In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
English Racing Automobiles (ERA) was a British racing car manufacturer active from 1933 to 1954.
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 car 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 41, better known as the Royale, is a large luxury car built 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 vehicles in the world.
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 Alfa Romeo 6C name was used on road, race, and sports cars produced between 1927 and 1954 by Alfa Romeo; the "6C" name refers to the six cylinders of the car's straight-six engine. Bodies for these cars were made by coachbuilders such as James Young, Zagato, Touring Superleggera, Castagna, and Pinin Farina. Beginning in 1933 there was also a 6C version with an Alfa factory body, built in Portello. In the early 1920s Vittorio Jano received a commission to create a lightweight, high performance vehicle to replace the Giuseppe Merosi designed RL and RM models. The car was introduced in April 1925 at the Salone dell' Automobile di Milano as the 6C 1500. It was based on Alfa's P2 Grand Prix car, using a single overhead cam 1,487 cc in-line six-cylinder engine, producing 44 horsepower. In 1928 the 1500 Sport was presented, which was the first Alfa Romeo road car with double overhead camshafts.
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 CTA-Arsenal is a French racing car which was developed by the Centre for the study of car and cycle technology then abbreviated as CTA but today renamed as the UTAC and constructed by Arsenal at Châtillon. Two cars were eventually built. The car was intended as the French “national single seat racing car” to compete against Alfa Romeo but the project was abandoned because the car proved incapable of finishing the races in which it was scheduled to appear.
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.
Bugatti made a series of Grand Prix, and later Formula One, straight-8 racing engines; between 1922 and 1939, and once again in 1956.
The Bugatti Type 51 Dubos Coupe is a one-off automobile originally built by Bugatti in 1931 as an open-top Bugatti Type 51 race car that was driven by legendary racer Louis Chiron, and then modified by Louis Dubos to be a luxury road coupe. It is one of the most valuable cars in the world, estimated at around $20 million dollars as of 2023.
The Cooper T23, formally called the Cooper Mk.II, is a Formula 2 racing car, built, designed, and developed by British manufacturer Cooper Cars in 1953. It also competed in Formula One, in 9 Grand Prix between 1953 and 1956. It was powered by the Bristol six-cylinder 2-litre engine.
The McLaren M1A, and its derivatives, the McLaren M1B and the McLaren M1C, are a series of mid-engined Group 7 sports prototype race cars built by McLaren, between 1963 and 1968. The M1A was the team's first self-designed and developed sports car. Later versions, such as the 'M1B' and 'M1C', competed and raced in the North American Can-Am series, starting in 1966 season. The car was raced in North America and Europe in 1963 and 1964 in various Group 7 and United States Road Racing Championship series events. 24 examples of the M1A and M1B were built, and 25 examples of the M1C were manufactured. They were powered by a few different motors, including Chevrolet small-block engine, an Oldsmobile V8 engine, a Chevrolet big-block engine, and even a Ford FE engine. It was constructed out of a tubular space frame chassis, and, combined with its light weight of 551 kg (1,215 lb) this gave it a great power-to-weight ratio. The 4.5 L (270 cu in) Oldsmobile V8 engine developed around 310 hp (230 kW), while the 350 cu in (5.7 L) Chevrolet small-block V8 engine was capable of developing over 550 hp (410 kW), and 538 lb⋅ft (729 N⋅m) of torque. This drove the rear wheels through a Hewland L.G.500 four-speed manual transmission.
The Maserati 4CM is an open-wheel Grand Prix motor racing car, designed, developed and built by Italian manufacturer Maserati, in 1931.
The Maserati 6C 34 is a 750 kg open-wheel Grand Prix race car, designed, developed and built by Maserati from 1934 to 1935.
The Maserati Tipo V4 was a grand tourer-style torpedo car, designed, developed, and built by Italian manufacturer Maserati, between 1929 and 1932. It was also notably the first production car to be powered by a V-16 engine.
