In the 1949 International Association of Automobile Recognized Clubs -the actual International Automobile Federation- decided to establish a World Drivers Championship with the Grand Prix cars, the highest expression of motorsport in the 30s and 40s. For that he had to define a regulation based on different technical formulas. To keep the brand new competition as the reference for the tracks, it was decided to use the technical regulation called Formula 1, which allowed cars with 1.500 cm3 engines with a compressor and 4.500 with normal power.
However, this rule was not born overnight. Conversely, it was the result of an evolution that began in 1906 with the first Grand Prix in historyThat of France organized by the Automobile Club of that country. This test not only coined the term "Grand Prix", but it was the first competition that used a technical regulation to restrict the number of participants.
In that 1906 French GP, held in the area of La Sarthe and what did the hungarian win Ferenc Szisz with Renault, allowed vehicles with a maximum weight of 1.815 kilos, increasing by 815 kg the regulated volume in the first races of the XNUMXth century.
During the following years, the ACF modified the regulations, which were taken as a parameter for the rest of the Grand Prix that were held in Europe until in the 20s the AIACR took the reins of the matter.
En 1907 The French entity rejected the maximum weight system and set a fuel consumption limit of 30 liters for every 100 kilometers traveled. In 1908 it demanded engines with 155-millimeter cylinders in the four and 127 mm in the six. These conditions allowed the participation of the main brands of the time such as Brasier, Darracq, Fiat, Napier, Mercedes, Bits, Panhard, Renault, Bayard, Itala y De Dietrich.
En 1913 The consumption regime of the vehicles was varied by reducing it to 20 liters per 100 kilometers. In 1914 ACF set for the first time a cubic capacity limit of 4.500 cm3 and added a maximum weight of 1.000 kilos.
After World War I there were certain freedoms in Europe until the activity was reorganized. However, in the United States, rules were established for 500 Miles Indianapolis, which that year allowed cars with a maximum of 3.000 cm3.
En 1921 in the Old World, 1.400 cm3 was reached with a minimum weight of 350 kilos; while for the Indy 500 the limit was lowered to 2.000 cm3.
En 1925 in Europe the rules were changed again: 1.500 cm3 and 450 kilos minimum, which were reduced to 425 in 1923. This regulation lasted until 1925, when it was decided to return to two liters without weight limitation.
In the period of 1926/1927 the AIACR adopted the 1.500 cm3 formula with or without a compressor and absolute freedom of weight. However, in 1928 a free regulation was returned, something that encouraged brands to create their own official teams. Alfa Romeo y Bugatti They used two-liter engines with a compressor. Maserati, meanwhile, one of 2.500 cm3 with eight cylinders in line.
En 1931 the circuit of Monza He decided to set his own rules and divided the participants into groups: from 1.100 to 2.000 cm3, from 2.001 to 3.000 and more than 3.000. For the rest of the races, the regulations applied by the AIACR were maintained, which also accepted cars with single-seater bodywork.
En 1938 Because the engines were already too powerful and there was a lot of danger in racing, a formula based on weight-power was ruled. The displacement was limited to 3.000 cm3 with a compressor and 4.500 without this system. While the minimum weight was set at 850 kilos.
En 1941 The liter and a half formula began to be used, although as early as 1938 there were several brands with this type of specification. As the Alfa Romeo 158, known as Alfetta.
After Segunda Guerra Mundial liberties returned. The brands used old cars of all kinds. Nevertheless, in international races the regulation called Formula 1 governed: 1.500 cm3 with compressor and 4.500 with normal power. On that basis, the AIACR created the World Pilots Championship, which had its first edition in 1950 ...
