1,200 PS in a roadster — with the introduction of the Veyron 16.4 Grand Activity Vitesse in 2012 —  Bugatti set new requirements of electric power and efficiency from a roadster. A yr later on, the extraordinary hyper sports motor vehicle cemented its distinctive position in the automotive world by hitting a best speed of 408.84 km/h — developing by itself as the world’s most impressive and fastest manufacturing roadster — a file for open-leading vehicles that nonetheless stands now.

President of Bugatti Automobiles Christophe Piochon remembers how, following the Veyron 16.4 Tremendous Activity coupé introduced the entire world to the 1,200 PS W16 motor, prospects expressed their desire for an open-top version which boasted the exact same inconceivably large ability output. The engineers used the subsequent months acquiring the Veyron 16.4 Grand Sport Vitesse.

The best challenge when it arrived to the new roadster was obtaining enough driving balance and redefining the rollover defense and the removable roof of the predecessor Veyron 16.4 Grand Activity. The Veyron’s very specific structural structure desired to be even further strengthened. To accomplish this, a removable roof module made from light-weight polycarbonate was established, which designed open up-prime driving doable in just a several manual measures. What seems simple was in actuality anything but – in the coupé the roof is an integral portion of the monocoque body that can help provide the automobile with its superb security. In the roadster, reinforcements with really substantial torsional rigidity of 22,000 Nm per diploma along calculated load paths experienced to be added to obtain the vital rigidity and protection criteria.

The exceptionally sturdy and mild passenger compartment created in the monocoque structure needed an the best possible mix of body rigidity and light-weight development. If an integral portion of the structure — i.e. the roof — is removed, the load paths want to be redefined in order to sustain the vehicle’s large rigidity and crash protection that contain aspect impact and rollover protection.

The monocoque was for that reason bolstered all-around the aspect skirts and the transmission tunnel, and the B pillars were laterally stiffened by a carbon fiber support. A central carbon plate beneath the transmission tunnel served to ensure the automobile was much less susceptible to torsional flexing than any other roadster. In addition, the facet doors of the Veyron 16.4 Grand Sport Vitesse are produced from carbon fiber and disguise an integrated longitudinal assistance with pins that passes the load from the A pillar to the B pillar in the occasion of an accident, lowering impression force.

The 8.-liter W16 engine provides 1,200 PS and allows the Veyron 16.4 Grand Sport Vitesse to hit a best velocity of 410 km/h. On the report-setting push, done by Chinese businessman and race car driver Anthony Liu in 2013, a velocity of 408.84 km/h was recorded, with the roof down.

“Minus the roof, the Veyron 16.4 Grand Activity Vitesse demonstrates just how unparalleled Bugatti’s engineering knowledge is. Whilst the excess weight distribution is entirely distinctive when the roof is down, the car or truck stays stable and accelerates just as impressively as it does with the roof closed,” points out Christophe Piochon. “With the Veyron 16.4 Grand Sport Vitesse, Bugatti proved it was achievable to make an open up-best hyper sports car with incredibly significant efficiency and power output that drives really dynamically and very easily.”

The predecessor of the Veyron 16.4 Grand Sport Vitesse that was unveiled in 2008 — the Veyron 16.4 Grand Sport which boasted 1,001 PS — had already permitted customers to experience phenomenal energy with major-down driving, but the Veyron 16.4 Grand Sport Vitesse amplified the knowledge even even more, residing up to its identify — Vitesse — which interprets to speed. The boost of 199 PS when compared with the Veyron 16.4 Grand Activity was achieved 1st and foremost thanks to four greater turbochargers, with each other with new intercoolers.

The structure of the car was also overhauled the entrance of the Veyron 16.4 Grand Activity Vitesse capabilities huge air intakes as on the Veyron 16.4 Tremendous Sport. The bottom air slot extends sidewards into the wheel very well, providing the roadster an really commanding overall look. Straight beneath the air ingestion is a new front spoiler. A double diffuser, a central twin-pipe exhaust system, and a roof edge spoiler all blend to give the rear of the motor vehicle an very hanging style and design. In contrast to the coupé, the roadster’s pores and skin is manufactured solely from carbon. Bugatti therefore also features the selection of distinct, seen carbon paintwork.

Contrary to the Veyron 16.4 Super Activity, but like all the other Veyron types, the Veyron 16.4 Grand Activity Vitesse has two air scoops on each and every facet of the motor protect. In the roadster, these serve two reasons: firstly, they suck in air for the 16-cylinder engine and, secondly, they are an elegantly built-in aspect of the rollover defense.

Bugatti also strengthened all the powertrain elements, including the gearing of the 7-speed twin-clutch transmission (DSG). A gas technique taken from the Veyron 16.4 Super Activity that features a four-pump tank materials the engine with adequate gasoline. To reliably and easily set the electric power on the street, Bugatti retuned the chassis including ESP, tires, and brakes — all of which provide the roll and pitch down to an just about imperceptible minimal.

With the roof closed, the predecessor product, the Veyron 16.4 Grand Sport with 1,001 PS, hits a pace of just 407 km/h, matching that of the coupé. When the roof is down, Bugatti electronically curtails the speed to 360 km/h. In the Veyron 16.4 Grand Sport Vitesse, not only is the electrical power output higher, so way too is the leading speed. With its 1,200 PS when the roof is shut, the Veyron 16.4 Grand Sport Vitesse accelerates to as significantly as 410 km/h, when its velocity is limited to 375 km/h when the roof is down.

“The internal noise and turbulence are lowered to a minimum amount thanks to the roof edge spoiler and an elaborately created wind deflector. Even at top speeds of in excess of 200 km/h, the travellers can however maintain a dialogue with the best down,” relates Christophe Piochon. “This was us catering to a basic customer desire.” In addition to carbon, aluminum, and magnesium, Bugatti included a particular dampness-resistant leather-based with fine backstitching in the interior.

The Veyron 16.4 Grand Sport Vitesse was to be the last design in the Veyron series, with the 2013 edition established as portion of the Les Légendes de Bugatti range. Les Légendes de Bugatti celebrated not only 6 historical Bugatti individuals — Jean-Pierre Wimille, Jean Bugatti, Meo Costantini, Rembrandt Bugatti, Black Bess, and Ettore Bugatti — but also Bugatti’s exclusive creativeness and craftsmanship. To this finish, for the Les Légendes de Bugatti edition of the Veyron 16.4 Grand Activity Vitesse, the designers made use of finishing procedures and products never right before noticed like this in a vehicle. All the Légendes styles, which had been limited to just three autos each and every, marketed out straight away.
