Vettel gives Red Bull their wings

German Sebastian Vettel gave Red Bull their first Formula One win at a Chinese Grand Prix that was like "driving in a river".The 21-year-old claimed the second victory of his career with Australian teammate Mark Webber taking his own best result in a Red Bull one-two on a track that resembled a skidpan for much of the race."Getting the top two for Red Bull is incredible, I'm extremely happy," said Vettel, who took nearly two hours to complete the 56 laps."It was extremely challenging, there was a lot of aquaplaning ... really hard to keep the car on the track, sometimes it was like there was a river running down the track."Webber, who is a director of the Grand Prix Drivers' Association, said the race had been "right on the edge in terms of safety"."Very tough race, very difficult conditions but a very rewarding result," said the 32-year-old, whose previous best result was third.Briton Jenson Button, who won the first two races of the season, finished third to extend his championship lead to six points over Brawn GP team mate Rubens Barrichello, who was fourth."It's a great result for me," said Button, who now has 21 points."The problem is you can't see the car in front or the car behind, it's really quite dangerous."McLaren's Heikki Kovalainen was fifth to get his season going at last after failing to finish a lap in the previous two races, while world champion team mate Lewis Hamilton finished sixth after a late spin robbed him of a better result.
