Amongst those at the foot of the timesheet it was Timo Glock who did the best job for Marussia, finishing 19th.
So Vettel had a couple of inconvenient moments but conluded the session on top, as he did in FP1. The German was 0.311s faster than second placed Button, with Alonso, Webber and Hamilton completing the top five.
The sesson ends with Kobayashi spinning across the track and stopping at Turn 19.
Hispania's Narain Karthikeyan gets the full Singapore Sling experience as he bounces along the kerbs.
Despite being pushed back into his garage earlier Kovalainen made it back out for another little run. He's still in 20th place though.
Most of the drivers are on super soft tyres as they conclude their longer runs. We hear Hamilton chatting to his team who ask for two more laps at this pace. The former champion is looking good.
This will be a late night for the drivers as they still have their technical meetings and media commitments to get through and it's nearly 23.00. But many of them stay on European timings to keep their bodies in tune with a normal race day schedule. So they will go to bed late and get up late tomorrow, before returning to action at 18.00 tomorrow for FP3.
Kovalainen is wheeled back into the Caterham garage and that could be goodnight from him.
An error for Perez on the fourth turn sees him lose his line but he avoids a crash. Just.
Not long now for the drivers to make their final checks and gather their last pieces of data for the opening night here in Singapore.
Webber cuts his fourth run short after six laps due to team instructions.
Fun and games through the 'Singapore sling' chicane with Rosberg and Romain Grosjean bouncing around on the kerbs.
It's busy out there at the moment with 21 of the drivers in action under the floodlights.
Caterham are comparing the soft tyres with the super soft option, Heikki Kovalainen running the super softs and Vitaly Petrov going round with the softs. They are 20th and 22nd respectively at present.
Pace man, World Champion and all round winner Vettel is finally back out for a long run with a quarter of an hour to go, so he should have time to register several successive laps.
Räikkönen is the quickest heavy fuel runner at the moment, but Hamilton just told his team he is matching the pace of the Lotus man.
Red Bull are beginning their long runs now, Webber is already on track and Vettel is taking his time to go back out.
Paul Di Resta has had a good session for Force India, he is in sixth place, with a time around a second off Vettel.
Ferrari in particular are stating that they will definitely focus on longer runs for the rest of this practice session at the Marina Bay circuit.
Now we might start to see some longer runs after those fast laps, with P1 having changed hands so many times already in FP2.
Vettel, Button, Alonso and Webber are still the main protagonists, setting their best times with those super soft compounds.
For reference, there is now 1.821 separating 10th placed Romain Grosjean in his Lotus and Vettel in P1.
It looked like Vettel was struggling for a while and Senna's incident interrupted him when he was only a lap into a run. But now he's top of the pile as he registers a P1 time of 1:48.340 to remove any doubts about his pace.
Of course, the remaining races this year take place in Singapore, Japan, South Korea, India, Abu Dhabi, USA and Brazil.
Although Alonso's lead at the head of the championship standings is considerable there is still plenty of racing to be done this year.
Now it's the championship leader in P1 showing how to do it with the super softs, taking P1 by a tight margin - 0.068, before Button grabs the lead from the Spaniard by over two tenths.
We're waiting to see what the likes of Vettel, Webber, Button and Rosberg can do on the super soft tyres.
Hamilton has gone back into the pits to make some changes, still sitting second at present. Maldonado is getting faster and is up to seventh.
Now Schumacher is amongst the pace setters as he moves up into fourth in his Mercedes.
Now Webber is also making great use of those super soft compounds as he registers a 1:48.964 time to go into P1, whilst Kimi Räikkönen has moved up into fifth, 1.381s behind the Australian.
Massa's lead doesn't last long though as Hamilton has super soft tyres on and goes back into P1 with a 1:49.086 lap.
Someone already has gone faster than Hamilton and it is Ferrari's Felipe Massa with a 1:50.039 time.
We're following pace man Hamilton as he returns to action. Can Button, Alonso or Vettel outpace him before the session concludes?
As he headed back out onto the track Rosberg practiced a start at the end of the pits. It's always so exciting to see the force of these F1 beasts.
The green light shows and the session is back underway.
FP2 will resume at 22.13 local time folks.
While we take a break, we have time to remember last year's event. The 2011 qualifying session here saw Vettel take pole ahead of teammate Webber with the McLaren drivers Button and Hamilton in third and fourth respectively. Vettel’s pole time last year by the way was 1:44.381.
The circuit staff bring out a crane to remove Senna's Williams car.
That mishap has cost time for several other men on track as they are forced to stop when on crucial test runs.
We stop temporarily as the marshals are struggling to move Senna's car. There appears to be damage to the rear suspension.
Senna lost his line and clipped a wall, forcing him to abandon his Williams and jog away to safety.
Trouble for Senna at Turn 21, he lost control and is stranded on the middle of the track.
The current top five is Hamilton, Vettel, Alonso, Button and Maldonado, all within 0.8s of each other.
Two of the sports most experienced men Webber and Michael Schumacher are out again for the second runs of this FP2 session.
Alonso goes up to third, 0.66s behind his great rival Hamilton. Senna has finally registered a quick lap and is sitting in 11th place, 1.3s off the pace.
Last year’s race here was won by Vettel, with Button and Mark Webber also on the podium, ahead of Alonso and Hamilton. Expect those guys to be the front runners this weekend too.
We're briefly onboard with Senna as we see him make a mistake in the 'Singapore Sling' section of the circuit. He was all over the place there.
Vettel with a smart new helmet design is lapping quickly, but now Hamilton goes back to the top with a significant 0.423s advantage .
There is little happening on track now, as most of the drivers are back in their garages after those initial runs.
By the way, Sunday’s race begins at 20.00 local time and tomorrow’s Qualifying session gets underway at 21.00 Singapore time.
It is not hindering him too much though as he's just taken P1 with a 1:50.497 lap! Perhaps he just wanted to have a little moan over the radio.
Vettel is telling his Red Bull mechanics that he is having a few problems. He is down in 16th place with his front tyre locking on certain corners.
Next year’s provisional F1 calendar was released earlier today.
Now Button's teammate Lewis Hamilton has shifted him from the top of the timing board, Hamilton going round 0.276s faster than his compatriot.
Title chasing Fernando Alonso is up to fourth with his first fast lap a 1:51.365s effort, still half a second behind leader Button.
The floodlights here at the Marina Bay circuit have been on since before the start of the FP1 run out earlier, although there was still daylight when the action commenced. Now though the floodlights are in full effect and this session will end at 23.00.
Jenson Button has set down a marker and gone into P1 with a 1:50.837 lap, to lead by over half a second.
All the drivers are out on track now, everyone using soft tyres.
Apparently the Mercedes drivers are testing a new exhaust this weekend. Will it help Michael Schumacher and Nico Rosberg pick up the pace?
The first time of the session is set by Perez, a respectable 1:54.830.
The first few minutes see the likes of Sergio Pérez, Pastor Maldonado, Bruno Senna and Charles Pic lapping as the engines begin to roar.
Oh and the track temperature is similar for the moment - 27 degrees Celsius.
The conditions are dry on track, but the air is hot and humid, the temperature does not drop much here at night and it is still 28 degrees Celsius.
The clock ticks over and we're underway, the drivers starting their engines and heading out onto this awesome street circuit.
If you are a quick reader and you missed it earlier you might want to have a look at our report from FP1.
So there is work to do for Alonso if he wishes to maintain or extend his significant championship advantage this weekend.
The German Red Bull driver registered a 1:50.566 lap, putting him 0.049s ahead of his closest rival on this occasion Lewis Hamilton. Over 0.8s behind them Hamilton’s teammate Jenson Button was third and the current championship leader Fernando Alonso was fourth with a similar time to Button’s.
Earlier we saw the drivers get the weekend’s action underway with an FP1 session which commenced on a damp track and ended with dry conditions, the timesheet being headed by World Champion Sebastian Vettel.
The next 90 minute practice gets started at 21.30 in Singapore so the drivers are making their final preparations for action.
Welcome back to our LIVE coverage from the Singapore Grand Prix, where the local time is 21.15 and we’re about to witness the second free practice session.
