Overview
- Negotiations over 2027 power‑unit changes are active but unresolved, with leaders pressing for a compromise before the Spanish Grand Prix on June 12–14 to fix this season’s lift‑and‑coast, super‑clipping and battery‑depletion problems.
- The FIA floated a large option to raise fuel flow by about 14 percent to move combustion/electric balance toward roughly 60/40, but that proposal has provoked private objections from several manufacturers who say the hardware and timeline make it infeasible.
- A lower‑impact compromise under discussion would raise fuel flow by about 5 percent and cut aerodynamic downforce by 40–50 points to reduce energy saving techniques without forcing major engine redesigns.
- FIA president Mohammed Ben Sulayem has publicly committed to exploring a return to V8 engines on sustainable fuel for the 2030–2031 rules cycle, but any architecture change would need approval from at least four power‑unit manufacturers.
- Manufacturers are split on priorities: Audi and Honda stress cost control, efficiency and stability and prefer solutions that avoid new hardware, while some teams and drivers support stronger combustion to restore on‑track performance and sound.
