Formula 1's 2025 season kicks off with three days of testing in Bahrain - but who is driving when?
These three days are the only time all 10 teams will share a track before the 24-race campaign gets under way in Australia on March 16.
With so many drivers switching places and a bumper crop of rookies, there will be plenty to watch across the three days.
Each team can only run one car so drivers have to split driving duties across the three days.
Below you'll find a list of a team by team list of what's planned, with the full driver line-up for the day's session at the bottom of the page.
McLaren
Wednesday: Piastri (AM), Norris (PM)
Thursday: Piastri (AM), Norris (PM)
Friday: Norris (AM), Piastri (PM)
McLaren was first to run a 2025 F1 car with a shakedown at Silverstone in a temporary livery almost two weeks before pre-season testing began.
The reigning constructors' champion is giving Oscar Piastri the first morning in Bahrain before Lando Norris takes over in the afternoon, a pattern that repeats on Thursday then inverts on Friday.
Ferrari
Wednesday: Hamilton (AM), Leclerc (PM)
Thursday: Hamilton (AM), Leclerc (PM)
Friday: Leclerc (AM), Hamilton (PM)
Lewis Hamilton will start Ferrari's test behind the wheel of the SF-25 before handing over to Charles Leclerc for the second half of Wednesday - a plan it repeats on Thursday.
Charles Leclerc will kick off the final day of running at the wheel before Hamilton ends Ferrari's test on.
Red Bull
Wednesday: Lawson (AM), Verstappen (PM)
Thursday: Lawson
Friday: Verstappen
Liam Lawson will kick off Red Bull's pre-season test before handing over to Max Verstappen for the post-break running.
Lawson will occupy the RB21 for the Thursday while Verstappen will do all the driving on Friday.
Mercedes
Wednesday: Antonelli (AM), Russell (PM)
Thursday: Russell (AM), Antonelli (PM)
Friday: Antonelli (AM), Russell (PM)
Mercedes rookie Kimi Antonelli will kick off the team's test running on Wednesday morning before handing over to George Russell in the afternoon.
Russell will remain in the car for the first half of Thursday before handing back to Antonelli who will continue into Friday morning before Russell rounds off the test.
The Mercedes W16 will have completed its first shakedown in Bahrain on Tuesday, one day prior to the test.
Aston Martin
Wednesday: Alonso (AM), Stroll (PM)
Thursday: Alonso (AM), Stroll (PM)
Friday: Alonso (AM), Stroll (PM)
Fernando Alonso will be behind the wheel of the AMR25 before handing the car over to Lance Stroll for the second half on the first two days.
The initial plan was for the roles to swap on Friday, but Alonso was back in the car for the morning session due to Stroll being unwell. Stroll will return for the second session.
Alpine
Wednesday: Doohan (AM), Gasly (PM)
Thursday: Gasly (AM), Doohan (PM)
Friday: Doohan (AM), Gasly (PM)
Alpine rookie Jack Doohan will be behind the wheel of the new A525 first in Bahrain before handing over to Pierre Gasly ahead of his third season with the team.
They'll continue to share driving duties across Thursday and Friday with Gasly finishing the test.
Haas
Wednesday: Bearman (AM), Ocon (PM)
Thursday: Ocon (AM), Bearman (PM)
Friday: Bearman (AM), Ocon (PM)
Haas's all-new 2025 driver line-up will evenly split the running in the new VF-25 across the three days.
Ollie Bearman, who has already raced for Haas twice in 2024 as a stand-in, will kick off Haas's test on Wednesday morning with Ocon concluding running on Friday.
Ocon completed all of the running during the VF-25's shakedown at Silverstone on February 16.
Racing Bulls
Wednesday: Tsunoda (AM), Hadjar (PM)
Thursday: Tsunoda (AM), Hadjar (PM)
Friday: Hadjar (AM), Tsunoda (PM)
Red Bull's second team has already given its VCARB 02 a shakedown run at Imola a week ahead of testing.

Williams
Wednesday: Albon (AM), Sainz (PM)
Thursday: Sainz
Friday: Albon
Alex Albon and Carlos Sainz will share driving duties on day one of the test for Williams before Sainz completes all of the running on Thursday and Albon has the car all to himself on Friday.
Sauber
Wednesday: Hulkenberg (AM), Bortoleto (PM)
Thursday: Hulkenberg (AM), Bortoleto (PM)
Friday: Bortoleto (AM), Hulkenberg (PM)
The team's last year before becoming a full Audi works team kicks off with new signing Nico Hulkenberg behind the wheel on Wednesday, before rookie Gabriel Bortoleto jumps in for the afternoon.
Prior to the Tuesday before testing the car hadn't run on track, so this line-up has had among the least amount of track time compared to many of its rivals.
