Hello and welcome to LIVE coverage from the final free practice session ahead of the Abu Dhabi Grand Prix

So that's the end of that - Red Bull lead the way in this session, with Hamilton in third, Alonso in fourth and Button fifth

Vettel again reduces his time yet further to 1:40.696 and it looks like it's going to be a Red Bull one-two in this final practice session

Vettel's team-mate Webber joins him at the top of the sheets with a lap of 1:41.53 with just under five minutes still to go

There's just seven minutes left to go now and still Vettel is unchallenged at the top of the timesheets, having further reduced his lap time to 1:41.142, leading from Alonso and Button, who has just gone 1.41.578

Fernando Alonso and Felipe Massa have just been sent out on to the track on new tyres for a three-lap run at the timesheets

Webber's also out now and starting to post some times but still not getting that close to Vettel, who further extends his lead at the top of the time-sheets with a 1:41.252

There we go, Hamilton is finally out and posts his first flying lap - just shy of Vettel's leading 1:41. 621 that he has just set to further up the ante

Hamilton is still in the garage and doesn't look like he will be out in the next few minutes - he's losing a lot of time as the mechanics rush to get that vibration problem fixed

Vettel goes fastest with his first flying lap of 1:41.721, half a second faster than Fernando Alonso as all the title contenders pour out on to the track for the final half hour of this session

Renault's Robert Kubica reduces the fastest lap time to 1:43.186 with Mercedes Michael Schumacher following round quickly behind to lower things once again to 1:42.518

Just a couple of teams out on the track so far - Sauber, Virgin and Lotus being the only two that have posted flying laps as Timo Glock goes fastest with a lap of one minute and 47.025 seconds

Martin Whitmarsh is having a chat with Jensen Button in the pit lane with the latter still sitting in his car. The McLaren team principle quickly moves across to Lewis Hamilton and has a chat with him too. The tyres have been taken off Hamilton's car by the way

Sebastian Vettel is sat in his car in the pit lane although there is huge amounts of smoke swirling around his lap as the mechanics do some running repairs

Hamilton comes back into the pit lane, swiftly followed by team-mate Jenson Button, as both complain of vibrations in the car. The guys clearly have cold tyres as the mechanics bring out machines that basically look like huge hair-dyers to blow hot air on those front tyres in particular

The session is underway, although it's not greeted by many cars moving out on to the track - the drivers are taking it slowly this morning ahead of what is an incredibly important weekend. It's this to decide this year's world championship
