Editing Formula Three (section)

==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.
