F1 manufacturers Ferrari, Audi and Honda reject 2027 power‑unit rule change, prompting Verstappen criticism

At the Canadian Grand Prix, three of the five power‑unit suppliers—Ferrari, Audi and Honda—refused to give up their ADUO concessions, blocking the FIA’s plan to shift the hybrid power‑unit ratio to 60% internal‑combustion and 40% electric for the 2027 season. The agreement, which required support from at least four suppliers, now faces a possible delay until 2028.

Red Bull driver Max Verstappen warned that the dispute could affect his mental health, saying, “For mental health I cannot stay in F1 if the rule change is not made.” Other drivers expressed mixed views: Verstappen, Isack Hadjar and Lando Norris praised the move as a needed step, while Oscar Piastri highlighted battery‑balance challenges and Charles Leclerc called the changes insufficient and complex. The lack of consensus leaves the FIA uncertain whether it can implement the new regulations without the dissenting manufacturers.

If the stalemate continues, the sport may see further tension between teams, drivers and the governing body, with potential repercussions for the 2027 season schedule and technical development plans.
