Formula 1 power unit regulations state:

• Unless he drives for more than one team, each driver may use no more than four power units during a championship season. The only exception is where the power unit is provided by a manufacturer or supplier taking part in its first championship season, in which case up to five may be used by a driver.
• The power unit is deemed to consist of six separate elements: the internal combustion engine (ICE), the motor generator unit-kinetic (MGU-K), the motor generator unit-heat (MGU-H), the energy store (ES), turbocharger (TC) and control electronics (CE).
• Each driver is permitted to use only four of each of the above six elements during a championship season and any combination of them may be fitted to a car at any one time. Should a driver use more than four of any of the six power unit elements during the course of a season, a grid penalty will be imposed.
• The penalties imposed for using additional elements work thus: the first time a fifth of any of the elements is used, a ten-place grid penalty will be imposed. A five-place grid penalty will then be imposed the first time a fifth of any of the remaining elements is used. Likewise, the first time a sixth of any of the elements is used, a ten-place grid penalty will be imposed, and so on.
• During any single event, if a driver introduces more than one of a power unit element that is subject to a grid penalty, only the last element fitted may be used at subsequent events without further penalty.
• If a driver is replaced at any time during the season his replacement will be deemed to be the original driver for the purposes of assessing power unit usage.
• Teams may only use homologated power units.
