The GB3 Championship is a single seater motorsport series based in the United Kingdom. The championship is the UK's premier single-seater category, and is aimed at young racing drivers moving up from FIA Formula 4 championships or Karting. Having previously been known since 2013 as the BRDC Formula 4 Championship, the championship was renamed the BRDC British Formula 3 Championship with the backing of the FIA in March 2016. The championship was rebranded to GB3 Championship in August 2021. History On 23 March 2016, the FIA and MSA revealed to the FIA World Motor Sport Council that an agreement had been reached the day prior to rebrand the BRDC Formula 4 Championship in order to reflect the increased pace of the new car designed for the 2016 season, and to fill the void left after the British Formula 3 Championship folded in 2014. The series will co-headline seven of eight rounds with the British GT Championship. The BRDC British Formula Three Championship notably does not use a FIA Formula 3 car, instead using a car based on the Formula 4 specification that is elevated to the pace of F3 cars. The car is designed by Italian manufacturer Tatuus to the F3 safety regulations including side impact panels, front and rear carbon impact structures, wheel tethers and extractable seat. British engine and electronics manufacturer Cosworth provides the engine and related control electronics for the FA-016. The car also uses a unique Sadev limited slip differential. The cars are around the same pace as the previous FIA F3 specification car used prior to the series folding in 2014. The FIA have previously been stringent with assigning of national F3 status. The Euroformula Open Championship had to drop the F3 moniker due to it using an old specification Dallara F312 Formula 3 car and low specification engine that did not meet the standards set by the FIA's single-seater commission. The granting of the national F3 status to the Tatuus-Cosworth highlights the pace of the car in relation to the FIA's other formula specifications. BRDC British F3 morphed out of the BRDC F4 category, which ran for three seasons before the new car was introduced. The F4 name was operated by the 750 Motor Club before being awarded to MotorSport Vision. Under the BRDC F4 moniker, British driver Jake Hughes was the first champion of the series in 2013, driving for Lanan Racing. The
