The FIA approves targeted changes to Formula 1’s 2026 engine rules to aid Honda, confirming revisions after a delayed vote and World Motor Sport Council approval.
Honda sits well off the benchmark under the new framework. The FIA consults all power unit manufacturers, pausing pre-Miami to stress-test safeguards against unintended competitive leaps.
Central to the update is the ADUO mechanism. Manufacturers more than 10% down now access an $11 million upgrade allowance, up from an $8 million ceiling for 8% deficits.
FIA raises the ADUO cap to $11 million for manufacturers more than 10% off the benchmark.
A one-off, 2026-only, $8 million development budget supplements that allowance for eligible manufacturers.
Honda receives a unique, 2026-only, $8 million extra development budget.
Dyno capacity expands for strugglers, with permitted power unit bench running rising from 190 to 230 hours for those over the 10% threshold.
Honda supplies Aston Martin. The FIA frames the package as support without shortcuts, widening development room while protecting competitive integrity.
Timing also shifts. Bahrain and Saudi Arabia cancellations re-ordered the calendar, making Monaco the sixth round on June 7 and pushing the first evaluation too late.
