SAO PAULO, Nov 26: Red Bull’s Sebastian Vettel became Formula One’s youngest triple world champion at the age of 25 after a wet and chaotic Brazilian Grand Prix rollercoaster won by McLaren’s Jenson Button behind the safety car on Sunday.

The German, needing only a fourth place to join the greats as the first driver to win his first three titles consecutively, finished sixth after fighting back with a damaged car from last on the opening lap.

It proved enough after his sole rival Fernando Alonso, needing victory, crossed the line in his Ferrari in second place with Brazilian Felipe Massa third.

Vettel ended the season with 281 points to 278 for Alonso, who would have been the youngest triple champion at 31 had results fallen his way. Kimi Raikkonen was third overall for Lotus on 207 in his comeback year.

Red Bull had already won the constructors’ title for the third year in a row.

On a day when the Brazilian weather produced a thriller to stand the test of time against some of the sport’s great races, it seemed the gods were on Alonso’s side almost as soon as the starting lights went out.

Vettel was squeezed from fourth place, fell back into the pack and was caught in a collision with Brazilian Bruno Senna’s Williams that spun him around helplessly facing his speeding rivals.

Four laps later Vettel was assured the data looked good but a concerned-looking Red Bull technical head Adrian Newey had a photograph of the damage taken at the driver’s pitstop to get a closer look from the pit wall.

Alonso, Vettel’s only title rival who had 13 points to make up, looked like he could steal it as the championship pendulum swung both ways over the 71 laps at Interlagos.

The safety car was deployed twice, there were crashes, collisions, botched pitstops and constant uncertainty about the weather with black clouds overhead, occasional rain but not the torrential downpour many had feared.

Seven-time world champion Michael Schumacher took seventh place for Mercedes in his last race in Formula One, moving over to allow his friend and compatriot Vettel to take sixth and join him as one of only three drivers to win three titles in a row.
