This season drivers have been limited to four of each of the engine components, after which they began to rack up penalties.
This came to a head at the Italian Grand Prix where seven drivers were penalised for use of additional power unit elements while two were handed gearbox penalties.
But despite many in the Formula 1 paddock admitting that something needs to be done about this, the FIA has reduced the number of engine components that drivers can use without penalty for 2018.
Article 23.3 a) of the 2018 Sporting Regulations, states: “Unless he drives for more than one team, each driver may use no more than 3 engines (ICE), 3 motor generator units-heat (MGU-H), 3 turbochargers (TC), 2 energy stores (ES), 2 control electronics (CE) and 2 motor generator units-kinetic (MGU-K).
“Should a driver use more than the numbers set in a) above of any one of the elements during a Championship season, a grid place penalty will be imposed upon him at the first event during which each additional element is used.”
