Which teams completed the most laps on the final day of testing in Bahrain?

Alfa Romeo put in the most miles of any team on the final day of testing in Bahrain, despite causing a late red flag stoppage due to a technical issue.

Guanyu Zhou and Valtteri Bottas put in 150 laps of the circuit across the day, with Bottas breaking down with an apparent gearbox issue on the 151st tour.

Bottas had just set the fourth-fastest time of the day, set on the C3 Medium tyre, when he broke down on track.

Behind Alfa Romeo, Mercedes did 149 laps between George Russell and Lewis Hamilton, with AlphaTauri in third place and adding to their impressive tallies from the first two days.

Williams were next on the list after completing 142 laps and making up for their loss of running on Friday, after a small fire on Nicholas Latifi's car.

McLaren were the team with the fewest laps, although it was still a much better day for the Woking-based outfit as Lando Norris managed 90 laps – one-and-a-half Grand Prix distances as he attempted to recover lost time from the first two days due to brake issues.

Latifi does the miles for Williams

In terms of the individual lap charts, Latifi put in the hard work for Williams on Saturday after the aforementioned fire-related delays.

While both he and Alex Albon had a stint at the wheel, Latifi did 124 laps in contrast to Albon's 12 – the lowest of all for the final day.

Fernando Alonso, driving the full day for Alpine, was up next with 122 laps, while Pierre Gasly managed 91 for AlphaTauri in the morning.

Norris was another strong performer, logging 90 laps on a much better day for McLaren.

Those with the lowest lap counts, along with Albon, were Red Bull's Sergio Perez as he bedded in the team's upgrades during the morning session, as well as Haas' Kevin Magnussen after a couple of leaks on the VF-22.
