Article 5.1
Power Unit Components
Chapter: Chapter I - Power Unit
In Simple Terms
F1 limits how many engine parts each driver can use per season to control costs. You get 3 of most components (engine, turbo, MGU-H, MGU-K) and 2 of others (battery, control electronics). Exceed these limits and you get grid penalties. Teams must balance performance versus reliability.
- 3 engines (ICE) per season
- 3 turbos, MGU-H, MGU-K per season
- 2 energy stores and control electronics per season
- Exceeding limits = grid penalties
Official FIA Text
