Welcome to ESPNF1's coverage of the final free practice session for the Abu Dhabi Grand Prix. A final hour to fine tune set-ups ahead of qualifying this evening

After yesterday's running included a soft development compound tyre, today we will be able to see comparable pace on the same rubber, with some low fuel runs likely to point to a potential qualifying order

Don't go thinking that whoever is quickest in this session will be on pole, though, as the track temperature will drop considerably between the end of this session and qualifying as the sun goes down. That can have a large impact on pace

I mention whoever is quickest in this session, it was McLaren smiling at the end of Friday's running after Lewis Hamilton headed a one-two for the team in FP2

And there were also a few problems for the latest two double world champions, with Sebastian Vettel watching on as his Red Bull was craned away after spinning out at turn one:

And while he was there, Fernando Alonso joined him in the turn one barriers:

Expect to see both of those drivers giving the kerb at turn one a wide berth; Felipe Massa was also guilty of taking too much kerb on entry and spinning during FP1, but fortunately for him he stopped before the barriers and the only damage was a set of heavily flat-spotted tyres

Now, if you want to get in touch with us during this hour-long session then you can do so in one of two ways. Either drop us an email using the link above or tweet us @ESPNF1_live. We will try to publish as many of your comments as possible, and answer your questions either on here or on Twitter

Just coming up to 2pm local time, and the air temperature is up at 27C. Track temperature is 41C, but as I said earlier that will drop during qualifying later

Bruno Senna leads out a number of cars as soon as the lights go green

Hamilton sporting some rather strange looking blue and yellow overalls today as part of McLaren's competition to design them for Saturdays. Can't say they quite match the car...

So far nobody has gone on to complete a lap, one installation lap all round with only Hamilton yet to leave the pit lane

Sophisticated car monitoring going on down at Toro Rosso: Buemi's car has the engine cover off and a mechanic is looking in using a torch

Hamilton returns to the pit lane after his installation lap and the track falls quiet again

Mark Webber watches from the entrance to the Red Bull garage as mechanics make changes to his car. He looks very relaxed so I don't think there's a major problem there

D'Ambrosio takes to the track and has the circuit to himself for now. He's trying to make up for lost time after Robert Wickens ran his car in FP1. He carries out an aero test along the main straight between turns 7 and 8

Medium tyres on the Virgin as he starts a flying lap

D'Ambrosio's first lap is a 1:49.573, but that won't be top of the timesheets for very long...

Di Resta starts a lap, also on medium tyres, as Perez goes quickest with a 1:44.566

We're already 15 minutes in to the session, and di Resta has gone quickest with a 1:44.231

Hamilton and Button join the track as Perez improves to a 1:43.905

Renault (OfficialLRGO) on Twitter: "Hot hot hot out there today...no doubt qualifying will be a different kettle of fish"

Looks like trouble for Trulli, as there are a lot of mechanics gathered around the rear of his car in the garage

Massa goes quickest with a 1:43.132, also on medium tyres. We are unlikely to see the soft compound until the final half an hour or 20 minutes of this session

Button now fastest, going almost a second quicker than Massa with a 1:42.163

Bit of an odd moment as Hamilton tries to pass Schumacher up the inside in to turn 11 but Schumacher refuses to give up the corner and cuts the chicane to stay clear ahead

Trulli, Vettel, Alonso and Webber yet to rejoin the track after their installation laps. I mentioned work going on for Webber and Trulli, and Alonso has also been talking to a mechanic about an issue in the cockpit

Vettel is in his car and looks to be preparing to go out on track. Webber is also back in his car too

Bad news for Lotus, as Mike Gascoyne tweets: "Gearbox problem for Jarno, he will not get back out this session"

If that needs changing he will take a five-place grid penalty

Button has improved to a 1:40.993, just 0.193s ahead of Hamilton

Carl emails in to ask: "Rumors about Kimi Raikkonen making a comeback are getting increasingly stronger. He left F1, seemingly bored, when he had a lucrative Ferrari-contract in his pocket all other drivers dreamt about. NASCAR-experimenting, a no-show during a WRC-weekend… How do you rate Raikkonen's motivation and how will this absence affect his performance in this new F1 age, where the competition is stronger than ever?"

I think it could be a case of the grass isn't always greener, and Raikkonen will be motivated to establish himself once again. With his last two teams having been McLaren and Ferrari then if he were to return with Williams you'd think he would be looking to prove himself to then get a potentially championship-winning drive

Vettel goes third, 0.423s slower than Button. Webber is just under a second off the McLaren pace

Webber improves to be just 0.002s slower than Button

Still yet to see a soft tyre run today

Ahmed says: "Alonso says Lewis is the only one who could win a race with a less performing car...Impressive! Considering the amount of love lost over the years."

It's a nice comment Ahmed, and Alonso didn't just say a race, he said Hamilton was the only man who could win a whole championship without having the quickest car. Hamilton said he was "blown away" by those comments

Speaking of Alonso, he has a moment at turn five after getting too much kerb. He has to catch the rear end but runs wide on the outside of six and gets close to the wall

Vettel goes quickest with a 1:40.938, so just 0.057 covers the top three cars right now

Perez is on the soft tyre now, as is Maldonado

Perez goes fifth on softs

Hamilton improves to go quickest with a 1:40.661. He looks very strong on this track

Engine cover off on Petrov's car at Renault, so he's losing time

Massa has reverted to the Singapore-spec front wing after his 'fluttering' problems. With soft tyres he goes quickest bu just 0.030s

Rosberg on softs and he goes third, 0.009s behind Hamilton and 0.039s behind Massa. Hamilton's time set on medium tyres, though

Kobayashi goes 12th on soft tyres; he's been quite quiet so far this weekend after he had a few issues in FP1 which meant he could only complete 18 laps

Not being quiet, however, is Adrian Sutil. He's still unsure of his future at Force India, but he's shown the pace in the car on soft tyres to go quickest with a 1:40.561

Massa quickly ends Sutil's time in the limelight though with a 1:40.183 to go fastest again

Schumacher matches Vettel's lap time to go seventh on the soft tyre

His team-mate Rosberg, however, goes quickest with a 1:40.135

Petrov has managed to get back on track and he goes 13th quickest

Sutil improves once again despite a scruffy final sector. He stays third but less than 0.3s off the pace

Klaas asks: "The future for Jérôme D'Ambrosio isn't looking very bright, I'm afraid. Although he delivered a very decent season so far (given the fact that he has been driving a horrible car) other youngsters with more money are allready waiting to take his place. Will the young Belgian find himself a place in F1 after this season? Are there speculations about his future?"

There certainly is speculation about his future, as Timo Glock is contracted to the team to push it forward, so Virgin (to become Marussia next season) appears to be looking to maximise the money generated from its second seat. Rumours in the paddock suggest Chales Pic could be in the car next season, and while d'Ambrosio has done a good job it must be remembered that he too gained the seat on more than driving skill alone

Rosberg still quickest, but he's back in the garage with the front wing off the car. Webber is now out on track, as is Vettel, but no movement from McLaren yet with seven minutes to go

Webber on his first soft tyre lap, and he's just under 0.2s down through the first two sectors

Hamilton and Button now out on soft tyres too, as is Alonso

Webber improves with the fastest final sector to go quickest with a 1:39.668

Alonso goes second, 0.250s slower than Webber

Vettel now close to Webber's pace, but only goes second. 0.063s slowe than his team-mate

Hamilton a quarter of a second up through the first two sectors

Hamilton goes fastest by almost half a second with a 1:39.177. Button is nearly 0.6s slower in fourth place

Looks like everyone could improve on a second run. Webber still second but within 0.280s of Hamilton now. He came across Vettel in the final sector but didn't lose any time

One lap to cool the tyres and then another lap seems to be the best strategy as Vettel goes second, still 0.226s slower than Hamilton

Hamilton improving on this lap too...

Hamilton does improve again with a 1:38.976, over 0.4s quicker than anyone else

Button goes third, 0.453s slower than Hamilton

Vettel can't improve on his final lap, but Webber does to go third fastest, 0.451s off Hamilton

Hamilton returning to the grid for a practice start, and he tops the timesheets for the second consecutive session. Maybe a touch surprisingly though, he takes up the second grid slot on the grid rather than pole

Just a mention for Barrichello, who only completed five laps in that session. He had an oil leak

Scott emails in: "Hamilton has the bit between his teeth again! Hopefully he can carry this through to the race this time..."

Very closely matched behind Hamilton, with Vettel, Webber and Button split by just 0.026s and Alonso a further 0.2s back, but it's Hamilton who looks mightily impressive around the Yas Marina Circuit. Can he replicate that performance in qualifying? Join us in two hours to find out.
