F1 LIVE | First day of winter testing in Bahrain - all the action from Day 1

With the Barcelona tests now in the books — where Ferrari, courtesy of Lewis Hamilton, topped the timesheets while Mercedes stole the spotlight on mileage — everything is set for the first official winter pre-season test, where teams are expected to start turning up the intensity.

On Monday, the final three teams yet to unveil their liveries — Aston Martin, Cadillac and McLaren — revealed the colour schemes they will race with this season, officially bringing the launch calendar to a close.

Attention now shifts to the track, with all eleven teams set to run on Day 1 of the three-day test. Unlike Barcelona, the Bahrain running will feature partial TV coverage, with the final hour broadcast live each day, while live timing will be available throughout the full eight-hour session.

Almost all teams have already confirmed their driver line-ups for the day, with some opting to run a single driver throughout the entire session, while others will split duties between their two racers — as is the case with McLaren and Mercedes.

From February 11 to 13, each day of testing is split into two four-hour sessions — one in the morning and one in the afternoon — separated by a one-hour lunch break. Teams can choose to rotate drivers between the two runs or keep a single driver in the car for the entire day.
