Follow live coverage of the Singapore Grand Prix from the Marina Bay Circuit with F1i.
After an exciting qualifying session, an intriguing race is in store with Mercedes not starting as favourites for the first time since the new regulations were brought in. Sebastian Vettel starts from pole position but will face stern opposition from Daniel Ricciardo - starting second - and Daniil Kvyat - fourth - as Red Bull showed impressive long run pace on Friday.
Mercedes' Lewis Hamilton and Nico Rosberg can only start from fifth and sixth places respectively after being a massive 1.5 seconds off the pace in qualifying. Toto Wolff says there is little chance of a turnaround on Sunday, with the defending champions struggling for grip all weekend.
The Singapore Grand Prix is one of the most spectacular races of the season, with the race taking place under floodlights around the city streets. Pole position is crucial, with five of the last seven races having been won from pole. Vettel is going in search of his third win in the season, while Ricciardo has not won since Belgium last year.
Williams is looking to capitalise on Mercedes' woes with Valtteri Bottas lining up right behind Hamilton and Rosberg. Further down the grid, McLaren goes in search of its first points since Hungary with Fernando Alonso starting from 12th place on a circuit more suited to the MP4-30. It is part of a tight midfield pack also featuring Force India, Lotus and Toro Rosso.
Alexander Rossi will start last on his Formula One debut, with both Manor drivers having taken new gearboxes ahead of the race.
