SINGAPORE (Reuters) - Former world champions Red Bull and engine supplier Renault are set to part company after the 2018 Formula One season, media reports said on Thursday.
The two have had a fractious relationship since a new 1.6 litre V6 turbo hybrid power unit was introduced in 2014 and Renault's version proved less competitive than that of rivals Mercedes.
