Honda, the official power unit supplier for the Aston Martin F1 team, has revealed an important update about the ongoing work to iron out issues related to the power unit of its AMR26 F1 car that have been affecting the team’s performance, ahead of the upcoming Miami Grand Prix on May 3.

Since the beginning of the 2026 season, Aston Martin has been on the back foot due to vibrations in the power unit, leading to battery failures. Both drivers, Fernando Alonso and Lance Stroll, were afraid they would suffer from nerve damage due to extreme vibrations during race weekends.

Honda and Aston Martin have acknowledged that the issue cannot be resolved by addressing the power unit alone, given its relationship with the chassis and other components. The team has been nowhere near as competitive as its rival teams. Aston Martin is currently placed last in the Constructors’ Championship with zero points scored in the first three races.

Honda set to work around the clock during the month-long break as a result of the cancellations of the Bahrain and Saudi Arabian Grands Prix, due to the Iran war. Despite the additional time made available, Honda is seeking more time to resolve the power unit issues.
