Ten Years of the Bugatti Veyron 16.4 Grand Sport Vitesse — The World’s Fastest Roadster

1,200 PS in a roadster — with the introduction of the Veyron 16.4 Grand Activity Vitesse in 2012 —  Bugatti set new expectations of electricity and functionality from a roadster. A year afterwards, the extraordinary hyper athletics auto cemented its special status in the automotive environment by hitting a top pace of 408.84 km/h — developing itself as the world’s most powerful and swiftest production roadster — a report for open-prime cars that continue to stands nowadays.

President of Bugatti Automobiles Christophe Piochon remembers how, following the Veyron 16.4 Tremendous Sport coupé released the planet to the 1,200 PS W16 engine, shoppers expressed their motivation for an open up-prime variation which boasted the very same inconceivably higher electric power output. The engineers invested the subsequent months building the Veyron 16.4 Grand Activity Vitesse.

The greatest problem when it came to the new roadster was accomplishing adequate driving security and redefining the rollover defense and the detachable roof of the predecessor Veyron 16.4 Grand Activity. The Veyron’s extremely distinct structural design and style wanted to be more strengthened. To attain this, a detachable roof module produced from lightweight polycarbonate was made, which created open up-top driving doable in just a couple manual methods. What appears easy was in actuality everything but — in the coupé the roof is an integral portion of the monocoque frame that aids present the automobile with its fantastic steadiness. In the roadster, reinforcements with really large torsional rigidity of 22,000 Nm per diploma alongside calculated load paths had to be additional to attain the vital rigidity and basic safety criteria.

The extremely sturdy and light-weight passenger compartment designed in the monocoque style and design required an optimum mix of physique rigidity and lightweight construction. If an integral element of the construction — i.e. the roof — is eliminated, the load paths will need to be redefined in buy to retain the vehicle’s high rigidity and crash safety that include things like aspect effect and rollover protection.

The monocoque was as a result bolstered all around the facet skirts and the transmission tunnel, and the B pillars were being laterally stiffened by a carbon fibre support. A central carbon plate beneath the transmission tunnel served to be certain the car or truck was significantly less prone to torsional flexing than any other roadster. In addition, the facet doors of the Veyron 16.4 Grand Activity Vitesse are designed from carbon fibre and disguise an integrated longitudinal support with pins that passes the load from the A pillar to the B pillar in the party of an accident, lessening affect drive.

The 8.-litre W16 engine delivers 1,200 PS and enables the Veyron 16.4 Grand Sport Vitesse to strike a major speed of 410 km/h. On the file-environment drive, carried out by Chinese businessman and race automobile 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 Sport Vitesse demonstrates just how unparalleled Bugatti’s engineering abilities is. While the body weight distribution is totally distinctive when the roof is down, the car or truck continues to be stable and accelerates just as impressively as it does with the roof closed,” describes Christophe Piochon. “With the Veyron 16.4 Grand Sport Vitesse, Bugatti proved it was attainable to establish an open-top rated hyper sports motor vehicle with pretty large overall performance and electricity output that drives exceptionally dynamically and incredibly easily.”

The predecessor of the Veyron 16.4 Grand Activity Vitesse that was unveiled in 2008 — the Veyron 16.4 Grand Sport which boasted 1,001 PS — experienced by now allowed consumers to expertise phenomenal power with best-down driving, but the Veyron 16.4 Grand Sport Vitesse amplified the working experience even even further, residing up to its identify — Vitesse — which interprets to pace. The boost of 199 PS in contrast with the Veyron 16.4 Grand Activity was achieved very first and foremost many thanks to 4 larger sized turbochargers, with each other with new intercoolers.

The structure of the motor vehicle was also overhauled the entrance of the Veyron 16.4 Grand Sport Vitesse capabilities wide air intakes as on the Veyron 16.4 Super Activity. The base air slot extends sidewards into the wheel perfectly, offering the roadster an incredibly commanding look. Right beneath the air consumption is a new front spoiler. A double diffuser, a central twin-pipe exhaust program, and a roof edge spoiler all mix to give the rear of the car an very placing design and style. In contrast to the coupé, the roadster’s pores and skin is produced fully from carbon. Bugatti therefore also provides the selection of distinct, seen carbon paintwork.

In contrast to the Veyron 16.4 Super Sport, but like all the other Veyron styles, 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 uses: to start with, they suck in air for the 16-cylinder engine and, secondly, they are an elegantly integrated component of the rollover defense.

Bugatti also strengthened all the powertrain elements, like the gearing of the seven-pace twin-clutch transmission (DSG). A fuel process taken from the Veyron 16.4 Super Sport that characteristics a four-pump tank materials the engine with sufficient fuel. To reliably and easily set the ability on the street, Bugatti retuned the chassis like ESP, tires, and brakes — all of which carry the roll and pitch down to an pretty much imperceptible minimum.

With the roof shut, the predecessor design, the Veyron 16.4 Grand Activity with 1,001 PS, hits a pace of particularly 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 Activity Vitesse, not only is the electricity output higher, so far too is the top rated velocity. With its 1,200 PS when the roof is shut, the Veyron 16.4 Grand Sport Vitesse accelerates to as considerably as 410 km/h, although its speed is constrained to 375 km/h when the roof is down.

“The interior sound and turbulence are lessened to a least thanks to the roof edge spoiler and an elaborately developed wind deflector. Even at prime speeds of around 200 km/h, the travellers can still keep a dialogue with the major down,” relates Christophe Piochon. “This was us catering to a essential shopper want.” In addition to carbon, aluminum, and magnesium, Bugatti included a unique moisture-resistant leather-based with great backstitching in the inside.

The Veyron 16.4 Grand Activity Vitesse was to be the previous design in the Veyron sequence, with the 2013 version made as aspect 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 special creative imagination and craftsmanship. To this conclusion, for the Les Légendes de Bugatti edition of the Veyron 16.4 Grand Activity Vitesse, the designers used finishing techniques and supplies in no way ahead of noticed like this in a car. All the Légendes designs, which have been confined to just 3 cars every single, bought out instantly.
