A multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing, and with more smaller valves may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
The early Bugatti 8-cylinder line began with the 1922 Type 30. The same basic design was used for the 1926 Type 38 as well as the Type 40, Type 43, Type 44, and Type 49.
The Bugatti Type 57 and later variants was a grand tourer built from 1934 through 1940. It was an entirely new design created by Jean Bugatti, son of founder Ettore. A total of 710 Type 57s were produced.
The Bugatti Type 13 was the first true Bugatti car. Production of the Type 13, and later Types 15, 17, 22, and 23, began with the company's founding in 1910 and lasted through 1920, with 435 examples produced. Most road cars used an eight-valve engine, though five Type 13 racers had 16-valve heads, some of the first ever produced. The road cars became known as pur-sang ("thoroughbred") in keeping with Ettore Bugatti's feelings for his designs.
The Bugatti Type 35 is an iconic race car design produced by Bugatti at their Molsheim premises between 1924 and 1930. It was extremely successful when raced by the factory works team. It was also bought by a diverse roster of privateer clientele from around the world. It pioneered the concept of a holistically conceived, race-ready car available for purchase.
The Bugatti Type 41, better known as the Royale, is a large luxury car built by Bugatti from 1927 to 1933, With a 4.3 m (169.3 in) wheelbase and 6.4 m (21 ft) overall length, it weighs approximately 3,175 kg (7,000 lb) and uses a 12.763 litre (778 cu in) straight-eight engine. For comparison, against the Rolls-Royce Phantom VII, the Royale is about 20% longer, and more than 25% heavier. This makes the Royale one of the largest cars in the world. Furthermore, with the limited production run and the premium nature of the vehicle, it is also both one of the rarest and most expensive.
The Ferrari F1-2000 was the Formula One racing car with which the Ferrari team competed in the 2000 Formula One World Championship. The chassis was designed by Rory Byrne, Giorgio Ascanelli, Aldo Costa, Marco Fainello, Nikolas Tombazis and James Allison with Ross Brawn playing a vital role in leading the production of the car as the team's Technical Director and Paolo Martinelli assisted by Giles Simon leading the engine design and operations. The car was a direct development of the F300 and F399 from the previous two seasons, using the same basic gearbox and a new engine with a wider V-angle ; this new wider angle improved and lowered the centre of gravity of the car. It also featured improved aerodynamics over the F399 most noticeably a flatter underside of the nose area, which put it on par with that year's McLaren MP4/15.
The 1935 Grand Prix season was the second year of the new 750 kg Formula. The success of the previous year encouraged the AIACR to reinitiate the European Championship. It was composed of the seven national Grands Prix and was won by Rudolf Caracciola, driving for the Mercedes-Benz team. The team dominated the season winning five of those Grand Épreuves, as well as four of the other major races of the season. However, in one of the great motor-races in sporting history, Tazio Nuvolari in a Scuderia Ferrari Alfa Romeo beat the combined numbers of the German teams in their home Grand Prix. The season also saw the arrival on the international stage of the bright young talent Bernd Rosemeyer in the Auto Union team.
The 1931 Grand Prix season was a watershed year, with the advent of the AIACR European Championship. After several years of Grand Prix racing in the doldrums with little technical development, 1931 saw new models come from all three main manufacturers: Bugatti, Maserati and Alfa Romeo.
The 1932 Grand Prix season marked the second year of the AIACR European Championship. It saw the debut of Alfa Romeo's sensational new Tipo B and with it, Tazio Nuvolari won the Championship driving for the Alfa Corse works team. The 40-year old Nuvolari won two of the three rounds and was second in the other. Still running to a Formula Libre rules for the cars, the regulations were revised to set the races to be between five and ten hours. However, all three national committees ran their races to the minimum time-limit.
The 1933 Grand Prix season was an intermediate year, as it would be the last season for the current AIACR regulations before a new weight-formula was introduced in 1934. As such, the European Championship was not held and the manufacturers held back on further developments of their existing models. Alfa Romeo, following an Italian government financial bailout and like Mercedes-Benz the previous year, had shut down its Alfa Corse works team. Scuderia Ferrari, their regular customer team took up the role of racing Alfa Romeos and a number of ex-works drivers moved across to join their ranks. They were not allowed, however, to buy the impressive Tipo B that had been so dominant in the previous season.
The 1934 Grand Prix season saw the advent of the new 750 kg Formula. In an effort to curb the danger of rising speeds, the AIACR imposed this upper weight limit that effectively outlawed the large capacity engines. The incumbent manufacturers Alfa Romeo, Maserati and Bugatti had been preparing their new models with varying success – the best of which was the Alfa Romeo Tipo B. However, it was the state-sponsored arrival of the two German teams, Mercedes-Benz and Auto Union, and their innovative and progressive cars that ignited a new, exciting era of motor racing.
The Lotus 69 was an open-wheel formula racing car developed by Lotus in 1969 for use in Formula 2, Formula 3, and Formula Ford.
