Bahrain GP FP3: Antonelli Fastest as Mercedes Ease Update Worries

Mercedes had spent Friday quietly sweating over whether their latest update actually did anything useful. Kimi Antonelli spent FP3 answering that question in the only way that matters: by going fastest, comfortably, on a track that had given nobody else much to smile about.

The championship leader set a 1:36.302 in the final practice session before qualifying for the Bahrain Grand Prix in Malaysia, 0.278 seconds clear of Max Verstappen and more than half a second ahead of Isack Hadjar in third. It was the kind of lap that quietens a garage rather than one that merely tops a timesheet, not because Antonelli needed reminding he can be quick, but because Mercedes needed reminding their car could be too.

Russell Six Tenths Adrift, and That Matters

What makes Antonelli's effort more than a flattering headline is where it left his own teammate. George Russell ended up fourth, six tenths off Antonelli's best. If the Mercedes package genuinely transformed the W17, you would expect both cars to be near the top of the order within shouting distance of each other.

He has now won two of the last five races, and a 0.278s margin over a Red Bull that looked genuinely rapid in Baku is not a man cruising through a title lead.

Verstappen's Quiet Threat

Credit where it is due: Verstappen was fastest in FP1, but had not managed a soft-tyre run during Friday afternoon; yet he turned up in FP3 and slotted himself directly behind Antonelli. Red Bull's recent form, built on a strong Baku weekend, now looks like it travels. Isack Hadjar backed that up in third, continuing what has become a genuinely impressive run of form for the sister car, even if he admitted over team radio that the rear end was proving unpredictable through Turns 1 and 9.

"The car is totally unpredictable in Turn 9 and Turn 1. You never know when the rear is going to break away." - Isack Hadjar

Hadjar's complaint did not stop him splitting the two Mercedes.

Ferrari and McLaren, Present but Unconvincing

Charles Leclerc and Lewis Hamilton filled fifth and sixth for Ferrari, with Leclerc notably choosing to start the session on hard tyres rather than keep two fresh sets of hards for Sunday's 56-lap race. It was a deliberate bit of tyre husbandry on a track that chews through rubber, and it still yielded the fastest early time of the session by almost half a second. Hamilton had his own gripe, feeling impeded by Arvid Lindblad's Racing Bulls through the opening corners, and he never looked entirely comfortable on his soft tyres.

Lando Norris and Oscar Piastri rounded out the top eight for McLaren, both choosing mediums to begin their running, and both ending up more than half a second off Antonelli's benchmark. For a team that won the previous two races before this run of Mercedes dominance the gap to the pace-setter is a concern.

A Session That Took Its Time

FP3 did not exactly burst into life. With Sepang back on the calendar after a long absence, only Franco Colapinto and Sergio Pérez bothered with early running, whilst Liam Lawson completed an install lap and promptly retreated to the garage. The track stayed largely empty for the first quarter of an hour, partly because nobody wanted to burn through medium or hard sets better saved for race day in the heat.

Oliver Bearman triggered a red flag with 35 minutes to go, after a strip of carbon broke free from his front-right brake duct and had to be retrieved by a marshal from the inside of Turn 10. The stoppage lasted five minutes before running resumed, and the headline order changed significantly once it did, with Mercedes and Verstappen only going out after the restart.
