Formula One team's are set to be allowed to use a fifth power unit in 2015 if the need arises without incurring a penalty.
This season it was decided to reduce the number of power units from five to four. The team's met on Friday however and decided to leave the current allocation as it is.
The idea still needs to ratified by the FIA. The news will come as a relief to Infiniti Red Bull Racing as Daniil Kvyat is already down to three power units following his failure in Melbourne two weeks ago.
