F1 hints at a major engine rule shift for 2031
Stefano Domenicali says F1 may drop the 50/50 hybrid V6 for lighter V8/V10 units on sustainable fuel, cutting cost and weight. FIA will start rule‑making this year, eyeing a 2031 debut.
F1 CEO Stefano Domenicali told The Race Podcast the sport may replace the 50/50 hybrid V6 with lighter V8/V10 units using sustainable fuel and modest hybrid assistance. Cost, weight and automotive relevance drive the push, with a new rule package aimed at 2031 but still flexible. This move would also align F1 with the broader shift toward sustainable mobility across motorsport.
Why it matters:
- Power‑unit cost is a major barrier; a simpler, lighter engine could cut team spending.
- Lower weight – smaller batteries and compact engines – improves car dynamics and aligns with road‑car trends.
- Weight reduction across the car could bring performance closer to road‑car targets, reinforcing F1’s relevance to manufacturers.
The details:
- Current rule: 50 % electric, 50 % ICE on a 1.6 L V6 hybrid (2026‑2029).
- Proposed switch: V8 or V10 engines with sustainable fuel and a reduced hybrid system.
- Cost pressure: power‑unit price is “too high”, prompting a push for cheaper solutions.
- Timeline: FIA will draft proposals this year, targeting 2031 but could move earlier if development allows.
What's next:
- FIA begins rule‑making in 2024, releasing a draft package later this year.
- Manufacturers will assess the proposal and may push for an earlier debut while sustainable fuel stays central.
