Grands Prix between 1940 and 1945 occurred during World War II and so were limited to a very small number of events. There was no organised championship in these years. The majority of Grand Prix races during this period were run in America. The first post-war races were run in Paris on 9 September 1945, one week after the end of the war.

Reginald Parnell was a racing driver and team manager from Derby, England. He participated in seven Formula One World Championship Grands Prix, achieving one podium, and scoring a total of nine championship points.
The 1926 German Grand Prix was an auto race held at the AVUS track on 11 July 1926. It was the first ever German Grand Prix. The race was held in heavy rain, and was won by Germany's native son, Rudolf Caracciola.
Emilio Materassi was an Italian Grand Prix motor racing driver.
The European Drivers' Championship was an annual competition in auto racing that existed prior to the establishment of the Formula One world championship in 1950. It was established in 1931 and ran until the end of 1939 with a hiatus from 1933–34, and awarded points to drivers based on the results of selected Grand Prix races, the so-called Grandes Épreuves. The championship was discontinued because of the outbreak of World War II in 1939, and no champion was officially declared for the last season.
The 1937 Grand Prix season was the fifth AIACR European Championship season. The championship was won by Rudolf Caracciola, driving for the Mercedes-Benz team. Caracciola won three of the five events that counted towards the championship.
The 1938 Grand Prix season was the sixth AIACR European Championship season. The championship was won by Rudolf Caracciola, driving for the Mercedes-Benz team. Caracciola won one of the four events that counted towards the championship.
The 1939 Grand Prix season was the seventh AIACR European Championship season. The championship winner was never officially announced by the AIACR due to the outbreak of World War II less than two weeks after the final event in Switzerland. The Italian GP initially had been a fifth event, but it became clear well before the war that it would be cancelled due to construction work. At that time, it was also undecided which scoring system would be used, the old minimum points system that basically counted positions, or the French maximum points system similar to the modern one. Although Hermann Paul Müller would have won the championship on points according to the old system, the president of Nazi Germany's highest motorsports organisation declared Hermann Lang the champion. Lang was clearly the dominating driver in that season, which was acknowledged by the international press. In the first two of the four championship events, both Lang and Müller won once while the other failed to complete 75% of the distance. The German round saw Lang retiring early, and Müller finishing 2nd behind Caracciola. This left Müller in the lead in both scoring systems, as published in magazines, with the Swiss round deciding the outcome. Müller finished 4th behind three Mercedes, which gave him the lead in the old point system, while in front, Lang had beaten Caracciola for the lead in the maximum points system.
The 1946 Grand Prix season was the first post-war year for Grand Prix motor racing. It was notable for including the first ever race run to Formula One criteria, the 1946 Turin Grand Prix. There was no organised championship in 1946, although Raymond Sommer proved to be the most successful driver, winning five Grands Prix. Maserati's cars proved difficult to beat, winning 9 of the season's 20 Grand Prix races.
The 1947 Grand Prix season was the second post-war year for Grand Prix racing. It constituted the first full season of the FIA's Formula One motor racing, though some Grands Prix still used other formulas. There was no organised championship in 1947, although several of the more prestigious races were recognised as Grandes Épreuves by the FIA. Luigi Villoresi proved to be the most successful driver, winning six Grands Prix. Alfa Romeo's cars proved difficult to beat, winning 13 of the season's 32 Grands Prix.
The 1925 Belgian Grand Prix was a Grand Prix motor race held at Spa-Francorchamps on the 28th of June 1925. This was the first ever grand prix held at Spa, and the first ever Belgian Grand Prix.
The 1910 Grand Prix season was the fifth Grand Prix racing season. Because of the ongoing international economic recession, there were no Grandes Épreuves held. The American Grand Prize was held in Savannah.
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 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 1915 Grand Prix season saw Grand Prix motor racing continue in the United States. Racing was suspended in Europe due to the outbreak of World War I. The American Grand Prize was held in San Francisco for the first time, in conjunction with the Panama–Pacific International Exposition. Several of the latest European cars had been imported to the USA before the war started. Briton Dario Resta had a Peugeot and Ralph DePalma raced one of the Mercedes GPs. While Resta won both races at San Francisco and DePalma won the Indianapolis 500, just ahead of Resta it was Earl Cooper, running a Stutz, whose consistency gave him the unofficial AAA national championship.

It was the fifth and final race of the 1927 AIACR World Manufacturers' Championship season. The race was won by French driver Robert Benoist. It was his fourth victory from the season's five races, a performance that put the seal on his Delage team's already-unassailable lead in the Championship.
