The Porsche 550 is a racing sports car produced by Porsche from 1953 until 1956. In that time only 90 Porsche 550s were produced, and they quickly established dominance in the 1.1- and 1.5- liter classes. The Porsche 550 is a mid-engine car with an air-cooled four-cylinder engine, following the precedent of the 1948 Porsche 356/1 prototype designed by Ferry Porsche. The mid-engine racing design was further developed with Porsche's 718 model; its advantages led to it becoming the dominant design for top-level racing cars by the mid-1960s.
NSU Motorenwerke AG, or NSU, was a German manufacturer of automobiles, motorcycles and pedal cycles, founded in 1873. Acquired by Volkswagen Group in 1969, VW merged NSU with Auto Union, creating Audi NSU Auto Union AG, ultimately Audi. The NSU name is an abbreviation of "Neckarsulm Strickmaschinen Union".
A U engine is a piston engine made up of two separate straight engines placed side-by-side and coupled to a shared output shaft. When viewed from the front, the engine block resembles the letter "U".
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.
Delage is a French luxury automobile and racecar company founded in 1905 by Louis Delâge in Levallois-Perret near Paris; it was acquired by Delahaye in 1935 and ceased operation in 1953.
All American Racers is an American-licensed auto racing team and constructor based in Santa Ana, California. Founded by Dan Gurney and Carroll Shelby in 1964, All American Racers initially participated in American sports car and Champ Car races as well as international Formula One events with cars named Eagle. The Formula One team, based in the United Kingdom and using British-built Weslake engines was named Anglo American Racers. Under team manager Bill Dunne they set up shop in Rye, East Sussex. The team were adjacent to Harry Weslake's engine development plant and half a mile from Elva cars. They participated in 25 Grands Prix, entering a total of 34 cars.
The Auto Avio Costruzioni 815 was the first car to be fully designed and built by Enzo Ferrari. Legal issues with former associates Alfa Romeo prevented Ferrari from creating the Ferrari marque. The 815 raced at the 1940 Brescia Grand Prix, where both entries failed to finish due to engine problems. One of the cars was later scrapped, while the other is currently in a car collection in Italy.
Caleb Smith Bragg was an American racing driver, speedboat racer, aviation pioneer, and automotive inventor. He participated in the 1911, 1913 and 1914 Indianapolis 500. In speedboat racing, Caleb won three consecutive APBA Challenge Cup races in Detroit from 1923 to 1925. He was a co-inventor of the Bragg-Kliesrath brake.
The Eagle Mk1, commonly referred to as the Eagle T1G, was a Formula One racing car, designed by Len Terry for Dan Gurney's Anglo American Racers team. The Eagle, introduced for the start of the 1966 Formula One season, is often regarded as being one of the most beautiful Grand Prix cars ever raced at the top levels of international motorsport. Initially appearing with a 2.7L Coventry Climax inline 4-cylinder engine, the car was designed around a 3.0L Gurney-Weslake V12 which was introduced after its first four races. In the hands of team boss Gurney, the Eagle-Weslake won the 1967 Belgian Grand Prix, making Dan Gurney only the second driver at the time, and one of only three to date, to win a Formula One Grand Prix in a car of their own construction. Excluding the Indianapolis 500, that win in Belgium still stands as the only win for a USA-built car as well as one of only two wins of an American-licensed constructor in Formula One. It was also the first win for an American constructor in a Grand Prix race since the Jimmy Murphy's triumph with Duesenberg at the 1921 French Grand Prix.
The 1927 Grand Prix season was the third AIACR World Manufacturers' Championship season and the second run to a 1.5-litre engine limit. In a dominant display, the championship was won by Delage, with team driver Robert Benoist winning four of the five Grand Prix.
The 1911 Grand Prix season consisted of Grand Prix races in the United States and Europe. It was a significant year as European racing gradually came out of the doldrums. A Grand Prix was held in France again. The first Indianapolis 500 was held at Indianapolis Motor Speedway, joining the American Grand Prize as a leading race.
The 1912 Grand Prix season saw Grand Prix motor racing in Europe and the United States. The growing economic confidence and interest from car manufacturers saw bigger fields and more races in the season. The French Grand Prix was held for the first time since 1908 and staged at Dieppe. The American Grand Prize was held in Milwaukee, moving from its previous home in Savannah.
The 1914 French Grand Prix was a Grand Prix motor race held at Lyon on 4 July 1914. Hailed as one of the greatest races of the twentieth century, it was a contest between the French Peugeots and the German Mercedes. For the first time, the Grand Prix was run to an engine limitation – of 4.5L maximum capacity. It was won by the Mercedes of Christian Lautenschlager who won at an average speed of 105.7 km/h (65.7 mph) after a tense seven-hour contest with the Peugeot of Georges Boillot.
The 1913 Grand Prix season consisted of Grand Prix races in Europe and the United States. Once again, the Peugeot works cars were the team to beat, continuing their success. This year the French Grand Prix was held in Amiens. The ACF introduced a fuel-economy formula for the race to discourage bigger-engined cars. Peugeot drivers Georges Boillot and Jules Goux claimed a 1-2 victory for the company after Zuccarelli had been killed in practice.
The 1922 Grand Prix season had several notable events during the year. The AIACR governing body brought in a 2-litre formula for Grand Prix. French companies brought out straight-8 engines for their cars but it was FIAT's 6-cylinder engine that took the trophies. Veteran Felice Nazzaro won the French Grand Prix, held near Strasbourg. It was a tainted victory though, as Nazzaro's nephew was killed when his FIAT's suspension broke in the latter stages of the race. An almost identical accident also happened to team-mate Pietro Bordino, though he was only slightly injured. Pierre de Vizcaya's Bugatti finished second, nearly an hour behind.
The 1923 Grand Prix season was part of a watershed year for motor racing that saw significant advances in motor-racing engineering, design and events. Fiat's chief designer, Guido Fornaca, developed the 805, the first supercharged car to win a Grand Prix. Benz appeared with the first mid-engined racer and, along with Bugatti and Voisin, produced some of the first efforts at aerodynamics on racing cars. With the United States also adopting the 2-litre formula, Harry Miller could use the smaller engine size to design the first single-seater race-car, ideally suited to American oval racing.
The 1924 Grand Prix season saw Grand Prix motor racing spread further across Europe and North America. In Italy a number of new open-road events were held. In France two new circuits were opened – at Montlhéry near Paris and Miramas near Marseille.
Alessandro Umberto Cagno, Umberto Cagno, nicknamed Sandrin was an Italian racing driver, Aviation pioneer and powerboat racer.
Ernest Henry was a mechanical engineer. He developed auto racing engines, and is especially well known for his work for Peugeot and Ballot, who dominated Grand Prix auto racing from 1912 to 1921. His engine design directly influenced Sunbeam Racing cars as early as 1914; the 1921 Grand Prix Sunbeams owe much to his work with Ballot and the 1922 Grand Prix Sunbeams were designed by him.
The Fiat 130 HP is a Grand Prix racing car made by Fiat in 1907 to a design by Giovanni Enrico. Built solely for Grand Prix motor racing, the Fiat 130 HP included new design features, such as overhead valves and hemispherical compression chambers.
