Jenson Button and his Brawn GP team were crowned Formula One champions with a race to spare in an action-packed Brazilian Grand Prix won by Red Bull's Australian Mark Webber Sunday. Button finished fifth to become Britain's 10th world champion, with closest rival and teammate Rubens Barrichello suffering a late puncture and crossing the line eighth after starting his home race on pole position. Button, who belted out an off-tune “We Are The Champions, My Friends” over the team radio on his slowing down lap, was ecstatic after a rain-hit qualifying session had left him starting 14th. “Oh what a race. I am world champion, I am world champion. It's been such an interesting season,” he said, embracing his mechanics before a congratulatory hug from Formula One supremo Bernie Ecclestone. “It is really amazing. Today was such an awesome race and I am world champion. I never expected to be world champion in Formula One.” “I think he (Button) can sleep better now because he's been absolutely bricking it after the last few races,” Webber said with a smile. “He can enjoy (the last race in) Abu Dhabi.” Red Bull's Sebastian Vettel, the 22-year-old German who needed to finish in the top two to have a chance of staying in contention for the title, took fourth place on a hot and humid afternoon at Interlagos. Button, winner of six of the first seven races, now has 89 points to Vettel's 74 and Barrichello's 72. Brawn, which needed only a point to be sure of the constructors' championship, became the first team to take the crown in its first full season. Poland's Robert Kubica was second for BMW-Sauber with McLaren's outgoing world champion Lewis Hamilton taking third place from 17th on the grid at the circuit where he clinched the title in a 2008 thriller. The safety car was deployed for four laps after chaos on the opening lap when Force India's Adrian Sutil, Toyota's Jarno Trulli and Renault's Fernando Alonso crashed out. Trulli and Sutil, who had been third on the grid, then had a heated argument on the run off with the Italian clearly feeling more aggrieved. McLaren's Heikki Kovalainen finished the race with a stewards' investigation still pending after he left the pits with the fuel hose still attached, spraying fuel over Kimi Raikkonen's Ferrari. The fuel then ignited, causing a flash fire near the pit lane wall. Button, who had prayed for dry conditions after the deluge Saturday, was by then on a charge and putting it all on the line, overtaking Renault's Romain Grosjean, Williams' Kazuki Nakajima and Toyota's Kamui Kobayashi. Nakajima crashed spectacularly on lap 31 after touching Kobayashi's rear wheels. McLaren was later fined $50,000 for the incident that sprayed fuel over Raikkonen's Ferrari and triggered a flash fire in the pit lane. Its Finnish driver Heikki Kovalainen was also handed a 25-second penalty, to be added retrospectively to his race time, for an unsafe release in which he trailed the fuel hose behind his car. The stewards also fined Trulli $10,000 and reprimanded the Toyota driver for aggressively confronting Sutil after they collided and crashed out on the opening lap.
