Spanish media report huge Honda deficit as Aston Martin targets 2027 F1. Spanish media report a major performance crisis for Honda’s F1 power unit.

Inside the Aston Martin-Honda crisis

Among Ferrari fans – who have now been waiting since 2008 to win a World Championship title – the phrase “next year we will win” has become an ironic and bittersweet mantra. But this time, that idea applies even more to the green cars of the Aston Martin team. The Silverstone-based squad, in partnership with Honda, was expected to be one of the major protagonists of this season. Instead, the start of the new regulatory cycle has been a complete disaster for the Lawrence Stroll-owned team. The AMR26 is suffering from a wide range of issues, but it is clear that a significant part of the performance deficit also comes from the Japanese power unit, which is both unreliable and significantly less competitive than its rivals.

During this period away from on-track action, attention has shifted to the impact that ADUO – the FIA regulatory mechanism designed to give manufacturers lagging behind a chance to recover – could have on the rest of the season. According to Spanish newspaper Marca, which closely follows Aston Martin due to the presence of Fernando Alonso in the team, the gap between Honda’s power unit and Mercedes – currently the benchmark across the grid at the start of the season – is estimated at around 5%. To understand the scale of this deficit, it is worth noting that the ADUO framework originally defined performance gaps of 2% and 4% as thresholds for additional development support.

With the cancellation of the Bahrain and Saudi Arabian races, the first power unit upgrades are now expected to be introduced at the Monaco Grand Prix, the sixth round of the championship. However, according to Spanish media reports, Honda’s upgraded engine – developed thanks to ADUO concessions – is more likely to arrive at Aston Martin’s home race in Silverstone. Given the enormous performance gap that Honda currently faces compared to its competitors, it is difficult to imagine that even meaningful improvements would be enough to dramatically transform the British team’s competitiveness.

As already suggested by Aston Martin team principal Adrian Newey during the first press conference of the year in Australia, it is not excluded that most of the team’s resources and development efforts will already be redirected towards 2027, rather than being “wasted” on a project that can only be patched up with limited chances of delivering significant results. The objective may therefore be to completely redesign the power unit, with the hope of starting the next championship much closer to the rest of the grid.

In summary, the reports regarding Honda’s 5% deficit to Mercedes paint a grim picture for Aston Martin’s 2026 campaign. While the ADUO system offers a path for recovery, the sheer size of the gap suggests that a mid-season miracle is unlikely. With a technical mastermind like Adrian Newey at the helm, the decision to pivot early toward 2027 seems like a pragmatic, if painful, admission of the current project’s limitations. For Fernando Alonso and the team, the remainder of the 2026 season may serve as an extended laboratory session, prioritizing long-term stability over immediate points. As the grid prepares for the European leg of the season, the focus will be on Silverstone to see if the “Silverstone spec” engine can at least provide a foundation for the future.
