'''Formula Three''' ('''F3''') is a third-tier class of [[open wheel car|open-wheel]] [[formula racing]]. The various championships held in Europe, Australia, South America and Asia form an important step for many prospective [[Formula One]] drivers.

==History==
{{More citations needed section|date=April 2022}}
[[Image:Effyh500-front.jpg|thumb|A typical early car, the [[Effyh 500]] (1947–1952) was built in Malmö, Sweden and was one of the more successful cars. It had a lightweight tube chassis, aluminium bodywork and was powered by a 500cc 1-cylinder JAP engine.]]
Formula Three (adopted by the [[Fédération Internationale de l'Automobile|FIA]] in 1950) evolved from [[postwar]] [[auto racing]], with lightweight tube-frame [[chassis]] powered by 500 cc [[motorcycle]] engines (notably [[Norton (motorcycle)|Norton]]s and [[JA Prestwich Industries Ltd|JAP]] speedway). The 500 cc formula originally evolved in 1946 from low-cost "special" racing organised by enthusiasts in [[Bristol]],  England, just before the [[World War II|Second World War]]; British motorsport after the war picked up slowly, partly due to petrol rationing which continued for a number of years and home-built 500 cc cars engines were intended to be accessible to the "impecunious enthusiast". The second post-war motor race in Britain was organised by the [[VSCC]] in July 1947 at RAF Gransden Lodge, 500cc cars being the only post-war class to run that day. Three of the seven entrants were non-starters, and, of the four runners, all but one retired on the first lap, leaving [[Eric Brandon]] in his [[Cooper Car Company|Cooper]] Prototype (T2) trailing round to a virtual walk-over at an average speed of {{cvt|55.79|mph|km/h|abbr=on}}, though his best lap (which was the fastest recorded for any 500) was {{cvt|65.38|mph|km/h|abbr=on}}.{{citation needed|date=September 2020}}

Cooper came to dominate the formula with mass-produced cars, and the income this generated enabled the company to develop into the senior categories. Other notable marques included [[Kieft Cars|Kieft]], JBS and [[Emeryson]] in England, and Effyh, Monopoletta and Scampolo in Europe. John Cooper, along with most other 500 builders, decided to place the engine in the middle of the car, driving the rear wheels. This was mostly due to the practical limitations imposed by chain drive but it gave these cars exceptionally good handling characteristics which eventually led to the mid-engined revolution in single-seater racing.

The 500cc formula was the usual route into motor racing through the early and mid-1950s (and stars like [[Stirling Moss]] continued to enter selected F3 events even during their GP careers).  Other notable 500 cc Formula 3 drivers include [[Stuart Lewis-Evans]], [[Ivor Bueb]], [[Jim Russell (racing driver)|Jim Russell]], [[Peter Collins (racing driver)|Peter Collins]], [[Don Parker (racing driver)|Don Parker]], [[Ken Tyrrell]], and [[Bernie Ecclestone]].

From a statistical point of view, Parker was the most successful F3 driver. Although coming to motor racing late in life (at age 41 in 1949), he won a total of 126 F3 races altogether, and was described by ''[[Motor Sport (magazine)|Motor Sport]]'' magazine (in his 1998 obituary) as "the most successful Formula 3 driver in history". Although [[Stirling Moss]] was already a star by 1953, Parker beat him more than any other driver, and was Formula 3 Champion in 1952, again in 1953, and in 1954 he only lost the title by a half-point. He took the title for a third time in 1959.

500cc Formula Three declined at an international level during the late 1950s, although it continued at a national level into the early 60s, being eclipsed by [[Formula Junior]] for 1000 or 1100 cc cars (on a sliding scale of weights).

A one-litre Formula Three category for four-cylinder carburetted cars, with heavily tuned production engines, was reintroduced in 1964 based on the Formula Junior rules and ran to 1970. These engines (a short-stroke unit based on the [[Ford Anglia]]<ref>Gauld, Graham, "Ford", in ''World of Automobiles'' (London: Orbis, 1974), Volume 6, p.696</ref> with a special 2-[[valve]] [[Cosworth]] or [[Holbay]] [[overhead valve|OHV]] down-draught [[cylinder head|head]], initially pioneered by Brian Hart, being by far the most efficient and popular) tended to rev very highly and were popularly known as "screamers"; F3 races tended to involve large packs of [[slipstream]]ing cars. The "screamer" years were dominated by [[Brabham]], [[Team Lotus|Lotus]] and [[Tecno (motorsport)|Tecno]], with [[March Engineering|March]] beginning in 1970. Early one-litre F3 chassis tended to descend from [[Formula Junior]] designs but quickly evolved.

For 1971 new regulations allowing 1600 cc engines with a restricted air intake were introduced. The 1971–73 seasons were contested with these cars, as [[aerodynamics]] started to become important.

Two-litre engine rules were introduced for 1974, still with restricted air intakes. {{As of
|2011|6
|alt=Today}} engine regulations remain basically unchanged in F3, a remarkable case of stability in racing regulations.

As the likes of Lotus and Brabham faded from F3 to concentrate on Formula One, F3 constructors of the 1970s included [[Alpine (automobile)|Alpine]], [[Lola Cars|Lola]], March, [[Modus Developments|Modus]], [[Group Racing Developments|GRD]], [[Ralt]], and [[Ensign (racing team)|Ensign]].

By the start of the 1980s however, Formula Three had evolved well beyond its humble beginnings to something closely resembling the modern formula. It was seen as the main training ground for future Formula One drivers, many of them bypassing Formula Two to go straight into Grand Prix racing. The chassis became increasingly sophisticated, mirroring the more senior formulae &ndash; [[ground effect in cars|ground effect]]s were briefly used in the early 1980s but were banned, in line with other FIA single-seater formulae; [[carbon fibre]] chassis started to be introduced from the mid-1980s.

Historically, March (up to 1981), Ralt (up to the early 1990s) and [[Reynard Motorsport|Reynard]] (1985–1992) had been the main chassis manufacturers in two-litre F3, with [[Martini (cars)|Martini]] fairly strong in France; Reynard pioneered use of [[carbon fibre]] in the mid-1980s replacing traditional [[aluminium]] or [[steel]] [[monocoque]] structures. [[Dallara]] however, after an unsuccessful Formula One project, focussed their attention on the formula in the early nineties and obliterated all the other marques with their F393. Within a couple of years, the chassis was considered a prerequisite to competitiveness, and today Dallara chassis are ubiquitous to the formula. In order to keep costs down, their chassis have had a three-year life-cycle, with only minor annual updates. It was agreed however to extend the life-cycle of the current F308 to four years to assist teams; this chassis however, has been replaced in 2012 with the new F312 chassis, intended to be run until 2017. Most F3 championships, most notably the [[British Formula 3|British]] series, offer a secondary class for cars from the previous life-cycle in order to provide a cheap point of entry for lesser funded teams and drivers.

==F3 cars==
Formula Three cars are [[monocoque]] [[chassis]], using [[slick tyre|slick]] racing [[Tyre (wheel)|tyres]] and [[wing]]s. Currently, [[Dallara]] manufactures the overwhelming majority of F3 cars, though [[Mygale]], [[Lola Cars|Lola]] (formerly in partnership with [[Dome (constructor)|Dome]] of Japan), [[ArtLine Racing|Arttech]], and SLC also have a limited output. In many smaller or amateur F3 racing series older cars are frequently seen. Usually these series are divided into two or more classes, to allow more participation.

[[Internal combustion engine|Engine]]s in FIA Formula 3 are all 3.4-[[litre]], 6-cylinder naturally aspirated [[specification|spec]] engines.<ref>{{Cite web|url=https://www.fiaformula3.com/About/Guide-To|title=Guide to Formula 3|website=FIAFormula3® - The Official F3® Website|language=en|access-date=2020-04-01|archive-date=2020-03-19|archive-url=https://web.archive.org/web/20200319165801/https://www.fiaformula3.com/About/Guide-To|url-status=dead}}</ref> 

Engines in other Formula 3 series must be built from a production model [[engine block|block]] (''stock block''), and often must be sealed by race or series organizers, so no private [[engine tuning|tuning]] can be carried out. [[Honda]] engines (prepared by [[Mugen Motorsports|Mugen]]) have perennially been popular, as have engines produced by [[Volkswagen]], [[Alfa Romeo in motorsport|Alfa Romeo]], or [[Renault]]. Currently the HWA-tuned [[Mercedes-Benz|Mercedes]] and the Volkswagen engines dominate the British and European series, with Mugen, [[TOM'S]]&ndash;[[Toyota]], [[Opel]], and [[Fiat]] being used by some teams.

Until the launch of the [[FIA Formula 3 Championship]] in 2019, there had never been a World Championship for Formula Three. In the 1970s and into the 1980s the European Formula Three Championship and [[British Formula 3 Championship]] (once one series had emerged from the competing British series in the 1970s) were the most prominent, with a number of future Formula One champions coming from them. France, Germany, and Italy also had important Formula Three series, but interest in these was originally subsidiary to national formulae &ndash; [[Formula Renault]] in France and [[Formula Super Vee]] in Germany. These nations eventually drifted towards Formula Three. The Italian series tended to attract older drivers who moved straight across from [[kart]]ing whereas in other nations drivers typically graduated to F3 after a couple of years in minor categories. The European series died out in the mid-1980s and the national series became correspondingly more important. For 2003, [[French Formula Three Championship|French]] and [[German Formula Three Championship|German F3]], both suffering from a lack of competitive entrants, merged to recreate the [[Formula 3 Euro Series]].<ref>{{Cite web |title=Formula 3 |url=https://www.fiaformula3.com/ |access-date=2023-06-12 |website=FIAFormula3® - The Official F3® Website |language=en}}</ref>

Brazil's [[Formula Three Sudamericana|SudAm Formula Three Championship]], which now has the most powerful engine of all Formula Three series, was known for producing excellent drivers who polished their skills in the British Formula 3 championship. Perhaps the most curious of all was the small [[All-Japan Formula Three Championship]].  Although few drivers spent a significant amount of time there, future stars such as [[Ralf Schumacher]] and [[Jacques Villeneuve]] scored victories there. An Asian series was established in 2001 and grew to produce past A1 drivers for Indonesia and Australia.

===Special races===
[[Image:Paucircuit.jpg|thumb|right|[[Átila Abreu]] driving for [[Mücke Motorsport]] during the 2005 [[Pau Grand Prix]] in France]]

In addition to the many national series, Formula Three is known for major non-championship races typically including entries from the national series, the best-known of which is the [[Macau Grand Prix|FIA Formula 3 World Cup]] (previously known as FIA Formula 3 Intercontinental Cup) at [[Macau]]. The first Formula Three Grand Prix of Macau was held in 1983 and won by [[Ayrton Senna]]. [[Michael Schumacher]], [[David Coulthard]], [[Ralf Schumacher]], and [[Takuma Sato]] have also won there. The Formula Three Grand Prix of Macau traditionally marks the end of the Formula Three season, with drivers from almost every national series participating.

Other major races include the [[Pau Grand Prix]] (from 1999 to 2006), the [[Masters of Formula 3]] (traditionally held at [[Circuit Park Zandvoort|Zandvoort]]), and the [[Korea Super Prix]] at [[Changwon]]. These events give fans in locations not visited by other major series a way to experience major international racing.

The [[Monaco Grand Prix Formula Three support race|Monaco F3 Grand Prix]] held until 1997 was also a famous special race. It was restored in [[2005 Monaco Grand Prix Formula Three|2005]] only, as a part of the F3 Euro Series.
