Formula One has announced the start time of the 2021 season and the end of the race starting at 10 minutes per hour.
When Liberty Media dominated F1 in 2018, it shifted the race from the traditional 2:00 pm race start of European races, prioritizing later slots to increase American TV viewership. Liberty also decided to return the start to 10 minutes per hour so that broadcasters could better schedule pre-race shows.
10-minute delays were not common in F1 as pre-race ceremonies added in recent seasons, such as national anthems and pre-race anti-racism messages, further complicated the timing of pit lane opening. When can head to the grid.
In 2021, most European races will start at 3 pm. The Azerbaijan Grand Prix in Baku begins at 4 pm local time.
The two practice sessions on Friday will be reduced from 90 minutes to 60 minutes each. This is the same practice session that took place on Saturday before qualifying.
