Not content with dominating F1 on track at the moment, Red Bull Racing is now claiming a new speed record for one of its pit-stops in Sunday's US Grand Prix.

The team has been vying with Ferrari for the right to proclaim themselves king of the tyre change but, even as Sebastian Vettel was cruising to an eighth successive win, this time at the Circuit of the Americas, the backroom boys were doing their stuff on team-mate Mark Webber's car, turning the Australian around in less than two seconds as he raced his way to third place.

While TV timing suggested that the four-wheel change had taken a shade over two seconds, RBR's own system produced a more favourable figure.

"The car data recorded Mark as being stationary for just 1.923secs, an incredible feat," the team wrote on its official website, announcing that it had broken its own unofficial record, claimed for a 2.05secs turnaround of Webber in Malaysia earlier this season.

At that time, Red Bull suggested that a sub two-second stop was possible, although the champions insisted that it would not be chasing a record, preferring to concentrate on efficiency and consistency and let the times come down as a result of that.
