Follow this page for updates during the day of all the news and developments from the first of three days of testing in Bahrain.
All ten teams are present for what is expected to be a busy three days and the only chance to test the cars with Pirelli’s new tyres ahead of the first race in two weeks’ time.
A sandstorm during the lunch break made track conditions incredibly dusty at the start of the afternoon session. Teams continued with testing regardless despite the slippery conditions and limited visibility.
Mercedes recorded just one lap in the first three hours and 20 minutes of the session after a gearshift issue forced the team to replace the car’s gearbox. The broken transmission will now be analysed to understand the cause of the problem.
World champion Lewis Hamilton took over driving duties at Mercedes in the afternoon, but had his initial running limited after asking for a change of pedals. He then reported a loose rear-view mirror and returned to the pits.
Charles Leclerc caused the only red flag of the morning session when his Ferrari stopped on track at Turn 4 with ten minutes remaining in the morning session.
Haas also made a gearbox change following a hydraulic issue, limiting Mick Schumacher’s mileage on his debut with the team in the morning.
Max Verstappen spun in his Red Bull at Turn 2 early in the session but escaped any damage.
