Overview
- FIA officials approved targeted changes to rein in battery use that had forced drivers into mid‑lap power cuts and created dangerous speed gaps, with Miami serving as the first on‑track trial.
- Core updates cut maximum recharge per lap and raise short‑burst output to shrink “superclipping,” cap electric deployment in corners to 250 kW, and introduce a tighter start detection and new wet‑weather parameters.
- A software rule closes a loophole in the power‑limited phase by requiring the throttle to stay above 98% for one full second before reduced‑power mode can engage.
- Teams return from the break with upgrades, as McLaren readies an almost new car, Ferrari brings a major package, Red Bull seeks a reset, and Mercedes arrives on top with teenager Kimi Antonelli leading the standings.
- Miami’s sprint format includes an extended practice to help teams adapt, heavy Sunday thunderstorms are in the forecast, and the FIA says further tweaks are possible after it reviews race‑weekend data.
