• A seven-round provisional calendar was revealed on 1 December 2020.^[25] It represents a return to normalcy after the Coronavirus pandemic forced change in the 2020 season. The only addition on the original from 2020 is the Algarve International Circuit, which had lost its spot in the provisional calendar in 2020 due to scheduling conflicts. Due to the track's late addition to the Formula 1 calendar however, it was forced to be removed from the schedule in 2021 as well and was replaced with the Autodromo Internazionale Enzo e Dino Ferrari.^[26] Multiple other tracks had date changes because the pandemic caused the series to start in August rather than the planned April.

This section needs to be updated. Please help update this article to reflect recent events or newly available information. (February 2022)

Points are awarded to the top 10 (Pro) or top 6 (Am, Pro-Am, Teams) classified finishers. If less than 6 participants start the race or if less than 75% of the original race distance is completed, half points are awarded. At the end of the season, the lowest race score is dropped; however, the dropped race cannot be the result of a disqualification or race ban.
