Vettel seals historic F1 world title defence

Germany's Sebastian Vettel became Formula One's youngest back-to-back world champion on Sunday when he finished third in the Japanese Grand Prix behind Jenson Button and Fernando Alonso. The Red Bull driver, 24, who needed just one point to clinch the title, joins Juan Manuel Fangio, Ayrton Senna and Michael Schumacher as one of only nine drivers to successfully defend the title. He ran down the pit lane to celebrate with his mechanics after the race, which sealed the championship with four grands prix remaining following a dominant season with nine wins in 15 outings. "Life for me, and I think all the drivers, doesn't get much better than this. Sunny days, a lot of fans, everyone excited to see what you do. I think that is what life is about," an emotional Australian Mark Webber was fourth for Red Bull, eight seconds adrift of Button, while Briton Lewis Hamilton of McLaren had another controversial race, clashing again with Felipe Massa of Ferrari en route to finishing fifth. Schumacher was sixth for Mercedes, briefly leading the race after the final round of pit stops, while Massa was seventh. Mexican Sergio Perez came through from 17th on the grid to take eighth for Sauber with a two-stop strategy, while German Nico Rosberg drove his Mercedes from second-last on the grid to finish 10th. Vettel didn’t lead last year’s world championship until after the final race in Abu Dhabi, but this season he has never been headed in the standings. However Button, who took his fifth win for McLaren and his first in dry conditions since joining the team, said the victory showed Vettel's competitors were closing the gap on dominant Red Bull. "This circuit is very special to all of us, so to get a victory here in front of this Japanese crowd means a lot," Button said. "This gives us a lot of motivation. To see three cars within a few seconds (at the finish) shows how competitive F1 is right now." He said it was "very emotional" to win on what was a "fast and flowing" circuit, and added that the feeling was almost like winning his first home Grand Prix. Button needed to win the final five races of the season and have Vettel not score a point to extend the championship to next weekend’s race in South Korea, and he made a strong start, shaping up to pass Vettel into the first corner. But the German defended robustly, prompting Button to tell his McLaren team over the radio that "he’s got to get a penalty for that". But stewards decided to take no further action. Vettel led the race through the first set of pit stops, but after re-passing Hamilton on lap eight, Button narrowed the gap and finally passed the German as he returned to the track following his tyre-change on lap 21. On the next lap, Hamilton and Massa clashed at the final chicane, with a piece of front wing from Massa’s car left in the middle of the circuit, prompting a three-lap safety car period to remove the debris. The incident was investigated, but no action was taken. The clash follows a series of bad-tempered incidents this year between the pair, with Hamilton running into the back of Massa in the most recent race in Singapore. An angry Massa called for the FIA, the sport's governing body, to be tougher on Hamilton in future races. "For what he says, I don't care. He doesn't learn. I race against him, against whatever driver in the same way. He has already passed the time to speak, which I tried and he didn't," Massa said. But Hamilton downplayed the incident, blaming a lack of visibility. "I don't really know what happened with Felipe - I had no idea he was there. I have no problems with him," he said. "I want to apologise for our cars touching, but fortunately nothing happened to either of us." Button took control of the race after the lap 28 re-start, setting a new fastest lap on three successive circuits as he extended his margin to 2.5secs. He briefly relinquished the lead to Schumacher as the German waited until lap 41 until making his final stop for tyres, and then maintained a gap of more than a second despite Alonso closing rapidly in the final laps. Button set the fastest lap of the race, 1:36.568, on the 52nd of 53 laps to underline the pace he had in reserve as McLaren celebrated their fifth win of the year. Alonso used his own final stop to leap past Vettel. With four races left in the season, Vettel has 324 points, with Button’s victory keeping the Briton in second place in the championship with 210. Alonso retains third on 202, while Webber stays fourth with 194.
