Yuki Tsunoda topped his fifth Free Practice session of the season to get his weekend off to the perfect start in Sakhir, beating out teammate Jehan Daruvala by 0.2s.
Luca Ghiotto was a further tenth back in third place, as title rivals Mick Schumacher and Callum Ilott finished in seventh and 18th.
Christian Lundgaard led the field out onto the track for the final Free Practice session of the season, but it was Championship leader Schumacher who set the first flying lap, touring around the outer layout of the Bahrain International circuit in 1:04.094.
The German wasn’t at the top of the order for long, as Round 11 Feature Race winner Felipe Drugovich dropped the quickest time down to 1:03.780 before Robert Shwartzman and Théo Pourchaire dived into second and third.
Tsunoda briefly usurped the MP Motorsport man but Drugovich battled back and returned his name to the summit. Tsunoda had another go on his next tour and this time made it stick, taking P1 with 1:03.780. The Japanese driver’s Carlin teammate Daruvala popped up in second behind him, as Drugovich dropped to fourth below Ghiotto.
Attention switched to longer runs and data gathering, before Artem Markelov’s BWT HWA RACELAB went up in smoke down the main straight. This brought out a red flag with four minutes of the session to go and the decision was taken not to restart.
That meant that Tsunoda retained his place in P1, ahead of teammate Daruvala. Ghiotto finished third and Drugovich took fourth, ahead of Nikita Mazepin, Marcus Armstrong, Schumacher and Guanyu Zhou. Louis Delétraz finished ninth, ahead of Shwartzman. Meanwhile, Schumacher’s main title rival Ilott struggled to P18 in the opening session of the weekend.
The title fight will pick up in Qualifying at 6.45pm (local time) and Ilott will need to be back on the pace to keep his hopes to sealing the crown alive.
