What's happened
The FIA, F1, teams and engine suppliers have agreed in principle to regulate a bigger internal-combustion engine share from 2027 as Miami hosts one of the most open races in recent memory. The changes aim to let drivers push harder by increasing ICE power and adjusting energy recovery. Formal approvals are pending.
What's behind the headline?
Context and implications
- The current 50-50 ICE-to-electric split is being adjusted toward a 60-40 ICE bias for 2027, with higher fuel flow and lower ERS deployment. This is intended to let cars run at higher straight-line speeds without excessive energy harvesting penalties.
- Drivers have criticized the energy-management constraints, arguing they dampen on-track performance and approach to overtaking. The Miami event has amplified calls for clearer, more consistent rules.
- Upgrades arriving for several teams in Florida indicate a broader arms race; pace across teams remains mixed as engineers adapt to new power balance and potentially larger fuel tanks.
- Leadership emphasizes safety and driveability, but some teams and drivers foresee the need for longer-term hardware redesigns beyond 2027, including possible engine-type changes.
Forecast
- Approvals will hinge on detailed evaluation by the Formula 1 Commission, power-unit advisory committee and the FIA World Motor Sport Council. If approved, the 2027 package will shape the rest of the decade and influence driver strategy and race dynamics.
How we got here
The Miami Grand Prix has become a focal point for a broader regulatory rethink in 2026, with mid-season tweaks to energy management and discussions about returning to larger ICE emphasis in the near future.
