That's all from us today, but what a race we have in prospect tomorrow. Will it be Ferrari or will it be Red Bull who take victory?
Can Lewis Hamilton or Nico Rosberg battle through from an unfamiliar position to win, or could there be another Singapore surprise in store?

Kvyat's warning
A warning from Daniil Kvyat, who will line up a career-best fourth on the grid tomorrow: "As the lights go off we will try and overtake the Ferraris."
Speaking of starts, that has been Mercedes Achilles heel in recent races. A busy night ahead for the team to try and make sure they don't lose any valuable time off the line tomorrow.

Fernando Alonso's 12th place equals McLaren's best performance in Q2 this season, with Jenson Button having also secured 12th in Monaco. He's finished inside the points at every single Singapore GP, and you;d fancy his chances of continuing that tomorrow.
Fifth will be a tough place to fight for a 41st grand prix win from Lewis Hamilton but, regardless of the result, he says he enjoyed the qualifying session.
“It was a good qualifying and I enjoyed it, but I was on a knife edge to get as much as I could," he said. "Our problem this weekend is tyres, they are not giving us a lot of grip and we slide around a lot.
“We try to understand why our tyres are bad. We have the quickest car but cannot utilise it with the tyres.”

Long runs brought to an end
That qualifying result has brought to an end a run of Mercedes dominance in a number of areas.
Their pole streak ends at 23, one shy of the record set by Williams across 1992 and 1993 (pictured), while Lewis Hamilton's consecutive front-row start streak ends at 20.
Hamilton's consecutive run of poles also ends at seven, one short of the all-time record set by Ayrton Senna.

Speaking of Fernando Alonso, he loves a bit of Singapore. He has finished in the points in all seven previous races, climbing the podium in five of those.
He was seventh fastest in final practice earlier today, just 0.014s slower than the best effort from Nico Rosberg, who was P7.
From the archives

Pretty much synonymous with the Singapore Grand Prix is the controversy that surrounded its inaugural race back in 2008.
A Nelson Piquet Jr crash early on brought out the safety car, allowing Fernando Alonso, who had started 15th and pitted early, to gain time on the rest of the field.
Once the race restarted Alonso was fifth and eventually worked his way up into first place, where he stayed for the remainder of the race.

Pacesetting Singapore
BBCCopyright: BBC
Ferrari and Red Bull are not the only ones who are showing pace in Singapore, with the local population the fastest walkers in the world.
There's plenty more interesting and quirky stats in our Singapore GP preview feature.
“There have been some tweaks to the Marina Bay track this year, with Turns 11 and 12 eased and the route over the famous Anderson Bridge tweaked in the hope of creating an overtaking opportunity into the previously very tight Turn 13 after the bridge. but they have not met with universal approval from the drivers.
"Fernando Alonso was quite positive, saying ‘it should be safer’ and feeling that overtaking would be easier, with different lines possible into Turn 13. And as no-one is better at overtaking than him, it’s worth listening.
"However, Lewis Hamilton said he ‘didn’t like’ the modifications, and Jenson Button agreed. ‘I don’t think it will make much difference tho overtaking,’ Button said, ‘and the bit before the bridge where it is just a concrete barrier, I’m sure there is more of an angle than it looks but it looks like the barrier is straight ahead of you. Last year it was more of an adrenaline rush, narrower, but still felt good, felt right, whereas now it doesn’t feel quite right.’”

Hamilton's task

Lewis Hamilton can write his name in the history books (again) this weekend because victory would draw him level with Ayrton Senna on 41 wins from 161 races.
There's just the small matter of qualifying to get through first though. Just how important is pole position for Hamilton?
"You can't overtake here," he said on Friday.
Pretty important then.

Right then, this qualifying session is possibly the hardest one of the season to predict. How do you see it going? Could we be on for a Ferrari or a Red Bull on pole, or do you fancy Mercedes to pull it out of the bag?
Let us know via #bbcf1, text in on 81111 (UK only) and have your say on the BBC Sport Facebook page.
“What is going on with Mercedes? That is the big question heading into qualifying.
"Is their apparent lack of pace an elaborate bluff and they will, as Daniel Ricciardo said on Friday, make ‘fools’ of everyone when it matters? If so, it doesn’t look like it at the moment. If it is not a bluff, what’s wrong?
"The drivers are complaining of a lack of grip and traction. But why? There have been murmurings about the raised minimum tyre pressures this weekend, but other teams have rejected that as a cause. Whatever it is, it seems inconceivable that the team can have lost 1.5 seconds a lap on their rivals in the space of 10 days.”

Hello! Welcome to our coverage of qualifying for theSingapore Grand Prixand, I don't know about you, but I'm really looking forward to this one!
Sebastian Vettel finished fastest in final practice, with his Ferrari team-mate Kimi Raikkonen second.
But it was the performance of the Mercedes that was really interesting as Lewis Hamilton was more than a second slower than Vettel while Nico Rosberg finished up only a smidge faster than Fernando Alonso.
It may 'only' have been practice, but it certainly sets things up for a fascinating session of qualifying.
Upset on the cards?

Throughout this season, Mercedes have largely swept aside all before them. Whenever there has been a hint of a potential challenge to their dominance, they quickly put it to bed.
However, something in Singapore seems a little different. For the first time in a long while, they genuinely seem a little flustered.
Could we be on course for a season first, with a car other than a Mercedes on pole?

A challenge Mercedes want and it is a challenge it looks like they are going to get. Will they turn it up for qualifying?

“‘It’s only Friday,’ is the usual mantra from drivers and teams when confronted by media asking them about lap times in first and second practice, and of course they have a point.
"That said, the times set in the race-simulation runs do quite often give a good indication of how the weekend is going - Ferrari technical director James Allison even admitted it after Sebastian Vettel’s first victory of the year in Malaysia back in March. And on Friday, those times were very interesting indeed - and they confirmed the impression that Mercedes have some work to do.
"Engine turned down or not, for Lewis Hamilton to be an average of 0.445secs down on Vettel, 0.314secs off Daniil Kvyat and 0.159secs from Daniel Ricciardo did suggest something was wrong. Nico Rosberg was in even more trouble - 1.1secs slower than Hamilton on average.”

The world ain't all sunshine and rainbows
Mercedes are starting to sound a lot like Sylvester Stallone in Rocky Balboa in these tweets.
They are not at washed up boxer on the comeback trail stage, but a fight back for victory in Sunday's race will be up there with Rocky beating Ivan Drago in my books.

Kvyat's warning
A warning from Daniil Kvyat, who will line up a career-best fourth on the grid tomorrow: "As the lights go off we will try and overtake the Ferraris."
Speaking of starts, that has been Mercedes Achilles heel in recent races. A busy night ahead for the team to try and make sure they don't lose any valuable time off the line tomorrow.
Post update
Fernando Alonso's 12th place equals McLaren's best performance in Q2 this season, with Jenson Button having also secured 12th in Monaco. He's finished inside the points at every single Singapore GP, and you;d fancy his chances of continuing that tomorrow.

We'll go for it - Rosberg
Nico Rosberg, who qualified sixth: “It’s disappointing. We tried everything but did not make progress. Those in front are so fast and phenomenal.
"I lacked a lot of grip. Why, I don’t know. We will go for it tomorrow, but we think it will be tough for sure tomorrow.”

Hamilton 'on a knife edge'
Fifth will be a tough place to fight for a 41st grand prix win from Lewis Hamilton but, regardless of the result, he says he enjoyed the qualifying session.
“It was a good qualifying and I enjoyed it, but I was on a knife edge to get as much as I could," he said. "Our problem this weekend is tyres, they are not giving us a lot of grip and we slide around a lot.
“We try to understand why our tyres are bad. We have the quickest car but cannot utilise it with the tyres.”
Post update
Long runs brought to an end
That qualifying result has brought to an end a run of Mercedes dominance in a number of areas.
Their pole streak ends at 23, one shy of the record set by Williams across 1992 and 1993 (pictured), while Lewis Hamilton's consecutive front-row start streak ends at 20.
Hamilton's consecutive run of poles also ends at seven, one short of the all-time record set by Ayrton Senna.

Speaking of Fernando Alonso, he loves a bit of Singapore. He has finished in the points in all seven previous races, climbing the podium in five of those.
He was seventh fastest in final practice earlier today, just 0.014s slower than the best effort from Nico Rosberg, who was P7.
From the archives
Pretty much synonymous with the Singapore Grand Prix is the controversy that surrounded its inaugural race back in 2008.
A Nelson Piquet Jr crash early on brought out the safety car, allowing Fernando Alonso, who had started 15th and pitted early, to gain time on the rest of the field.
Once the race restarted Alonso was fifth and eventually worked his way up into first place, where he stayed for the remainder of the race.

Pacesetting Singapore
Ferrari and Red Bull are not the only ones who are showing pace in Singapore, with the local population the fastest walkers in the world.
There's plenty more interesting and quirky stats in our Singapore GP preview feature.
Hamilton 'doesn't like' Singapore changes
Andrew Benson
Chief F1 writer
“There have been some tweaks to the Marina Bay track this year, with Turns 11 and 12 eased and the route over the famous Anderson Bridge tweaked in the hope of creating an overtaking opportunity into the previously very tight Turn 13 after the bridge. but they have not met with universal approval from the drivers.
"Fernando Alonso was quite positive, saying ‘it should be safer’ and feeling that overtaking would be easier, with different lines possible into Turn 13. And as no-one is better at overtaking than him, it’s worth listening.
"However, Lewis Hamilton said he ‘didn’t like’ the modifications, and Jenson Button agreed. ‘I don’t think it will make much difference tho overtaking,’ Button said, ‘and the bit before the bridge where it is just a concrete barrier, I’m sure there is more of an angle than it looks but it looks like the barrier is straight ahead of you. Last year it was more of an adrenaline rush, narrower, but still felt good, felt right, whereas now it doesn’t feel quite right.’”

Hamilton's task
Lewis Hamilton can write his name in the history books (again) this weekend because victory would draw him level with Ayrton Senna on 41 wins from 161 races.
There's just the small matter of qualifying to get through first though. Just how important is pole position for Hamilton?
"You can't overtake here," he said on Friday.
Pretty important then.

Mercedes making 'fools' of everyone?
Andrew Benson
Chief F1 writer
“What is going on with Mercedes? That is the big question heading into qualifying.
"Is their apparent lack of pace an elaborate bluff and they will, as Daniel Ricciardo said on Friday, make ‘fools’ of everyone when it matters? If so, it doesn’t look like it at the moment. If it is not a bluff, what’s wrong?
"The drivers are complaining of a lack of grip and traction. But why? There have been murmurings about the raised minimum tyre pressures this weekend, but other teams have rejected that as a cause. Whatever it is, it seems inconceivable that the team can have lost 1.5 seconds a lap on their rivals in the space of 10 days.”

Hello! Welcome to our coverage of qualifying for theSingapore Grand Prixand, I don't know about you, but I'm really looking forward to this one!
Sebastian Vettel finished fastest in final practice, with his Ferrari team-mate Kimi Raikkonen second.
But it was the performance of the Mercedes that was really interesting as Lewis Hamilton was more than a second slower than Vettel while Nico Rosberg finished up only a smidge faster than Fernando Alonso.
It may 'only' have been practice, but it certainly sets things up for a fascinating session of qualifying.
Upset on the cards?
Throughout this season, Mercedes have largely swept aside all before them. Whenever there has been a hint of a potential challenge to their dominance, they quickly put it to bed.
However, something in Singapore seems a little different. For the first time in a long while, they genuinely seem a little flustered.
Could we be on course for a season first, with a car other than a Mercedes on pole?
Post update
A challenge Mercedes want and it is a challenge it looks like they are going to get. Will they turn it up for qualifying?
We are going to take a short break. You can read Andrew Benson's FP3 report in the interim and join us at 13:00 BST for build-up to what could be a very intriguing qualifying session indeed.

Thoughts on Friday
Andrew Benson
Chief F1 writer
“‘It’s only Friday,’ is the usual mantra from drivers and teams when confronted by media asking them about lap times in first and second practice, and of course they have a point.
"That said, the times set in the race-simulation runs do quite often give a good indication of how the weekend is going - Ferrari technical director James Allison even admitted it after Sebastian Vettel’s first victory of the year in Malaysia back in March. And on Friday, those times were very interesting indeed - and they confirmed the impression that Mercedes have some work to do.
"Engine turned down or not, for Lewis Hamilton to be an average of 0.445secs down on Vettel, 0.314secs off Daniil Kvyat and 0.159secs from Daniel Ricciardo did suggest something was wrong. Nico Rosberg was in even more trouble - 1.1secs slower than Hamilton on average.”

Singapore is, of course, a night race, and as a result many people working at the race tend to keep their body clocks on European times. Breakfast at 3pm anyone? (Quite normal for students to be fair).
