Red Bull have become frustrated with Renault as their powertrain has been both unreliable and down on power compared to the Ferrari and Mercedes engine since the change in regulations at the start of 2014.
This has sent the four-time world champions down the pecking order and has hindered them by making it more difficult to fight for podiums and wins. In turn, this has caused public arguments between Renault and Red Bull as they blamed each other, causing their relationship to deteriorate.
Following this, Red Bull requested engine supply from Mercedes. This was rejected as Mercedes seem reluctant to aid one of their strong rivals and help it become more competitive and even bring to an end the domination they are enjoying.
This comes after Mercedes driver and World Championship leader, Lewis Hamilton, has made public his lack of interest to give the best engine to Red Bull, who are known for making great chassis.
This leaves Red Bull with the options of a Ferrari or a Honda engine. Red Bull have shown no interest in being supplied by Honda as they seem less competitive than Renault.
Ferrari seem to be the only viable option, as producing their own power train would not be possible by next year. Team principal of Ferrari, Maurizio Arrivabene, has stated that if necessary, they would provide engines to Red Bull. He was not concerned by the reputation Red Bull has for building very competitive chassis, the Italian said on BBC.
If Ferrari also reject a deal, Red Bull will be forced out of the sport with no engines.
