SILVERSTONE, England - Red Bull has asked if it can follow Mercedes' lead and conduct a 1000km tyre-test with Pirelli using its 2013 car.Red Bull was very critical of the Mercedes test for which it was banned from the forthcoming young drivers test but the International Automobile Federation has since clarified that.So long as Pirelli and F1 teams follow the right processes, such tyre tests are actually allowed.F1 'PEACE SUMMIT' SNUBBrazilian F1 correspondent Livio Oricchio reports that Christian Horner has asked the governing body if it can be the next team to test.Oricchio said: "Horner is convinced, that the 1000km of testing that Hamilton and Rosberg did in Barcelona had a direct effect on Mercedes' rapid development in the last few races."A report by Speed Week read: "Red Bull has sent a detailed letter to race director Charlie Whiting to clarify the question: 'under what circumstances can we also go testing?'"There's palpable tension between Mercedes and Red Bull. Mercedes' Toto Wolff insists that some quotes about Red Bull in the media were taken out of context but according to Bild newspaper, he had agreed with Pirelli to sit down for a "peace summit" at Silverstone.Red Bull's Christian Horner, however, refused to attend: "That was not a good idea. The tribunal is over and we want to look forward."Wolff responded: "It's a shame Christian declined. I would have liked to talk about the tribunal, maybe clear up some things, get closer together once again."
