end, which is also derived from the Super Sport, is characterised by a double diffusor and a centrally positioned twin tailpipe. A new Park Distance Control system (PDC) watches over the front and the rear.
The two air scoops on the left and right of the engine cover (redesigned for the Vitesse) are a characteristic of the Grand Sport and thus also of the Vitesse. These air scoops fulfil two tasks on the roadster. On the one hand, they pull in air for the engine, and on the other, they are an elegantly integrated part of the anti-roll protection system. As on the Super Sport, a full-carbon-fibre monocoque, which allows an extremely high torsional rigidity combined with maximum passive safety, is also used on the Vitesse. The outer skin is also made completely from carbon fibre and, consequently, the new Bugatti Veyron 16.4 Grand Sport Vitesse is available in clear-coated visible carbon.
Interior. Carbon fibre is (along with stainless metals such as Aluminium and Magnesium) also the dominant material in the interior of the 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-color black trim parts (for example, in the roof console) are also new in the Grand Sport version, as is a special seat design for the Vitesse. The twotone leather seat covers are enhanced by contrasting stitching between the seat base and the side sections. Contrasting stitching is also featured on the leather armrest between the seats, which
comes without the typical quilting. Also new: knee pads in the centre tunnel area, an additional 12V socket (in the glove compartment), the restraint systems, the illuminated start and parking lock button (same as Super Sport), an instrument cluster with shift-up information and – as a matter of honour – the power gauge that now goes up to 1,200 hp!
The Bugatti brand has originally been founded in 1909 by the educated artist and engineer Ettore Bugatti. His cars were well known for the beauty of their designs, their lightness and advanced technology. In the 1920s and 30s they won more races than any of their competitors. Closed down in 1957 the company was bought and revived by the Volkswagen Group in 1998. The first Bugatti Veyron 16.4 was produced in 2005, the final of the series, limited to 300 units was sold in June 2011. At the moment the brand offers the 1,001 hp roadster Grand Sport and its stronger brother the 1,200 hp roadster Vitesse limited to 150 units combined, of which so far 69 have been ordered.
