As it happened

  1. 1635: 

    Right then, that's it from me today. Ferrari and Mercedes look good but Red Bull are in all sorts of bother.

    Catch up on the action from today in Andrew Benson's report and keep an eye out for his correspondent piece later on today.

    We'll also have the best video interviews up, too. Thanks for your company and contributions. It's been a pleasure. Until next time, it's goodbye from me.

  2.  

    Williams driver Valtteri Bottas: So that's it for the Jerez tests. First impressions positive, we improved and learnt everyday a lot. We will keep pushing!

  3. 1627: 

    Kamui Kobayashi had a decent return to Formula 1 with Caterham today, clocking up 54 laps before a power unit issue ended running early.

    "My first day in the car may have ended earlier than we'd planned after another problem with the Renault engine, but, from where we've been earlier this week, it's very good to have completed 54 laps," said the Japanese driver.

    "For me, it was also good to be back in an F1 car and to be working with a team that I'm already feeling very happy with."

    Jack Walton: Red Bull keep saying it's not been that bad, which begs the question: how could it have gone any worse!?

    They could have done no laps at all...

  5. 1622: 

    Red Bull have a lot of work to do between now and the 19 February when the second four-day pre-season test begins in Bahrain. A third and final test follows in Bahrain before the season starts in Melbourne with Friday practice on 14 March.

  6. 1616: 
    Completed laps

    Ferrari's Fernando Alonso completed the most laps of the day, clocking up 115, with Kevin Magnussen the next best with 110 in the McLaren.

    Nico Rosberg did 91 in the morning session before handing the Mercedes over to team-mate Lewis Hamilton who added another 41 laps.

    Elsewhere, Williams' Felipe Massa did 86, Force India's Daniel Juncadella 81 and Daniel Ricciardo just seven in the Red Bull.

  7. 1611: 
    Final day timesheets

    1 Felipe Massa (Williams) 1:28.2

    2 Fernando Alonso (Ferrari) 1:29.1

    3 Daniel Juncadella (Force India) 1:29.4

    4 Kevin Magnussen (McLaren) 1:30.8

    5 Lewis Hamilton (Mercedes) 1:30.8

    6 Jules Bianchi (Marussia) 1:32.2

    7 Adrian Sutil (Sauber) 1:36.5

    8 Nico Rosberg (Mercedes) 1:36.9

    9 Kamui Kobayashi (Caterham) 1:43.1

    10 Daniil Kvyat (Toro Rosso) 1:44.0

    11 Daniel Ricciardo (Red Bull) 1:45.3

  8. 1605: 

    So the session was brought to a premature end, with the Toro Rosso of Daniil Kvyat also stopping out on track.

  9. 1600: 
    CHEQUERED FLAG
    Felipe Massa

    Williams' Felipe Massa finishes fastest on the fourth and final day of the first pre-season test at Jerez.

  10. 1557: 
    Ben Edwards waiting to interview Lewis Hamilton

    BBC F1 commentator Ben Edwards has bagged his spot at the back of the Mercedes garage ready to interview Lewis Hamilton. You'll be able to see that interview on the website later today.

  11. 1552: 

    It's Kevin Magnussen again! This time, the Dane has hit the barriers, breaking the McLaren's front wing.

  12. 1550: 
    RED FLAG

    We've got our third red flag of the day....

  13. 1545: 

    Felipe Massa goes quicker to extend his advantage at the top over former team-mate Fernando Alonso to 0.7 seconds with 15 minutes remaining.

  14. 1535: 

    Lewis Hamilton, Kevin Magnussen and Fernando Alonso are all out on track racking up the miles as the clock ticks down. It's been a useful day for Ferrari, who are well past the 100-lap mark.

  15. 1525: 

    The track continues to dry at Jerez, which means lap times could yet fall further with 35 minutes remaining.

  16. 1520: 

    Frenchman Jules Bianchi is clocking up the laps in the Marussia, and after the last flurry, it now means Red Bull have done the fewest laps of any team this week.

  17.  
    BBC F1 commentary producer Tony Dodgins:
    Daniel Ricciardo

    "Asked how these problems would impact Red Bull's season, Ricciardo said: "I don't think it is going to affect it. We have the best team in the world and they're going to turn this around. We still have time to get back any track time we've lost here. It still feels like a race car, nothing too out of the ordinary."

    "And on rivals pounding out the miles while Red Bull were consigned to the pits, he said: "I don't think it adds pressure. They could be racking up a lot of laps but they could be a second off the pace, we would have loved to do more laps, but we are not going to get down about it.""

  18.  
    BBC F1 commentary producer Tony Dodgins:

    "Despite Red Bull's troubled test here, Daniel Ricciardo was still smiling as he prepared to leave the track. 'We came here to drive, but we also came here to understand,' he said. 'It's a complex system that's not going to take 24 hours to solve. It's good we have some time away from the track.'"

  19. 1509: 

    Felipe Massa currently leads the way, ahead of Fernando Alonso and Daniel Juncadella. Lewis Hamilton is fourth, with Kevin Magnussen fifth and Nico Rosberg sixth.

    Adrian Sutil, Jules Bianchi, Kamui Kobayashi, Daniil Kvyat and Daniel Ricciardo complete the standings.

  20. 1503: 

    Speedy work from the marshals and we're back under way for the final hour of testing at Jerez.

  21. 1457: 

    It's Kevin Magnussen, the McLaren driver spinning down at the chicane.

  22. 1453: 
    RED FLAG

    We've got our second red flag of the day....

  23.   
    BBC Sport’s chief F1 writer Andrew Benson:

    One thing that has been particularly noticeable about the 2014 cars, apart from the lack of miles the teams are managing, is how much slower they have been so far compared to last year. Lap times are a good five seconds or more off last winter's Jerez test. But Fernando Alonso played down the change. "The cars are slower - nothing more than that," he said on Thursday. "I lapped here in one minute 16 in 2004 or 2005 and today I ran in one minute 26, so I'm 10 seconds slower than 10 years ago. When you go 10 seconds slower, it's not the same, also from the physical point of view - these cars are much easier than Formula 1 has been."

    "There are less G forces, less speed into the corners, but there more parameters to control, there are more buttons on the steering wheel. It's more critical to drive and to control the car in the high-speed corners and in terms of traction. It's just different. In terms of emotions, it's the same. When I drive a go-kart I go 20secs or half a minute slower than in Formula 1 but I sweat and enjoy so much. If I drive my road car, I'll enjoy it too. As long as you're driving on the limit, the lap time doesn't change the emotions you feel when you drive. This car is still fun to drive and we'll discover better soon."

  24. 1442: 

    The times continue to tumble as first Daniel Juncadella and then Felipe Massa move to the top of the timesheets. The Brazilian drops down to a 1:29.6.

  25. 1435: 

    Jules Bianchi heads out on track in the Marussia, with Daniel Juncadella, Felipe Massa and Lewis Hamilton following.

  26. 1430: 
    GO! GO! GO!

    The marshals have recovered Adrian Sutil's Sauber back to the pits and the track is once again open for business.

  27. 1424: 

    Just before Sutil went off, Fernando Alonso set a new fastest lap of the day with a 1:30.8 in his Ferrari.

  28.   
    BBC F1 commentator Ben Edwards

    "Sutil steps out of the car to a huge cheer. Second time this week he's been caught out by the power delivery."

  29. 1418: 
    RED FLAG

    Hopes of getting through the day without a red flag have been dashed as we've got a Sauber in the gravel.

  30. 1412: 

    Fernando Alonso is up to second, after clocking a 1:32.1 on the 10th lap of his current run in the Ferrari.

  31. 1409: 

    So Caterham join Red Bull in packing up early ready to head back to their respective factories in the UK to work on their cars before the second test which starts on 19 February in Bahrain.

    Still, Caterham managed to get 54 laps on the board today, which is 34 more than Red Bull managed across all four days...

  32.  

    Caterham: Our positive Friday has unfortunately come to a close with a Power Unit component issue ending @kamui_kobayashi's day in the car early.

  33. 1406: 

    Things were going so well for the Renault-powered Caterham team, but the gremlins have struck...

  34.   
    BBC Sport’s chief F1 writer Andrew Benson:
    Fernando Alonso

    "Fernando Alonso ended his first day of running on Thursday fifth fastest, two seconds off the pace of fastest man Kevin Magnussen. But he said lap times were even more irrelevant than normal in pre-season testing. 'It's very early days, way too early to think about this,' Alonso said. 'In the preparation and approach for Australia, we are completely blind in terms of comparative performance. We've got to learn so many things before Australia, just on our side of the running, that I cannot imagine what will be the picture of the grid in Melbourne. Even more than in any other year, we'll only find out in Australia.'"

  35. 1357: 

    Lewis Hamilton's first effort of the day is a 1:40.2, which is good enough for sixth, eight seconds off the pace set by Force India's reserve driver Dani Juncadella.

    Tim Galer: New F1 engines don't sound as good but the tech is awesome and what F1 about. F1 biggest problem is Bernie and his double points farce.

  37.  
    BBC F1 commentary producer Tony Dodgins:

    "More from Nico Rosberg, this time on what the new F1 cars are like behind the wheel: 'Driving-wise it's pretty similar. It's a bit of a pity because the cars are slower; I would always prefer to go faster so that's not quite as nice. But other than that, the big difference is the engine, the low rpm and the gears you use. And then it's how much you need to use your brain to understand the new technology, the fuel-saving, the Ers, that's going to be quite complicated.'"

  38. 1345: 

    Mercedes say Nico Rosberg has completed 188 laps this week, while his team-mate Lewis Hamilton has managed just 80. Makes sense for the team to let the Briton have a bit more time in the car this afternoon.

  39.  
    BBC F1 commentary producer Tony Dodgins:

    "Nico Rosberg has been talking to the media after handing over the Mercedes to team-mate Lewis Hamilton for the afternoon. The German declared himself 'pleased' with the team's progress, adding: 'The goal was to do a lot of miles and we managed to achieve that quite well. It's a surprise to get so many miles. It's a decent start, but we have no idea where we are in terms of pace.'"

  40. 1337: 

    A dry line is starting to form, just as Daniel Juncadella goes quickest for Force India on slick tyres. Meanwhile, in the Mercedes garage, Lewis Hamilton is suiting up for his first run of the day after taking over from team-mate Nico Rosberg.

  41. 1331: 

    The times are tumbling as the track continues to dry. Kevin Magnussen is our new leader, the McLaren driver getting down into the low one minute 35 seconds, nearly two seconds quicker than Fernando Alonso's previous leading time.

  42. 1324: 

    Kevin Magnussen moves into second with a 1:35.7 in his McLaren. Sauber Adrian Sutil improves, too, but he stays sixth.

  43. 1320: 

    Kevin Magnussen and Felipe Massa are out on track. The latter has clocked up 36 laps today in the Williams and has just set his personal best of the day with a 1:39.1.

    Mark Burton: Mercedes look in another league at the moment... but is it quick enough to win? Marussia were reliable last year!

  45.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "It has been interesting hearing the drivers' views on whether the new turbo cars, with their reduced downforce, are different to drive than last year's models. Lewis Hamilton said that 'everything is a little bit different', adding that the tyres were more durable, there was less downforce, more torque. The corners required higher gears, he said, and the new brake-by-wire system - required because of the much greater scavenging demands of the more powerful Kers systems, added to the changes. 'It's so complex; far beyond what we've ever had before,' he said, 'and as a driver you have more functions to juggle than ever before.' Ferrari's Fernando Alonso, meanwhile, echoed team-mate Kimi Raikkonen's view that there was 'no real big difference.' Puzzling."

  46. 1310: 

    Away from the track, F1 boss Bernie Ecclestone says the sport's new V6 turbo era is "completely unnecessary nonsense" after Renault engine woes sidelined champions Red Bull in pre-season testing.

    "I am disappointed. I hate saying 'I told you so', but I'm disappointed because I did say I told you so and this is what's happened," Ecclestone told Reuters.

  47. 1301: 

    Kamui Kobayashi has headed out in the Caterham, just as Fernando Alonso - who is currently fastest - heads back into Ferrari garage, climbs out of the car and strolls into the hospitality unit for a spot of lunch.

  48. 1254: 

    Red Bull race engineering co-ordinator Andy Damerum added: "We did seven laps and every time Daniel went out we made improvements to the control of the engine.

    "We were also making fixes to the issues that have arisen from our side and we have made progress there.

    "However, we then discovered a mechanical issue with the car and after investigation it became clear we would not be able to fix this in time to run in the afternoon.

    "So the decision was taken to retire early, take the data we have amassed and work towards the next test in Bahrain.

    "Two weeks is a long time in Formula 1 and I'm sure Renault will work flat out now to solve the problems we've been having."

  49. 1250: 

    Red Bull say a "mechanical issue" has forced them to head back to their Milton Keynes HQ early. However, team boss Christian Horner says the problems should be fixable before next month's test in Bahrain.

    "It's been a very difficult test," said Horner. "We have had numerous Renault issues as well as chassis-cooling issues, which have affected our progress.

    "However, despite the lack of mileage, what we have managed to learn shows that the problems should be solvable for the next test in Bahrain.

    "Part of the purpose of this early test was to learn about any issues ahead of the start of the season and there will now be a lot of focus on the dyno over the next few weeks."

  50.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "Williams, who are starting an engine partnership with Mercedes this season, are very pleased with their progress so far, saying they feel generally on top of things and have been especially happy about the new car's reliability. 'If we carry on like this we'll be doing a race distance (on Friday),' chief test and support engineer Rod Nelson said."

  51. 1244: 

    Red Bull have managed just 20 laps across four days of testing - and most of those were installation laps. In contrast, Mercedes and Nico Rosberg managed over 90 laps this morning alone.

  52. 1238: 
    Red Bull end Jerez test early
    Red Bull team members put a screen up in front of their garage

    Red Bull say they have finished testing for the day. "All focus now shifts to Bahrain," tweets the team. "Full update to come shortly."

  53. 1236: 

    Kamui Kobayashi continues to clock up the miles in his Caterham. "Don't tell him, but there's katsu curry for lunch," tweet the team.

  54.  

    Williams: All calm in the garage as Felipe and the boys grab some quick lunch before we get into our afternoon programme #Jerez.

  55. 1230: 

    If that is the case, it brings to an end a miserable opening test for the reigning world champions. But let's not forget, Red Bull missed the first test in 2010 and went on to win both the drivers' and constructors' titles that season and in the next three years.

  56.   
    BBC Sport’s chief F1 writer Andrew Benson:

    That's it for Red Bull for this test, I'm told. Not officially confirmed yet.

  57. 1220: 

    We've got three rookies on the grid this year - McLaren's Kevin Magnussen, Toro Rosso's Daniil Kvyat and Caterham's Marcus Ericsson.

    Magnussen, son of Jan who also drove for McLaren, has earned a race seat with McLaren after winning the Formula Renault 3.5 series title.

    Kvyat, meanwhile, has been winning, too. The Russian triumphed in the GP3 series, two runs below F1.

    And Ericsson joins the sport with the 2007 Formula BMW UK and 2009 Japanese F3 title under his belt, plus a sixth-place finish in GP2 last year.

    How do you expect them to get on this year? Tweet us using the #bbcf1 hashtag or text 81111 (UK only), remembering to put F1 and your name at the start of the message.

  58.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "The need to understand the immensely complicated new cars has meant very few drivers have had off-track incidents in Jerez. Sauber's Adrian Sutil, though, was an exception on Thursday. He held up his hands and said his crash at Turn Seven was caused by driver error.

    "'It's very, very tricky with the new cars [in addition to] low grip and very cold temperatures as well,' the German said. 'It caught me out on an installation lap. We had several issues with the engine and the tyres got colder and with the combination of cold tyres and turbocharger, the torque amount came in too aggressively and I lost it in a very strange way. It was kind of a small incident and we just had to do a nose change. And the suspension was a bit damaged.'"

  59. 1210: 

    Fernando Alonso has moved to the top of the timesheets in his Ferrari with a 1:35.3. Nico Rosberg is 1.6 seconds further back, ahead of Kevin Magnussen, Felipe Massa, Dani Juncadella, Kamui Kobayashi, Daniil Kvyat, Adrian Sutil, Daniel Ricciardo and Jules Bianchi.

  60. 1200: 

    We've got a change of plan at Mercedes, with Nico Rosberg - who has been super busy this morning - making way for Lewis Hamilton.

    Hamilton lost most of the first day following a front-wing failure, so it's a case of the team being fair to both drivers.

  61.  

    Marussia: Lunchtime in Jerez. We've done some work with the brake by wire system & its interaction with the powertrain. Out again in a little while.

  62.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "Daniel Ricciardo has been out in the Red Bull this morning, but he has managed only seven laps. That has raised their total for the week by 50% but it would suggest Red Bull and Renault have not been able to find the 'workaround' solution to allow some proper running on the final day of this test for which they had hoped. There is still the afternoon to go, but that almost certainly means the two will need to spend the two weeks between Jerez and the second test in Bahrain finding a solution. It's certainly a drama. Is it a crisis? Not yet, perhaps, but it has the potential to become one."

  63. 1147: 

    It doesn't look like there's time for lunch for Kamui Kobayashi, though. "Lunchtime on day 4 in Jerez," tweeted Caterham. "So far we have completed 41 laps with Kamui in the car & we're keeping him strapped in so we can add to that..."

  64. 1138: 
    Nico Rosberg

    Nico Rosberg is so dedicated to his work, he's spurned the warmth of the Mercedes hospitality unit, where proper plates and cutlery are available, in favour of staying in the garage and shooting the breeze with executive director (technical) Paddy Lowe while eating his lunch out of a plastic box.

  65. 1129: 
    Kamui Kobayashi

    Kamui Kobayashi is clocking up the laps in the Caterham as he becomes reacquainted with the sport. The Japanese was forced to sit out last season, despite a decent effort for Sauber in 2012 which saw him take his first podium. However, helped by his fans, who raised over £1m, he secured the Caterham drive - which he says he is doing for free.

  66. 1120: 

    Nico Rosberg is in the pits, having just crossed the 90-lap mark. Impressive reliability from the Mercedes.

  67.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "Lewis Hamilton has finished his running for this test, and has handed the Mercedes back to team-mate Nico Rosberg for the final day. The Englishman said he was very satisfied with Mercedes' work so far, particularly the amount of running they had been able to do.

    "'Proving reliability at this stage is crucial and every lap is precious, as this is going to be a seriously challenging year for every team,' he said. 'I'm feeling very positive after these tests and every day on track is another step forwards, but there are so many challenges ahead of us in the coming weeks and months that we just have to take those steps one at a time.'"

  68. 1110: 

    It's a Mercedes-powered 1-2-3 at the moment, with Nico Rosberg heading Kevin Magnussen and Felipe Massa. Fernando Alonso is fourth in the Ferrari-powered, er, Ferrari.

  69.  

    Williams driver Valtteri Bottas: Good 'race distance' training session with @jaska80 this morning after the engineering briefing ;) Now back to track to follow the tests!

  70. 1101: 

    Nico Rosberg has just further improved on his previous best, dropping down into the 1:36.9s. That puts him around 1.4 seconds clear of Kevin Magnussen in the McLaren.

  71. 1059: 
    BBC commentary producer Tony Dodgins:

    "I have been watching trackside and Nico Rosberg's Mercedes is already over 75 laps for the day, which is impressive (the race distance at that controversial '97 title-decider between Michael Schumacher and Jacques Villeneuve was 69 laps.) It does, however, have a very different engine note today, almost like a sickish-sounding low-powered motorcycle. A wet weather engine map is the most likely explanation."

  72. 1055: 

    Wouldn't it be great if you could see all the new cars - and those noses - for 2014 in one place? Well, you're in luck. Check out our gallery on the F1 pages.

  73.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "The problems encountered by Renault at this test mean Lotus's decision to skip it - forced on them because their car was not ready - is not anywhere near as big a blow as it first appeared. Drivers Romain Grosjean and Pastor Maldonado have been at the factory this week, and former team principal Eric Boullier - appointed racing director of McLaren this week - is popping in on Friday to say his goodbyes.

    "Money is tight at Lotus, as ever - there are unconfirmed reports of redundancies - and they currently do not have a team principal (owner Gerard Lopez is temporarily filling in for Boullier). But insiders say the new CEO Matthew Carter, who has replaced the unpopular Patrick Louis, has made an impressive start to his new job and are confident they will be fine this season."

  74. 1045: 

    It's still intermediate weather out there, but that's not stopped the teams heading out on data-gathering missions.

    Nico Rosberg is still quickest and comfortably has the highest tally of laps. The German is still out there, along with Fernando Alonso, Kamui Kobayashi, Adrian Sutil and Daniel Juncadella.

  75. 1035: 

    Nico Rosberg passes the 60-lap mark. The German is really motoring, having completed more than double the number of laps than anyone else. The Mercedes driver took two wins and three pole positions last year on his way to sixth in the championship. Can he improve on that this year?

  76.  

    Mercedes: Rain appears to have ceased here at #Jerez; not that it's affected running, but some sunshine wouldn't go unappreciated!

  77.   
    BBC Sport’s chief F1 writer Andrew Benson:
    Kamui Kobayashi

    "The noses on the F1 cars have been attracting a lot of attention for their general ugliness, but governing body the FIA is also unhappy with many of them. The 'anteater' design chosen by many teams, with a phallic appendage at the front, satisfies the letter of the rules but not the spirit. And FIA race director Charlie Whiting is concerned they may also not satisfy the intention, which was to reduce the risk of a car taking off if it hit another from behind a la Mark Webber at Valencia in 2010. Whiting has asked all the teams to supply cross-sectional drawings of their cars' noses so he can assess their construction. It is unlikely anything will happen for this year; it's more to ensure a rule is written for 2015 to stop such monstrosities appearing again."

  78. 1025: 

    If you've missed what's been going on in Jerez this week, may I suggest giving this video a look. Lee McKenzie and Ben Edwards talk you through Red Bull's struggles and Kevin Magnussen's impressive start - with some moving shots of cars and sounds of the new V6s thrown in, too.

  79. 1020: 

    Lots of action out on track with Nico Rosberg, Kevin Magnussen and Felipe Massa being joined by Kamui Kobayashi's Caterham.

  80.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "F1 boss Bernie Ecclestone has been a vocal opponent of the new Formula 1 for years, and he continues to rail against it now. Talking to UK newspapers, he has condemned the problems being suffered by the teams in Jerez, saying: "Look at the last few days. I said it was going to be like this — a total farce. They insisted on these new engines. They talk about saving fuel. They don't need these new engines to achieve that. They should get smaller motorhomes, then they wouldn't need so many trucks going all round Europe. The whole thing with the new engines is totally absurd. People want noise — something special, that is what F1 is all about. Now we have quiet engines and nobody on the track.' Ecclestone then admitted: 'The season could be really unpredictable and that is the exciting thing.'"

  81. 1009: 
    Nico Rosberg

    Nico Rosberg improves to a 1:37.5 to extend his lead at the top of the timesheets. The German is joined out on track by Felipe Massa in the Williams.

  82. 1007: 

    Mercedes' Nico Rosberg pits, sticks on a fresh set of tyres and then heads back out on track. The German has completed more than 40 laps of running already today.

  83. 0959: 

    It's all going rather well for Mercedes at the moment, as Nico Rosberg continues to pound round Jerez doing what looks like a race simulation.

  84.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "There's always a bit of a technical dispute at the start of any new F1 season, and this year is no different. One of the main topics this week is McLaren's trick rear suspension wishbones, which are shaped like little wings. The idea is to make up for some of the deficit caused by the loss of the lower rear beam wing, which made the diffuser work more effectively.

    "Some teams have been grumbling that the suspension shape is clearly there for aerodynamic reasons and therefore should be considered illegal. But the FIA disagrees and sees no problem with it. Teams are, though, still free to lodge an official protest at races if they wish."

  85. 0955: 

    With almost two hours gone, here's how they stand: 1. Rosberg 1:38.157 2. Magnussen 1:38.391 3. Massa 1:39.313 4. Alonso 1:39.999 5. Juncadella 1:41.925 6. Kvyat 1:44.016 7. Sutil 1:44.224 8. Kobayashi 1:44.859 9. Ricciardo 1:45.374 10. Bianchi 1:48.192

  86. 0950: 

    Fernando Alonso finally gets on the board, the Spaniard clocking a 1:39.9 to go fourth fastest in the Ferrari, 1.8 seconds off the pace.

    "After little track time this week, shame for @NicoHulkenberg not to get valuable running today. 3rd driver Dani Juncadella in the Force India."

  88. 0942: 

    Nine out of the 10 teams in action today have posted a time, with only Fernando Alonso in the Ferrari yet to do so. Lotus, of course, are not in Jerez as they continue to work on the development of their car back at based. Expect to see their car break cover in Bahrain next month.

  89. 0935: 

    Talking of McLaren's Kevin Magnussen, the 21-year-old Dane goes second quickest, just two tenths slower than the Mercedes of Nico Rosberg.

  90.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "McLaren's new recruit Kevin Magnussen was the star of the third day of the test, setting fastest time of all on his first afternoon in the car, and by some margin, and looking, to all accounts, like he was born to it. Magnussen is both disarmingly frank and laid-back and phlegmatic, and he admitted to 'butterflies in my stomach and had trouble sleeping last night - I'm a rookie, and I was just excited to get in the car'.

    "But he added: 'This doesn't feel like my first day at work: I know everybody at McLaren, so I really felt at home.' The lap, he said, was far from his ultimate potential. 'It wasn't a balls to the wall lap, (but) we were pushing, we are trying to get good data and learn about the car.' And he was refusing to get carried away by it: "As we all know it is winter testing and nobody really knows what the other cars were doing so not looking into it too much.'"

  91. 0925: 

    The track is drying which means intermediate tyres, rather than full wets, look like the tyre of choice. McLaren's Kevin Magnussen and Williams' Felipe Massa head out on the inters, which are marked with a green stripe.

  92. 0919: 

    Kamui Kobayashi, Japan's most successful F1 driver, has set his first timed lap of the day - a 1:50.2 which is 12 seconds off the pace set by Nico Rosberg. Seven drivers have set a time, with Massa second ahead of Kvyat, Ricciardo, Sutil and Bianchi.

  93. 0912: 

    Kevin Magnussen has headed out and about in the McLaren, with Jules Bianchi, who is getting his first chance behind the wheel of the new Marussia, following the Dane out.

    Get involved- #bbcf1

    Wizbit: Have followed F1 for at least 20 years and this is the most excited I have felt coming into a season - Merc all the way. Go Lewis!

    James Haigh: I never delight in anyone's misfortune but Red Bull stumbling out of the blocks will really spice up this year.

    Neil Backhurst: Shame to see the potential Renault battery issues. Have they thought of just using a big elastic band instead?

  95. 0905: 

    Nico Rosberg pits after a useful first hour of running. The German has already completed 16 laps in his Mercedes, more than Red Bull have managed all week...

  96.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "It's not just Red Bull in trouble - all the Renault-powered teams have had very limited running, and as one engineer from a team supplied by a rival manufacturer said: 'Obviously Renault have got some kind of nightmare going on.' The word on the street is that there is a problem with the batteries used with the Renault engine. If that's the case, it's possible that Red Bull, Toro Rosso and Caterham will have more difficulties today."

  97. 0900: 

    Daniel Ricciardo has already completed more laps today than he managed all day yesterday. Better news for Red Bull as we pass the one-hour mark of this day-long test.

  98. 0853: 

    Nico Rosberg is doing a run of laps, improving to a best of 1:38.1, with rookie Daniil Kvyat and Adrian Sutil also out there.

  99. 0846: 

    Nico Rosberg moves to the top of the timesheets with a 1:38.7 in the Mercedes. The track is still wet, with Force India reserve driver Daniel Juncadella, who has been out of an installation lap, reporting that there is standing water between turns five and six.

  100. 0840: 
    Get involved

    Can Red Bull recover from a poor start to once again be the team to beat in 2014? Will McLaren fight for podiums and victories once again? Can Lewis Hamilton and Mercedes get it together to launch a credible title challenge? Will Fernando Alonso and Kimi Raikkonen get on at Ferrari?

    So many questions. I'm hoping you've got some answers. Tweet us using the #bbcf1 hashtag or text 81111 (UK only), remembering to put F1 and your name at the start of your message.

  101. 0835: 
    Red Bull go quickest

    Daniel Ricciardo finally sets a lap time behind the wheel of a Red Bull in Jerez - and it's the quickest of the day so far. The Australian clocks a 1:45.3.

  102. 0830: 

    Adrian Sutil sets the first timed lap of the day, a 1:53.7, before slicing three seconds off that on his next lap in the Sauber. The best dry time of the week is a 1:23.2, for reference.

  103.  

    Caterham: So that's our first lap of day four done. @kamui_kobayashi is back in the garage & letting Race Engineer Tim Wright know how the install was.

    Eddie Irvine v 7ft shark
    Eddie Irvine

    Forgive me, but I just want to leave the testing in Jerez briefly and bring you a bizarre story about a former F1 driver who has been battling a 7ft shark.

    Eddie Irvine, who was a contender for the world title in 1999 with Ferrari, came face-to-face with a lemon shark while swimming and spear fishing for dinner near his Bahamas home.

    The 48-year-old said he hit the shark "somewhere on the nose" before swimming to safety. He was unhurt. You can read more about it on our news pages.

  105.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "Daniel Ricciardo is known for being the smiliest man in F1 - if not the world, for that matter - so unsurprisingly he was putting a brave face on Red Bull's problems. 'Even if (Friday) doesn't go to plan, we still won't be worried,' the Australian said. '(The two tests in) Bahrain will sort itself out for us. We have two weeks there, which is good. But we're definitely not getting worried.'

    "However, it was something else he said that underlined the potential seriousness of the trouble Red Bull are in: 'Time is still on our side. Even if we go to Melbourne still a bit whatever, it's a long season. These guys know how to win and I'm sure sooner rather than later we are going to get it together. It's still early days.'"

  106. 0815: 

    Red Bull have made it out - with Daniel Ricciardo managing to drive all the way round the lap and make it back to the garage without any problems.

  107. 0810: 

    Full wet tyres are the order of the day, with Adrian Sutil and Felipe Massa among the first cars out on track. Fernando Alonso heads out in the Ferrari, just ahead of Nico Rosberg. The quartet all complete installation laps before heading straight back in.

  108. 0806: 
    Driver line up for day four

    Daniel Ricciardo will aim to get into double figures today for Red Bull while Nico Rosberg is on duty at Mercedes. Fernando Alonso gets his second run in the new Ferrari while Kevin Magnussen, who impressed yesterday, in action for McLaren.

    Force India's new reserve driver Daniel Juncadella, Sauber's Adrian Sutil, Toro Rosso's Daniil Kvyat, Williams' Felipe Massa, Marussia's Jules Bianchi will also hit the track while Kamui Kobayashi, who had a year out, will get his first taste of the Caterham.

  109.   
    BBC Sport’s chief F1 writer Andrew Benson:

    "All eyes will be on Red Bull on this final day of the first pre-season test. The world champions have managed just 13 laps over three days and there is clearly some kind of major problem going on with their car, which seems to be related to the energy-recovery system. Daniel Ricciardo, who is in the car (or not) again on Friday, said the team 'assume it is something that will have to be sorted out at the factory'. But he added that they hoped there would be a 'quicker fix' that would allow some running in Jerez."

  110. 0803: 

    Morning all and welcome and to our live text commentary of the final day of the first pre-season test at Jerez. It's a pretty miserable day in southern Spain, with overnight rain continuing on into this morning. That means it's wet, very wet, out on track.

  111. 0800: 
    Daniel Ricciardo

    Beware the wounded (Red) Bull. The narrative of the first three days of testing hasn't been headline times or impressive performances. Oh no. It's been the frustrating start to 2014 for Red Bull, who have managed just 13 - yes 13 - laps across three days of testing.

    But they're reigning world champions - four times no less - and will revel, rather than panic, in their current situation. Complete a bunch of laps today and the misery of the last 72 hours will quickly be forgotten...
