Red Bull unveil new car only for oil leak to halt Mark Webber in test

Red Bull, a favourite to win the world championship, unveiled its 2010 car today but soon ran into trouble at the start of the second official Formula One test at Jerez. Mark Webber completed 47 laps in wet conditions before coming to a halt on the Spanish track with an oil leak. While such problems should be no surprise on the first running of a new car, Ferrari and Sauber, the pace-setters during last week's test in Valencia, ran with only minor problems first time out. It took four hours to fix the Red Bull, Webber rejoining with 40 minutes remaining to set the ninth-fastest time of the 10 runners. Red Bull were runners-up to Brawn in the 2009 championship. "To go forward from there we need everything right and that is what we've tried to do as best we can," said Webber before venturing out in the RB6, an evolution of last year's successful RB5. "We're very excited, we've worked hard and there has been a lot of anticipation." The fastest times today were set in the first 50 minutes, the only period during the day-long session when the track was dry, making lap times less significant than usual. Nico Rosberg was quickest but the German's day ended when his Mercedes stopped on the track with 10 minutes remaining. Michael Schumacher will take his turn in the Mercedes when testing resumes tomorrow morning. The FIA has denied reports that teams, particularly this year's four new entrants, will be allowed to miss three races. The sport's governing body said: "Following recent reports on the interpretation of clauses in the Concorde agreement concerning the concept of a team's 'participation' in the FIA Formula One world championship, the FIA wishes to make the following clarification. "Each team that has registered for the championship is obliged to take part in every event of the season. Any failure to take part, even for just one championship event, would constitute an infringement both of the Concorde agreement and the FIA regulations." Virgin Racing was the first of the newcomers to appear on track today but Timo Glock was restricted to just three laps after the British team had to wait most of the day for the final parts to be fitted to the Cosworth-powered car.
