    Lewis Hamilton

    Lewis Hamilton seized the advantage on Friday afternoon, as he has done in the last few races, finishing a massive eight tenths clear of the field.

    That's not representative of the gap to team-mate Nico Rosberg, who made a mistake on his final flying lap, but will no doubt give him confidence ahead of qualifying tomorrow.

    Can Rosberg respond on Saturday? I'll see you then to find out.

  2. Post update

    So that's it for track action today. Final practice starts at 09:00 BST, with the live text resuming at 08:30. Qualifying follows at 12:00.

    Christian Horner looks ok

    "We'd expect to be up with McLaren, Williams and Ferrari" says Red Bull boss Christian Horner, whose drivers Sebastian Vettel and Daniel Ricciardo finished ninth and 13th fastest respectively.

    "The drivers are not saying there's anything particularly wrong with the car, but it doesn't seem quite quick enough."

  6. Post update

    It's all very close between Kevin Magnussen in second and Felipe Massa in seventh. They are separated by just a quarter of a second.

    Lewis Hamilton, though, is way out in front with a lead over eight tenths of a second.

  7. Post update

    BBC F1's Tom Clarkson reports that Pirelli engineers were very quick to cover up a tyre taken off Jenson Button's car, where a flatspot had worn it down to its canvas.

    Lewis Hamilton finishes quickest in second practice for the Russian Grand Prix.

  10. Post update

    The track is pretty busy, with 14 cars out on track. It'll be enough for a timed lap and also give the drivers an opportunity to do a practice start.

  11. Go! Go! Go!

    We're back under way, with three minutes of the session still to go.

  12. Post update

    When BBC F1 commentator Ben Edwards asks Red Bull boss Christian Horner what they think the problem is on Daniel Ricciardo's car, he replies: "I'll give you three guesses, no, one guess." Ben replies: "Power unit failure?"

    "Yes," says Horner, "In fairness, that power unit was right at the end of it's life. Unfortunately, it's missed six and half minutes of use."

    Red Bull have had a number of problems with the Renault power unit this season.

  13. Red flag

    Jenson Button

    Jenson Button locks up and runs wide. The 2009 world champion reports a flat-spot and is then told to pit at the end of his lap.

  17. Post update

    McLaren's Jenson Button is told that his pace on the long run is good. He's in the 1m44s. His engineer asks how his tyres are performing. "OK," comes the response. Short and to the point.

  18. Post update

    Fernando Alonso

    Having said the order is unlikely to change, Fernando Alonso is clearly on a different programme as he's just gone third quickest with a 1:40.504, just over eight tenths off the pace.

  19. Post update

    Here's how they stand with 20 minutes remaining:

  20. Team radio

    Sebastian Vettel: OK, something's not right, I'm losing time down the straights. His engineer Rocky replies: "OK, we don't see anything wrong, please try again."

    Vettel comes back: "There was a clear feeling on the straight when I started losing power. Rocky replies: "OK, at the moment, we think it might be a headwind."

    Frosty. Vettel is leaving Red Bull at the end of the season, of course.

  21. Post update

    The order is unlikely to change now as drivers and teams have switched their attention to long-runs to gather data for Sunday's race. One of the aspects they will be looking at is how the tyres degrade and wear on heavy fuel loads so they can formulate strategy plans.

    Nico Rosberg looks set to close the gap on Lewis Hamilton, but then runs wide at Turn 17.

    So it looks like the best times on the soft tyres will come after a couple of laps. That could make qualifying interesting as timing - and making space - will be crucial.

  26. Post update

    Jenson Button improves on his next lap with a 1:40.718, but he's bumped down by Nico Rosberg. Kevin Magnussen delivers a stunner, to go quickest, but none of them are a match for Lewis Hamilton, who is the first man into the 1m39s with a 1:39.817.

  27. Post update

    Lewis Hamilton's soft tyre effort is disappointing, the Briton going fourth quickest, two tenths off the pace and behind the two McLarens.

    Nico Rosberg reasserts his authority with a 1:41.027, 0.169 seconds clear of Jenson Button (pictured) in second. Kevin Magnussen then splits them, slotting into second just 0.038 seconds off the pace.

    "Jules Bianchi's accident has revived discussion about the wisdom of closed cockpits in F1, or at least some form of forward head protection. Many of the drivers admit to being conflicted on the issue. Fernando Alonso was the man who had been most been at risk of being hurt in an incident such as this in recent years, when Romain Grosjean's Lotus flew over his car's nose in Spa two years ago.

    "'Even in my case, in 2012 at Spa, I probably could have died there in corner one if it had been 10cm closer to my head. If the technology is there available and there is the possibility I would not exclude [closed cockpits] for sure. I probably tend to agree we should at least check and try or test the idea.'

    "Sebastian Vettel added: 'I've got sort of mixed feelings. For F1 cars since the beginning of F1, and open-wheel racing, [open cockpits] is one of the things that is very special. On the other hand, as Fernando has touched on, there are a lot of reasons to look at closed cockpits for the future.'"

    "One word cropped up a lot when drivers were asked about the new Sochi track - Valencia. The long straights and plethora of right-angled corners are indeed very reminiscent of the now defunct Spanish street track which last hosted a race in 2012.

    "Valencia was not exactly known for producing great races - although the last one was a stonker, with Fernando Alonso winning from 11th on the grid - but Nico Rosberg said he thought Sochi would provide plenty of opportunities for overtaking.

    "There are a couple of interesting areas, too - the long, negative camber left-hander of Turn Three will put the front right tyre under a lot of strain, and the last sector will be critical in getting a good lap time, with lots of fiddly, technical corners coming one on top of the other."

    "Along with the focus on Jules Bianchi's injuries, the drivers have been reminded - as if they needed to be - of the dangers inherent in what they do. 'The cars are as safe as they can be,' Lotus driver Romain Grosjean said. 'I know the risks we take. We love the sport. We know it's dangerous. My wife knows it's dangerous. The day you are scared of what you do, you stop. I am in love with F1 and I know Jules was as well. I think if he could say anything, it would be: "Come on, guys. You have a grand prix to achieve. Go for it."

    "World champion Sebastian Vettel added: 'We all share a common passion for racing and competing. We are fortunate to find ourselves in F1, the best and quickest cars in the world with the best excitement and probably the best satisfaction. But there is always some risk involved, which is I think always a part, a great part, of the feeling why you feel so alive. If you have to make a decision, I'm fairly confident you'd always prefer to go racing.'"

    "I don't know how to put into words how truly devastated I am by what has happened to Jules," says Marussia's Max Chilton.

    "The support from the F1 family has been incredible and all we can do is be there to support Jules' family at this difficult time.

    "It is going to be a very emotional weekend for the whole team, but we will try to get through it and keep praying for Jules."

    Marussia add: "Jules' car crew have built a second car, which has been scrutineered and is ready to race, and this will remain on his side of the garage throughout the weekend.

    "In support of Jules and his family, the team and its cars will carry the familiar #JB17 graphic, to ensure that although Jules is not with us in Sochi this weekend, he is, nonetheless, racing on with the Marussia F1 Team."

    Marussia say in a statement: "We will run a single car for the duration of the forthcoming grand prix weekend in Sochi, out of respect for our driver Jules Bianchi, who remains in hospital in Yokkaichi, Japan, in a critical but stable condition.

    "We have written to the stewards of the meeting to inform them that we have withdrawn our second car.

    "The team feels strongly that fielding a single car, that of driver number four, Max Chilton, is the appropriate course of action under the difficult circumstances of the weekend."

    "There is only one real topic of conversation so far this weekend, and that's the terrible accident suffered by Jules Bianchi in Japan last Sunday. The Frenchman is in a critical condition in hospital in Yokkachi and all the drivers have him foremost in their minds. Ferrari's Fernando Alonso, who knew Bianchi better than most as a result of the Marussia driver's position in the Ferrari young driver programme, spoke for all his colleagues when he said: 'It was a tough weekend, and now we are here - a difficult weekend again, emotionally very difficult. We are ready to race, for him, being as professional as we can, but our mind - or my mind - is with him at this moment.'"
