Calan Williams (born 30 June 2000) is an Australian racing driver who is competing in the GT World Challenge Europe Endurance Cup with BMW M Team WRT.

[10] A triple of victories followed in the final round to end the season, which meant that Williams had finished second in the standings, missing out on the title by just eight points to Sam Dicker.

In October 2019, it was announced Williams had signed with Jenzer Motorsport for the 2020 season of the FIA Formula 3 Championship, which he stated was "a huge opportunity".

[33] In the following two rounds Williams would be unable to score points, and at the Circuit de Spa-Francorchamps he was involved in a collision with Amaury Cordeel in the Eau Rouge-Radillion complex.

[40] At the following round in Saudi Arabia, Williams managed to qualify in seventh place, giving him the opportunity to start the sprint race from the second row.

[41] A pair of anonymous races at Imola came up next,[42] whereas the round at Barcelona would harbour initial promise, as the Australian qualified tenth, setting him up to start from pole position on Saturday.

[46] In October, Williams and Trident parted ways before the season finale in Yas Marina, citing the need to "focus on the next steps of his motorsport career".

[49][50] The season began promisingly, as the Australian took a podium in his category during the opening Endurance Cup round at Monza, finishing third along with Niklas Krütten and Jean-Baptiste Simmenauer.

[51] During his maiden weekend in the Sprint Cup, Williams managed to take a class victory in race 2 at Brands Hatch, having inherited the car from teammate Krütten in a leading position.

[52][53] At Le Castellet, the Australian was able to progress from fourth to second in class during the opening stint, though the team was forced to retire when Simmenauer stopped the #30 with a suspected engine issue after two hours.

[58] The round at Valencia turned out to be a setback in the #30's Gold Cup title ambitions, as contact at the start of race one forced them to retire early.

[60] Williams, who started the car, got into the lead as a rain shower caused the leading WRT of Maxime Martin to slide off, before Krütten was passed shortly after a safety car restart, finishing third overall and winning the class race, thus bringing home both the Sprint Cup title as well as the overall Gold Cup championship.

[66][67][68] Despite missing the podium in race 1 at Magny-Cours Williams remained first in the Silver Cup standings going into the final round, one for which he would be joined by Sean Gelael.

[69] With a podium in the final race Williams and the #30 WRT squad were crowned Silver Cup champions, five points ahead of the #10 Boutsen VDS outfit of Aurélien Panis and César Gazeau.

[72] To amass the funding needed for a racing career in Europe, Williams and his father set up an incorporated company, which investors would be able to buy shares in.
