F1 stakeholders agreed in principle to rebalance internal-combustion engine and energy-recovery system power for the 2027 power-unit rules, shifting roughly 50 kW of nominal power from ERS deployment to the ICE by allowing higher permitted fuel flow and reducing ERS deployment.

At an online meeting the FIA, team principals, Formula One Management and representatives of the five power-unit manufacturers outlined the package and said changes trialed at the Miami Grand Prix informed the proposal, improved on-track competition and did not produce material safety concerns.

Power-unit manufacturers must formally vote on any refined proposal and the World Motor Sport Council must complete an e-vote before rule changes are ratified. Detailed technical discussions will follow.
