Honda is set to introduce its updated Formula 1® power unit during an Aston Martin filming day at the Hungaroring, scheduled for the Wednesday following the Hungarian Grand Prix. This move comes ahead of the official race debut planned for the Dutch Grand Prix at Zandvoort later in August 2026.
The new power unit update represents the first development allowed under the Additional Development Upgrade Opportunity (ADUO) regulation. Honda will run the upgraded engine in the Aston Martin AMR26 during the filming day, providing the team with valuable data and integration experience before the race weekend. Both Aston Martin drivers, Fernando Alonso and Lance Stroll, are involved in this process.
This development follows a promising Hungarian Grand Prix for Aston Martin, where the team introduced a B-spec version of the AMR26. The upgrade showed clear improvements in both qualifying and race pace, with Alonso reaching Q2 for the first time this season and Stroll finishing 13th. Alonso described the Hungarian performance as a positive step forward and expressed cautious optimism about the upcoming engine update at Zandvoort.
Honda’s involvement has extended beyond the power unit itself, as the manufacturer has been supporting Aston Martin with power unit integration and data collection during the Hungarian Grand Prix. This collaboration aims to ensure a smooth transition to the updated engine package and to maximize its potential benefits on track.
The filming day at the Hungaroring will take place before the summer shutdown, allowing Aston Martin and Honda to gather important insights without impacting race weekend preparations. While specific technical details and expected performance gains from the update have not been disclosed, the step aligns with the team’s ongoing efforts to enhance competitiveness during the 2026 season.
Fernando Alonso’s positive remarks about the recent progress highlight the cautious but hopeful approach within the team. The Dutch Grand Prix will mark the first official race appearance of the new Honda power unit, providing a clearer indication of its impact under competitive conditions.
This update forms part of the broader development landscape in Formula 1®, where teams and manufacturers continuously seek incremental improvements within regulatory frameworks. Aston Martin’s recent progress and Honda’s power unit upgrade reflect this ongoing pursuit of performance gains as the championship progresses through the summer period.
