Note: Drivers are able to use five of the new power units this season. However, this is more complicated than it first appears since the power unit is deemed to comprise six elements, which can be moved between units should the need arise.

Drivers are able to use five of each of the following: the 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 element can be rotated among units.

However, should a driver use more than five of any one of the elements a grid penalty will be imposed at the first event during which each additional element is used. The first time a driver uses a sixth element, a ten-place grid penalty is imposed. Different sixth elements used later will incur a five-place grid penalty. The first time a driver uses a seventh element, a ten-place grid penalty will be imposed. Different seventh elements used later will incur a five-place grid penalty and so on...

If a grid penalty is imposed, and the driver's grid position is such that the full penalty cannot be applied, the remainder of the penalty will be applied at the driver's next race. However, no remaining penalties will be carried forward for more than one race.
