Overview
- FIA and F1 agreed a set of power and boost rule changes for use from the Miami Grand Prix, pending World Motor Sport Council approval, and extended first practice there to 90 minutes.
- Key tweaks cut maximum energy recharge to 7 megajoules and raise peak “superclip” boost to 350 kW to let drivers run flat out on qualifying laps and curb earlier straight‑line slowdowns during harvesting.
- New limits cap electric power to 250 kW in non‑straight sections and adjust boost timing so overtakes depend less on sudden power spikes and more on positioning and braking.
- Opinions remain split, with Sergio Perez saying even drivers and engineers struggle to understand the system, George Russell backing the changes and the driving feel, and Stefano Domenicali saying F1 is in great shape.
- David Coulthard warned Miami’s layout may hide the full effect of the tweaks, and teams are racing to adapt, with McLaren planning a near‑complete aerodynamic overhaul across Miami and Canada.
