Formula 3 is the main feeder series for both F1 and F2. Like the F2 series, the FIA Formula 3 Championship is an exclusive F1 support series during Grand Prix weekends. As in every other feeder series, F3 cars are all the same, putting the focus on the driver and the knowledge of the teams. Max Verstappen is among the few drivers to have been promoted directly from F3 to F1.
