- F1 and the FIA, team bosses and engine manufacturers agreed in principle to shift the 2027 power split to roughly 60% ICE and 40% ERS, adding ~50 kW to the internal combustion engine and cutting ~50 kW from the ERS.
- FIA said the 2027 changes will also raise fuel‑flow limits and will be refined by technical groups before the final package is voted on.
- Power unit manufacturers will vote on the final package, after which the World Motor Sport Council will formally approve the changes.
- Miami Grand Prix regulation tweaks introduced the previous week were deemed successful in improving driver experience and safety, and stakeholders agreed to keep them.
Why it matters: Teams must redesign power units by 2027, incurring extra R&D costs, but drivers will have a more intuitive throttle response, potentially improving lap times and spectators’ enjoyment.
