Sebastian Vettel leads from start to finish in Singapore, while team-mate Mark Webber suffers from engine problems
Sebastian Vettel won the Singapore Grand Prix, further extending his lead in the 2013 Formula One World Championship.
The Red Bull driver beat second placed Fernando Alonso (Ferrari) by 32 seconds, with Kimi Raikkonen taking third position for Lotus in the 61-lap race.
Vettel qualified on pole position for the start of the race, followed by Nico Rosberg (Mercedes) and Romain Grosjean (Lotus). His Red Bull team-mate Mark Webber qualified in fourth position.
After a clean start to the race, Rosberg challenged Vettel into the first corner, causing the reigning world champion to briefly lose the lead. Rosberg, though, immediately ran wide, putting Vettel back in to a lead he was never to lose. Alonso enjoyed a flying start to move from seventh to third position.
As the race entered its middle stages most teams suffered with excessive tyre degradation, and many were forced to reconsider their original two-stop strategies.
Daniel Ricciardo (Torro Rosso) retired from the race after putting his car into the barriers on lap 25, causing a safety car period. He was followed by another retirement from Paul Di Resta (Force India), who crashed into the barriers at turn seven on lap 55.
McLaren's Jenson Button suffered from a number of tyre problems during the race, falling from third position to seventh within a matter of laps towards the end, having previously worked his way through the field with some canny tyre and safety car tactics.
Webber suffered a repeat of the enigne and gearbox problems he endured at Monza, and was told by Red Bull to short shift his gearchanges. During the final laps a radio message from Red Bull was heard to say "this is about getting the car to the finish, now".
His situation continued to worsen, however, and following a car fire on the final lap he was unable to finish the race.
Speaking on the podium Vettel said: "We had some very good pace. The car was a very good asset to the team, it was a pleasure to drive it around this track."
The next race in the Formula One calendar is due to take place in Korea on 6 October.
