Sao Paulo: Red Bull's Mark Webber won his first race of the Formula One season in the Brazilian Grand Prix here Sunday, while Force India ended the year on a high with Adrian Sutil and Paul di Resta finishing sixth and eighth at the Interlagos Circuit.Already declared World Champion Sebastian Vettel was in the lead until Lap 30 from the record pole position but a gearbox problem in his Red Bull forced him to make way for teammate Webber.

The Australian eventually crossed the chequred flag 16.9 seconds faster than Vettel. Jenson Button got his McLaren home in third place, ensuring him a second place in the drivers' standings with 270 points in 19 races.

Vettel had bagged the title in Japan but the battle for the second and third went right down to the last race. A win for Weber here puts him third in the standings with 258 points, only one more than Ferrari's Fernando Alonso.

Force India achieved their best result since their inception in 2008 by finishing sixth in the Constructor's Championship with Sutil securing the ninth place and di Resta coming 13th in the drivers' standings. The team finished at seventh place in 2010.

Sutil and di Resta's impressive result from eighth and 11th grid position meant the Silverstone-based team completed a double points finish only for the fourth time in the season after Australia, Singapore and Abu Dhabi.

Lewis Hamilton's rollercoaster season ended in disappointment when a gearbox problem forced him into retirement.

The 2008 world champion, who finished fifth overall in the championship, pulled his McClaren off to the side of the Interlagos track on the 48th lap.

"I think it's been an interesting year. Today, I gave it my all. I enjoyed the race and it's a little bit unfortunate that we weren't able to get extra points," Hamilton told the BBC.

"I was challenging Felipe (Massa) at the end and was hoping I could get him but the gearbox didn't last. It's been a long, long year and I'm looking forward to a little bit of downtime with family and friends.

"There is a lot to improve on but I feel it's all positive even though we didn't have a great result today."

Seven-time champion Schumacher of Mercedes had a punctured left-rear tire while trying to pass Bruno Senna of Renault at the end of the main straight.

Schumacher had already got past Senna when the Brazilian's car touched his tire and forced him to make an unscheduled pitstop that led to a 15th-place finish.
