Overview
- Ben Sulayem, speaking Sunday at the Miami Grand Prix, said Formula 1 will revert to V8 engines by 2031 and could move a year earlier if enough manufacturers agree.
- A 2030 start would require a super‑majority of four of the six power unit suppliers, while the FIA can mandate the change for 2031 without a vote.
- The planned engines would keep only very limited electric assist, run on sustainable fuel, and put the combustion unit back as the primary source of power.
- The shift follows backlash to the 2026 near 50:50 hybrid units, which drivers say force lift‑and‑coast to recharge batteries and add weight and complex energy rules.
- Technical details and timelines are still being negotiated, with outlets reporting manufacturer openness and early estimates of sizable weight reductions that remain unconfirmed.
