Honda to Debut New Power Unit at Aston Martin Filming Day Ahead of Dutch GP

Honda will introduce its new-spec Formula 1 power unit earlier than anticipated, running the updated engine in Aston Martin's AMR26 at a Hungaroring filming day this Wednesday. The Japanese manufacturer had initially targeted the Dutch Grand Prix for the debut, but the unit will now get an unofficial shakedown before the summer shutdown, giving the team extra mileage.

Why it matters:

The early debut offers Aston Martin a crucial head start as it attempts to build on the momentum from its B-spec car introduction in Hungary. With the Silverstone-based squad already showing improved pace and correlation, combining the new chassis with Honda's first permitted power unit upgrade of the season could significantly alter its midfield prospects. For Honda, it provides a low-pressure environment to validate reliability and performance before the race weekend.

The details:

• Filming day debut: The new power unit will run in the AMR26 for the first time during Wednesday's filming day at the Hungaroring, the same venue where the team just raced.
• Revised timeline: Honda had originally scheduled the power unit's introduction for the Dutch GP at Zandvoort on August 21-23, marking its first update of the year.
• Data gathering: Honda trackside general manager Shintaro Orihara confirmed the team has been supporting power unit integration in Hungary and collecting vital data to prepare for the next phase.
• B-spec progress: Aston Martin's updated car showed clear gains in Budapest, with Fernando Alonso reaching Q2 for the first time in 2026 and Lance Stroll finishing 13th, ahead of Cadillac, Williams, and Haas.
• Driver feedback: Alonso noted the correlation between simulation and track performance is strong, describing the B-spec as a "new baseline" while suggesting more setup optimization is still to come.

What's next:

All eyes will turn to Zandvoort, where Aston Martin will field the full package of B-spec chassis and Honda's new power unit in competitive conditions for the first time. Alonso has already flagged the Dutch GP as an "interesting check" on the team's true potential. If the correlation holds and the power unit delivers the expected gains, Aston Martin could emerge from the summer break as a genuine threat in the tightly contested midfield.
