Daniel Ricciardo: 7/10
A hugely frustrating season so far for Ricciardo, who was priming himself for an assault on the title having been best of the rest in 2014. The car has been off the pace but Ricciardo has also failed on occasion, most notably in Canada where he was comfortably beaten by team-mate Kvyat. Despite the struggles, Ricciardo has led the team well, remaining positive for the majority of the time but also not afraid to speak out when he feels necessary. Adding a fourth win to his tally has been a distant dream everywhere except Hungary, but the improvement in recent races will give him confidence there is a better second half of the season in store.
