As previously announced, from 2021, each F3 event will comprise three races instead of two, which means that the weekend format had to be revised. 

Weekend format 

There will be no changes on Friday, with one Free Practice session of 45 minutes and one Qualifying session of 30 minutes. 

Two races will take place on Saturday (Race 1 and Race 2) whilst Race 3 will occur on Sunday morning ahead of the Formula 1 Grand Prix. All three races will be forty minutes long. 

A timetable will be issued before every round to determine the timing of each session. 

Starting grids 

With three races and only one Qualifying session over the weekend, it has been decided that the final classification of Friday’s Qualifying session will determine the starting grid for Sunday’s Race 3. 

The starting grid of Saturday’s Race 1 will be determined by reversing the top 12 finishers of Friday’s Qualifying session. 

Finally, the starting grid of Race 2 will be determined by reversing the top 12 finishers of Saturday’s Race 1. 

Points attribution 

As it is currently the case, the driver who takes pole position following the final classification of Friday’s Qualifying session will be awarded 4 points. 

Since the Race 1 and Race 2 starting grids are determined by reversing part of earlier classifications, it has been decided that there will be fewer points on offer in both events for the Top 10 finishers (15, 12, 10, 8, 6, 5, 4, 3, 2, 1).

The Top 10 classified drivers of Race 3 will then be awarded more points (25, 18, 15, 12, 10, 8, 6, 4, 2, 1). 
2 points will be awarded to the driver who sets the fastest lap in each race. Any driver who is not classified in the top ten positions at the end of the race will not be eligible for fastest lap points. 

The maximum number of points that a driver can score over a race weekend has been increased from 48 to 65. 

Tyre allocation 

From 2021, each driver will have five sets of dry-weather tyres (one more than previously) and two sets of wet-weather tyres available at each event. 

FIA Formula 3 CEO Bruno Michel said: “I am pleased to reveal the changes to our sporting regulations which have been approved by the World Motor Sport Council. 
“Race 3 will take place on Sunday which is the day of the Formula 1 Grand Prix. As its starting grid will be determined by the final classification of Qualifying, we decided as in the past to award more points to the Top 10 finishers. 
“Having two reverse grids on Saturday will really spice up the championship and I am sure it will increase even further the entertainment on track. On top of that, it will give more drivers the opportunity to display their talent in front of the Formula 1 community.”
