Overview
- The 60/40 proposal to shift power‑unit output by +50kW to the internal combustion engine and −50kW from the battery was floated after the Miami talks and was discussed in Montreal this weekend, but it currently lacks the four of six manufacturer approvals required to be ratified.
- Manufacturers such as Audi have warned the changes could cost more than $10 million and strain suppliers, and teams say higher fuel flow would force larger fuel tanks and possibly new monocoques for cars planned to be carried over.
- Reopening engine homologation for 2027 would conflict with F1’s ADUO catch‑up system, prompting caution from teams that view ADUO as their main route to close power deficits.
- To avoid immediate, costly hardware work, paddock reports say a compromise is emerging to make only moderate fuel‑flow increases for 2027 and defer a full 60/40 hardware revamp to 2028 if manufacturers cannot reach consensus.
- Drivers and some team bosses back faster change to reduce extreme energy management, and Max Verstappen has confirmed he plans to race in 2027 if the rule direction improves, with reports suggesting an exit clause in his contract that could be triggered at the summer break.
