The Bugatti Veyron EB 16.4 is a mid-engined grand touring car. The Super Sport version is the fastest production car in the world, with a top speed of 431.072 kilometres per hour (267.856 mph).The original version has a top speed of 408.47 km/h (253.81 mph).

Designed and developed by the German Volkswagen Group and produced by Bugatti Automobiles SAS at their headquarters in Château St. Jean in Molsheim (Alsace, France), 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 a former VW engineer and now Bugatti Engineering chief Wolfgang Schreiber.

The car is named after French racing driver Pierre Veyron, who won the 24 hours of Le Mans in 1939 while racing for the original Bugatti company. It was named Car of the Decade (2000–2009) by the BBC television programme Top Gear.

A number of special variants have been produced, including two targa tops.

Specifications and performance

The Veyron features an 8.0 litre W16 engine with sixteen cylinders in four banks of four, equivalent to two narrow-angle V8 engines mated in a W configuration. Each cylinder has four valves for a total of sixty four, but the narrow staggered eight configuration 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 (3.4 by 3.4 in) bore and stroke. The official test driver Pierre Henri Raphanel drove the Super Sport version of the Veyron on Volkswagen's Ehra-Lessien high-speed oval to establish the cars 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 speed of 431.072 km/h (267.856 mph).

The Super Sport features an engine power increase from the standard 1,001 metric horsepower (736 kW; 987 hp) to 1,200 metric horsepower (883 kW; 1,184 hp) and torque of 1,500 N⋅m (1,100 lbf⋅ft) and a revised aerodynamic package.

The first five production Super Sports will sport the same black and orange finish as the record car and all production models will be electronically limited to 415 km/h (258 mph) to protect the tyres. The Veyron Super Sport was shown publicly for the first time at the Pebble Beach Concours d'Elegance in August 2010.

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, 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- or fully-automatic mode. A replacement transmission for the Veyron costs just over $120,000. It also has permanent four wheel drive using the Haldex Traction system. It uses special Michelin PAX run flat tyres, designed specifically to accommodate the Veyron's top speed, which reportedly cost $25,000 US per set. The tyres can only be removed from the rims in France, a service which reportedly costs $70,000. Kerb weight is 2,034.8 kilograms (4,486 lb). This gives the car a power to weight ratio, according to Volkswagen Group's 1,001 brake horsepower (746 kW; 1,015 PS) figures, of 446.3 bhp per ton.

The car's wheelbase is 2,710 mm (106.7 in). Overall length is 4,462 mm (175.7 in), width 1,998 mm (78.7 in) and height 1,204 mm (47.4 in).

The Bugatti Veyron has a total of ten radiators.

• 4 radiators for the engine cooling system.
• 1 heat exchanger for the air-to-liquid intercoolers.
• 2 for the air conditioning system.
• 1 transmission oil radiator.
• 1 differential oil radiator.
• 1 engine oil radiator.

It has a drag coefficient of 0.41 (normal condition) and 0.36 (after lowering to the ground), and a frontal area of 2.07 square metres (22.3 sq ft). This gives it a C_dA value of 8.0 sq ft (0.74 m).

Engine output

According to Volkswagen Group and certified by TÜV Süddeutschland, the final production Veyron engine produces 1,001 brake horsepower (746 kW; 1,015 PS) of motive power, and generates 1,250 newton-metres (922 lbf⋅ft) of torque. The nominal figure has been stated by Bugatti officials to be conservative, with the real total being 1020 bhp or more.

Top speed

The top speed of the original version was verified by James May on Top Gear in November 2006, again at Volkswagen Group's private Ehra-Lessien test track. Jeremy Clarkson, driving a Veyron from Italy to London, noted that at top speed the engine consumes 10,000 imperial gallons (45,000 L) of air per minute (as much as a human breathes in four days). With a 0–60 mph time of 2.4 seconds, the Veyron has the fastest top speed of any street legal car. Once back in the Top Gear studio, James was asked by co-presenter Jeremy Clarkson what the Veyron felt like to drive at 407 km/h (253 mph), May replied that it was "totally undramatic", and very stable at speed.

German inspection officials recorded an average top speed of 408.47 km/h (253.81 mph) during test sessions on the Ehra-Lessien test track on 19 April 2005. On 4 July 2010, Bugatti's official test driver Pierre Henri Raphanel piloted the Super Sport edition and was clocked at an average of 431.072 km/h (267.856 mph) on the same track, taking back the title of the fastest production vehicle of all time from the SSC Ultimate Aero TT. The 431.072 km/h mark was reached by averaging the Super Sport's two test runs, the first topping out at 265.96 mph (427.93 km/h) and the second at 269.86 mph (434.20 km/h). The record run was certified by the German government and the Guinness Book of World Records.

The car's everyday top speed is listed at 350 km/h (220 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. This is the handling mode, in which the wing helps provide 3,425 newtons (770 lbf) of downforce, holding the car to the road. The driver must, using a special key (the top speed key), toggle the lock to the left of his seat in order to attain the maximum (average) speed of 407 km/h (253 mph). The key functions only when the vehicle is at a stop, when a checklist then establishes whether the car and its driver are ready to enable top speed mode. If all systems are go, the rear spoiler retracts, the front air diffusers shut and the ground clearance, normally 12.5 cm (4.9 in), 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. The lightweight aluminium alloy monobloc brake calipers are made by AP Racing; the fronts 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 (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/s) 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 a third of a mile.

Bleu Centenaire

A celebratory model unveiled at the 2009 Geneva Motor Show. for the 100th anniversary of the Bugatti brand. The entire body is painted in a combination of matte and gloss "Bugatti Blue", the mid-section between the two wings on the hood is expanded, and a chrome strip up the middle added.

Grand Sport

A targa top version unveiled at Pebble Beach Concours d'Elegance on 15 August 2008, with production beginning in spring 2009. The model has extensive reinforcements to compensate for the lack of standard roof, and small changes to the windshield and running lights. There are two removable tops, the second a temporary roof 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 first (chassis 001) was sold at auction, raising approximately $900,000 for charity.

Super Sport

Improved aerodynamics kit, 1,200 PS (883 kW) 1,500 newton-metres (1,100 lbf⋅ft) torque engine upgrade. It has a 431.072 km/h (267.856 mph) top speed, making it the fastest road car in production, although it is electronically limited to 257.91 mph (415.07 km/h) to protect the tyres from disintegrating. The first five of an unannounced production run made its debut in a matte black and orange color combination, all of which have been spoken for. The public debut was at the Pebble Beach Concours d'Elegance in August 2010.

The Super Sport was featured on Series 15, Episode 5 of Top Gear, where presenter, James May attempted to set the speed record. It managed 259.11 mph (417.00 km/h), briefly setting a new production car speed record. Later in the day though, one of Bugatti's test drivers (Pierre Henri Raphanel) broke May's previous record, claiming it through runs in both directions (May only did one run in one direction) and registering an average top speed of 431.072 km/h (267.856 mph). The car then went round the Top Gear Test Track and topped the lap leader board with a 1:16.8 time, beating the 1:17.1 record set previously by the Gumpert Apollo Sport.

Criticisms and comments

Reviews

Gordon Murray, designer of the McLaren F1 (which for many years was the fastest production car ever built) said the following about the Bugatti Veyron in UK auto magazine evo during its development period:

The most pointless exercise on the planet has got to be this four-wheel-drive thousand-horsepower Bugatti. I think it's incredibly childish this thing people have about just one element—top speed or standing kilometre or 0–60. It's about as narrow minded as you can get as a car designer to pick on one element. It's like saying we're going to beat the original Mini because we're going to make a car 10mph faster on its top speed—but it's two foot longer and 200 kilos heavier. That's not car designing—that just reeks of a company who are paranoid...

Murray later brought up and criticized Volkswagen for "scamming" car buyers in the 90s for buying the cheapest parts possible for the production of Jettas and Golfs, allowing Volkswagen to make a larger profit off their car sales, funding the construction of the Bugatti Veyron. However, Murray was impressed with the Veyron's engine and transmission after he test drove one for Road and Track magazine.

Top Gear

On Top Gear the car has received considerable praise from all three presenters. Jeremy Clarkson declared the Veyron "the greatest piece of engineering ever. No, I'm sorry, this is the greatest car ever made and the greatest car we will ever see in our lifetime." James May proclaimed that the Veyron is "our Concorde moment". To review the car, Clarkson drove from Alba, northern Italy to London whilst racing James May and Richard Hammond who were travelling in a Cessna 182 aeroplane.

A few episodes later, James May drove the Veyron at the VW test track and took it to its top speed of 253 mph (407.16 km/h). During the second episode of the 13th season, Richard Hammond raced the Veyron against the McLaren F1 driven by The Stig in a one mile drag race in Abu Dhabi, commenting 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's end of 2009 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, it did not reach the top of the lap time leader board, which was speculated as being due to the car's considerable weight disadvantage against the other cars towards the top. The SuperSport version, however, achieved the fastest ever time of 1.16.8, as well as being taken to a (verified) average top speed of 431.072 km/h (267.856 mph) by a Bugatti test driver on the programme, henceforth retaking its position as the fastest production car in the world.
