Championship contender Lewis Hamilton achieved his 36th career pole position at Marina Bay, Singapore by beating his Mercedes team-mate by seven thousandths of a second.
Hamilton was only sixth quickest on his first run in the Q3 top ten shootout but despite a lock-up at Turn 1 on his final lap, a particularly strong run through the middle part of the lap allowed him to beat Rosberg by a tiny margin.
Red Bull Racing locked out the second row, with Daniel Ricciardo again out-qualifying his world champion colleague of Sebastian Vettel. The difference was only half-a-tenth.
Fernando Alonso was fifth fastest, only a tenth behind the leading Red Bull, although Ferrari team-mate Kimi Raikkonen was not able to do better than seventh after suffering a power problem on his second run.
In between the Scuderia is Felipe Massa. The Williams driver putting in an impressive lap to go provisional pole on the first-run times, but was only able to make a tiny improvement on his second lap.
Williams team-mate Valtteri Bottas was eighth and was unable to improve on his second run.
Kevin Magnussen was ninth for McLaren, only 0.569 seconds off Hamilton’s pole position time, while Daniil Kvyat was slowest in Q3 after having only one set on super-soft rubber available for the final qualifying session.
Jenson Button and Jean-Eric Vergne were in the top ten in Q2 on their first runs, but with both Williams drivers setting slow times after choosing to run used super-softs for their first run, were always in danger of missing the cut.
They were bumped down to P11 and P12 when Massa and Bottas improved on a fresh set of Pirellis.
Button was able to improve on his second run, but a lock-up at the hairpin cost him time and he missed the cut by 23 thousandths of a second, ending up P11.
Vergne was unable to improve on his second run, complaining about front-end grip and suffering a costly lock-up, meaning he qualified P12.
The Force India pairing of Nico Hulkenberg and Sergio Perez also both failed to improve on their second runs, ending up P13 and P15 respectively.
They were split by Esteban Gutierrez, showing a strong turn of pace in the upgraded Sauber.
Romain Grosjean was slowest of those who made it to Q2 and was very vocal on the team radio about an engine problem that cost him time.
Adrian Sutil came close to escaping Q1, but failed to relegate Perez into the dropzone with his final lap in Q1 and ended up P17.
Pastor Maldonado blamed a power unit problem on his final run for failing to reach Q2.
He was unable to fully recharge the battery, meaning he was lacking full power on his final lap, ending up P18, behind Jules Bianchi.
The Marussia driver put in a superb lap on his final effort to jump ahead of his team-mate Max Chilton, who ended up P21, with Caterham’s Kamui Kobayashi doing a good job to separate the pair.
Marcus Ericsson joined the session late after the Caterham team had to work flat out to solve an electrical problem that had struck in free practice, ending up last.
So an extremely close qualifying session with the top seven covered by less than half-a-second. It was another Mercedes front-row but Red Bull and Ferrari are not far behind.
