Jul.16 (GMM) Sebastian Vettel's scheduled attendance at the Ennstal-Classic rally in Austria this weekend has been called off by his formula one employer Red Bull.
Instead, the 22-year-old German has been summoned to the Idiada Proving Ground, near Barcelona, for testing of the title-contending RB5 single seater.Vettel's Nurburgring-winning teammate Mark Webber will also be there on Saturday, as the Milton-Keynes based team attempts mainly to improve the car's efficiency from a standing start."The world championship is entering a crucial stage," team adviser Dr Helmut Marko told Germany's Sport Bild."That a test like this has priority (over the Ennstal-Classic) is clear to us. Obviously it is a shame, but we are talking about the world championship," he explained.
