Alonso delivers blunt verdict on F1 power units after FIA regulation shift

Earlier, the FIA, Formula 1 and engine manufacturers agreed on a series of updates to the current regulations. The revisions are designed to improve energy management and fuel flow characteristics, while also making qualifying more push-focused without diluting the closer racing expected from the new ruleset.

Under the new framework, the power split will be set at 53/47 between the internal combustion engine (ICE) and the battery for 2026. That balance will now shift more towards the ICE, moving to 58/42 initially, before increasing further to 60/40 for the 2028 season.

When quizzed about the changes implemented, Alonso, who was measured in his assessment, suggested it will take time to properly judge the impact of the changes while hinting that deeper structural issues may already be baked into the concept. Speaking to the media in Barcelona, Alonso said:

Alonso is among several drivers, including Max Verstappen and Lando Norris, who have voiced concerns about the current regulations, with the latest FIA adjustments seen as an attempt to soften some of the underlying weaknesses in the hybrid formula.

The Barcelona Grand Prix proved to be a difficult outing for the Spaniard, who was forced to retire on lap 40. Going into the weekend, Alonso had set a reflective tone, saying: “It's going to be a special weekend, probably my last Barcelona race in Formula 1, so I want to say thanks to everyone.”

But the reality on track was far less celebratory. Struggling for pace throughout, he endured a tough start to the weekend with Aston Martin F1 Team, and for the first time since the 2024 British Grand Prix, he was outqualified by teammate Lance Stroll, ending up at the back in P22.

His race was further compromised after Aston Martin opted for a pit lane start following changes to his energy store and MGU-K. Then, on lap 40, his AMR26 came to a halt at Turn 9. Alonso later explained the issue, pointing to a battery-related failure. Despite the disappointment, the 44-year-old still made a point of thanking the fans who supported him throughout a challenging home weekend.
