Williamswas the most active team on track during the opening morning of the Bahrain test.
Williams were expected to deliver some answers after skipping the behind-closed-doors Barcelona test, and at least on the reliability front, those answers have come through.
The Williams driver, at the wheel of the FW48 in what was effectively the Grove-based team’s first official on-track session, racked up an impressive 77 laps — covering almost one and a half race distances. It was then Alex Albon's turn in the afternoon, and the team set a total of 145 laps.
Max Verstappen completed the most laps today, as he participated in both the morning and the afternoon session as well. The Dutchman put up a total of 136 laps in Sakhir.
A data anomaly meant that Aston Martin could only do 36 laps today with Lance Stroll behind the wheel.
