Bugatti Veyron

The Bugatti Veyron EB 16.4 is a mid-engine sports car, designed and developed in Germany by the Volkswagen Group and Bugatti and manufactured in Molsheim, France, by French automobile manufacturer Bugatti. It was named after the racing driver Pierre Veyron.

The original version has a top speed of 407 km/h. It was named the 2000s Car of the Decade by the BBC television programme Top Gear. The standard Veyron also won Top Gear's Best Car Driven All Year award in 2005.

The Super Sport version of the Veyron is one of the fastest street-legal production cars in the world, with a top speed of 431.072 km/h. The Veyron Grand Sport Vitesse was the fastest roadster in the world, reaching an averaged top speed of 408.84 km/h in a test on 6 April 2013.

The Veyron's chief designer was Hartmut Warkuß, with the exterior being designed by Jozef Kabaň of Volkswagen. Much of the engineering work was conducted under the guidance of chief technical officer Wolfgang Schreiber. The Veyron includes a sound system designed and built by Burmester Audiosysteme.

Several special variants have been produced. In December 2010, Bugatti began offering prospective buyers the ability to customise exterior and interior colours by using the Veyron 16.4 Configurator application on the marque's official website. The Bugatti Veyron was discontinued in late 2014, but special edition models continued to be produced until 2015.

Origins
In May 1998, Volkswagen AG acquired the rights to use the Bugatti logo and the trade name Bugatti Automobiles S.A.S. To succeed the EB 110 model produced under the previous ownership, the automaker quickly released a series of concept cars whose technological advancements would culminate in the form of the Veyron 16.4.

Between October 1998 and September 1999, Bugatti introduced a series of Giugiaro-designed concept vehicles, each with permanent four-wheel drive and powered by the Volkswagen-designed W18 engine. The first car, the EB 118, was a 2-door luxury coupé presented at the 1998 Paris Motor Show. The next car, the EB 218, was a 4-door saloon presented at the 1999 Geneva Motor Show. The third and final car, the 18/3 Chiron, was a mid-engine sports car presented at the 1999 International Motor Show in Frankfurt.

In October 1999, Bugatti unveiled a fourth concept car at the Tokyo Motor Show. The EB 18/4 Veyron was a mid-engine sports car styled in-house under the direction of Hartmut Warkuß. In 2000, a modified version, the EB 16/4 Veyron, was displayed at motor shows in Detroit, Geneva, and Paris. Rather than the three-bank W18 engine of the four previous concept cars, the EB 16/4 featured the four-bank WR16 engine architecture installed in every production example of the Veyron. Warkuß also commissioned SEAT head of design, Walter de Silva, to submit a design proposal for the new Bugatti. The design was ultimately rejected in favour of Warkuß's own proposal.

The decision to start production of the car was made by the Volkswagen Group in 2001. The first roadworthy prototype was completed in August 2003. It is identical to the later series variant, except for a few details. In the transition from development to series production, considerable technical problems had to be addressed, repeatedly delaying production until September 2005. The Veyron EB 16.4 is named in honor of Pierre Veyron, a Bugatti development engineer, test driver and company race driver who, with co-driver Jean-Pierre Wimille, won the 1939 24 Hours of Le Mans while driving a Bugatti. The "EB" refers to Bugatti founder Ettore Bugatti and the "16.4" refers to the engine's 16 cylinders and quad-turbochargers.

Specifications and performance


The Veyron features an 8.0-litre, quad-turbocharged, W16 cylinder engine, equivalent to two narrow-angle V8 engines bolted together. Each cylinder has four valves for a total of 64, but the configuration of each bank allows two overhead camshafts to drive two banks of cylinders so only four camshafts are needed. The engine is fed by four turbochargers and displaces 7993 cc, with a square 86 by bore and stroke.

The transmission is a dual-clutch direct-shift computer-controlled automatic transmission having seven gear ratios, with magnesium paddles behind the steering wheel and a shift time of less than 150 milliseconds, built by Ricardo of England rather than Borg-Warner, who designed the six speed DSG used in the mainstream Volkswagen Group marques. The Veyron can be driven in either semi-automatic or fully-automatic mode. A replacement transmission for the Veyron costs just over US$120,000. It also has permanent all-wheel drive using the Haldex Traction system. It uses special Michelin PAX run-flat tyres, designed specifically to accommodate the Veyron's top speed, and cost US$25,000 per set. The tyres can be mounted on the wheels only in France, a service which costs US$70,000. Kerb weight is 1888 kg. This gives the car a power-to-weight ratio, according to Volkswagen Group's figures, of undefined PS  per ton. The car's wheelbase is 2710 mm. Overall length is 4462 mm which gives 1752.6 mm of overhang. The width is 1998 mm and height 1204 mm. The Bugatti Veyron has a total of ten radiators:
 * 3 heat exchangers for the air-to-liquid intercoolers.
 * 3 engine radiators.
 * 1 for the air conditioning system.
 * 1 transmission oil radiator.
 * 1 differential oil radiator.
 * 1 engine oil radiator

It has a (normal condition) and  (after lowering to the ground), and a frontal area of 2.07 m2. This gives it a drag area, the product of drag coefficient and frontal area, of.

Engine power output
According to Volkswagen Group and certified by TÜV Süddeutschland, the W16 engine utilised by the Veyron has a power output of 1001 PS, and generates 1250 Nm of torque.

Top speed
German inspection officials recorded an average top speed of the original version at 408.47 km/h during test sessions on Volkswagen Group's private Ehra-Lessien test track on 19 April 2005.

This top speed was almost matched by James May on Top Gear in November 2006, at the Ehra-Lessien test track, at 407.5 km/h. May noted that at top speed the engine consumes 45000 L of air per minute (as much as a human breathes in four days). Back in the Top Gear studio, co-presenter Jeremy Clarkson commented that most sports cars felt like they were shaking apart at their top speed, and asked May if that was the case with the Veyron at 407 km/h. May responded that the Veyron was very controlled, and only wobbled slightly when the air brake deployed.

The car's normal top speed is listed at 343 km/h. When the car reaches 220 km/h, hydraulics lower the car until it has a ground clearance of about 9 cm. At the same time, the wing and spoiler deploy. In this handling mode, the wing provides 3425 N of downforce, holding the car to the road.

Top speed mode must be entered while the vehicle is at rest. Its driver must toggle a special top speed key to the left of their seat, which triggers a checklist to establish whether the car and its driver are ready to attempt to reach 407 km/h. If so, the rear spoiler retracts, the front air diffusers shut, and normal 12.5 cm ground clearance drops to 6.5 cm.

Braking
The Veyron's brakes use cross drilled, radially vented carbon fibre reinforced silicon carbide (C/SiC) composite discs, manufactured by SGL Carbon, which have less brake fade and weigh less than standard cast iron discs. The lightweight aluminium alloy monobloc brake calipers are made by AP Racing; the front have eight titanium pistons and the rear calipers have six pistons. Bugatti claims maximum deceleration of 1.3 g on road tyres. As an added safety feature, in the event of brake failure, an anti-lock braking system (ABS) has also been installed on the handbrake.

Prototypes have been subjected to repeated 1.0 g braking from 312 km/h to 80 km/h without fade. With the car's acceleration from 80 km/h to 312 km/h, that test can be performed every 22 seconds. At speeds above 200 km/h, the rear wing also acts as an airbrake, snapping to a 55° angle in 0.4 seconds once brakes are applied, providing an additional 0.68 g (6.66 m/s2) of deceleration (equivalent to the stopping power of an ordinary hatchback). Bugatti claims the Veyron will brake from 400 km/h to a standstill in less than 10 seconds, though distance covered in this time will be half a kilometre (third of a mile).

Bugatti Veyron 16.4 Grand Sport (2009–2015)
The targa top version of the Bugatti Veyron EB 16.4, dubbed the Bugatti Veyron 16.4 Grand Sport, was unveiled at the 2008 Pebble Beach Concours d'Elegance. It has extensive reinforcements to compensate for the lack of a standard roof and small changes to the windshield and running lights. Two removable tops are included, the second a temporary arrangement fashioned after an umbrella. The top speed with the hardtop in place is the same as the standard coupé version, but with the roof removed is limited to 369 km/h—and to 130 km/h with the temporary soft roof. The Grand Sport edition was limited to 150 units, with the first 50 going exclusively to registered Bugatti customers. Production began in the second quarter of 2009.

Bugatti Veyron 16.4 Super Sport, World Record Edition (2010–2011)
The Bugatti Veyron 16.4 Super Sport is a faster, more powerful version of the Bugatti Veyron 16.4. Production was limited to 48 units. The Super Sport has increased engine power output of 882.3 kW at 6,400 rpm and a maximum torque of 1500 Nm at 3,000–5,000 rpm and a revised aerodynamic package. The Super Sport has been driven as fast as 431.072 km/h, making it the fastest production road car in the world at the time of its introduction although it is electronically limited to 415 km/h to protect the tyres from disintegrating.

The Bugatti Veyron 16.4 Super Sport World Record Edition is a version of the Bugatti Veyron 16.4 SuperSport. It is limited to five units. It has an orange body detailing, orange wheels, and a special black exposed carbon body. The electronic limiter is also removed with this version.

The model was unveiled in 2010 at The Quail, followed by the 2010 Monterey Historic Races at Laguna Seca, and the 2010 Pebble Beach Concours d'Elegance.

Top Speed World Record
On 4 July 2010, James May, a television presenter on BBC Two's television show Top Gear, drove the Veyron Super Sport on Volkswagen's Ehra-Lessien (near Wolfsburg, Germany) high-speed test track at 259.49 mph. Later that day, Bugatti's official test driver Pierre Henri Raphanel drove the Super Sport version of the Veyron at the same track to establish the car's top speed. With representatives of the Guinness Book of Records and German Technical Inspection Agency (TÜV) on hand, Raphanel made passes around the big oval in both directions achieving an average maximum speed of 431.072 km/h, thus taking back the title from the SSC Ultimate Aero TT as the fastest production vehicle of all time. The 431.072 km/h mark was reached by averaging the Super Sport's two test runs, the first reaching 427.933 km/h and the second 434.211 km/h.

When the record was certified it was already well known to the public that the customer car would be electronically limited to 415 km/h. Yet, after a query by the Sunday Times Guinness' PR director Jaime Strang was quoted on 5 April 2013: "As the car's speed limiter was deactivated, this modification was against the official guidelines. Consequently, the vehicle's record set at 431.072 km/h is no longer valid." On 10 April 2013, it was written on its website: "Guinness World Records would like to confirm that Bugatti's record has not been disqualified; the record category is currently under review."

On 15 April 2013, Bugatti's speed record was confirmed: "Following a thorough review conducted with a number of external experts, Guinness World Records is pleased to announce the confirmation of Bugatti's record of Fastest production car achieved by the Veyron 16.4 SuperSport. The focus of the review was with respect to what may constitute a modification to a car's standard specification. Having evaluated all the necessary information, Guinness World Records is now satisfied that a change to the speed limiter does not alter the fundamental design of the car or its engine."

Bugatti Veyron 16.4 Grand Sport Vitesse (2012–2015)


The Bugatti Veyron 16.4 Grand Sport Vitesse is a targa top version of the Veyron Super Sport. The engine in the Vitesse variant has a maximum power output of 1183.2 hp at 6,400 rpm and a maximum torque of 1500 Nm at 3,000–5,000 rpm. These figures allow the car to accelerate from a stand still to 100 km/h in 2.6 seconds. On normal roads, the Vitesse is electronically limited to 375 km/h.

The Vitesse was first unveiled at the 2012 Geneva Motor Show and later at the 2012 Beijing Auto Show and the 2012 São Paulo Motor Show.

Special editions
A number of special editions of the Vitesse were made:


 * The World Record Car (WRC) Edition was limited to 8 units, debuted in 2013, and went on sale for €1.99 million.

In 2013, Bugatti produced a series of Vitesse dedicated to racing legends, including Jean-Pierre Wimille, Jean Bugatti, Meo Costantini, and Ettore Bugatti. All six models in the Legend series are limited to three vehicles:

Records
A Bugatti Veyron 16.4 Grand Sport Vitesse driven by the Chinese racing driver Anthony Liu at Volkswagen Group's proving grounds in Ehra-Lessien became the fastest open-top production sports car, with a top speed of 408.84 km/h.

After the world record attempt, Dr. Wolfgang Schreiber, President of Bugatti Automobiles S.A.S, said "When we introduced the Vitesse, we established the top speed for open-top driving to be 375 km/h. Still, we could not let go of the idea of reaching the 400 km/h mark with this car as well. The fact that we have succeeded in reaching 408.84 km/h is a thrill for me, and it reaffirms once again that Bugatti is the leader when it comes to technology in the international automotive industry." The driver, Anthony Liu, claimed "Even at such high speeds it remained incredibly comfortable and stable. With an open-top, you can really experience the sound of the engine and yet even at higher speeds I did not get compromised by the wind at all."

Bugatti Veyron Linea Vincero
The Bugatti Veyron Linea Vincero is a Veyron 16.4 modified by the German car modification firm Mansory.

The Linea Vincero has new wheel rims and new exterior lower bodywork. It extensively uses carbon fibre in the interior and exterior as well.

This car, with its interior and exterior customisations, is worth US$1 million more than a standard Veyron 16.4.

Bugatti Veyron Linea D'oro
The Bugatti Veyron Linea D'oro is a car made on the basis of the Veyron Grand Sport and the 16.4 by the German car modification firm Mansory.

The D'oro's exterior design is identical to its predecessor's but it has a few differences such as the gold paint on the badge, rims and other features. The iconic V-shaped badge is also present on this car's front grille.

Bugatti Veyron Linea Viviere
The Bugatti Veyron Linea Viviere (commonly known as the Mansory Viviere) is a car made on the basis of the Bugatti Veyron Super Sport by the German car modification firm Mansory.

This car's exterior design features the iconic V-shaped front grille and an additional exhaust system below its rear lights. The interior has been handcrafted and carbon fibre has been extensively used.

This car has a second generation known as the Viviere Diamond Edition which has been made on the same basis. This car is the final Veyron Edition tuned by Mansory and has a marble coloured exterior paintwork.

The Bugatti Veyron Linea Viviere costs US$2.3 million, making it one of the most expensive Veyrons ever produced.

Production
, 405 cars had been produced and delivered to customers worldwide, with orders that have already been placed for another 30. Bugatti was reported to produce 300 coupés and 150 roadsters up to the end of 2015. Production amounted to 450 units in a span of over 10 years. The final production vehicle, a Grand Sport Vitesse titled "La Finale" (The Last One), was displayed at the Geneva Motor Show from 5–15 March 2015.

Future development
In 2008, Bugatti then-CEO Dr Franz-Josef Paefgen confirmed that the Veyron would be replaced by another high-end model by 2012. In 2011, the new CEO Wolfgang Dürheimer revealed that the company was planning to produce two models in the future — one a sports car-successor to the Veyron, the other a limousine known as the Bugatti 16C Galibier, which was later cancelled since Bugatti was later then working on a successor to the Veyron, which became the Bugatti Chiron.

The successor to the Veyron was unveiled in concept form as the Bugatti Vision Gran Turismo at the September 2015 Frankfurt Motor Show.

A toned-down version of the radically styled Vision Gran Turismo concept car, now called the Chiron, debuted at the March 2016 Geneva Motor Show. Production started in 2017 and will be limited to 500 units.

Top Gear
All three former presenters of the popular BBC motoring show Top Gear have given the Veyron considerable praise. While initially skeptical that the Veyron would ever be produced, Jeremy Clarkson later declared the Veyron "the greatest car ever made and the greatest car we will ever see in our lifetime", comparing it to Concorde and S.S. Great Britain. He noted that the production cost of a Veyron was GB£5 million, but was sold to customers for just GB£1 million. Volkswagen designed the car merely as a technical exercise. James May described the Veyron as "our Concorde moment". Clarkson test drove the Veyron from Alba in northern Italy to London in a race against May and Richard Hammond who made the journey in a Cessna 182 aeroplane.

A few episodes later, May drove the Veyron at the VW test track and took it to its top speed of 407.16 km/h. In series 10, Hammond raced the Veyron against the Eurofighter Typhoon and lost. He also raced the car in Series 13 against a McLaren F1 driven by The Stig in a one-mile (1.6 km) drag race in Abu Dhabi. The commentary focused on Bugatti's "amazing technical achievement" versus the "non-gizmo" racing purity of the F1. While the F1 was quicker off the line and remained ahead until both cars were travelling at approximately 200 km/h, the Bugatti overtook its competitor from 200 to 300 km/h and emerged the victor. Hammond has stated that he did not use the Veyron's launch control in order to make the race more interesting.

The Veyron also won the award for "Car of the Decade" in Top Gear end of 2010 award show. Clarkson commented, "It was a car that just rewrote the rule book really, an amazing piece of engineering, a genuine Concorde moment". When the standard version was tested in 2008, it did not reach the top of the lap time leader board, with a time of 1:18.3, which was speculated as being due to the car's considerable weight disadvantage against the other cars towards the top. In 2010 the SuperSport version achieved the fastest ever time of 1:16.8 (dethroned the Gumpert Apollo S, replaced by the Ariel Atom V8 in 2011), as well as being taken to a verified average top speed of 431 km/h by Raphanel on the programme, thenceforth retaking its position as the fastest production car in the world.

Martin Roach
In 2011, Martin Roach's book Bugatti Veyron: A Quest for Perfection – The Story of the Greatest Car in the World took the stance that the car had now become so famous that it is effectively a bona fide celebrity. The book follows its author as he attempts to track down and drive the car, along the way interviewing chief designers, test drivers, and the president of Bugatti.

Gordon Murray
During its development period McLaren F1 designer Gordon Murray said in UK auto magazine Evo: "The most pointless exercise on the planet has got to be this four-wheel-drive, thousand-horsepower Bugatti." But after driving it he called it "a huge achievement".

Murray was impressed with the Veyron's engine and transmission after he test drove one for Road & Track magazine. He also praised its styling: "The styling is a wonderful mélange of classic curves and mechanical edges and elements — this should ensure that the car will still look good years from now, and therefore have a chance of becoming a future classic."
