After missing the official five-day shakedown in Barcelona, Williams completed the most laps across the first of two three-day tests in Bahrain.
The Grove-based team managed 415 laps of the Bahrain International Circuit after a long period of smooth running, topping the lap count by the finest of margins.
McLaren was second on the laps-completed chart, managing 414 laps between reigning world champion Lando Norris and Oscar Piastri.
With 408 laps, Ferrari was the only other team to surpass 400 laps, marking yet further significant mileage for the Scuderia following on from Barcelona.
Interestingly, after managing the most laps in Barcelona, Mercedes completed the second-fewest laps, clocking just 270 laps of the track.
The only team with fewer laps completed than the Silver Arrows this week was Aston Martin, which only just broke the 200-lap barrier by three.
It marked the latest setback for Aston Martin and Honda, who are quickly falling behind their competition when it comes to gathering data.
