    Kimi Raikkonen

    And that's a wrap. Thanks for your company and hope to see you tomorrow when we can do it all over again before waving goodbye to Jerez for another year. Until then, it's good afternoon from me. Adios!

  2. Post update

    Lewis Hamilton

    Lewis Hamilton will swap his bike for the Mercedes W06 tomorrow for the final day of this first test in Jerez. Jenson Button will be in action, too, as will Romain Grosjean, who will get his first go behind the wheel of the new Lotus.

  3. Post update

    So an encouraging day for McLaren, albeit it one which was curtailed because of an engine issue. Mercedes will be pleased with another 150 laps in the bag, which brings Nico Rosberg's lap total this week to an staggering 308.

    Sauber and Toro Rosso managed more than 100 laps, too, while Ferrari and Lotus almost made the century. It was less successful for Red Bull who missed much of the day before a late flurry of laps from Daniel Ricciardo.

  4. Post update

    Mercedes: That's a wrap for @nico_rosberg @circuitodejerez! Nice touch on his in-lap radio: "Thank you everyone - really top job to start to the year".

    With one minute to go, we have a red flag!

  9. Post update

    Still no signs of any improvements at this stage, with Pastor Maldonado completing his final run before handing the car over to Romain Grosjean, who has yet to drive the car, for the last day of the test.

  10. Ten minutes to go

  12. Post update

    Nico Rosberg

    F1 journalist Dan Knutson in Jerez: "Pit stop practice during a long run of laps by Nico Rosberg. The Mercedes W06 is covered in green flow-vis paint, so the mechanics will have lots of cleanup to do tonight."

    F1 journalist Dan Knutson in Jerez: "Work has been going on behind the screens in the Red Bull garage for most of the day.

    "With Daniil Kvyat doing 18 laps yesterday and Daniel Ricciardo doing just 12 so far today, it really has been a couple of wasted days for the team as far as getting mileage on the car is concerned."

  33. Post update

    F1 journalist Dan Knutson in Jerez: "Like the rest of the teams, Williams plan to put a number of upgrades on their car. Williams will run their Australian Grand Prix spec car, or something very close to that version, at the last pre-season test.

    "'We are going to see changes between now and Melbourne,' chief technical officer Pat Symonds said. 'You will see them in the final days of the final Barcelona test.'"

  34. Nasr back on top

    But back comes Felipe Nasr, the Sauber driver clocking a 1:21.545 to bump Kimi Raikkonen down to second. We shouldn't read anything into this really, as we don't know what fuel loads they're running while different tyre compounds will also have an affect, too.

  35. Raikkonen goes quickest

    Kimi Raikkonen

    It's straight down to business for Ferrari's Kimi Raikkonen as the Finn pumps in a 1:22.351 which sends him flying to the top of the timesheets.

  42. Post update

    McLaren add: "We can replace those components ahead of running tomorrow. The issue was promptly spotted by Fernando on an out-lap - so quick to trace."

  43. McLaren end day early

    It was all going so well for McLaren this morning, but the team say their day is done. "We've had a loss of cooling water pressure & have removed the power unit for inspection," tweet the team. "That's a long process, so it ends today's running."

  44. Post update

    Pace-setter Felipe Nasr dives back into the pits, as he approaches the 50-lap mark. That leaves Felipe Massa's Williams out on track with Toro Rosso's Carlos Sainz Jr for company.

  45. Post update

    Felipe Nasr

    Felipe Nasr is one of three rookies on the grid this season and arrives in the sport having finished third in the GP2 series, collecting four wins along the way.

    The 22-year-old Brazilian gained experience as Williams' test driver in 2014 and lists the 2011 British Formula Three and 2009 Formula BMW Europe titles under his achievements.

  48. Post update

  66. Post update

    Felipe Nasr

    Sauber have stopped for a spot of lunch, with Felipe Nasr currently sixth fastest, 9.254 seconds off the pace. The Brazilian rookie, who had a spin this morning, has completed 30 laps.

  67. Post update

    F1 journalist Dan Knutson in Jerez: They are changing the Renault engine in Daniel Ricciardo's Red Bull. He has done only five laps so far today. It's obviously not a routine scheduled change because the team would have done that last night.

    "Meanwhile, Fernando Alonso headed off to the McLaren hospitality unit, so his car is out of action for at least a short time. He has now completed 32 laps."

  68. Post update

    Why have we seen so little of the Red Bull this morning? Well I have the answer coming up for you...

    "Of the teams we know have survived the winter, only Force India were behind Lotus in terms of readiness for the start of testing. Force India have stayed in the UK and are planning only to do the final two Barcelona tests. Lotus, meanwhile, after planning to miss the first two days in Jerez because of delays in preparing the car, managed to get themselves ahead of schedule and Pastor Maldonado did a useful 29 laps on Monday before he was halted by a drivetrain failure.

    "He said the car was 'a different car, not a continuation of last year', which is probably no bad thing after Lotus's dire 2014. 'We ran with a lot of fuel, we didn't touch the set-up, but the car seems to be consistent, quite reactive, easy to feel, the sensations are good. It's a good day, a good first day,' the Venezuelan said."

    Fernando Alonso

    "Fernando Alonso is not exactly setting the timing screens on fire but nevertheless this is a much more encouraging morning so far from the McLaren-Honda. After just two hours, the two-time champion has already completed nearly 20 laps - more than the Honda engine had completed over four previous days in a McLaren at this test and the post-season one in Abu Dhabi. Even once the track dries out, though, don't expect Alonso to start posting quick laps.

    "The key for McLaren-Honda this week is to learn how and whether the car works, in terms of reliability rather than performance. As team-mate Jenson Button said on Monday: 'It won't be about set-up work, it'll be putting mileage on it. The important thing is to get our heads down and work through all the systems. We will not be setting the world on fire with lap times or laps on circuit. We are still at zero in terms of understanding our performance."

  93. Post update

    Fernando Alonso is clocking up the laps in the McLaren. The Spaniard has managed 16, which is more than was achieved on day one and day two combined. It looks like things are starting to go in the right direction.

    "But the car looks noticeably more bulky than some of its rivals and the appearance of both men towards the top of the speed trap times suggests it is running pretty light on fuel. The team, though, are making positive noises, and head of track engineering Giampaolo Dall'Ara says they 'seem to have a good basis to work from'."

    "Monday was not a good day for Red Bull. Daniil Kvyat went off on an out lap early in the morning and damaged the front wing mounting pillars. There were no spares, so the team were forced to run without a front wing for the rest of the day, which meant only systems checks were possible.

    "A slightly chastened Kvyat admitted: 'These things happen and they happened to me at the wrong moment. I was going very slowly but sometimes it is not even enough. Many factors. You don't spin many times on the out lap. One of the smallest incidents I had but one of the most costly ones.'"

    Ferrari

    F1 journalist Dan Knutson in Jerez: "As you can see from this photo from Monday, the Ferrari guys are using eight screens on wheels to hide the new car as it comes into the pits. They set up the screens on three sides, and then as soon as the driver pulls into the slot the mechanics quickly pull two of the screens around and completely enclose the car.

    "Given that the Ferrari was the quickest car on the first two days of the test, perhaps the team has something worth hiding, although it's worth pointing out that they employed the same tactics in testing last year, too."

    "After a quite remarkable 157 laps by Nico Rosberg on the first day of testing for Mercedes, Lewis Hamilton experienced the team's first reliability hiccup on Monday with a water leak caused by a failed part. But it was a measure of the rate at which Mercedes have been knocking out the laps that Hamilton had already done 97 laps by the time the car stopped in the pit lane early in the afternoon session.

    "'I got in a good amount of laps,' Hamilton said. 'I got a good feel for the car, back in quite quickly, so overall it was good.' He added that the car felt 'very similar to last year really, which is a good thing', but with more downforce. The year has started well for Mercedes, for whom Rosberg is back in the car on Tuesday."

    Daniel Ricciardo

    Red Bull have their wing back today, after Daniil Kvyat damaged the only one they had yesterday. A new one was flown in, but that meant Kvyat's running was severely hampered.

    Daniel Ricciardo is in the car today and mentioning him means another excuse for us to use an image of their epic camouflage livery.

    Still quiet on track. I suspect the teams are waiting for the track to dry out. So in the meantime, let's use this lull in the action to get some F1-related chat going.

    Do you think McLaren can turnaround their fortunes? Have Mercedes already got this season tied up? Will Red Bull and Ferrari get closer?

    We've seen every car apart from the Lotus (and Force India who aren't here, obviously) this morning, but the track has now fallen silent.

    Approximately 0.2 mm of rain fell in the 20 minutes leading up to the start of testing this morning, so rain tyres have been the order of the day so far.

    "Leaving aside McLaren's problems, Sebastian Vettel and Ferrari have grabbed the headlines so far in testing, with the fastest time on both the first two days. Vettel, who hands over to new father Kimi Raikkonen today, was given a round of applause by the Ferrari pit crew after returning to the pits at the end of the day, and joked that they were just pleased he hadn't damaged the car in the damp conditions.

    "Vettel says he has been encouraged by progress so far. 'It is still very early to tell because it depends on how you compare to other people,' the four-time world champion said. 'Mercedes are doing extreme long runs, and in that regard it is difficult. I am quite happy with the feeling inside the car and I think we have a good platform to work from.'"

    Kimi Raikkonen

    Kimi Raikkonen heads out with an aerodynamic device strapped to the Ferrari for his early runs. The Finn is taking over from Sebastian Vettel, who spent the first two days in the car.

    Nico Rosberg

    Nico Rosberg is out early setting the pace, the Mercedes driver leading the way with a 1:33.058, 1.7 seconds clear of Daniel Ricciardo's Red Bull.

    It's been a pretty busy opening half an hour already, with Carlos Sainz Jr, Felipe Nasr, Fernando Alonso and Felipe Massa also posting times.

    McLaren's Fernando Alonso completes two successive laps to put a time on the board - a 1:42.304 which is seven seconds off the pace. Still, it's a lap.

    Brands Hatch

    The conditions are far from ideal in Jerez, with the track damp and greasy. But that's nothing compared to what it's like over at the legendary Brands Hatch in snow-hit Kent.

    Mercedes

    Nico Rosberg is the first man out on track, with Kimi Raikkonen, Daniel Ricciardo and Fernando Alonso joining him. Yes, you read that right, Alonso in the McLaren is out on track. How long that lasts is anyone's guess.

    Nico Rosberg is back behind the wheel of the Mercedes today, with Daniel Ricciardo making a return for Red Bull.

    Felipe Massa gets his first taste of the new Williams, while Fernando Alonso is back in at McLaren.

    Kimi Raikkonen takes over from Sebastian Vettel at Ferrari, Carlos Sainz Jr is testing the Toro Rosso, Romain Grosjean gets a go in the Lotus and Felipe Nasr is in action for Sauber.

    Only Force India are not at this test, after deciding to concentrate on the final two Barcelona tests.

    Fernando Alonso

    "It's all eyes on McLaren on Tuesday morning. After two days in which Fernando Alonso and Jenson Button have managed just 12 laps between them because of a recurring control-systems issue on the Honda engine, it is time the team got some serious work done. Button and McLaren both said on Monday evening that they felt they had found the problem, and they are about to find out whether they are right.

    "Despite the trying start to the programme - remember this comes after they completed just five laps in two days with a 2014 test car fitted with the Honda in Abu Dhabi last November - so far, they have stayed resolutely positive.

    "'We've had a few little niggly problems, control issues but we feel the last run was good and we've solved them so hopefully the last two days will be much better,' Button said. 'The packaging and how tight the bodywork is and temperatures; all that stuff is working really well.

    "'But if you've only done six laps that's what people see. I'm sure we'll have more problems over the next couple of days - these engines are so complicated - I just hope we can do a bit of running and get a bit of data back to the factory and see where we are and where we need to improve.' Alonso is back in the car on Tuesday."

    Sebastian Vettel

    There's no point reading into headline times because we don't know the spec in which each team is running their car, nor do we know fuel loads.

    But Ferrari and Sebastian Vettel will still be pleased with their efforts so far as the German finished top of the pile on both days and racked up a solid amount of laps.

    It's been pretty positive for Mercedes, too, aside from a water leak which curtailed Lewis Hamilton's running yesterday. Still, the team have completed nearly 250 laps - significantly more than anyone else - in two days.

    It hasn't gone so well for McLaren, though.

  131. Post update

    It is considerably warmer this morning than on the first two days of the test, with the air temperature hovering around 10.4C and the track temperature 9.4C.

    Today's session has just got under way and will run until 16:00 GMT. That's eight hours for the teams to continue putting their 2015 challengers through their paces and iron out any issues as the new season approaches.

    Hello all and a warm welcome to our live text commentary of day three of pre-season testing in Jerez, southern Spain. We've had two days of testing already but the good news is that there is still two more to go!
