Great effort by Rosberg as well - nine hundredths is not even enough time to blink, and he's done a great job to get on the front row of the grid, as has Grosjean with his third place. That's Lotus's best qualification of the season.
A few nervy moments for Vettel after he effectively packed up early to save race tyres - amazing that he took pole with so much in reserve that he was able to put in just one lap in Q3.
SEBASTIAN VETTEL ON POLE FOR THE SINGAPORE GRAND PRIX!
Rosberg comes within 0.091 seconds! So close! And Webber is only third fastest... Yet to come is Hamilton, but he's only fourth fastest - yet moments later Grosjean relegates him to third quickest.
Webber has matched Vettel in the middle sector - Rosberg on a flyer as well and looking very fast...
As the clock ticks down, Mark Webber is out and has posted the fastest first sector - but it's the final sector where Vettel was really picking up time.
Vettel is staying in the car! That saves him a set of supersoft tyres for the race itself, but it also opens him up to a potential upset... though surely only Mark Webber has any hope of pulling it off.
Vettel has just told his put crew on the radio that "I think I can improve by a tenth or two" - so will he bother going out again? Hard to see any reason for him to do so, nobody is anywhere near him at the moment.
The two Ferraris are to get ou under way - but they'll get only one chance at this.
Rosberg second fastest, Webber third, Hamilton fourth... and Hamilton is being told over the pit radio that he's losing 0.2 seconds to Rosberg in the final sector alone.
Surely that'll be enough for Vettel, but we're pretty sure he won't stop there.
Stunning lap from Vettel! It's a 1:42.841, and he's 0.6 seconds faster than anyone else as a pack of cars cross the line. The German is simply untouchable.
Vettel looks good as he gets around the half-way point...
Vettel comes over the line to begin his flying lap - but I can't help thinking all he needs to do is repeat what he did in Q2 and pole will be his.
Fernando Alonso, Jenson Button and Esteban Gutierrez among those in the pits biding their time a bit.
Bit of a different start to this Q3 session! There are six of the 10 cards lined up on the pit lane waiting for the lights to go green as we get under way. Vettel and Webber are the first two of those, clearly keen to get two flying runs in.
Esteban Gutierrez is into Q3 for the first time ever, and he's outqualified team-mate Nico Hulkenberg for the first time as well.
Vettel's 0.8 second margin at the top in Q2 is the biggest of the season so far - almost absurd how much faster he is round this track. That lap he put in looked effortlessly flawless.
Last man over the line is Jenson Button - who clinches the 10th and final spot, right on the edge, with his one and only flying lap of Q2! No such luck for Sergio Perez - Button's team-mate finishes down in 14th.
Raikkonen misses out on Q1! He's 0.070 as he crosses the line... but as a raft of other cars jump into the top 10, he's eventually way out of the picture.
Ricciardo drops a bit in the last two sectors, but he's 7th and appears to have pushed Kimi Raikkonen out of the top 10! Raikkonen is still out though...
Daniel Ricciardo is out and on a flying lap - he's actually quicker than Vettel though the first sector.
Just two minutes left, and Button yet to post a time. Looks like Hamilton has decided not to have a nother lap after all, though.
Vettel crosses the line in 1:42.905! He's almost a second quicker than the field right now... though that margin is trimmed to 0.8 seconds as Webber goes second fastest. Vettel drove a beautiful lap there.
Vettel now half a second faster than anyone else at the second split...
Vettel is out on the track on brand new supersoft tyres - and he's immediately a couple of 10ths faster than Rosberg just to the first split.
Massa's best lap in Q2 so far is a 1.45.1, almost certainly not enough to make Q3 - and indeed even Lewis Hamilton is being told to drive again despite that solid lap.
Sebastian Vettel comes out onto the track now, on soft tyres for the first time in qualifying. Only he, Webber and gambling man Romain Grosjean came through Q1 on mediums alone.
Fernando Alonso posts a lap now, goes third quickest, but is over half a second behind the Mercedes duo right now.
Nico Rosberg comes out and posts a 1:43.892 - Hamilton is almost on his tail and is within three hundredths.
Raikkonen has the fuel for two flying laps - his first is 1:44.794, but he'll go straight into another one so we'll expect him to beat that comfortably.
Raikkonen - who almost pulled out of the weekend due to a back injury - is on a used, scrubbed set of the supersofts. Looks like he's trying to stake a claim early and hope he doesn't need to drive again before Q3.
Fernando Alonso is out on the circuit on the soft tyre, up ahead Kimi Raikkonen is to set the first timed lap of the session, also on the softs.
There's a Lotus and a Williams out on the circuit now, and things are getting busy in the Ferrari garage.
Q2 gets under way - but with the premium on those supersoft tyres, and the track cooling down more and more now that the sun is fully down, expect almost all the drivers to leave it late to have the best chance of making the top 10.
Awful for Paul di Resta as well, he qualified sixth and finished fourth here last year. Not doing his hopes of a good drive next year much good - it's the fifth time in eight races he's failed to progress from Q1.
Massa pulls up to 13th, at the expense of Paul Di Resta - looks like the Scot has missed out on a spot in Q2. That's a massive blunder, while Pastor Maldonado also blunders by finishing 18th. A far cry from his front row spot last year...
Van der Garde does a bit of Playstation driving, clobbering the wall with his rear right tyre. He must have the 'damage' setting turned off.
Dying seconds, and the Red Bulls are more than happy about not having to go out once again.
Felipe Massa currently 18th, he'll have one lap on the soft tyres, and plenty of traffic ahead of him... He needs to nail it.
Plenty of drivers on the faster, softer tyres start flooding round the circuit now and a string of quickest laps sees Lewis Hamilton top of the sheets with a 1:44.196. That's over two seconds a lap quicker for Hamilton on these tyres.
Rosberg clocks a 1:45.208 - he lost a third of a second in the final sector, but is still quicker, just, than Webber.
Rosberg is back out on the track - the computers are claiming that he's still on medium tyres, but his times suggest otherwise - he's over a quarter of a second faster than the Red Bulls.
Vettel crosses the line with a 1:45.755, just three tenths slower than Hulkenberg despite using the far slower tyre. But shortly after him is Mark Webber, who goes fastest of all despite being on the mediums. Back to the pits afer that - he'll be in Q2, no problem.
Vettel is just 0.345 seconds down after two sectors, despite being on the medium tyre....
Almost all the cars back in the pits getting those softer tyres on now - and finally here comes Sebastian Vettel, with the place to himself...
It's a 1:45.381 for Hulkenberg - the supersoft tyre is just a ridiculous amount better than the medium tyre at Singapore. Probably only the Red Bulls that will be able to come through P1 without dipping into their store of supersofts.
Nico Hulkenberg is on a storming lap right now, around a second quicker than Rosberg after two sectors... But that's because he's on the supersoft tyres.
Hamilton loses some time in the final sector, and it's only a 1:46.561 - still second quickest. Neither of the Red Bulls are out yet.
Nico Rosberg is out on the track now as well, and he puts in a 1:46.288 - though Hamilton is on another lap and looks like getting ahead.
Fernando Alonso gets into all sorts of bother on the chicane as he locks up the brakes and ploughs straight through. Whoops! Few scrathes will need fixing on the underside...
1:47.087 from Hamilton - he's on the medium tyre as well. The teams aren't too worried about putting in a few laps on these medium tyres, theyr're not expected to need them in the race.
Lewis Hamilton gets out on to the track for a flying lap - let's see how he'll do... keeping it very neat so far...
Maldonado comes in with a 1:48.458 for his opener - he qualified second here last year, but will have a hell of a job matching that today.
Maldonado is on the first of his timed laps now - getting pretty close to the barriers...
Nico Rosberg has decided to go out now as well - taking advantage of the near-deserted track - and is on the medium tyre.
Pastor Maldonado is out on the track early on - over the radio he's been told to put in three timed laps of the 3.1-mile circuit. Should give us a marker for the session.
P1 begins to... absolutely no fanfare whatsover. Most of the drivers are still mooching around the pits, safe in the knowledge that there are enough fall guys in the F1 field this year that they don't need to get out there and set a string of lap times.
Ferrari's Fernando Alonso has been struggling on this track all weekend, and getting on the front row is widely thought to be be out of the question. Not good news for a driver who is desperately trying to close a 53-point gap on Vettel.
It's 9 o'clock at night in Singapore right now, but it's still over 30 degrees out there, with humdity at 74 per cent. Hot and sticky work for the drivers today.
Lewis Hamilton will have other ideas, however: he had picked up four consecutive poles prior to the Italian Grand Prix at Monza. Not that it helped him much: he's still just one win to his name this season.
After dominating the timesheets in FP2 and FP3, Sebastian Vettel will be hoping to carry his form into the qualifying shootout to earn his second pole in as many races.
