100 years of Bugatti at Concorso d'Eleganza Villa d'Este
Bugatti Automobiles Pays Homage with four special Veyron models to Ettore Bugatti's
Masterpiece: The Type 35 Grand Prix In a further highlight on this year's agenda of centennial celebrations, Bugatti Automobiles S.A.S. presented four Bugatti Veyron specials at Villa d'Este Concorso d'Eleganza. These one off models are reminders of Bugatti's glorious motor-racing history which played a central role in popularising and ultimately establishing the myth which the brand continues to enjoy to this day.
The Bugatti brand is almost inextricably linked to the Type 35. The Type 35 Grand Prix was by far the most successful racing model. The unmistakable radiator grille and eight-spoke aluminium wheels of the Type 35 have become defining features of the Bugatti automobile. In its day, the Grand Prix was also well ahead of its time in terms of engineering ingenuity. The front axle design of this vehicle, which, for reasons of weight minimisation, is hollow, is a true masterpiece of workmanship and was deemed nothing less than revolutionary. Its springs were passed through the axle to produce a high level of stability. The Grand Prix's brake drums were integrally fitted into its lightweight aluminium wheels. Únfastening the central wheel nut allowed the wheel to be easily removed within a matter of seconds and the brake to be exposed. This was a crucial advantage at the pit stop.
2000 wins in ten years 
The blue racers made their first appearance on the race track at the Grand Prix held by Automobil Club de France in Lyon in 1924. In the decade that followed, they remained practically unchallenged thanks to sophisticated manufacturing efforts, their lightweight design and easy handling. During that ten-year era, they won almost 2000 races – more than any other model ever has. Grand Prix races were highly fashionable events in those days, and Bugatti was not the only brand with considerable interest in substantiating the reputation of its products by winning races. In fact, in the 1920s, Europe was regularly host to a number of different races in different countries on a single weekend. The teams set up by different automobile manufacturers competed at popular race circuits such as Targa Florio, Le Mans, Monza and Spa as well as in Rome, Nice, Antibes and even a village in Alsace.
The main reason Bugatti won such an enormous number of races – on the back of which successes the brand was also able to forge its image – was the fact that Bugatti sold not only its normal sports and touring cars to private buyers, but its racing cars too. Thus it was that its automobiles took part in such a large number of Grand Prix events.
This bestowed upon Ettore Bugatti a double success. He was able on the one hand to sell his racing cars expensively to wealthy private buyers with a keen sporting ambition and, on the other, to capitalise on their successes on international racing circuits – without actually having to make a single investment in these 'marketing activities'. This stroke of genius by 'Le Patron' not only brought him immortal fame, but a substantial fortune as well. A total of 350 legendary Type 35-series automobiles were ultimately built – in a wide variety of versions. Those that survived their racing days, accidents, World War II and all other risks over the years, have become coveted and highly priced collectors' items.
Four Type 35 Grand Prix models – Four distinct personalities – Four Veyrons 
Tradition being what it is, the Bugatti Veyron Specials built to mark the 100th anniversary of the brand feature the racing colours of the respective countries: blue for France, red for Italy, green for England and white for Germany. Each of the four new Veyrons has a specific 'predecessor' in the form of an original Grand Prix Bugatti on which it was modelled. These four historic race cars represent the generation of legendary Bugatti Grand Prix racers which were piloted by world-famous race-car drivers and which scored countless racing victories in the 1920s and '30s. Each of the four Veyron Specials is named after a Bugatti race-car driver of the 1920s and 30s. Jean-Pierre Wimille has given the blue Veyron its name, Achille Varzi the red one, Malcolm Campbell the green one and Hermann zu
Leiningen the white Veyron.
Jean-Pierre Wimille was one of the longest-serving drivers at Bugatti. He only joined the team in Molsheim in 1933, but subsequently remained loyal to the brand, ultimately driving home Bugatti's last-ever victory in 1947 at Bois de Boulogne in a 4.7-litre Monoposto Type 59/50 B. Wimille's many previous successes included winning the 24 Hours of Le Mans in 1937 and 1939. Achille Varzi was a member of the official Bugatti team from 1931 to 1933. He had already achieved many successes since 1928 driving a private Type 35 C, then later went on to win the Monaco Grand Prix, an event on Berlin's Avus circuit and other races. As the setter of numerous world records for speed, the name Malcolm Campbell is firmly established in racing history. He also competed in countless 'normal'
races from 1911 and 1936, often piloting a Bugatti Type 39 A or Type 35, and he owned one of the legendary Type 57 S street sports cars. Prinz Hermann zu Leiningen's career driving Bugattis began in 1927 when he purchased a Type 40 chassis, for which he had a racing body built. He went on to win a number or races in a privately owned Type 37 A before eventually standing in the spotlight of the international racing scene in a 35 C for several years from 1930 onward.
'We have put a lot of effort into translating colour and material, the defining characteristics of our historic role models, into the designs of the modern-day Veyrons,' explains Alasdair Stewart, Director Sales & Marketing at Bugatti Automobiles S.A.S. 'We have taken extreme care to match the original colours of the original race cars, exterior and interior'
On Sunday, the four historic racing Type 35s and the four modern-day Centenaire EditionVeyrons will be exhibited alongside each other in the park of Villa Erba for the first and only time.
Ahead of that presentation, Bugatti will on Saturday be prominently represented in the park of Villa
d'Este by a special-display-class exhibition of models, which will serve to portray the 100-year history of the brand. Bugatti's participation in the classic Concorso d'Eleganza Villa d'Este at Lake Como will be the second highlight event to mark the carmaker's centennial celebrations after it took part in the International Geneva Motor Show in early March. This latest event will be followed by the Pebble Beach Concours d'Elegance in California in mid-August and the main celebratory event on 12 September in Molsheim (Alsace), which has been the home of this unparalleled automobile brand for 100 years.
Source - BugattiThe trials of the fastest road sports car in the world have been successfully completed. One of the most ambitious projects in automobile history is entering its production phase. The first Bugatti Veyron 16.4 cars, built mainly by hand, are already being completed and will be delivered to customers this year.
The sports car, capable of more than 400 km/h, is driven by a 16-cylinder mid-engine, that at 710 mm long is no larger than a conventional V12 unit, and due to its lightweight construction weighs only about 400 kilos. Its compact dimensions are due to the unique arrangement of its cylinder banks in a W configuration. Two VR8 blocks, each with a fifteen degree bank angle, are joined in the crankcase to form one engine. Both eight cylinders are set at an angle of ninety degrees to each other and are aspirated by a total of four exhaust gas turbochargers. The engine delivers 1001 HP at 6,000 r.p.m. and provides a maximum torque of 1250 Newton metres at between 2,200 and 5,500 r.p.m.
To apply the power of the 64-valve unit to achieve satisfactory driving dynamics both in everyday traffic and on the racetrack, the Bugatti development team of Dr. Franz-Joseph Paefgen and Dr. Wolfgang Schreiber has realized a propulsion unit that is without parallel in its complexity. If the extreme engine power is a master stroke of genius, its conversion for road use is an equally tough challenge. As Dr. Schreiber says 'For 1000 HP propulsion power, the system demands approximately 2000 HP to be additionally generated as heat energy during combustion. Half in each case is dissipated in the exhaust gas and cooling water'.
To do this, the Bugatti engine has two water circuits. The larger of the two with 40 liters of cooling water has three coolers in the front section of the car, to keep the engine at operating temperature. The second circuit, called the low-temperature system, has a separate water pump and contains 15 liters of cooling water. These are used to cool, by up to 130 degrees, the charged air, heated during compression in the turbochargers, in two heat exchangers mounted on the engine. The cooled, charged air then passes through two 'air manifolds' into the combustion chamber, which it then leaves as exhaust gas at approximately 1,000 degrees. It then passes through the turbines of the exhaust gas turbochargers. This causes the exhaust gas to expand, so that it is cooled by up to about 150 degrees, is then cleaned in the catalyzer and exhausted.
In addition to its unique compactness, the high performance of the power unit is the centrepoint of the dvelopment. Lightweight materials are used that not only result in a low power-to-weight ratio but also particularly provide the spontaneous response of the moving engine-internal masses. In addition to piston rods of titanium, the so called 'easy runners', the eight-stage oil pump integrated into the crankcase for dry sump lubrication has light aluminum gears. Because the arrangement of the 16 cylinders ensures extremely quiet running, only a small flywheel is needed. The use of motor sport technology is evident not only from the plasma-coated running faces of the cylinders but also by the use of high-strength steel for the shafts and gears in the aluminum crankcase.
Únique in engine design is the integration of knock and misfiring detection in an ion current system. Because the multiplicity of cylinders means very quiet running and ensures that the velocity difference will be extremely small in the event of a cylinder misfire, cylinder-selective detection by measuring rough running is not reliable enough. Therefore, Bugatti Ion Current Sensing (BIS) is used. The ion current flowing at each spark plug at the timepoint of ignition is monitored by a separate evaluation sensor system. The data obtained is passed to both engine control units. If knocking combustion or a misfire is detected, the associated control unit immediately initiates countermeasures, such as retardation of the ignition timepoint, shutdown of the cylinder or reduction of the charge pressure. According to the head of Bugatti Únit Development Gregor Gries, 'The aim of our technology is
to generate the maximum performance from the engine in a stable, clean manner'.
The power generated in the engine is transferred to the flange-mounted direct manual gearbox (DSG). The torque and speed is then transmitted, through the gearing of seven forward and one reverse gear, via a universal drive to the front axle gearbox and via a second universal drive, along the right side of the engine to the rear axle gearbox. Both the DSG and both axle gearbox housings are of lightweight aluminum construction. The drive power is distributed to the front and rear axles by means of a Haldex coupling, an actively-controlled multi-disk, inter-axle lock directly connected to the front axle gearbox. The following front axle differential distributes the power to both front wheels. In the rear axle differential the power is distributed to the rear wheels via a bevel gear and a further differential. In addition, an actively-controlled, hydraulically-actuated, multi-disk differential lock is installed here. When necessary, it prevents speed differences between the rear wheels and ensures optimum directional stability when accelerating and when cornering under load. All load distribution functions are completely automatic and are undetected by the driver.
The Bugatti marque has since earliest times been regarded as a central force in the advancement of automobile development by innovative solutions. A position deservedly maintained by the first high-performance sports car of the modern Bugatti.
