FIA reveals major change to F1 regulations for 2027

The FIA has announced an in-principle agreement to adjust F1's 2027 regulations, tilting the power balance away from batteries and back toward internal combustion. The changes, approved with teams and engine manufacturers, will increase ICE power by ~50kW (67bhp) alongside a fuel flow increase, while reducing ERS deployment by the same amount. This course correction addresses driver complaints about excessive energy harvesting and the safety risks it creates under braking.

Why it matters:

The 2026 regulations introduced a heavier reliance on hybrid power, but drivers found it made racing less intuitive and caused dangerous closing speeds. The Bearman-Colapinto near-miss at Suzuka forced a rethink. These 2027 tweaks aim to restore driver control and improve on-track action by rebalancing the power unit.

The details:

• Power shift: ICE output increases by ~50kW; ERS deployment decreases by ~50kW, with a corresponding fuel flow increase.
• Timing: Changes delayed to 2027 due to hardware modifications required.
• Safety context: Rapid closing rates under braking, driven by energy harvesting, were a key concern. Haas driver Oliver Bearman had to take evasive action to avoid Franco Colapinto's Alpine at Spoon Curve during the Japanese Grand Prix.
• Miami update: A recent package introduced at the Miami Grand Prix improved competition and safety, but top drivers said more was needed. The FIA confirmed no material safety issues were identified in Miami.
• Further revisions: The FIA is evaluating additional adjustments for future events, including improved start-safety and measures for wet conditions.

What's next:

The final package will be refined in technical groups with teams and power unit manufacturers. Once the manufacturers vote on it, the proposal will go to a World Motor Sport Council e-vote. More regulatory revisions are expected throughout 2026.
