The Bugatti Veyron EB 16.4 is a mid-engined sports car, designed and developed in Germany by the Volkswagen Group and manufactured in Molsheim, France, by Bugatti Automobiles S.A.S.
The original version had a top speed of 407 km/h (253 mph).[4] It was named Car of the Decade and best car award (2000–2009) by the BBC television programme Top Gear. The standard Bugatti Veyron also won Top Gear's Best Car Driven All Year award in 2005.
The current Super Sport version of the Veyron is recognised by Guinness World Records as the fastest street-legal production car in the world, with a top speed of 430.9 km/h (267.7 mph),[5] and the roadster Veyron Grand Sport Vitesse version is the fastest roadster in the world, reaching an averaged top speed of 408.84 km/h (254.04 mph) in a test on 6 April 2013.[6][7]
The Veyron's chief designer was Hartmut Warkuss, and the exterior was designed by Jozef Kabaň of Volkswagen, with much of the engineering work being conducted under the guidance of engineering chief Wolfgang Schreiber.
Several special variants have been produced. In December 2010, Bugatti began offering prospective buyers the ability to customise exterior and interiors colours by using the Veyron 16.4 Configurator application on the marque's official website. The Bugatti Veyron was discontinued in late 2014.[8][9]

Origins
In 1998, the Volkswagen Group purchased the trademark rights on the former car manufacturer Bugatti in order to revive the brand.[10] Starting with the Bugatti EB118, they presented at various international auto shows a total of four 18-cylinder concept cars. At the 1999 Tokyo Motor Show, the first study of the Veyron was presented.[11] At the time, the name of the concept car was "Bugatti Veyron EB 18.4," and it was equipped with a 3-bank W18 engine instead of the 2-bank W16 engine of the production version. While the three previous prototypes had been styled by Giugiaro, the Veyron was designed by the Volkswagen stylists.The decision to start production of the car was taken 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.[12]
The Veyron EB 16.4 is named in honour 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.[13] The "EB" refers to Bugatti founder Ettore Bugatti and the "16.4" refers to the engine's 16 cylinders and 4 turbochargers.[14]
World record controversy
A controversy developed in 2013 over the Veyron Super Sport's status as the world’s fastest production car, ultimately resolved in the Veyron's favor.In early April 2013, driving.co.uk (also known as Sunday Times Driving) began an investigation following claims from US car maker Hennessey that its 928 kW (1,244 bhp) Hennessey Venom GT was entitled to the Guinness World Record. With a recorded speed of 427.6 km/h (265.7 mph) the Hennessey was 3.4 km/h (2.1 mph) slower than the Veyron but Hennessey dismissed Bugatti’s official record saying that the Veyron Super Sport was restricted to 415 km/h (258 mph) in production form and that for it to achieve its record top speed of 431.0 km/h (267.8 mph), the car used was in a state of tune not available to customers. Hennessey said its Venom GT was road-ready and unmodified and was therefore a production car in the strict sense of the term.[15]
Driving.co.uk requested clarification from Guinness World Records, which investigated this claim and found that the modification was against the official guidelines of the record. Upon finding this, Guinness World Records voided the Super Sport's record and announced it was "reviewing this category with expert external consultants to ensure our records fairly reflect achievements in this field."
After further review, Shelby SuperCars, the producers of the Ultimate Aero TT, said that they had reclaimed the record,[17] however Guinness reinstated the Super Sport's record after coming to the conclusion that "a change to the speed limiter does not alter the fundamental design of the car or its engine."
Bugatti Veyron (2005–2011)
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 VR8 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 7,993 cubic centimetres (487.8 cu in), with a square 86 by 86 mm (3.39 by 3.39 in) bore and stroke.
The transmission is a dual-clutch direct-shift gearbox computer-controlled automatic with 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.[19] The tyres can be mounted on the rims only in France, a service which costs US$70,000. Kerb weight is 1,888 kilograms (4,162 lb).[20] This gives the car a power-to-weight ratio, according to Volkswagen Group's figures, of 530 PS (390 kW; 523 bhp) per ton.
The car's wheelbase is 2,710 mm (106.7 in). Overall length is 4,462 mm (175.7 in) which gives 1,752.6 mm (69.0 in) of overhang. The width is 1,998 mm (78.7 in) and height 1,204 mm (47.4 in). 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
Engine output
According to Volkswagen Group and certified by TÜV Süddeutschland, the final production Veyron engine produces 1,001 metric horsepower (736 kW; 987 bhp) of motive power, and generates 1,250 newton metres (922 lbf·ft) of torque.[2][24] The nominal figure has been stated by Bugatti officials to be conservative, with the real total being 1,020 metric horsepower (750 kW; 1,006 bhp) at 6,000 rpm.Top speed
German inspection officials recorded an average top speed of the original version of 408.47 km/h (253.81 mph during test sessions on Volkswagen Group's private Ehra-Lessien test track on 19 April 2005.This top speed was equalled by James May on Top Gear in November 2006, at the Ehra-Lessien test track. May noted that at top speed the engine consumes 45,000 litres (9,900 imp gal) 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 supercars 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 (253 mph). May responded that the Veyron was very controlled, and only wobbled slightly when the air brake deployed.
The car's everyday top speed is listed at 343 km/h (213 mph). When the car reaches 220 km/h (140 mph), hydraulics lower the car until it has a ground clearance of about 9 cm (3.5 in). At the same time, the wing and spoiler deploy. In this handling mode, the wing provides 3,425 newtons (770 lbf) 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 (253 mph). If so, the rear spoiler retracts, the front air diffusers shut, and normal 12.5 cm (4.9 in) ground clearance drops to 6.5 cm (2.6 in).
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 a much greater resistance to brake fade when compared with conventional cast iron discs.[citation needed] The lightweight aluminium alloy monobloc brake calipers are made by AP Racing; the fronts have eight[21] 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 (194 mph) to 80 km/h (50 mph) without fade. With the car's acceleration from 80 km/h (50 mph) to 312 km/h (194 mph), that test can be performed every 22 seconds. At speeds above 200 km/h (120 mph), 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 (250 mph) 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 Bugatti Veyron 16.4 Grand Sport version of the Bugatti Veyron EB 16.4 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 down is limited to 369 km/h (229 mph)—and to 130 km/h (81 mph) with the temporary soft roof. The Gran 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, with the car priced at €1.4 million (excluding taxes and delivery).A version was introduced at the Qatar Motor Show 2012 with a horizontal colour split with a bright yellow body framed in visible black carbon (including black-tinted wheels), seats in yellow-coloured leather upholstery with black stitching, middle console in black carbon, dashboard, steering wheel and gearshift made of black leather with yellow stitching. It was priced at €1.58 million.

Special versions
Sang Noir (2011)
The Sang Noir was introduced as a show car at the 2011 Geneva Motor Show for customers who did not like the look of the ‘World Record Edition’. It is finished entirely in black, except for the interior, which is bright tangerine orange. The car costs a very high US$3.4 million, US$1 million more than a standard Super Sport.Motorsports
On 4 July 2010 James May, a television presenter on BBC Two's television show Top Gear, drove the Veyron Super Sport at 417.61 km/h (259.49 mph). Later that day, Bugatti's official test driver Pierre Henri Raphanel drove the Super Sport version of the Veyron on Volkswagen's Ehra-Lessien (near Wolfsburg, Germany) high-speed test 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 (267.856 mph), 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 427.93 km/h (265.90 mph) and the second 434.20 km/h (269.80 mph).On 9 April 2013 the Title of "Fastest Production Car in the World" was revoked due to the deactivation of the electronic speed limiter which makes the car non stock, going against the rules of the title. Later, Bugatti’s speed record has been restored. "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 Super Sport. 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."
Grand Sport Vitesse (2011-2015)
Bugatti Veyron 16.4 Grand Sport Vitesse is a version of the Grand Sport with a Super Sport engine. It produces a maximum output of 1,200 PS (880 kW; 1,200 bhp) @ 6,400 rpm and a maximum torque of 1,500 N·m (1,100 lb·ft) @ 3,000-5,000 rpm. These figures allow the car to reach 100 km/h (62 mph) from standing in 2.6 seconds. On normal roads, the Vitesse is electronically limited to 375 km/h (233 mph).
The vehicle was unveiled at the 2012 Geneva Motor Show and later appeared at the 2012 Beijing Auto Show and the São Paulo Motor Show 2012.
Base price of the Vitesse costs €1.69 million (without tax and transportation), with the 2012 Geneva Motor Show car costs €1.79 million, São Paulo Motor Show 2012 car costs €1.9 million.
Special editions
A number of special editions of the Vitesse were made. The Vitesse SE, inspired by Bugatti Type 37A, was unveiled in 2012 and sold for €1.74 million (US$2.2 million). 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 Vitesses dedicated to racing legends, including Jean-Pierre Wimille Jean Bugatti,and Meo Costantini. and Ettore Bugatti.
Motorsports
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 speed of 408.84 km/h (254.04 mph). The vehicle was unveiled in Shanghai Motor Show 2013.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.”
Production
As of 6 August 2014, 405 Veyrons have been produced and delivered to customers worldwide, with orders have already been placed for another 30. Bugatti was reported to produce 300 coupes and 150 roadsters up to the end of 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.See related: Bugatti 16C Galibier
