Vettel clinches second F1 title as Button wins the Japanese Grand Prix

The result was Button's first win for McLaren in a totally dry race, and while Vettel's Suzuka winning streak ended, the Red Bull man's podium finish was still more than adequate to make him the champion for a second consecutive year.

Vettel clearly would have preferred to clinch his title with a win - underlining his determination by very firmly defending his lead against the faster starting Button off the line. The McLaren had to flirt with the grass in the close call, prompting Button to enquire over the radio whether Vettel ought to get a penalty. The incident was investigated, but no action was taken.

As Button lost momentum, his team-mate Lewis Hamilton swept around the outside of him into second, where he would stay until signs of a right rear puncture forced him to slow abruptly and make a slightly early pitstop at the end of lap seven. This would drop Hamilton to fourth once the first stops were completed, behind Alonso - who had passed his Ferrari team-mate Felipe Massa into the first corner early on.

Button was keeping his tyres in better shape than Vettel, and closed right in on the Red Bull at the end of the stint. Vettel pitted a lap earlier and stayed ahead in the first stops - but not in the second stops on laps 19 and 20, where Button's superb in-lap pace and a great McLaren stop got the Briton out in the lead.

The safety car came out shortly afterwards to clear some debris, including a chunk of Massa's Ferrari bodywork deposited at the chicane when he made contact with Hamilton while trying to go around the outside of the McLaren for fourth. This clash was also investigated, but no action was taken.

With the pack bunched up by the yellow, Vettel found himself back in traffic when he made an early third stop to switch to medium tyres on lap 33.

Button ran three laps longer and extended his lead, with Alonso staying out a further lap still and emerging just ahead of the frustrated Vettel.

The soon-to-be-champion was all over Alonso for a while, until Red Bull suggested now was not the time to take any risks. Alonso then shot off after leader Button, closing to within a second before the McLaren raised its pace in response.

Mark Webber jumped Massa and Hamilton with an early second stop and secured fourth, while having lost out to Massa in the same pit sequence just after their clash, Hamilton overtook the Ferrari again into the first corner on lap 37.

Michael Schumacher took sixth, staying out very late before his third and final stop and therefore leading a grand prix for the first time in his F1 comeback. That strategy also allowed the Mercedes driver to beat Massa to sixth.

Two-stop strategies worked brilliantly for Sergio Perez (Sauber) and Vitaly Petrov (Renault) as they took eighth and ninth. Nico Rosberg charged from the back row to take the final point for Mercedes.

Home hero Kamui Kobayashi's hopes of a great race were ruined by a poor start that left him in traffic all afternoon. He could only finish 13th for Sauber, behind the two Force Indias.

Bruno Senna also lost out on lap one, getting away slightly slowly, then running wide. That and a slow first stop left his Renault only 16th.

The only retirement of the race was Sebastien Buemi, whose Toro Rosso left its first stop with its right front wheel dangling off.
