The family feud otherwise known as Formula One's Red Bull Racing team heads to China, with all eyes on its drivers Sebastian Vettel and Mark Webber.
Vettel, the reigning Formula One champion, and Webber could barely look at each other after the Malaysia Grand Prix two weeks ago, when Vettel snatched victory from his Australian teammate.
Webber, 36, was leading Vettel in the race's closing stages when, in one of the unique traits of Formula One, his team instructed the drivers to stay put and conserve their tires until the race was over.
The 25-year-old Vettel ignored the order, passed a stunned Webber for the win and in the post-race news conference awkwardly tried to explain himself. "I made a mistake, I'm not proud that I made it," Vettel said.
