FIA Announces Major 2027 Regulation Changes: More ICE Power, Less Battery Dependency

The FIA has agreed in principle to major changes for the 2027 season, shifting the power balance back toward internal combustion engines. The decision, reached in a meeting with team principals, F1 management, and engine manufacturers, aims to address driver complaints about power delivery and safety issues from the 2026 regulations.

Why it matters:

The 2026 cars have been criticized for their heavy reliance on battery power, leading to unpredictable acceleration and dangerous closing speeds under braking. The changes are designed to make racing more intuitive for drivers and safer, with a reduced risk of rear-end collisions. Incidents like Ollie Bearman's near-miss with Franco Colapinto in Japan highlighted the urgency. The Miami GP saw improvements, but top drivers called for more action.

The details:

• Power shift: ICE output will increase by ~50kW (67bhp) with a corresponding fuel-flow bump, while ERS deployment drops by the same 50kW. This reduces reliance on hybrid energy during racing.
• Timeline: Hardware changes mean these won't take effect until 2027, allowing time for further development and unanimous approval from power unit manufacturers.
• Safety focus: The FIA also confirmed further refinements to start procedures and wet-weather safety are under development, building on the Miami package that delivered 'a positive step'.

What's next:

The FIA will formally present the refined package for a World Motor Sport Council e-vote once manufacturers vote on it. Additional revisions are expected later this year as technical groups continue consultations with teams and drivers.
