Kvyat is out on track after completing just two laps so far. I'm not entirely sure what the problem was but he has yet to set a time.
@Phil,Maidenhead: Only Ferrari has a veto. It will have a place on the F1 Commission like the other teams but not on the Strategy Group.
We're getting close to the time when super-soft tyres are bolted on and drivers go for quick laps. Just Vettel and Sainz out on track at the moment as the other teams fettle their set-ups in the garage.
@Salman: Ferrari. I don't think we saw their true pace during Friday practice as they appeared to focus on race pace over qualifying.
Rosberg is the first to leave the pits on super-softs. He has a 0.307s disadvantage to Hamilton on the softs, will he be able to reverse that on the super-softs?
We should find out quite soon as Hamilton has also left the pits on the super-softs. One of the big challenges here is to stop the rear tyres overheating in the final sector of the lap when the track gets tighter and twistier. Part of that comes down to how they condition them on the outlap and how they use them in the first two sectors.
Rosberg goes faster in the first sector but can only match Hamilton in the second sector...
He goes fastest overall with a 142.196, 0.882s faster than Hamilton, who is not on a particularly fast lap at this stage...
Hamilton does not improve but is now going for his quick lap...
Mistake from Hamilton at Turn 5 again. He runs wide, dirties his tyres and rejoins.
A replay shows Hamilton took way too much kerb in Turn 4 and struggled to slow it enough to make Turn 5 without running wide. Aggressive if nothing else.
So, Hamilton is now on his third lap on these super-softs. Can he finally hook a lap together?
@DonHopings: They used to. Less so, as far as I am aware, with the Pirellis.
@Mary-Lou: The plan is to change that in 2017, but its the engineers who are making the changes...
Hamilton improves to go 0.281s off Rosberg, who just set a 1:41.856 on his second attempt despite a slower first sector time.
Ricciardo is third fastest and 0.870s off Rosberg.
A replay shows that Hamilton came up behind Rosberg during his hot lap and got held up. I doubt much will come of it, but it's worth keeping in mind given the gap between the two.
Vettel is third fastest now on a 1:42.185, 0.329s off Rosberg. Perez is fourth and 0.592s off the pace. An impressive lap from the Force India driver.
Raikkonen is 0.795s off and fifth fastest.
There's the chequered flag. Rosberg finishes the session at the top ahead of Hamilton and Vettel. It's tight, but we didn't see the cleanest of laps from Hamilton in this session. Don't forget that the conditions will be much cooler for qualifying too, so that will change track and car characteristics.
Thanks for joining us. We'll be back for more live commentary ahead of the final qualifying session of the season this evening.
