F1 and FIA Agree to Add 50 kW ICE Power and Cut ERS for 2027

Context An online meeting on Friday brought together the FIA, team principals, Formula One Management and power‑unit manufacturers. The session reviewed safety and harvesting measures introduced at the Miami Grand Prix, which the FIA said improved competition and raised no safety concerns.

Key Facts - The FIA confirmed that the Miami refinements, aimed at limiting excessive energy harvesting, delivered tighter racing and will be further evaluated for future events, including start‑safety and wet‑condition protocols. - Participants agreed in principle to evolutionary changes to the 2026 rule set, focusing on hardware components that affect power delivery. - For 2027, the plan adds roughly 50 kW to internal‑combustion engine (ICE) power, raises the allowable fuel flow, and trims the Energy Recovery System (ERS) deployment power by about 50 kW. - Detailed technical discussions will continue before a formal proposal reaches the World Motor Sport Council for an electronic vote.

What It Means The modest ICE power boost restores some of the raw engine performance lost under the 2026 hybrid formula, while the ERS cut balances overall output to keep total power roughly constant. Teams will need to recalibrate power‑unit maps and cooling strategies to accommodate higher fuel flow and altered energy‑recovery limits. Drivers may notice a shift in acceleration characteristics, especially out of slower corners where ERS contribution is reduced.

The changes aim to make competition safer and more intuitive, according to the FIA, by simplifying power‑unit management and reducing reliance on complex energy‑harvesting tactics. If approved, the 2027 package could set a new performance baseline that influences car design, budgeting and driver development for the next five seasons.

Looking ahead, the technical groups will refine the proposals before the World Motor Sport Council votes, and the final rule package will shape the strategic direction of Formula 1 as it approaches the next regulatory cycle.
