Overview
- The FIA has formalized rebalanced technical rules for 2027 to ease the operational problems of the 2026 turbo‑hybrid era by raising fuel and ERS energy and simplifying underfloor aerodynamics.
- FIA president Mohammed Ben Sulayem is pressing for a naturally aspirated V8 with a small kinetic energy recovery system and much smaller batteries to reduce car mass and restore louder engine sound.
- Engine makers are divided: Audi is reluctant to abandon forced induction after recent investment while Mercedes and others are broadly more open to the V8 direction.
- Reintroducing mid‑race refuelling is being discussed as a practical way to shrink fuel tank size and cut roughly 50kg from car mass, but it raises logistical and sustainability trade‑offs.
- The governing body wants a weight target near 700kg and reduced hybrid contribution of about 10–20% of ICE output, and it can either seek a voluntary 2030 switch with four of six suppliers or impose a unilateral 2031 solution.
