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
