The Bugatti
Veyron EB 16.4 is a mid-engined grand touring car. The Super Sport version is
the fastest road-legal production car in the world, with a top speed of
431 km/h (268 mph). The
original version has a top speed of 408.00 km/h (253.52 mph). It was namedCar of the Decade (2000–2009) by the BBC television programme Top Gear.
Designed and developed by Volkswagen Group (based on the Bentley Hunaudieres concept) and produced by Bugatti Automobiles
SAS at their
headquarters in Château Saint 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 former Peterbilt Trucks
engineer and now Bugatti Engineering chief Wolfgang Schreiber. Though
commissioned by Volkswagen, this car is only sold through the Bugatti
manufacturers and cannot be found at any Volkswagen dealer.
A number of special variants have been produced,
including two targa tops. In December 2010, Bugatti began
offering prospective buyers the ability to customize exterior and interiors
colours by using the Veyron
16.4 Configurator application
on the marque's official website.
Name origin
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. The 16.4 refers to 16
cylinders and 4 turbochargers.
Specifications and performance
The Veyron's quad-turbocharged W16 engine
The Veyron features an 8.0 litre,
quad-turbocharged, W16 cylinder engine, equivalent to two narrow-angle V8 engines .
Each cylinder has four valves for
a total of sixty four, but the narrow staggered V8 configuration allows two overhead camshafts to drive two banks of cylinders so
only four camshafts are
needed. The engine is fed by four turbochargers anddisplaces 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 transmission is a dual-clutch direct-shift gearbox computer-controlled automaticwith
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- or fully automatic mode. A replacement transmission for the Veyron
costs just over US$120,000. It also has permanent four wheel drive using the Haldex Traction system. It uses special MichelinPAX run-flat tyres, designed specifically to
accommodate the Veyron's top speed, which cost US$25,000 per set. The tyres can be removed from
the rims only in France, a service which costs US$70,000. Curb weight is
1,888 kilograms (4,162 lb). This
gives the car a power-to-weight ratio, according to Volkswagen Group's figures,
of 446.3 metric horsepower (328 kW; 440 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 tenradiators:
§
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 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 drag area – the combination of drag coefficient
and frontal area, represented as CdA – of 0.74 m2 (8.0 sq ft).
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 ft·lbf) of
torque. 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) or more.
Super Sport
edition
The Veyron Super Sport features an engine power
increase from the standard 1,001 metric horsepower (736 kW; 987 bhp) to
1,200 metric horsepower (883 kW; 1,184 bhp) and torque of
1,500 N·m (1,100 ft·lbf) and a revised aerodynamic package. It was shown publicly for the first
time at the Pebble
Beach Concours d'Elegance in
August 2010.
Bugatti's official test driver Pierre Henri
Raphanel drove the Super Sport version of the Veyron on Volkswagen's Ehra-Lessien 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). Once produced
for sale, the first five Super Sports will sport the same black and orange
finish as the first production car, which was used to set the speed record, and
all production models will be electronically limited to 415 km/h
(258 mph) to protect the tyres.
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 the Ehra-Lessien test
track on 19 April 2005.
This top speed was verified by James May on Top Gear in November 2006, again at Volkswagen Group's
private 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). The Veyron has the highest top speed of any
street legal production car. Back in the Top
Gear studio, co-presenter Jeremy Clarkson commented that most super-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 (253 mph). May responded that no,
the Veyron was very controlled, and only wobbled a tiny-bit when the air-brake
deployed. May further commented “Absolutely yeah, it’s totally undramatic. But
I would give you a bit of a warning, It’s a bit disorientating doing that sort
of speed, because after I came off the banking, I was slowing down to stop, and
you know how you get a bit impatient and think ‘I’ll just open the door’,
fortunately I looked back at the speedo, and I was still doing seventy.”
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 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). 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.
In this handling mode the wing provides 3,425 newtons
(770 lbf) of downforce, holding the car to the road.
For top
speed mode the driver must,
while at rest, toggle a special top speed key to the left of the driver's seat.
A checklist then establishes 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.
The lightweight aluminium alloy monobloc brake calipers are made by AP Racing; the fronts have eight[11]titanium pistons
and the rear calipers have six pistons. Bugatti claims maximum deceleration of
1.3 g's 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 of a kilometer (third of a
mile).

Grand Sport L'Or Blanc
Teaming up with Königliche Porzellan-Manufaktur, Bugatti has
created the one-off Veyron "L'Or Blanc" . Its name means "white
gold", and the special Grand Sport uses porcelain to distinguish its body
and interior with a blue and white pattern.
Super Sport
Improved aerodynamics kit, 1,200 metric
horsepower (883 kW; 1,184 bhp) 1,500 newton metres
(1,100 ft·lbf) 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 415.07 km/h (257.91 mph) to protect the tyres from disintegrating.
The first five of an unannounced production run made its debut in a matte black
and orange colour combination, all of which have been spoken for. The public
debut was at the Pebble Beach Concours d'Elegance in August 2010. It is valued
at GB£1.7 million and Bugatti have stated that only 30 will be produced.
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 417 km/h (259 mph), 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.
16C Galibier Concept
The Bugatti 16C Galibier Concept is a prototype
of a luxury sedan which was presented officially in September by Bugatti prior
to the IAA 2009. A
derivative of the concept vehicle is expected to reach the market in 2013. The
car is a 4-door luxury sedan which shares the W16 8.0L engine of the Veyron, but
with two superchargers instead of four turbochargers for improved torque.
