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).
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.
