Renault should seek help from Mercedes and be trying to make its relationship with Red Bull work, according to Bob Fernley.
Red Bull is threatening to quit F1 after ending its partnership with Renault a year early having been frustrated with a lack of competitiveness from the French manufacturer's power unit. Renault looks set to take over Lotus and return as a manufacturer, but it is still facing a power deficit.
With Red Bull's options running out after Mercedes decided against supplying it with power units, Fernley says he has little sympathy for the four-time constructors' champions, while also hinting Mercedes helped Ferrari improve its own performance over the winter.
“I think there has been mistakes made by both Renault and Red Bull and they should sit down together and try to work it out," Fernley told F1i. "The Renault engine is capable of moving on to a much better performance unit a la Ferrari. Maybe a bit of help from Mercedes as Ferrari got or something and they could be there. So I think that was perhaps an error on their part."
With Red Bull boss Dietrich Mateschitz already having confirmed the Renault partnership will end after this season, Bernie Ecclestone admits he is facing a difficult task to keep Red Bull in F1.
