Honda Admits Years Away from F1 Led to Current Struggles with Aston Martin

Honda’s official return to Formula 1 as Aston Martin’s works power unit supplier has been derailed by severe reliability issues, with the Japanese manufacturer openly blaming its own prolonged absence from the sport for the team’s disastrous start to the 2026 season. At its home race in Suzuka, Honda conceded that rebuilding its F1 organization after stepping back has proven a critical weakness, leaving the team fighting vibrations and race-ending failures instead of competing for points.

Why it matters:

This is a stark admission from a manufacturer with a championship-winning pedigree, highlighting how quickly technical and organizational momentum can be lost in F1’s hyper-competitive environment. For Aston Martin, a team with ambitious title aspirations backed by significant investment, a fundamentally flawed power unit jeopardizes its entire multi-year project and partnership, turning a promised resurgence into a public crisis of performance and confidence.

The details:

• Honda Racing Corporation president Koji Watanabe pinpointed two main reasons for the struggle: the challenging new 2026 power unit regulations and, more critically, the organizational gap created by its exit.
• Honda officially stopped its F1 activities at the end of 2021 and announced its return with Aston Martin in 2023. Watanabe admitted that during this period, “our Formula 1 activity was quite limited” and it “took a bit of time to rebuild the organization.”
• This admission is notable because Honda never fully left the paddock; it maintained a technical partnership with Red Bull Powertrains from 2022-2025, manufacturing and servicing the title-winning engines for Red Bull and Racing Bulls.
• The current crisis centers on a severe vibration issue that is damaging critical components, particularly in the battery area, and has prevented race finishes.
• Despite the behind-the-scenes presence, the shift to a full works partnership with Aston Martin required a different, more integrated operational model that is still being developed.

What's next:

The immediate focus is on crisis management, not performance. Honda states it is working intensely with Aston Martin engineers embedded at its Sakura facility to implement a recovery plan aimed squarely at solving the vibration problems. The goal for the coming races is simply to finish, aiming to build a foundation of reliability before any performance gains can be pursued. This slow, step-by-step approach underscores the depth of the current technical deficit and suggests Aston Martin’s competitive aspirations for 2026 are already on hold.
