Formula 1 teams back selective race-distance cuts from 2027, enabling a revised power unit concept. Agreement follows Miami discussions and targets a 60/40 combustion‑electric split, replacing today’s 50/50 balance.

The FIA pursues the shift, but higher fuel-flow targets lift race consumption. Larger tanks would be required, creating packaging problems for squads retaining current chassis under cost-cap constraints.

Rather than reopening the cap for clean-sheet designs, teams favour trimming distances at fuel-heavy venues. That approach mirrors recent F1 race options explored with stakeholders.

The working proposal removes one or two laps where necessary and restricts formation mileage from pit lane to grid to a single tour, reducing pre-race burn.

Racing Bulls boss Alan Permane says team principals align on the limited-scope cuts. The intent is to accommodate smaller tanks without undermining strategy variance or sporting integrity.

With chassis compromises manageable, the larger obstacle is power-unit cost. Re-optimising architectures for the 60/40 split could add roughly $10 million per manufacturer for design and manufacturing.

Newcomer Audi is cautious about that uplift amid defined budgets. Another flashpoint is the ADUO catch-up mechanism, which permits in-season updates to close performance gaps.

Opening homologation for redesigned units would render ADUO redundant and likely removed, an outcome Ferrari resists. Its stance reflects the ongoing doubts around the 2027 package across the paddock.

The broader regulatory trade-offs echo the 2027 rule challenge: balancing efficiency targets, manufacturer parity, and grid-wide cost discipline.

One compromise is modestly increasing fuel flow without wholesale redesigns, preserving race power while unlocking higher qualifying modes. That reduces retooling yet keeps the 60/40 trajectory intact.

Red Bull’s Laurent Mekies frames timing as the core risk. He says pressure is mainly on the power-unit side as Canadian meetings, with team upgrades, aim for convergence.

A decision window of weeks remains. Certainty is essential for 2027 schedules as suppliers freeze specifications and teams lock packaging, cooling, and fuel-cell layouts.
