The FIA has increased the allocation of permitted power unit components for the first time in Formula 1’s hybrid era, with drivers allowed a third MGU-K in 2020.
The power unit comprises six components – the Internal Combustion Engine, Turbocharger, MGU-H, MGU-K, Energy Store and Control Electronics – and the number of permitted parts has reduced over time.
For 2019, drivers were permitted three ICEs, Turbochargers and MGU-Hs, while the MGU-K, Energy Store and Control Electronics usage was reduced to just two.
On Wednesday the FIA’s World Motor Sport Council met to formally ratify the change, meaning that drivers will be allowed three MGU-Ks per year, prior to taking a penalty.
The WMSC also confirmed the appointment of BBS as the single supplier of wheel rims, starting in 2021.
The ratification of Magneti Marelli as fuel primer pump supplier, and Bosch for the high-pressure fuel pump and piping, was also confirmed, following the FIA’s consultation with teams and power unit suppliers.
