SUZUKA, Japan - Red Bull's Sebastian Vettel won the 2013 Japanese Grand Prix on Sunday but was made to wait for his fourth successive Formula One title after Ferrari's Fernando Alonso finished fourth.The 26-year-old German's fourth win at Suzuka in the last five years left him with a lead of 90 points over Alonso with four races, and a maximum 100 points, remaining. The next race is in India on October 27.BATTLE ON TRACKVettel's Australian team mate Mark Webber, who had started on pole, finished 7.1 seconds behind in a Red Bull one-two with Frenchman Romain Grosjean taking third place for Lotus on a sunny afternoon at the Honda-owned track.Vettel shouted over the team radio "Ichiban (first), Ichiban," whooping in delight after taking the chequered flag at the end of a race that hinged on his ability to do two stops to Webber's three.He said: "Great job, thanks a lot for bringing the car back, unbelievable. You're the best team in the world. Thank you very much boys, I love you."It was Vettel's fifth win in a row, ninth in 15 races this season and 35th of his career.Asked on the podium about the championship, with the passionate crowd roaring in approval, he added: "Obviously we have a very good gap but we still keep pushing... it looks very good at this stage but it's not over until its over."Alonso, who became Formula One's leading all-time points scorer, had no illusions about his chances."Even if Vettel doesn't finish all of the races I need to win nearly all (of them), so it's a matter of time," said the Spaniard.STORMING STARTWebber always knew he was going to have a battle on his hands with his team mate but it was Grosjean who seized the lead with a storming start from fourth while both Red Bull drivers were slow to react.Vettel made contact with Lewis Hamilton's Mercedes, with the Briton first suffering a puncture that sent him to the back of the field and then retiring. Hamilton said: "The floor was destroyed... I was a second and a half to two seconds off the pace and the car was pulling to the right. It's a good job they pulled me in."The Red Bull emerged unscathed, with the team reassuring a concerned Vettel, and the German settled into third place at the end of the opening lap.A beaming Vettel, who took the lead for the first time on lap 13 after Grosjean and Webber had pitted, said: "A horrible start and then a fantastic comeback." The lead changed between the three over the race according to pitstops with Webber making his final stop 11 laps before the finish. The Australian had hoped to claw back the deficit but could not get past Grosjean until the penultimate lap, by which time Vettel was nine seconds clear and out of reach.Red Bull principal Christian Horner said: "Mark was going through the tyres a bit quicker and getting into trouble earlier. It made a huge amount of pressure on the two-stop and would have been very difficult to beat Grosjean so we switched from two to three."Unfortunately we lost too much time at the end there behind Grosjean for him to have a crack at Sebastian but he (Vettel) just made the tyres last extremely well."Kimi Raikkonen was fifth for Lotus with Nico Hulkenberg sixth in the Sauber. His team mate Esteban Gutierrez became the first rookie driver to score a point this season with seventh place for Sauber.Nico Rosberg put some points on the board for Mercedes, who slipped further behind Ferrari in third place in the championship, with Britain's Jenson Button ninth for McLaren. Ferrari's Felipe Massa was 10th. Stay with Wheels24 for the 2013 F1 season – fresh reports every day.
