Formula 1 stakeholders have agreed to increase internal combustion engine power starting in 2027 to address energy management issues in the new power unit rules.
The FIA announced the changes on Wednesday following discussions among F1 management, teams and power unit manufacturers. Power units will see fuel flow rise by five percent next year, lifting ICE output from 400kW to 420kW. Electric motor maximum power will drop from 350kW to 300kW while overtake mode stays at 350kW and the harvesting limit increases to 375kW. A larger 13 percent fuel flow increase, raising ICE power to 450kW, is set for 2028 to reach a 60/40 power split. The maximum harvest limit will then rise further to 400kW. Tweaks were also made to the power unit financial regulations to provide cost cap headroom. The proposed amendments will go before the FIA's World Motor Sport Council for ratification on June 23 in Macau. The FIA stated that the 2026 regulations were developed in partnership and that the latest adjustments continue this collaborative effort to refine the framework.
