A Super Sports Cars Roadster Made by Bugatti

The idea was to create a car that would redefine the boundaries of technology in automotive construction while appealing to the aesthetically inclined and connoisseurs of exceptional automobiles.

To design a roadster that would join the boundless creativity of its designers and the superior skill of its engineers – without compromise on either side.  A car that would unite the pinnacle of luxury and unparalleled driving performance to a harmonious whole.

The idea was to provide maximum enjoyment without losing sight of safety and comfort. The idea was to build the world’s fastest convertible car. Bugatti turned this idea into reality: the super sports car Bugatti Veyron 16.4 Grand Sport.

The Grand Sport defies conventional categories. The superior harmony of its design transcends the ordinary, lending the Bugatti Veyron 16.4 Grand Sport its unique character. The open-topped super sports car displays its power, performance, and self-assertion as a matter of course. Simultaneously, it exudes charisma, perfection, and elegance.

In other words: it is a Bugatti that follows the technological and aesthetic examples of Ettore Bugatti’s Grand Sport models of the late 1920s – a true Bugatti.

Exclusive Class, Precise Workmanship and a Passion for Detail

Ageless, elegant design, the finest high-quality materials, and exceptional crafting: these are the qualities that define the Bugatti Veyron 16.4 Grand Sport’s interior.

The maxim was to concentrate on the essentials – nothing in excess, nothing lacking. Each detail was designed with passion and precision and crafted meticulously and lovingly by hand.

Only soft, supple, full-grain napa leather of the highest quality was used for the Grand Sport. The careful treatment of this superb material maintains its natural breathability. The stitching of the seat covers represents an acceleration curve and was executed following the historical quilting method in a modern reinterpretation for automobile interiors.

The moisture-repellent leather is yet another feature with which the Grand Sport meets the highest standards for an open-top sports car. The result is minimal aesthetics at its most elegant, a harmonious balance of form and function. The interior brings this concept to life, allowing it to be experienced with all senses.

The New Dimension of Roadster Feeling

The transparent roof is one of the Bugatti Veyron 16.4 Grand Sport’s masterstrokes.

It boasts a maximum area of tinted glass that lets in the sunlight without unwanted heat. To underscore the Grand Sport’s feeling of perfect harmony, the roof’s inside frame features full leather lining in the same colour as the car’s interior. The perfectly aligned roof is easily removed and stored on a special interior fixture.

Driven with an open roof, the Grand Sport offers an unequalled experience and intensely immediate impressions of the surrounding landscape – right up to a recommended top speed of 360 km/h. An elegantly swept-back windscreen and a rear window with corresponding shape and size guarantee ideal visibility as well as turbulence-free airflow and characterize the Grand Sport’s roadster design.

The patented textile canopy, comparable in its functionality to an umbrella, is as ingenious and unique as it is innovative. Colour-coordinated with the car’s exterior, it enhances the Grand Sport’s elegant contours. This water-repellent accessory can be easily stored in the trunk. Light and convenient, it is quickly and single-handedly fixed into position, where it remains firmly and securely in place up to speeds of 130 km/h. An alarm announces possible turbulence problems if this speed is exceeded.

A Roadster That Unites State-of-the-art Sports Car Features

The challenge: to develop a roadster that would unite previously unattained features in one exceptional vehicle. A challenge Bugatti decided to take on.

The Bugatti Veyron 16.4 Grand Sport combines state-of-the-art technology and the beauty of a convertible.

Extreme precision and meticulous care for detail – those were the governing principles followed by the designers and engineers as they created the Grand Sport.

This maxim of perfection found its expression in the car’s technology: the Grand Sport’s engine, drive, and brakes all deliver superlatives in performance, acceleration, and deceleration. The choice of materials is another indicator of Bugatti’s discerning standards: titanium, carbon fibre, magnesium, aluminium – each component is made of the material with the lowest weight and the highest level of functionality.

This is also true for the chassis safety features. The Grand Sport’s body consists of a carbon fibre monocoque suspended from an aluminium frame in the front and a carbon fibre/stainless steel frame in the rear. In assembly, too, perfection is the guiding principle: the Grand Sport is manufactured lovingly and meticulously by hand. This guarantees that precise care is given even to the tiniest details.

A Roadster with Top Performance

The Bugatti Veyron 16.4 Grand Sport’s seven-gear, twin-clutch gearbox is the first to master comparably high torque values.

The Bugatti Veyron 16.4 Grand Sport combines state-of-the-art technology and the beauty of a convertible.

Extreme precision and meticulous care for detail – those were the governing principles followed by the designers and engineers as they created the Grand Sport.

It combines the advantages of a manual transmission and the convenience of an automatic to deliver smart performance: the next gear is pre-engaged, ready to take over propulsion seamlessly and without a moment of deceleration.

This technological masterstroke allows for calm, smooth and even acceleration with minimal shift times – less than 150 milliseconds. With 16 cylinders, a combined capacity of 8 litres, 4 valves per cylinder and four turbo chargers, the Grand Sport’s engine is the most powerful ever to be built into a production vehicle. The perfect combination of a 1,001 horsepower high-performance power unit and 1,250 Newton meter torque results in an unparalleled forward thrust. The Launch Control provides additional support for a quick start, and the Cruise Control makes for constant driving even at high velocity.

A glance at the horsepower control in the Grand Sport’s dashboards reveals this unique car’s full potential: constant 250 km/h require merely 270-280 of the Grand Sport’s horsepower capacity. More than 700 HP are continuously “on standby” for quick and fast interludes. In other words: at 1,000 r.p.m., only slightly above idling, the Veyron has 730 Newton meter torque available. Between 2,200 and 5,500 r.p.m., 1,250 Newton meter torque are permanently accessible.

Faster to a Full Stop

0 to 100 km/h in 2.3 seconds and less than 10 seconds from 407 to a full standstill – if there is one area in which the Bugatti Veyron 16.4 Grand Sport excels even more than in acceleration, it is the exact opposite: braking.

Intelligent carbon-ceramic brake discs with interior ventilation, eight-piston monoblock caliper units in the front, and six-piston caliper units in the rear provide a maximum of braking power and optimum cooling. At velocities exceeding 200 km/h, the rear spoiler serves as additional air brake. Activated by the brake pedal, the spoiler shoots up and is deployed at a 55-degree angle in less than 0.4 seconds. This allows the car to come to a full stop from 100 km/h in just 32 metres

Top Speeds With Open Top

0 to 100 km/h in 2.5 seconds – the Bugatti Veyron 16.4 Grand sport is on a par with modern Formula 1 racecars. 200 km/h in 7.3 seconds, 9.8 seconds for the traditional quarter mile, 407 km/h top velocity. No other convertible ever reached such performance values. Once again, Bugatti is writing automotive history.

The extraordinary velocity of the Bugatti Veyron 16.4 calls for equally extraordinary aerodynamics. To this end the Grand Sport uses three configuration modes that optimally exploit the force impact to provide a maximum of stability.

The standard mode is used for speeds up to 220 km/h. At higher velocities, the handling mode is engaged, pulling the vehicle closer to the road surface and deploying the rear spoiler at 15 degrees. Driven with an open roof, the super sports car automatically adjusts this angle to 20 degrees in order to maintain the downforce while preserving the aerodynamic balance.

The top speed mode is activated by the driver, who uses his special key to unlock this mode before starting the engine. The top speed mode lowers the position of rear wing and spoiler to 2 degrees and minimizes the chassis clearance, thus enabling the Grand Sport to reach its top velocity – more than 400 kilometres per hour. An enjoyment that the driver needs to be prepared for before he starts, for velocities like these can only be reached with a closed top.

Top Priority: Maximum Safety

The Bugatti Veyron 16.4 Grand Sport provides a maximum of safety both during acceleration and at high speeds.

This superior security is made possible by the precise aerodynamic balance of lift and downforce. Ground clearance and the position of the rear spoiler are adjusted automatically to suit the driving situation, keeping the super sports car securely on the road. The four-point electronic stability programme additionally enhances driving safety at high speed. At the heart of the system is the four-wheel drive: the Haldex clutch distributes the torque to the front and rear axles, while the rear differential lock ensures the dynamics of the rear wheels for smooth negotiation of fast curves.

The perfectly designed suspension and precise steering give the car excellent stability even at top speeds. The electronic stability programme (ESP) acts on each individual wheel, resulting in previously unmatched reaction times. The ESP also provides intelligent motor management control. At the centre of this highly sophisticated technology is the telemetric computer, which controls all vehicle data. This information can be accessed at all times via the Grand Sport’s PDA, integrated in the dashboard.

The consistent use of carbon fibre in the car’s body ensures enhanced rigidity despite the open form of the Grand Sport. This lightweight, yet ultra-strong material is also used to reinforce the doors, resulting in the lowest torsion to be found in a convertible. Indispensable but commonly unsightly, the roll hoops in the Grand Sport are smartly integrated in the air sockets. Thus, they provide constant rollover protection while remaining completely invisible.

Superb Sound and Maximum Comfort Beneath the Sky

The technical equipment of the Bugatti Veyron 16.4 Grand Sport is in a class of its own, delivering unforgettable sound and comfort at any speed, even with the top open.

Those passionate about unusual, ingenious solutions will love the 2.7-inch monitor integrated in the rear-view mirror. Once the reverse gear is engaged, the camera built in just above the license plate offers the driver an unobstructed view of the area behind the vehicle. Park Distance Control provides additional assistance.

The audio system “Puccini”, designed especially for a convertible car, features a digital signal processor as well as a series of interfaces for numerous external devices, including the iPod. The Grand Sport’s integrated PDA includes a GPS route guidance system that assists drivers in securely finding their destination. If the PDA is stashed safely in the glove compartment, the directions are displayed unobtrusively on the rear-view mirror.

The Bugatti Veyron 16.4 Grand Sport’s climate control system is able to identify whether the roof is open or closed. It automatically readjusts the temperature to the previous setting for the respective situation.

Grand Sport drivers can leave the roof of their vehicle open when they park it – the glove compartment, the console compartment between the seats, the fuel tank cap, and the oil-filler neck can all be locked remotely.

The aerials for the Bugatti Veyron 16.4 Grand Sport’s audio, telephone, and telemetry systems are “invisible”, integrated in the dashboard and the air-scoop.

Assembled by hand at the company’s headquarters in Molsheim, Alsace, the Grand Sport will be delivered from July 2009 onwards at a price of 1.4 million euros (excluding taxes and transportation). Just 150 units will be made, with the first 50 of these going exclusively to registered Bugatti customers.
