Vettel takes his second victory of the season after benefitting from a gearbox failure for poleman Hamilton while he was leading the way. The McLaren driver's retirement leaves Vettel out front and despite two Safety Car periods, he is able to stay out front – surviving a scare when he is called before the stewards to explain an incident behind the Safety Car was he was almost struck by Button.
Alonso meanwhile qualifies in fifth place and is able to salvage a podium finish with third, but admits afterwards that Ferrari isn't quick enough and needs to find more speed.
Vettel makes it two wins in a row with a dominant victory at Suzuka – leading from start-to-finish after qualifying on pole position as the title race takes a huge twist.
For Alonso, Suzuka proves to be another race to forget as he qualifies seventh and is then involved in a clash with Kimi Raikkonen on the run to turn one. The end result is a retirement for the championship leader who sees his advantage slashed in the title race.
Vettel makes it three wins in a row with another comfortable win, despite missing out on pole position to team-mate Webber on Saturday in Korea. Beating the Australian off the line, Vettel stays out front to the finish for a victory that puts him ahead of Alonso in the points for the first time since Bahrain.
Alonso manages to qualify in fourth but come race day, he has no answer to the pace of Red Bull. Although he gets up to third on the first lap, he is unable to challenge he pair ahead and finishes on the bottom step of the podium.
Vettel's domination of the latter part of the season continues as he again takes pole position and the follows it up with a fourth successive victory that enables him to extend his advantage in the standings. No-one can get close to the German despite the appearance of sparks coming from underneath his car late on; something Red Bull says afterwards was no cause for concern.
Alonso qualifies in fifth spot and battles ahead of the McLarens of Hamilton and Button early on before hunting down Webber when he suffers a KERS failure – enabling the Spaniard to mimimise his losses to Vettel in the title race.
Raikkonen wins for the first time since his comeback as Vettel's winning run comes to an end. The German qualifies third but is then demoted to the back of the grid after stopping on his in-lap, with the FIA unable to take a fuel sample from the Red Bull after the session. However, an astonishing comeback driver sees the defending champion recover to finish on the podium in third place.
Alonso starts from sixth place but is soon making forward progress and works his way up to second place. A late Safety Car period allows him to close up on Raikkonen but the Spaniard can't make a move for victory and has to settle for a finish just one place ahead of his title rival.
