FIA outlines 2027 F1 rule tweaks: more ICE power, less ERS, votes pending

The FIA has announced a planned shift for the 2027 F1 rules away from the current roughly equal split between combustion and electric power, with internal-combustion engine power set to rise by about 50 kW via a higher fuel-flow, while the Energy Recovery System (ERS) deployment power would be reduced by about 50 kW. The proposals are agreed in principle but still require votes from power-unit manufacturers and a World Motor Sport Council approval, with further technical discussion and possible hardware changes to the power unit. The package builds on earlier Miami tweaks aimed at improving safety and competition around energy harvesting.
