Honda has turned Aston Martin’s long-running power-unit wait into a firm post-summer deadline, with the Dutch Grand Prix now the target for its upgraded Formula 1 engine package.
Trackside general manager Shintaro Orihara confirmed at Silverstone that Honda is working towards introducing the new unit at Zandvoort, the first race after the August shutdown. The Race reported that the changes are internal, meaning Aston Martin should not need to redesign the AMR26 installation around the update.
Why Zandvoort now matters
The upgrade centres on combustion performance, friction reduction and reliability, with Honda also pointing to lubrication-system work as part of the package. RacingNews365 quoted Orihara saying the target is the Netherlands, ending the vaguer “summer” timeline previously attached to the programme.
For Aston Martin, that timing matters because the chassis side of the recovery plan is already being pulled forward around the final races before the break. Adrian Newey’s group is expected to deliver a heavily revised car, while Honda’s RA626H remains central to the wider 2026 rules reset, built around a 1.6-litre V6 and a 50:50 ICE-electric output balance described on Honda’s official technical page.
ReadMotorSport has already tracked how the ADUO engine review could shape 2026. This is the first sign of Honda converting that mechanism into a concrete race-weekend target.
