Power unit component limits
Each driver may use a limited number of engine elements per season (ICE, MGU-K, MGU-H, turbo, battery, control electronics). Exceeding the allocation triggers grid penalties that increase with each extra component.
How multiple penalties combine
The FIA applies penalties in a defined order. Several five-place drops can stack; beyond a threshold a driver may be sent to the back of the grid or start from the pit lane.
The published starting grid on Sunday morning is the authoritative order after all penalties.
Other common penalties
Gearbox changes outside the allowed cycle, impeding in qualifying, ignoring yellow flags, or technical infringements can also cost grid positions or in-race time penalties.
