1946 abandoned the 3.0L supercharging rule and introduced the A and B equations (later the first and second equations). Formula A allows the use of the old 4.5L ordinary aspirated engine car, but because the performance of the 3.0L supercharged engine is higher than the former (and the German and Italian cars before the war are not allowed to use it), in order to balance the performance of different cars, the 3.0L supercharged engine was replaced by the 1.5L supercharged engine used in the previous voiturette competition. Since then, there have been no low-performance car races under Class A/Formula One, so Formula Two (formerly known as Formula B) was officially established as a smaller and lower-cost race by the FIA in 1948, which became a supplement to the grand prix in this period.
Formula two racing cars use smaller engines and less power than formula one racing cars, and the racing cars used are smaller, lighter and cheaper than its big brother. It is allowed to use 2L ordinary aspirated engine or 750cc supercharged engine (the latter is basically not used). This attracted some new manufacturers, such as Cooper, to participate in Formula 2 racing instead of competing with big manufacturers such as Alfa Romeo and Maserati. In fact, Formula One was very expensive at the beginning, and there were very few contestants, so that 1952 and 1953 international grand prix competitions were held in Formula Two. (However, top non-champion events will still be held. For example, the Indianapolis 500 is part of the world championship between 1950 and 1960, but it has its own rules and has never been a formal Formula One race. ) 1.5L Porsche 7 18
Due to the popularity of small-capacity racing cars,1954f1started to use 2.5L engines, which led to the gradual decline of F2' s attention. However, it changed the rules and introduced the car with 1.5L engine at 1957. The race was gradually dominated by the rear engine developed by Cooper based on its Formula Three racing car and "short tail" racing car and the RSK racing car developed by Porsche. Ferrari developed Dino 156 from scratch as F2 racing car, which was also used as other pre-engine grand prix racing cars. The dominant engine in this formula one is Coventry-Cramer FPF four-cylinder engine, equipped with Borgward 16 valves.
Cooper made several improvements to his F2 car, and won the first sub-station championship of F 1 in 1958, marking the arrival of the post-engine era of F 1. The equation of 1.5L didn't last long, and was soon replaced by the juvenile equation of 1963, which had previously replaced F3-but the first-order equation of 196 1 well continued the tradition of the second-order equation.
[Editor] Intermittent period of youth equation (1961–1963) and quadratic equation (1964–1966)
Youth Formula was launched on 1959, which is a wide-ranging competition for the general public-it not only undertakes the task of F3 as a formula training competition, but also replaces F2 as a high-level international competition second only to F 1. People soon realized that these two roles must be separated, so in the 1964 season, the F2 and F3 competitions resumed operation. Among them, F3 uses a commercial engine of 1L, which can make very limited changes (much like FJ), while F2 uses an engine of 1L capacity, but it is completely designed for racing cars. F2 is mainly the domain of f 1 stars on rest days. At this time, most engines were provided by Cosworth (the cylinder block of Ford) and Honda, but some other engine units began to appear, such as various Fiat-based units and special engines provided by BMC and BRM.
[Edit] 1.6L period and driver classification (1964- 197 1)
Jochen Rindt drives a Lotus Formula 2 car at the New Boglin circuit, 1970.
In the late 1960s, with the slogan of Formula One "Return to Power" put forward, the gap between F 1 and F2 obviously widened. Therefore, in order to maintain the racial status of f 1, F2 introduced a new commercial engine specification of 1600cc. The most popular 1600cc engine is Cosworth FVA, which is equipped with 16 valve on the four-cylinder Cortina cylinder block, which is the "proof of concept" of the legendary DFV. 1967 FVA(3.373 x 2.72 inches) engine can reach 220 bhp at 9000 rpm. There are also some other engine units, such as BMW four-cylinder and V6DinoFerrari engine.
In addition, many Formula One drivers are used to driving this smaller and lighter car on weekends other than race days, and some grand prix sub-stations (especially the German Grand Prix, the longer New Boglin circuit can accommodate multiple drivers at the same time) allow Formula One and Formula Two cars to race in the same race. Jacky Ickx made his debut in a Formula Two car and finished fifth after qualifying. Although still lagging behind Formula One cars, Ickx quickly surpassed those slower cars and won a competitive position in points, but unfortunately, it retired due to suspension system failure. More unfortunately, jim clark, considered as one of the greatest racers in history, died in an accident at Hockenheim on 1968.
1967, FIA launched the European Formula Two Championship. Ickx won the first championship of Matra MS5 ahead of the second Australian Frank Gardner by 1 1.
Formula One drivers "invaded" Formula Two (similar to Buschwhacking and NASCAR today) and were recognized by the unique classification system adopted at that time. Any driver who doesn't reach the "A" level can't get the championship points, but he can get the "A" level evaluation in many ways (the regulations change every year), such as getting points in two grand prix events or getting the top three positions in two world sports car events. Formula One annual champion can get an "A" rating for one year, while Formula One world champion can keep it for five years. This system can encourage inexperienced drivers to fight for the championship and career goals, and at the same time, it can also allow experienced drivers to practice hard even between two grand prix events with a long interval.
In the early days of this formula system, Braham and Lotus were the most famous manufacturers, and Ferrari would participate in a working group intermittently, similar to BMW (using Lola and Dornier as the chassis). In addition, a large number of small manufacturers such as Chevron and GRD also provide racing cars.
March-BMW 1978 driven by Peter Shaman, the formula rules allow the use of a 2.0-liter commercial engine to improve horsepower. Cosworth BD series and BMW four-cylinder engines dominated in the first few years of the race, and then the Marches team using BMW engines gradually took over the race. 1976, engines developed purely for competition were allowed to appear on the field, and Renault also developed a powerful V6 engine. Thanks to the sponsorship with gasoline dealer Elf, Formula One racing was monopolized by French teams and drivers in a short time. BMW began to cooperate with the March team in the late 1970s and established a solid relationship. Even the Ferrari engine had a brief return and won a small victory. The Hart 420R, which was upgraded from Cosworth BDA, was a success in the Marches car race, but it was not the best partner of Toleman team. The chassis with obvious advantages in this issue comes from March and Ralt. At the same time, Chevron, French Elf and Martini, as well as German maurer, also shined on the field.
Honda announced its return with a powerful V6 engine in the early 1980s. However, this kind of engine proved to be very impractical, and the cost of competing with Ralt-Honda also hit Shui Piao. Therefore, the minimization of grid size and the decline of interest in this series threaten its enthusiasm. Main entrance: World Formula Two Championship.
After disappearing for 25 years, the FIA announced on June 25, 2008 that the name f 1 would reappear in the public eye in 2009.
According to the fax vote of the FIA World Motor Sports Council, motorsport Vision (MSV) was approved to provide chassis and engines for the new World Formula Two Championship. According to part of the tender, MSV can also become the founder of the championship and the operating agency of all racing cars.
The whole competition includes 8 races in Europe, lasting from May to 1 1 month. There are two games every weekend. The car travels 1 10 km (about 40 minutes) every race, and there will be a forced stop in the second race. Before each game, there will be two 30-minute practice matches and two 30-minute qualifying matches. There will be three formal practice days throughout the season. The first practice day is arranged before the first game, and the other two are in the season. A maximum of 300 kilometers of test mileage is allowed on the practice day. The test may be arranged on the test track of Bedford Circuit in MSV. Or, the test rules may be changed, allowing 50 kilometers of test drive before each competition, and the maximum test mileage allowed for the whole 2009 season is 1000 kilometers. )
The car was designed by Williams and prepared by MotorSport Vision (MSV). The open-wheel chassis (with wheels outside the vehicle body) will be driven by the Audi 1.8L turbocharged engine developed by Mountune Racing. The goal of F2 new car is to be between F 1 and F3 in performance. MSV belongs to former Formula One driver jonathan parr Palmer, who also runs the Palmer Formula Audi Series and the British Super Motorcycle Championship. Henry Surtees's death in the fourth round of Brandt Zazie defiled the game.
