ICE – Internal Combustion Engine, TC – Turbo Charger, MGU-K – Motor Generator Energy-Kinetic, MGU-H – Motor Generator Energy-Heat, ES – Energy Store, CE – Control Electronics.
FIA regulations state that each driver may use no more than five power units during a championship season.
The power unit is deemed to consist of six separate elements, of which five of each are available to each driver per season before they are penalised.
The elements are the engine, the motor generator unit-kinetic (MGU-K), the motor generator unit-heat (MGU-H), the energy store (ES), turbocharger (TC) and control electronics (CE). Should a driver use more than five of any one component he faces a penalty ranging from a five-place grid drop, a 10-place grid drop, or (if the entire power unit has to be changed) starting the race from the pit lane.
Toro Rosso’s Daniil Kvyat the only man ow used all of his five allowed Internal Combustion Engines (ICE) and Motor Generator Units – Kinetic (MGU-K), these units now have to last for the remaining ten race weekends if he is to avoid a grid penalty.(ThisisF1)
