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

Each driver may use no more than 3 internal combustion engines (ICE), 3 motor generator units-heat (MGU-H), 3 turbochargers (TC), 3 motor generator units-kinetic (MGU-K), 2 energy stores (ES), 2 control electronics (CE) during the Championship.
