FIA Formula 3 Championship · Supporting the Formula 1 calendar, International
The FIA Formula 3 Championship (FIA F3) is a third-tier international single-seater racing championship organised by the Fédération Internationale de l'Automobile (FIA). The championship launched in 2019 as a feeder series for the FIA Formula 1 World Championship and FIA Formula 2 Championships. It was the result of a merger between two third-tier single-seater racing championships, the GP3 Series and the FIA Formula 3 European Championship. This championship is part of the FIA Global Pathway consolidation project plan. Unlike its co-predecessor, the Formula 3 European Championship, the series runs exclusively in support of Formula One races.
Typical window: March to September, alongside Formula 1. Organisers publish the following year's date at different points in the season — the official site above is the authority. This page is rebuilt on every deploy, so a confirmed date appears here as soon as it is public.
