Horner angered by Renault

(Bernard Asset DPPI for Renault Sport F1)

Infiniti Red Bull Racing team principal Christian Horner has heaped more criticism at the door of the reigning world champions engine supplier Renault following a yet another retirement for Sebastian Vettel. The reigning world champion lost power early in the race but regained soon afterwards however the Milton Keynes based squad opted for a strategic retirement for Vettel's RB10 rather then risk placing extra stress on car components that are at a critical point in their life.

Speaking to Sky Sports F1 following the team's home race Red Bull boss Christian Horner labelled Renault's performance as 'unacceptable'.

In an interview with Martin Brundle earlier this week, Red Bull's Motorsport director Dr Helmut Marko hinted that the team could potentially build their own engine's after 2015 however Horner has rejected this idea saying that the team have had a good relationship with Renault and that they have taken all of their Grand Prix victories with Renault power.

However, Horner did say that the issues that they have encountered this season:

'It’s been frustrating; we have had another issue today' But at the end of the day we have won four World Championships with Renault, we have won all our races with them. We’ve got to trust them to get on top of these issues.

While Vettel was forced to retire from the race, Daniel Ricciardo gave Red Bull some consolation by bringing his RB10 home in 8th place however the Australian can not be happy with that result having won the previous race in Canada which was his third podium in a row.

As a result of his retirement, Sebastian Vettel is now 23 point's behind Ricciardo in the championship as Red Bull head to their second home race at the British Grand Prix in Silverstone where they will be hoping for a better result. 

At the British Grand Prix last year, Sebastian Vettel retired from the race with a gearbox while Mark Webber who always went well there finished the race on the podium in second place behind race winner Nico Rosberg.
