Red Bull driver Sebastian Vettel recorded yet another start-to-finish win at the Singapore Grand Prix on Sunday to further extend his lead in the Formula One championship.

The German was in a class of his own under the Marina Bay lights, winning by 32.6 seconds over Fernando Alonso and boosting his championship lead on the Ferrari driver from 53 points to 60 with six races remaining.

Lotus’ Kimi Raikkonen was third, ahead of the Mercedes pair Nico Rosberg and Lewis Hamilton.

Starting in pole, Vettel lost the lead at the first corner to Rosberg but took it back as the Mercedes driver ran wide at turn two, and even a safety car period which eroded his early lead could not prevent another Vettel victory.

Neither of Australian duo Mark Webber nor Daniel Ricciardo finished the race.

Ricciardo crashed his Toro Rosso into the barriers which brought out the safety car in the 25th lap, before flames burst out of Webber’s Red Bull car in the final lap.
