The MGU-H uses the hot exhaust flowing through the turbocharger to generate power, which can be stored in the Energy Store (ES), essentially charging batteries. The process can also be reversed at times of low RPMs, when the MGU-H acts as a motor to spin up the turbocharger, thus greatly reducing throttle lag.

Also known as MGU-K, it is one of the six components of the power units. The MGU-K is directly connected to the crankshaft of the ICE, thus is charging the Energy Store (ES) via kinetic energy. The process is often reversed under acceleration, boosting power output, and in emergencies this unit can act as a starter motor.

Super License Penalty Points[edit | edit source]

As of the 2014 season, a penalty points system has been implemented whereby a driver may be given between one and three penalty points by stewards for various infractions. These penalty points accumulate but expire one year after they were earned. Any driver who accumulates twelve penalty points within a year will face a one race ban.
