Overview
- The Formula 1 Commission agreed on Tuesday to add a fourth pre‑season test day for 2027, subject to approval by the FIA World Motor Sport Council, to give teams more time to assess reliability if power‑unit changes proceed.
- Commission members approved minor aerodynamic and bodywork tweaks plus tighter limits on Testing of Previous Cars to stop teams from gaining race‑specific development advantages.
- The central proposal to shift from the current near‑50:50 ICE/electric split to a 60/40 balance did not win the required supermajority of power‑unit manufacturers, leaving the rule change stalled for 2027.
- Multiple reports say Audi, Honda and Ferrari have resisted the 2027 rebalance, with disagreement also tied to whether the FIA will publish relative ICE power figures and grant Additional Development and Upgrade Opportunities.
- Drivers including Max Verstappen and Fernando Alonso continue to press for a higher ICE share because the 2026 hybrid package has increased car weight and forced energy‑management driving, and teams are considering measures such as higher fuel flow, larger tanks or shorter races to avoid costly chassis redesigns.
