Red Bull's Sebastian Vettel passed teammate Mark Webber in the closing laps of the Malaysian Grand Prix. The two drivers nearly collided on the front straight and through the first two turns of the Sepang circuit. But it quickly became clear the team wasn't happy about it. Team principal Christian Horner came on the radio to say "Come on Seb, this is silly."

After the race Webber was clearly unhappy with Vettel. "Multi 21, Seb. Multi 21" was the comment made by Webber to Vettel, a reference to the setting to turn down the engine. Red Bull's Horner said during post race interviews that both drivers were instructed to turn down their engines and hold positions to maximize the points. Vettel clearly ignored the order and later apologized to Webber and the team.
