Hello and welcome to ESPN's coverage of the final pre-season test this week in Barcelona. I don't want to panic the teams, but there is just TWO DAYS LEFT of this test and the next time the cars will run after that is in Australia at the first race.
To add to those two team tweets, Raikkonen, Ricciardo and Massa have also gone out for early installation laps
@aftab: We saw the quickest lap of the test (by some way) from Nico Rosberg yesterday, so logic would dictate that Lewis might be let loose on the soft compound tyres today, but it all depends on what Mercedes still needs to achieve. If they don't have time or have better things to do (they must be pretty satisfied with Rosberg's efforts) they may just keep the car fat with fuel today. Time will tell.
Ferrari says it will finally attempt a qualifying and race simulation today. So for all those that have been asking over the last two days, we might now see the true pace of the SF15-T.
@Sulaiman: It may wait until Australia. The key today is to try to match the mileage of yesterday, which was more of less another 50% of what they had achieved on the previous nine days of testing. The car is still a long way from being perfect and there are still aero tests being carried out and all sorts of other tests to conduct.
What's more, we are expecting Kevin Magnussen to drive today, so there's not a huge amount of sense in getting him to work on set-up and performance as he won't be driving in the races this year.
@Sulaiman: The gap was closer to 0.75s, but judging by the reaction in the paddock yesterday that could be quite representative. Bottas admitted he was surprised by the pace of the Mercedes.
@JonnyDietrick: We can confirm it is definitely Kimi Raikkonen at the wheel today. Seb is back tomorrow.
@NorbertHaug: 4.2C to be precise, but it is nice and sunny so it feels warmer. Track temp is 16.7C. Good to have you back, Norbert.
Installation laps from all the teams bar McLaren so far.
We sent Nate up to the roof of the media centre for a weather report and he tweeted this image back. He says it feels warmer than the 4.2C flashing up on the timing screens.
@aftab: It is 9:17am but feels much earlier now we are in the 11th day of testing and everyone is a bit knackered. Time for some sun down under, I say.
@ENGonzaga: More of the same - miles, miles and more miles. A lot of yesterday was about running basic system checks, something the other teams managed in Jerez. However, it all went well for Force India so they are confident of another strong day learning as much as they can about the new VJM08
@Rauque: Still no official news on whether he will race, but Alonso released a video yesterday saying he feels absolutely fine and wants to get back in the car. It will come down to doctor's orders, but the signs are that Alonso will be healthy enough in two weeks.
@ankur: Sadly not. We've been promised an "even better" livery by Christian Horner, but I suspect it will be the more familiar Red Bull Racing colours
@Thif: The plan is for both - a bit like condensing a race weekend into one day. It's Raikkonen's last day, so a lot of it will be about making sure the car is reacting to all his demands from the cockpit.
@mike: We have yet to determine if it is the real Norbert Haug. If it is, he is very welcome indeed.
@MrsHamilton: It varies team to team. Some teams will have the second chassis here this week, others will be bolting them together back at the factory. Quality control is pretty high in F1 so they should be identical, but it's true that drivers often stick to a chassis until something goes wrong or there is a significant upgrade. Usually in F1, new components are preferred to old ones.
