SINGAPORE, Malaysia - Sebastian Vettel displayed all the guts and determination of a World champion to haul himself back into the Formula 1 title race with a Singapore victory that set up a mouth-watering finale to the season.Vettel kept his focus to win a "killer" 2012 race that ran for a full two hours on September 23 and he cut championship leader Fernando Alonso's advantage to 29 points with six rounds remaining as he seeks a third crown.To say the title showdown has come down to a duel between Vettel's Red Bull and Alonso's Ferrari could be premature given the topsy-turvy nature of this season but while both men have bemoaned a lack of pace, they make up for it in consistency.HAMILTON'S WOESAlonso has spent all season claiming his car was not competitive yet he has forged ahead by picking up big points from average positions on the grid, a feat he repeated in Singapore by finishing third after starting fifth.Alonso told reporters after chasing home Vettel and McLaren's Jenson Button, "On track, we manage to make the most of what we have, making few or no mistakes, thanks to great work from the team. For that alone we deserve to be where we are in the classification."Today we pulled out an advantage over three of our four main competitors."Vettel cut a forlorn figure after an erratic race in Monza ended prematurely with a failed alternator, leaving many observers to doubt whether the German had the desire or the vehicle to mount a serious title challenge. His demeanor changed after a polished drive backed up his domination in practice as both he and Alonso benefited from another failure for Lewis Hamilton, who has offset three wins with three retirements in the last eight races.All season so far McLaren's rivals have claimed the silver car was the most competitive yet Hamilton's challenge took a body blow when he surrendered the lead on the 23rd lap with a gearbox failure and is now 52 points behind Alonso.SUZUKA NEXTRed Bull team principal Christian Horner said: "A tremendous result for Sebastian and the team to win in Singapore. It's a timely win for both championships. It was unfortunate for Lewis to retire from the lead, we know how that feels - nonetheless, Sebastian had tremendous pace all weekend and it's a shame in some respects, as I'm sure they'd have had a great race over the remainder of the Grand Prix."Kimi Raikkonen also lost ground in Singapore as his Lotus proved unresponsive on the tight street circuit with his sixth place dropping him 45 points off the pace as he still searches for a first victory in his comeback season.The teams now head to Suzuka for the Japanese GP on October 7 and while the circuit is a sweeping tribute to near-perfect track design, the title contenders have only one thing on their minds - to finish in the points.Vettel said after collecting his 23rd career victory: "(The championship situation) looks better than before. Fernando finished third and it's 10 points better than before. There are a lot of races left, and it's difficult to predict what is going to happen but we have to make sure we finish the races."The pace is there and even if we are not quick enough to win - we have to make sure we do that. It is a tough championship so far but we are still in it," he said.'SIX TO GO'Ferrari team principal Stefano Domenicali expects the team to make incremental improvements to the car over the final races of the season but ruled out making drastic changes.Domenicali added: "There are six grands prix to go to the end of the season and clearly we need to make a step forward in terms of performance because we can't rely purely on the misfortune of others."Where we need to improve a lot is on circuits that require maximum aerodynamic downforce. Having said that, we mustn't over-react as it's better to bring a few updates that work rather than bringing in too many."
