Cue jokes about the grapes being sour...
@knightofAMG: Yes, Toro Rosso looks to be following Red Bull's old example on that one.
Interesting from Massa, who can only go 11th. he's over a second down on team-mate Bottas. But he's only been in the top ten of a Friday session once this year.
Button having to come off line coming through the final chicane, with a slowing Mercedes in front of him.
Great on board being shown of Bottas coming through 130R. Looks like he took it flat, too.
Verstappen is back out on track. Interesting, on the tower in the pit lane his three-letter name is VES, not VER - which of course is used for the man he is replacing, Vergne.
Doesn't MAX work fine...?
Verstappen is currently four tenths off team-mate Kvyat, with 16 laps under his belt.
Great minds, Dogue. Great minds.
@PA: Max could be $$$ perhaps
Or £££, for my fellow Brits here.
Longer runs currently underway. Bottas' last a 37.727. Ricciardo's a 37.904 - the Williams/Red Bull comparison is the one I'm most interested in this weekend, to be honest.
@HiranRajapaksha: Alonso's comments have become more cryptic with every race. Yesterday being a prime example. He had the chance to refute the rumours once and for all, but he refused to. Clearly, talks are ongoing with Alonso and Ferrari, meaning he's still not committed his future there yet. For me, the move to McLaren could be too risky but then it could be a masterstroke. Then again, leave Ferrari and it could produce a title-winning car next season. I'd stay put, personally. But that's just me.
Appears I was wrong earlier when I said Kobayashi was taking part in today's session, when in fact Merhi has replaced Kobayashi for this session. Apologies.
Problems at Marussia, it seems, with Bianchi and Chilton combined only having 14 laps to their name.
Hulkenberg the latest to run wide at Degner. At the last corner lap he had a twitch coming through the Spoon.
@RohanMehta: True, but that was 2007. I think Alonso and, most importantly, Ron Dennis consider that water under the bridge now.
Less than 19 minutes left in that session.
Rosberg ventures out on track again.
Worth remembering everyone is on hard (prime) compound tyres in this session. Won't see the option until the second session of todday.
@HiranRajapaksha: Cutting the gap to Mercedes over the winter will be a big ask, not just for Ferrari but Renault as well. Next year's car will be James Allison's first since joining the team, or at least that he's had complete control over. That could give Alonso a car he can win with - and we all know Alonso doesn't need the best car to win races.
Hulkenberg's struggles continue as Perez jumps ahead of him by two tenths with his final run.
Hamilton is out on track too.
@PA: I doubt it, it would be a wasted set JEV could use later.
@Sundar: I think Alonso has proved that in his career. 2012 being a prime example, when he nearly won a championship with a below-par car. This year he has driven the Ferrari above its capabilities, too.
@mfbull: They have "tokens" they can use over the winter to change a certain amount of engine parts. They can choose to use those tokens on certain parts, and then that's it. So it's how efficiently they use those changes that will define that, I guess.
The Mercedes lap times suggest they have gone out on a high-fuel run.
Lots of sparks from under Vettel's car.
