Sebastian Vettel and Red Bull rage back into the F1 limelight

Sebastian Vettel and Mark Webber stood next to each other and smiled at the same moment today, which was not forever the case for grand prix racing's new world champion and his team-mate last season, when both drivers went into the final race with a possibility of the title at the end of an internecine battle that had sometimes turned sour and was intended to finish in the young German's favour.

A new season began with the ceremonial presentation of the successor to the Red Bull-Renault that gave the team a clean sweep of the drivers' and constructors' championships. Both men, at opposite ends of their careers, could feel a surge of optimism by what was revealed when they pulled the dust sheet off the descendant to the all-conquering RB6, and again when Vettel ended the day with the fastest time of the field, having hammered the car around 93 laps of the taut little circuit in the semi-industrialised scrubland west of Valencia.

Formula One's new champion dismissed the close-season rumours connecting him with a move to Ferrari. "It's not smart to put too much weight on those things," he said. "In the off-season there are no wheels rotating, unfortunately, but obviously there are still pages to be packed with ink. I said many times I am happy where I am. I feel very relaxed in the team."
