ICE = Internal combustion Engine
TC = Turbo Charger
MGU-K = Motor Generator Unit - Kinetic
MGU-H = Motor Generator Unit - Heat
ES = Energy Store
CE = Control Electronics

Note: Drivers are able to use four 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 four 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.
