Overview
- A planned vote to relax F1’s catch‑up rules for power units was pulled after the count, leaving Honda’s bid for extra in‑season help unresolved.
- The proposal under review would lift ADUO’s current in‑season cap so a lagging supplier could receive more than one upgrade round and added budget and dyno time.
- Under today’s ADUO rules, a 2% power deficit unlocks one 2026 upgrade and one for 2027, while a 4% gap grants two this year and two next year, and those upgrades do not stack within a season.
- The FIA is still finalising how and when it will apply ADUO, using lap‑weighted power from each maker’s best car, with the first usable results expected after Miami and Canada.
- Honda’s Aston Martin unit has suffered vibration‑related performance and reliability issues, and after testing an AMR26 at Sakura it plans countermeasures for Miami but does not expect an immediate power gain.
