History
Development of this vehicle began with the 1999 EB 18.4 "Veyron" concept car. Introduced at the Tokyo Motor Show, it was similar in design and appearance to the final Veyron production car. One major difference was the EB 18.4's use of a W18 engine with three banks of six cylinders. The Veyron's head designer was Hartmut Warkuss with exterior designed by Jozef Kabaň of Volkswagen rather than Giorgetto Giugiaro of ItalDesign who had handled the three prior Bugatti concepts too.
VW chairman Ferdinand Piëch announced the production Veyron at the 2000 Geneva Motor Show. It was promised to be the fastest, most powerful, and most expensive car in history. Instead of the W18, the production model would use a VR6/WR8-style W16 engine. First seen in the 1999 Bentley Hunaudieres concept car, the W16 would get four turbochargers, producing a quoted 1001 horsepower (see engine section for details on the power output). Top speed was promised at 407 km/h (253 mph), and pricing was announced at €1 million (US$1.3 million at the time).
Development continued throughout 2001 and the EB 16/4 Veyron was promoted to "advanced concept" status. In late 2001, Bugatti announced that the car, officially called the Bugatti Veyron 16.4, would go into production in 2003. However, the car experienced significant problems during development. Achieving the required high-speed stability was difficult - one prototype was destroyed in a crash and another spun out during a public demonstration at the Monterey Historics event in Mazda Raceway at Laguna Seca. Production of the Veyron was delayed pending resolution of these and other issues.
Piëch retired that year as chairman of the Volkswagen Group and was replaced by Bernd Pischetsrieder. The new chairman promptly sent the Veyron back to the drawing board for major revisions. Neumann was replaced as Bugatti president by Thomas Bscher in December 2003, and substantial modifications were made to the Veyron under the guidance of former VW engineer, Bugatti Engineering head Wolfgang Schreiber.
Each Veyron is being sold for over £800,000, or 1.2 million American dollars, (net pay, without taxes), prices vary by exchange rates and local taxes (like value added taxes). As Bugatti, and therefore Volkswagen, are making such a loss, it has been likened by automotive journalist Jeremy Clarkson and his Top Gear programme team in their story on it to the Concorde, in that both were huge achievements, but the car will probably, like the plane before it, be discontinued after proving to be an economic failure.
In the case of the Veyron, it will be several years before Volkswagen will be able to see if their investment in developing ground-breaking technology has paid off. One key measure is how much (if any) of the technology developed for the Veyron finds use in mass-produced cars.
[edit] Official unveiling
The production Veyron was shown for the first time on October 19, 2005 at the Tokyo Motor Show.
The official United States launch for the production version occurred at the 2006 Los Angeles International Auto Show in January.
Visual differences between the prototype and production Veyrons are slight, but noticeable marks include the addition of marker lights or reflectors on the front fenders and a more pronounced "dorsal spine" on the hood (reminiscent of the Bugatti Atlantic), especially near the windshield.
Six Veyrons were sold at the 2005 Dubai Motor Show in December, reportedly including the demonstration models used on the stands there. These would be the first reported private sales of the car.[1]
[edit] Sales and service
Bugatti originally planned to build 300 Veyrons over five years. In March 2006, Bugatti president Bscher claimed to have 70 firm orders, selling out 14 months of production. In response, the company is reportedly speeding up production, with all 70 cars expected to be built in 2006. Bscher also reported that 14 cars have been completed. It is not clear how many are in the hands of customers. Recent media reports indicate that over 165 of the 300 cars to be produced have been sold and over 60 have been delivered to customers as of February, 2007.
Potential buyers based in and around the London area can expect VIP treatment, one buyer (a freelance writer Arash Farboud) wrote in a column for Lusso Magazine: "Dominic Lancaster, the head of Jack Barclay Bugatti in London, arranged for a private jet to take my wife and I over to the factory at Molsheim, in the top right hand corner of France."[2]
Maintenance will be possible at Bentley dealerships, but repair service will require a flown-in mechanic, who the company promises will be available 24 hours a day.
[edit] Pur Sang special edition
On 10 September 2007 a special version of the Veyron called the Bugatti EB 16.4 Veyron "Pur Sang" was unveilled at the Frankfurt Motor Show. The difference to a standard Veyron is the body finishing: the Pur Sang has none. Instead it reveals the Veyrons aluminium-carbonfibre body. Pur Sang is French, meaning thoroughbred or pure blood (literally). Production will be limited to 5 cars. Bugatti has announced that all 5 cars sold within 24 hours of the debut.[3][4]
[edit] Specifications
The Veyron features a W16 engine—16 cylinders in 4 banks of 4 cylinders, or the equivalent of two narrow-angle V8 engines mated in a "W" configuration. Each cylinder has 4 valves, for a total of 64, but the narrow V8 configuration allows two camshafts to drive two banks of cylinders so only 4 camshafts are needed. The engine is fed by four turbochargers, and it displaces 8.0 L (7,993 cc/488 in³) with a square 86 by 86 mm bore and stroke.
Putting this power to the ground is a dual-clutch DSG computer-controlled manual transmission with 7 gear ratios via shifter paddles behind the steering wheel boasting an 8 ms shift time. The Veyron can be driven by full automatic transmission. The Veyron also features full-time all-wheel drive based on the Haldex system. It uses special Michelin run-flat tires designed specifically for the Veyron to accommodate the vehicle's top speed.
Curb weight is estimated at 1890 kg (4,160lb). This gives the car a power to weight ratio of 529 bhp/tonne.
The car's wheelbase is 2710 mm (106.3 in). Overall length is 4462 mm (175.8 in). It measures 1998 mm (78.7 in) wide and 1206 mm (47.5 in) tall.
The Bugatti Veyron has a total of 10 radiators.[5]
- 3 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.
- 1 hydraulic oil radiator for the spoiler
[edit] Performance

According to Volkswagen, the final production Veyron engine produces between 1020 and 1040 metric hp (1006 to 1026 SAE net hp)[citation needed], so the car will be advertised as producing "1001 horsepower" in both the US and European markets, making it the second most powerful road production car.
Top speed was initially promised to be 406 km/h (252 mph), but test versions were unstable at that speed, forcing a redesign of the aerodynamics. In May 2005, a prototype Veyron tested at a Volkswagen track near Wolfsburg, Germany, and recorded an electronically limited top speed of 400 km/h (249 mph). In October, 2005, Car and Driver magazine's editor Csaba Csere test drove the final production version of the Veyron for the November 2005 issue. This test, at Volkswagen's Ehra-Lessien test track, reached a top speed of 407.5 km/h (253.2 mph). The top speed was verified once again by James May on Top Gear, again at Volkswagen's private test track, when the car hit 407.9 km/h. When getting close to the top speed during the test he said that "the tyres will only last for about fifteen minutes, but it's OK because the fuel runs out in twelve minutes." He also gave an indication of the power requirements, at 249 km/h (155 mph) the Veyron was using approximately 270 BHP (201 kW), but to get to its rated 407 km/h (253 mph) top speed required far more from the engine. Aerodynamic friction or drag is proportional to the square of the speed. That means going any given distance, the engine must do 4 times as much work. But going twice as fast, the engine must do that work in half the time. Therefore, to go twice the speed, you need eight times the power. The Bugatti website confirms that, on 19 April 2007, in a company test, the Veyron had an average top speed of 408.47 km/h, or 253.81 mph.[6]
The Veyron is the quickest production car to reach 100 km/h (62 mph) with a proven time of 2.5 seconds. It reaches 60 mph in approximately 2.46 seconds. It also reaches 200 and 300 km/h (124 and 186 mph) in 7.4 and 16.7 seconds respectively. And according to the February 2007 issue of Road & Track Magazine, the Veyron accomplished the quarter mile in 10.2 seconds at a speed of 142.9 mph. Other tests, however, have the Veyron hitting 150 mph in 9.8 seconds (see below), so the quarter mile time is actually faster, making the Veyron the quickest and fastest production car in history. It also consumes more fuel than any other production car, using 40.4 L/100 km (5.82 mpg) in city driving and 24.1 L/100 km (10 mpg) in combined cycle. At full throttle, it uses more than 125 L/100 km (2.1 mpg), which would empty its 100 L (26.4 gallon) fuel tank in just 12.5 minutes. The car's everyday top speed is listed at 375 km/h (233 mph). When the car reaches 220 km/h (137 mph), hydraulics lower the car until it has a ground clearance of about 8.9 cm (3½ inches). At the same time, the wing and spoiler deploy. This is the "handling" mode, in which the wing helps provide 3425 newtons (770 pounds) of downforce, holding the car to the road.[5] The driver must, using a special key (the "Top Speed Key"), toggle the lock to the left of his seat in order to use the maximum speed of 408.47 km/h (253.81 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 close and the ground clearance, normally 12.4 cm (4.9 inches), drops to 6.6 cm (2.6 inches).
The Veyron's brakes utilize unique cross-drilled and turbine-vented carbon rotors, which draw in cooling air to reduce fade. Each caliper has eight[5] titanium pistons. Bugatti claims maximum deceleration of 1.3 g on road tires. Prototypes have been subjected to repeated 1.0 g braking from 194 to 50 mph (312 to 80 km/h) without fade. With the car's fearsome acceleration from 50 to 194 mph (80 to 312 km/h), that test can be performed every 22 seconds. At speeds above 124 mph (200 km/h), the rear wing also acts as an airbrake, snapping to a 70-degree angle in 0.4 seconds once brakes are applied, providing 0.5 g (4.9 m/s²) of deceleration.[5] Bugatti claims the Veyron will brake from 400 km/h (250 mph) to a standstill in less than 10 seconds.[5] The braking is also so evenly applied that the car will not deviate from a straight path if the driver lets go of the steering wheel, even with the brakes fully applied starting from close to top speed.
