Overview

  • FIA officials said teams and engine makers agreed in principle to raise combustion output by about 50 kW, increase fuel flow, and cut electric deployment by about 50 kW from 2027.
  • The package still requires detailed work in technical groups, a vote by power unit manufacturers, and then a World Motor Sport Council e-vote before it is approved.
  • The Miami test of adjusted energy-use rules delivered better racing with no material safety issues, according to the FIA, though leading drivers said more fixes are still needed.
  • Further event tweaks are under review, including start procedure changes and wet‑weather safety measures, with Canada flagged as the next possible update point.
  • The move responds to problems with the 50/50 hybrid format introduced this season, highlighted by Oliver Bearman’s Suzuka crash after a rapid closing rate created by uneven battery deployment.
