Overview
- In early June FIA president Mohammed Ben Sulayem publicly committed to bringing V8 engines back to Formula 1, saying a switch should happen ideally by 2030 and certainly by 2031.
- The FIA and Liberty are pressing for a faster 2027 fix that would move the power split from near 50:50 to about 60:40 by boosting fuel flow and ICE output, with a target to agree details before the Spanish Grand Prix and the PUAC meeting on June 14.
- A small group of power‑unit manufacturers is split: Audi and Ferrari have raised last‑minute concerns about cost, timing and ADUO rules that make large 2027 hardware changes difficult, while Mercedes and Red Bull back a larger rebalance.
- On‑track failures under the 2026 hybrid formula — notably battery saturation that prevents harvesting and causes turbo lag on low‑speed exits in Monaco — are increasing urgency for a workable compromise.
- If a long‑term move to V8s proceeds it will need a manufacturer supermajority, would reshape vehicle packaging and costs, and could force interim measures such as smaller fuel‑flow tweaks or aero changes if a 2027 hardware pivot proves infeasible.
