A Friday loaded with technical warnings and reliability concerns ends with the Australian on top, Pérez stranded in the garage, Colapinto under investigation and Aston Martin running on its last batteries.

Formula 1’s first FP2 of the 2026 season delivered its most revealing session yet on Friday afternoon at Albert Park. Where Ferrari had controlled FP1, the second practice session of the Australian Grand Prix told a different story: Oscar Piastri clocked a 1:19.729 to top the timesheets, becoming the only driver to break the 1:20 barrier all day, and repositioned McLaren as the clearest reference point heading into the weekend. It was not, however, a clean session. Far from it. It was an hour of incidents, mechanical failures and strategic choices that raised more questions than it answered about the true pecking order.

Kimi Antonelli and George Russell completed the provisional podium for Mercedes, a team that had kept its cards close in FP1 and emerged with genuine pace in FP2’s qualifying simulation. Lewis Hamilton finished fourth, just 0.176 seconds off his former team. Mercedes looked composed on both qualifying pace and long-run management, no small feat given that the 2026 power unit demands an almost equal split between the internal combustion engine and the electrical deployment system (MGU-K), a proportion not seen since the V8 era ended in 2013.

Max Verstappen ended the session sixth, more than six tenths off Piastri’s benchmark, after a session interrupted by his own incidents: the four-time champion went off spectacularly at Turns 9-10, sending the RB21 through the gravel trap before continuing at full throttle. The excursion proved harmless to his physical safety, but the car returned to the garage for a new floor (the aerodynamic panel that lines the underside of the chassis and is central to generating downforce through ground effect). Lando Norris, who had managed only seven laps in FP1 due to a gearbox failure, finished seventh in FP2, still a full second behind his team-mate. Questions over McLaren’s competitiveness in this new era have not been fully silenced.

Friday afternoon produced two contrasting Latin American narratives. Franco Colapinto finished 18th and was placed under investigation by the stewards after being noted for travelling unnecessarily slowly on the racing line along the main straight. Alpine confirmed that Colapinto was experiencing a technical issue with his car at that moment, which would explain the reduced speed, but the post-session investigation remained open. Through the course of the FP2, the Argentine set a best lap of 1:23.199 on the soft compound (Pirelli’s C5, the softest tyre available in Melbourne this weekend), leaving him nearly four seconds off the pace leader.

For Sergio Pérez, his long-awaited return to Formula 1 with Cadillac began as badly as possible. The Mexican, back after a year away from the grid in 2025, completed just two laps before a technical failure forced him to stop at Turn 11, triggering a Virtual Safety Car (a caution period that slows the field to allow marshals to attend an on-track incident without stopping the session outright). Cadillac confirmed a sensor fault on the car as the cause of the premature retirement. In total, Pérez accumulated just 16 laps across both Friday sessions, a figure that significantly limits the team’s ability to gather setup data on a circuit as demanding as Albert Park.

The biggest story of the day, however, belongs to a team, not a driver. Aston Martin endured the worst Friday in the paddock, and Adrian Newey, the team’s headline signing, delivered alarming news after the sessions: the squad is currently without spare batteries for its Honda power units. Only the two packs already installed in the Alonso and Stroll cars remain operational. Excessive vibrations generated by the new power unit, a problem that has persisted since pre-season testing in Bahrain, have destroyed the spare components.

“We’ve had a fresh problem with the communication between the battery and its management system. But the much more underlying problem is the vibration issues that we continue to struggle with,” Newey said, adding that the team has “only two batteries left, the two that are in the car.” Alonso did not run in FP1 and accumulated only 15 laps total on the day. Stroll’s times, more than five seconds off the pace on soft tyres, hovered uncomfortably close to the 107% threshold that can deny a car entry to qualifying.

The day also produced a pit lane incident: George Russell clipped the Racing Bulls of Arvid Lindblad while exiting his garage, damaging the Mercedes front wing. The stewards announced a post-session review over right-of-way in the fast lane.

Friday closed with McLaren and Mercedes as the two clearest benchmarks ahead of Saturday, Ferrari more subdued than its FP1 form had promised, and Red Bull carrying questions about balance (the distribution of mechanical grip between the front and rear axles across all corners). With the new technical regulations turning energy management into a decisive variable on a lap-by-lap basis, Australia is shaping up to be the first true examination of who has understood the new era of Formula 1 best.​​​​​​​​​​​​​​​​
