F1 pre-season testing: Driver line-ups for Bahrain

After a busy winter, Formula 1 teams will put themselves in gear on Friday at the Bahrain International Circuit as the 5.412-kilomtere Sakhir track hosts three days of pre-season testing

The action starts at 10am local time (7am GMT) running for four hours before a one hour break, and then continuing to 7pm (4pm GMT) each day. The final hour is due to take place with the floodlights on to replicate the conditions of the Bahrain Grand Prix night race.

Some teams have opted to divide the day between their drivers, while others have allocated a full day of running before splitting duties on Day 3.

Among F1's ten teams, Williams is the only outfit that has assigned track time to its test driver, or Roy Nissany, over the course of the three sessions.

Finally, only three teams - Mercedes, Alfa Romeo and Williams - head into the 2021 season with an unchanged driver line-up, which only underscores for the remaining seven outfits the importance of enjoying a trouble-free three days of mileage in Bahrain ahead of F1's opening round at Sakhir on March 28.
