Kimi's last few laps on the hard tyre:
@Nikhil: We don't have that data available to us. We get the tyre data by looking out of the press room window, but it's easy to miss one as we are also conducting interviews and digging for information in the paddock.
Kimi pits after 14 laps on the hard tyre. That should bring him to around 36 laps of the race simulation overall.
Kimi has just flashed past the media centre sporting the winter development tyre.
@MclarenFan: I'm not sure. McLaren tweeted an hour ago that Magnussen was "suited and booted" so maybe a problem cropped up before he could leave the garage...
@Leo: His best time was on super-softs but he is now doing a race sim in which he has used the medium, hard and development tyre.
@super: Impossible to tell. Vettel hasn't done a race sim yet, but even when he does one tomorrow a direct comparison will not be possible due to varying track conditions.
@thehulk: Kimi is on a race sim, Hulkenberg was doing early checks with the car. It doesn't prove anything.
We're currently being treated to a farcical display of camera use in the media centre. The CCTV camera (which is just focused on one part of the track, the exit of Turn, for much of the day) is currently focusing on a woman eating what looks like a rather soggy ham roll.
The camera briefly pans to a pillar, then to the wall, before resuming its old position looking at the track - albeit too far back for it to be of much use at all.
@Sulaiman: It should be more than that. Fuel loads or engine setting are more likely to be the reason for the close gap. However, the super-softs do struggle here by the final sector as they can easily overheat if the driver is overzealous in the first two sectors. Plus those are two times on two different days with different track conditions.
@Leo: It looks tight to be best of the rest this year. Everybody wants to be in the position Daniel Ricciardo found himself in three times this year, but that requires a lot skill from the driver and a very good car. Ferrari look as though they may be in the running, so assuming Mercedes slips up from time to time two wins is possible.
Kimi has just completed lap 100 of today and lap 49 of his race sim.
@LachuChelsea: It's very unlikely any of the cars has a fuel tank big enough for more than 100kg of fuel. It would be bigger than it ever needs to be and space and weight are crucial in an F1 car.
His lap times since pitting for the development tyre:
@Leo: They were the most reliable team during testing last year. I'd be more surprised if they had 100% reliability this year. Plus the gap may change during the season. Ferrari has said it will save some token spend on its PU for later in the year.
@Siddhesh: They can work on the car overnight and they do work on it overnight. However, if Hamilton wants to try something new on the car this is his last chance. Judging by the length of the stoppage, however, there may be more than just a set-up change.
Kimi's last ten last on the development tyre - pretty consistent stuff from the Finn:
Though as I say that, his 60th lap of the simulation is a 1:29.108. Six laps left for the Finn.
@Canuck: True, we've been through this several times today. But Mercedes and Renault have said they want to spend big for the opening round, whereas Ferrari have said they will spend "only a few" at the start of the year. That was Mattia Binotto at the launch, so it is possible their plans have changed during testing.
