Renault will not supply power units for the Red Bull Formula One team after the 2018 season, ending a long-term relationship which included four driver and four constructors world championship titles.
By the end of 2018, Red Bull and Renault would have been partners for 12 seasons but, after a period of extreme success between 2010 and 2013, the relationship has soured somewhat since the introduction of the V6 hybrid power units.
Red Bull had been openly looking at other power suppliers in 2015 and 2016 but on each occasion, had been forced to return to Renault. With both Mercedes and Ferrari knowing the engineering capability of the team, it made no sense for them to supply engines to Red Bull -- a credible championship rival.

Somewhat out of the blue however, it is Renault who is pulling the plug. With the French manufacturer expected to be unveiled as McLaren's new supplier, Renault appears to be starting things from fresh.
Another factor in the decision could be that Toro Rosso, the junior Red Bull team, has left Renault to join McLaren's outgoing engine partner, Honda. The current speculation would suggest that Red Bull will also join Honda for 2019, working with the Japanese manufacturing giant throughout 2018 to get the best results possible.
The news is unlikely to be welcomed by drivers Daniel Ricciardo and Max Verstappen, both of whom are hungry for victories and to fight for the championship title.
