As the teams returned to Asia, the focus shifted to the championship race. Lewis Hamilton put himself in the ideal position to take the fight to Fernando Alonso, qualifying on pole whilst Alonso could only manage fifth place. In the physically most demanding race of the year, the teams jostled for position through the first phase of the Grand Prix, trying to position themselves for the final ten laps. Just as the drivers established a rhythm, Hamilton's gearbox failed, forcing him out of the race and handing the lead to Sebastian Vettel. The race was shortened by two laps to fit the two-hour time limit for a Grand Prix following a pair of lengthy safety car interventions; first, Narain Karthikeyan understeered into the barriers under the grandstands on lap 30, forcing the safety car to be deployed. The drivers had little opportunity to get comfortable on the restart, as Michael Schumacher misjudged his braking point at the end of the Esplanade Bridge, careening into the back of Jean-Éric Vergne and triggering the safety car for the second time in an accident that was a near mirror-image of his collision with Sergio Pérez in 2011. He was later given a ten-place grid penalty for the Japanese Grand Prix. Vettel controlled the race from the second restart, beating Jenson Button to the line, for his second win of the season and his first since the Bahrain Grand Prix five months previously. Alonso completed the podium, retaining his championship lead after defending from Paul di Resta late in the race. Elsewhere, a string of retirements – including a late engine problem for Bruno Senna, which left the Brazilian with minor burns to his back – and a series of altercations involving Mark Webber, Nico Hülkenberg, Kamui Kobayashi and Sergio Pérez as they fought over the minor points positions allowed Timo Glock to finish twelfth, the result seeing Marussia retake tenth position in the World Constructors' Championship from Caterham.
