As it happened

  1. 1610: 

    So concludes a the first day of pre-season testing for the 2014 Formula 1 season, with 93 laps completed by the field. Kimi Raikkonen, had a strong day, accounting for 31 of those laps.

    Have a catch-up on everything that happened at Jerez by heading to the F1 pages and join us again 0800 GMT tomorrow for more. Until then, it's good afternoon from me. Adios.

  2. 1607: 
    Lap times

    1 Kimi Raikkonen (Ferrari) 1:27.104

    2 Lewis Hamilton (Mercedes) 1:27.820

    3 Valtteri Bottas (Williams) 1:30.082

    4 Sergio Perez (Force India) 1:33.161

    5 Jean-Eric Vergne (Toro Rosso) 1:36.530

  3. 1603: 

    Sergio Perez goes fourth quickest for Force India as he clocks 1:33.161 just before the chequered flag is wave. That is our lot for day one of testing.

  4.  

    Williams F1: For those asking, this is our testing livery only. We'll launch our race livery ahead of Australia.

  5.

    Kirk Hughes: Rather than award double points why not offer a bonus point for pole position and one for fastest lap of the race.

  6. 1556: 

    The Williams of Valtteri Bottas emerges on to the circuit and clocks 1:30.072 with its first complete lap - the third fastest time of the day. Sergio Perez is back out for one final run.

  7. 1549: 

    Huzzah! Our first sighting of reigning world champ Sebastian Vettel, who decides to give the Red Bull its first run in these last 15 minutes or so.

  8.  

    WilliamsF1: Rain easing off and we are still aiming to get a timed lap in today.

    Force India: Back to the track! Sergio leaves the garage and heads out for some more lappage. Getting to know the VJM07 a little more each time!

    That's the spirit people!

  9. 1546: 

    Hmm, I might have spoken too soon as the rain eases off a bit and one or two teams are mulling over whether it is worth another rumble around the circuit.

  10.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Mercedes co-team boss Toto Wolff has said the sport should look again at the controversial new rule that awards double points at the final race of the season. 'Was it the right move or not? 99% of the fans say it is the wrong move so perhaps it is something we have to revisit,' Wolff said. 'Everything is possible. We had another meeting and decided to keep it for the moment, and discussions are ongoing. If we see the same power situation with one team dominating, it adds some spice. Obviously there is a lot to criticise but when you see audiences dropping you need to try out things. This maybe wasn't the right thing but we need to find out.'

    "Driver Nico Rosberg was even more outspoken: 'I'm sorry to say but it's no good. But that's the way it is. But then if you get to the last race and because of this new points system it remains exciting I'm sure all the spectators will be sitting in front of the TV and will be excited and happy about it. Now we're all sitting here saying it sucks but maybe by the last race it keeps things exciting.'"

  11. 1541: 

    It looks like we have seen all we will see for today as rain starts to fall shortly after Kimi Raikkonen popped back in. His fastest time of 1:27.104 looks like it will be unchallenged. This gives us time to grab a few more words from our chief F1 writer Andrew Benson before a little look at what we have in store on Wednesday...

  12. 1536:  
    BBC F1 pit-lane reporter Lee McKenzie:

    Spoke to Lewis Hamilton who is pretty excited with the achievements of his Mercedes team despite that front wing failure this morning.

  13. 1534: 
    Kimi Raikkonen

    Kimi Raikkonen is round in 1:27.9 on his 30th lap before heading back in and silence descends on Jerez, with the circuit empty.

  14.  
    Get involved- #bbcf1

    Jack Goward: Actually like what @CaterhamF1 have done with the nose on their new car. Something a bit different.

  15. 1522: 

    Back out comes Kimi Raikkonen in the Ferrari. The Finn is currently fastest and has completed the most laps at 24.

  16.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Lotus may not be in Jerez, but there has been plenty of talk about their innovative 'crab' nose, which features two prongs rather than the single proboscis seen on many of the cars. On Monday, Toro Rosso technical director James Key said he felt it might not be within the spirit of the rules, but Lotus have issued a statement quoting technical director Nick Chester dismissing any concerns.

    "'We have passed all the necessary crash tests and are very confident our design complies with all the FIA legal requirements,' Chester said. 'We have just taken an innovative direction and one that's different to the other teams. Where there are so many variations in design, there is always bound to be a little talk, but we remain relaxed and focused on our design and progression.'"

  17.  

    Force India: Two-lap run for Checo, who returns to the pits for more checks. Runs like these are vital for opening testing sessions

  18. 1510: 
    Williams' Senna logo

    The Williams retains Ayrton Senna's logo on the side of the FW36's nose ahead of a season which marks 20 years since the Brazilian lost his life in a crash at the San Marino Grand Prix at Imola.

  19.  

    Caterham driver Marcus Ericsson: Just done my first lap as a @CaterhamF1 driver. Very proud moment! Initial feeling good, but now the hard work starts.

  20.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Sebastian Vettel, who is still sitting around waiting to go out in his new car, has also been talking about his concerns for Michael Schumacher. The world champion admitted it was worrying that " he is still in a coma and we still don't know what shape he will be in when he wakes up". You can read more from Vettel on Schumacher here."

  21. 1500: 
    Williams

    With just one hour to go, Williams have tweeted a picture of their new car, which is about to leave the garage with Valtteri Bottas at the wheel. "The atmosphere in the garage is electric," tweeted the team.

  22. 1453: 
    Kimi Raikkonen

    Kimi Raikkonen is back out in the Ferrari and instantly gets down to business, setting a personal best on his first lap out and then going fastest of all with a 1:27.4. Next time round, the Finn goes quicker again, improving to a 1:27.1.

  23. 1446: 
    Testing update

    If any of you are just joining us, Lewis Hamilton has been the story today, first setting the leading time before crashing and ending the day's running.

    The crash was caused by a front wing failure, but the Briton still clocked up 18 laps - more than anyone else so far - and seemed reasonably happy with his day's work.

    Kimi Raikkonen is second quickest, 1.6 seconds off the pace, with Jean-Eric Vergne and Esteban Gutierrez the only two other drivers to have set a lap time.

    Sergio Perez and Marcus Ericsson have popped out for installation laps, but we've still not seen the Williams, McLaren or Red Bull yet.

  24. 1442: 
    GO! GO! GO!

    The Toro Rosso has been cleared and we're back under way....

  25. 1436: 
    RED FLAG

    Out comes the red flag, as Jean-Eric Vergne grinds to a halt out on track...

  26. 1430: 

    Mercedes executive director Toto Wolff said that there were a number of little problems that had to be fixed throughout the morning. He added that they were nothing serious but to be expected with such a complex new car.

  27.  

    Mercedes driver Lewis Hamilton: Incredibly positive start today! I'm really proud of the team for what they've achieved in getting us here!

  28. 1425: 

    Who is Marcus Ericsson? Well he's a 23-year-old Swedish rookie F1 driver, who finished sixth in the GP2 feeder series last year, winning one race. He won the Formula BMW UK championship in 2007 and the the Japanese F3 title in 2009. He lines up alongside Kamui Kobayashi at Caterham this season.

  29. 1420: 

    So Marcus Ericsson is putting some mileage on the Caterham, but he's yet to complete a timed lap. Kimi Raikkonen, meanwhile, is really motoring, upping his lap count to 14, just four fewer than Lewis Hamilton managed before a crash ended his running.

  30.  
    Get involved- #bbcf1

    Will Strutt: Starting to get excited for the new F1 season. Backing Kimi all the way again this year, time to put Alonso in his place!

  31. 1410: 

    Mercedes confirm that it was a front wing failure that caused Lewis Hamilton's crash. Here's what the Briton, in his second year with the team, had to say: "For me it's an incredibly positive start to be the first car out on track and completing a good number of laps.

    "Other teams have been going out for single-lap runs, starting a few hours after we had first hit the track, so to have started running through our test programme was very encouraging.

    "The car feels quite good, especially considering it's so early in our programme, so overall it's been a positive day. Of course, it's unfortunate to end the day early when everyone has worked so hard and we had looked like easily completing the most mileage of anyone here today, but we'll make that track time back and it's better to have these things happen now than in Melbourne."

  32. 1400: 
    Caterham

    And here's the new Caterham, with it's own interpretation of the nose rules, courtesy of driver Kamui Kobayashi.

  33.  

    Sauber driver Adrian Sutil: I'm excited to hit the track with the #C33 for the first time!It has been a pleasure working together with the great @OfficialSF1Team so far.

    Sutil, who raced for Force India last season, will be in action at Jerez on Thursday and Friday

  34. 1350: 

    And it seems Williams are almost ready to go at last, too. "Car has fired up and is now being set up ready to run," tweeted the team. "We are hoping to show you the #FW36 soon!"

  35. 1345: 
    Caterham fire up their car

    Here's a first glimpse of the new Caterham as the team fire up their car. Rookie Marcus Ericsson will be the first to get behind the wheel. Kamui Kobayashi will get his shot later this week.

  36. 1340: 

    Mercedes say they will not be heading out again today, with Lewis Hamilton, Nico Rosberg and executive director (business) Toto Wolff set to talk to the media in just over 20 minutes.

  37. 1333: 

    Jean-Eric Vergne has the track to himself but he soon peels back into the pits. The focus now is on the Caterham garage as we've yet to see what their 2014 challenger looks like. We're expecting them out shortly.

  38. 1323: 

    It won't be long until we see the new Caterham for the first time as the team tweet that rookie Marcus Ericsson is in his overalls and having a briefing with the engineers ahead of his first run.

  39. 1320: 

    Max Chilton tweets that he is on his way to Stanstead to catch a flight to Jerez. The Marussia driver was supposed to be driving today, but the team had some issues with the car and only sent it on its way to Jerez this morning. They are expected to start running on Thursday.

  40. 1310: 
    Lewis Hamilton

    Here's a shot of Lewis Hamilton's damaged Mercedes, after a failure - thought to be the front wing - sent the Briton into the barriers earlier in the session.

  41.   
    BBC F1 pit-lane reporter Lee McKenzie:

    "Red Bull have not run their new car so far today, and Adrian Newey said this was down to a 'silly' problem with the car overnight. But they said they do still intend to run this afternoon."

  42. 1300: 

    It's all quite out on track at Jerez, with three hours of the session remaining.

  43.   
    BBC Sport's chief F1 writer Andrew Benson:

    "A reminder of the main focus of this test for most of the teams came from Toro Rosso technical director James Key, who described the new car as a "platform to run the power-unit" with lots more developments to come in terms of performance. "This isn't a performance week for us, it's a reliability week". He added that he expected "a lot of red flags" stopping running as teams hit trouble."

  44. 1250: 

    Kimi Raikkonen is doing a few laps in succession out there, improve to a high 1m32, then a mid-1m30 and finally a mid-1m29. That's still around 1.6 seconds off the pace set by Lewis Hamilton before his off.

  45.  

    Caterham: Lunch is done (burgers, couple of salads, pasta or rather nice Asian salmon for you foodies out there) & we're nearing "fire up & go" time...

  46. 1239: 

    Kimi Raikkonen becomes the third driver to set a timed lap, the Finn clocking a 1:33.131 which is good enough for the second fastest time of the day. The 2007 world champion then completes his in-lap before peeling back into the pits.

  47. 1231: 

    Pirelli say they will do rain-tyre testing on Friday, using water trucks to soak the track, so they can gather data for rain-hit races this season.

    But if it rains tomorrow or Thursday then the plan will be scrubbed.

    The full wet tyre has a new rear tread pattern which is aimed at reducing aquaplaning by increasing how much water can be dispersed at full speed - up to 65 litres per second from 60 litres per second previously.

  48. 1225: 

    Speaking at the unveiling of the new Mercedes W05 this morning, Lewis Hamilton said of his new car: "It looks just fantastic, so aggressive but full of really nice details as well."

    Hamilton, who won the title in 2008, added: I think this is probably the season with the most unknowns that I have faced in my career and that's just so exciting for all of us.

    "This is my second season with Mercedes and it now feels like I am a fully-fledged member of the team and that we are nurturing the great relationship we built last year."

  49. 1221: 

    Here's the story on Lewis Hamilton's crash. Eye-witnesses say they saw the front wing come off the car before the Mercedes driver lost control.

  50. 1216: 

    Veteran F1 journalist Dan Knutson: "Nobody can remember a day of testing like this - a juxtaposition of incredibly busy yet very quiet. The mechanics are thrashing away in the garages on the cars. There has been a huge media turnout at the car unveilings this morning and at the Red Bull team press conferences during the day. The media centre is packed. Yet the pits, paddock and track are all very quiet, with just the occasional car turning a lap now and then."

  51. 1212: 
    Kimi Raikkonen

    Kimi Raikkonen heads out on track, but it's just the one lap for the Finn as he peels back in without crossing the start-finish line. It is, however, an excellent opportunity to show you a picture of Raikkonen in action in his shiny new Ferrari. The more I look at the Ferrari, the better it looks.

  52. 1206: 
    Esteban Gutierrez

    Only Lewis Hamilton and Jean-Eric Vergne have completed flying laps today, with Kimi Raikkonen, Esteban Gutierrez (pictured) and Sergio Perez just doing installation laps.

  53. 1200: 

    No one seems too keen to head out on track after Lewis Hamilton's off. Maybe they're taking an early lunch...

  54. 1155: 
    GO! GO! GO!

    The marshals have done a super job to clear up all the debris and we've now got green flags waving at Jerez.

  55. 1150: 

    The whole front end of the Mercedes has been ripped off. Hamilton is out of the car and the team report that it was a car failure which led to the off. "Cause to be investigated once the car returns to the garage," says the team.

  56. 1147: 
    CRASH!

    It's Lewis Hamilton. The Mercedes driver has crashed into the barriers at Turn One.

  57. 1145: 
    RED FLAG

    We've got our third red flag of the day and this time it looks like we've got a car in the barriers...

  58. 1143: 

    Lewis Hamilton is back out on track, along with Esteban Gutierrez, and the Mercedes driver improves on his previous best by about two seconds, clocking a mid-1:27.

  59.   
    BBC Sport's chief F1 writer Andrew Benson:

    "There has understandably been a lot of focus on the design of the cars' noses this season, and on Monday Toro Rosso team boss Franz Tost said they should be got rid of for 2015. But his driver Jean-Eric Vergne had another view, in pointing out the reason they have ended up that way: "It was a bit of a surprise for everyone but it is the same whenever there are new regulations - everyone will get used to it after six months. If this can improve the safety, everyone will think it is a good thing for F1."

  60. 1130: 

    If you're wondering where Red Bull or indeed McLaren, Williams and Caterham are, they are present in Jerez, but have so far failed to leave their garages. Lotus aren't attending the test at all, while Marussia are on their way, after solving last-minute technical issues with the car.

  61. 1125: 

    So far, Lewis Hamilton has completed the most laps at 14, with Jean-Eric Vergne second on 11. Kimi Raikkonen has managed just two, while Sergio Perez and Esteban Gutierrez are on one apiece.

  62. 1115: 
    Lewis Hamilton

    Mercedes' Lewis Hamilton breaks the silence, completes a three-lap run and then heads back to the pits without improving on his time.

  63.   
    BBC F1 pit-lane reporter Lee McKenzie:

    "At Red Bull's media event this morning, chief technical officer Adrian Newey said this test would be all about system checks and so on, and that seeking performance would only begin at the first Bahrain test next month. Meanwhile, it is pretty quiet out on the track. In fact, it's almost peaceful, with sunny skies and just the occasional car droning around."

  64.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Toro Rosso driver Jean-Eric Vergne was passed over for the Red Bull drive alongside Sebastian Vettel in favour of former team-mate Daniel Ricciardo. The Frenchman says he has been working on the weaknesses he believes that were in his driving that led to the decision.

    "'I have changed many things. I am a good driver otherwise I wouldn't be here but there many things I needed to work on myself, especially in the head. I am quick, I have shown it many times, it is just a question of putting everything together when the pressure is there. I have worked a lot this winter on this and we will see the results in the first part of the season.'"

  65. 1103: 

    Lewis Hamilton and Jean-Eric Vergne are doing all the running at the minute, with Hamilton dipping down to a 1:29.662 as he ups his tally to 10 laps. Vergne does a run of five laps, with a best of 1:36.530 before heading back to the Toro Rosso garage.

  66. 1058: 

    The problems at Caterham continue....

    "It's nearly noon in Jerez & work continues in our garage," tweeted the team. "Not surprisingly for a totally new car, we're unearthing new issues every time we take a step forwards, but that's what testing's for! And, even though it's still only day one on track, it's actually day two for the mechanics and day three for the truckies."

  67. 1055: 
    Kimi Raikkonen

    Tomorrow marks one month since Michael Schumacher's skiing accident. The German seven-time world champion remains in a critical but stable condition in a medically-induced coma. Ferrari have displayed the message #ForzaMichael on their car while Mercedes are running the message #KeepFightingMichael.

  68.  
    Get involved

    Jack Hannaford: Expect to see Vettel's dominance cut a bit by lack of exhaust tech. His style suited that perfectly, could take him a while to adapt.

    Chintan Patel: Alonso & Kimi have been in the sport too long to fight at Ferrari. Both have tons of experience and maturity for anything to go wrong.

    Ian McCormack: Would love to see another team "do a Brawn" - Willams and Sauber deserve some good results for sheer perseverance in recent seasons.

  69. 1050: 

    Jean-Eric Vergne becomes the second driver to set a timed lap, the Frenchman clocking an uninspiring 1:43.299, which is nearly 10 seconds slower than Lewis Hamilton's effort.

  70. 1045: 
    Testing update
    Lewis Hamilton

    Hello to anyone who is just joining us on this first day of pre-season testing for the 2014 Formula 1 season.

    Lewis Hamilton has been the busiest driver in Jerez, clocking up seven laps. However, the Mercedes driver has set just one timed lap and is the only man to have done so.

    Jean-Eric Vergne, Kimi Raikkonen, Sergio Perez and Esteban Gutierrez have all ventured out on track, with Raikkonen and Perez rolling to a stop and requiring a lift back to the pits from the marshals.

    Lotus are missing this test, while Marussia are expected to start running on Thursday. McLaren, Red Bull, Williams and Caterham have yet to head out of their garages.

  71. 1035: 

    Kimi Raikkonen heads out for another attempt at completing a lap and this time he manages it. The Finn, who stopped out on track early in the session, cruises round at Jerez to carry out a number of system checks before peeling back into the pits.

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

    "The new cars and engines, and how teams cope with them, form the fundamental fabric of the season. But there are so many other narratives, of which only the very first clues will appear before the season starts in Melbourne.

    "Can Red Bull-Renault continue their domination, despite the major rule changes? How will Daniel Ricciardo shape up against world champion Sebastian Vettel? Can Lewis Hamilton, whose outright speed is not in question, adapt his driving to the complexities of the new F1?

    "How will Fernando Alonso and Kimi Raikkonen get on at Ferrari? Can McLaren recover some self-respect after a disastrous 2013; and how will Kevin Magnussen compare with team-mate Jenson Button? All this and more promises to make 2014 a fascinating season."

  74. 1029: 

    Lewis Hamilton has peeled into the pits after a three-lap run. As yet, we've not seen the Red Bull, McLaren, Williams, Caterham or Marussia. Esteban Gutierrez and Jean-Eric Vergne have headed back to the pits without completing a timed lap.

  75.  

    Williams: The last of the night shift have just headed back to the hotel for some well earned sleep and the day shift continue to work on the #FW36.

    We've still not seen the new Williams in the flesh yet.

  76. 1023: 

    Lewis Hamilton clocks a 1:33.305. It doesn't really mean anything, but it's still a timed lap and the first of 2014.

  77. 1021: 

    The track is heaving as Jean-Eric Vergne makes it three cars out on the circuit in the Toro Rosso. Lewis Hamilton, meanwhile, has crossed the line to start a timed lap! At last. Just a 140-minute wait....

  78. 1020: 

    Sauber becomes the fourth car to take to the track, with Esteban Gutierrez at the wheel. The Mexican secured a second year at the Swiss team after a decent rookie season. He's got Adrian Sutil for company this year.

  79. 1015: 
    GO! GO! GO!
    Lewis Hamilton

    The marshals have successfully removed the stricken Force India from the track and we're back under way. Lewis Hamilton is the first man out...

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

    "One of the joys/frustrations of pre-season testing is trying to cut through the fog of obfuscation and masses of data to try to glean some meaningful information about how the teams compare performance-wise. This is likely to be even more difficult this year than it already was.

    "The introduction of a fuel limit, and the need to ensure cars perform economically enough to finish the race on the maximum 100kg of fuel, means it will be almost impossible to read anything into the lap times.

    "Whether a time, or a run, was set at a pace that complies with the regulations will be impossible to define, and it simply adds a further level of difficulty on top of the other intangibles such as how much fuel was on board, what tyres were being run, how the car was being set-up, what the team were working on, and so on."

    Robb Meehan: Has the recovery truck at Jerez had the most test KM's thus far?

  82. 1003: 
    RED FLAG

    Sergio Perez's first run for Force India doesn't last long, though, as the Mexican grinds to a halt after just a few corners. Out comes the recovery truck...

  83.  

    Force India: And off we go! The VJM07 and @SChecoPerez are on track!

  84. 0959: 

    Daniel Ricciardo's former team-mate Jean-Eric Vergne becomes the third man out on track, as he takes his Toro Rosso out for a spin. But like Lewis Hamilton, the Frenchman peels back into the pits after a single lap.

  85.   
    BBC Sport's chief F1 writer Andrew Benson:

    "The helmet of new Red Bull driver Daniel Ricciardo features a painting of a honey badger. He has explained why he identifies with it: 'It's an animal I discovered a few years ago. It's known to be probably the most fearless animal in the animal kingdom. You look at it and in some pictures it looks quite cute and cuddly and it seems pretty laid back but as soon as it wants something or someone crosses his territory in a way he doesn't like, he turns into a bit of a savage. He'll go after anything - lions, pythons - so he turns very quickly but he's a good guy.'"

  86. 0957: 

    You rarely see Daniel Ricciardo not smiling and today's no different. The Australian, who won't get his hands on the new Red Bull until Thursday, was bullish about his hopes of challenging world champion Sebastian Vettel this season after signing a deal to join the team. However, while his enthusiasm for the challenge remains, he has toned down his expectations now he is in Jerez.

    "I'm really excited to be alongside Seb this year," said the former Toro Rosso driver. "He has achieved so much in so little time. To be a four-time world champion, no matter what the circumstances, is an amazing thing.

    "I have a lot of respect for that and a lot of respect for him. I am just really looking forward to learning as much as I can and hopefully challenging him. Of course, I want to try to get some success. But to do that first of all I have to respect him and then go forward from there."

  87. 0950: 

    Lewis Hamilton heads out for the fourth time today, but as per his other three appearances, the Mercedes driver peels straight back in rather than crossing the start finish line to start a timed lap.

  88. 0945: 

    For some teams, today will not be the first time they have run their cars. Last week, Mercedes and Force India used one of their allocated filming days for promotional material to give their new cars a shakedown at Silverstone. Toro Rosso did the same thing at Misano in Italy. They are limited to 40km and must use demonstration tyres.

  89.   
    BBC Sport's chief F1 writer Andrew Benson:
    Lotus

    "Lotus may not be at this test, but their new car - of which a single image has been released - has been attracting attention, and not all of it welcome. Amid the flurry of 'anteater' noses - and some ribald phallic references to Toro Rosso's - the Italian team's technical director James Key questioned whether the double-pronged approach Lotus have taken with their nose was within the spirit of a set of rules aimed at making cars safer in various kinds of accidents.

    "'We kind of understand where they've gone with it,' Key said. 'It could be worth a re-visit when things have calmed down. I don't think it's illegal, it just whether it's in the spirit of the regulations. Our interpretation of a similar idea was slightly different at the front of the nose to the point where we were happy it could be accepted as within the spirit of the regs. The Lotus is probably the most extreme out there, I would think.'"

  90. 0938: 

    We've still not seen world champion Sebastian Vettel in action in the new RB10 - but he is talking about his new car.

    "The car looks very different - especially underneath," said the German. "There is a lot going on. The technology behind it is really complex. For all the engineers it is very difficult to understand everything because everything is linked. For the drivers, it is even harder because we haven't been to school for so long - but it's fascinating."

    The German usually gives a name to his car, but I'm not sure if he's come up for one for this one yet.

    BBC Sport's chief F1 writer Andrew Benson:

    "The clean lines of the new Red Bull have served as a reminder of the potency of this incredible team, but Sebastian Vettel is playing down the chances of winning a fifth consecutive title and emulating Michael Schumacher and Ferrari's achievement a decade ago.

    "'Everything is possible,' Vettel said. 'We are on an incredible run, winning the last four in a row. Obviously we try to do it again to make it five just like Michael did but at the moment the expectations are fairly low because we don't know what's coming. Now it is a complete blank sheet of paper so we have to wait and see, the first couple of races see where we are, see how big the trouble is for us and the others and then we go from there.'"

  92. 0931: 
    Kimi Raikkonen

    Fancy seeing a shot of Kimi Raikkonen - one of only two drivers who have made it out on track today in their 2014 machines? Well here you go!

  93. 0926: 

    It seems Caterham are still in a spot of bother. "Work continues in the garage to prepare for our first run of 2014," the team tweeted. "We still can't say when that'll be but we're definitely aiming for today."

    It's not ideal considering owner Tony Fernandes has threatened to quit at the end of the season if results do not improve. The team have failed to score a point in 77 races since their debut in 2010.

    Neil: I think the Toro Rosso is the best looking. Shame Lotus aren't in Jerez to showcase the double pronged nose.

    Ryan Williams Hayes: Some start for Ferrari and Kimi this year with the car breaking down after only a handful of corners.

    Alex Crutchley: As usual, the RBR looks like a rainbow threw up on it. The Ferrari (and to a lesser extent, the Mercedes) looks like a vacuum cleaner.

  95.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Not only do Lotus not have a car at this test but they have also lost team principal Eric Boullier, who is moving to the same role at McLaren. He will replace Martin Whitmarsh following the boardroom coup that has seen chairman Ron Dennis put back in charge of the F1 team. Boullier is not expected to be in Jerez with McLaren, but the announcement of his new role is only a matter of time."

  96. 0918: 
    Lewis Hamilton

    We've not had a single timed lap yet at Jerez, I'm afraid, with only Lewis Hamilton and Kimi Raikkonen brave enough to head out on track. As I type, Mercedes have just fired up their car once more, with the Briton, sporting a new haircut, set to hit the track for the third time.

  97. 0912: 

    Good news for Marussia fans and, indeed, their drivers Max Chilton and Jules Bianchi. The team report that the car is now on its way to Jerez. "Well done team for resolving the issue," Marussia tweet. "Our garage awaits you."

  98.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Inevitably, there has been much talk about the noses on the new cars. It's fair to say Red Bull chief technical officer Adrian Newey is not a fan either. 'It's been deemed that it's safer,' Newey said, 'although whether it will make much difference in stopping a car launching if it runs into the back of another is a moot point. It's a funny regulation.

    "'It calls for a maximum side-view height, and then on top of that there is an area 50mm behind the front of the nose which we have to meet and that area is quite low down, much lower than the side view, so you end up with almost two noses, one which is the main bulk of the nose which is this minimum side-view height and then almost a bulb sticking out from that to satisfy the area rule much lower down.

    "'To varying degrees I would imagine everybody will have these rather ugly and ungainly noses which I think is an awful shame - to me the aesthetics of an F1 car are important. They should look good and not many of the owners of these noses could really love them.'"

  99. 0905: 
    GO! GO! GO!

    Kimi Raikkonen's Ferrari has been loaded onto the back of a truck and is winging its way back to the pits. The track is now clear, so it's go, go, go again.

  100. 0900: 

    Brace yourself, folks - I've got some tyre chat for you. Pirelli have brought winter tyres to Jerez, for use in this test only, to ensure teams get as much track time as possible if the weather turns cold.

  101.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Don't expect too many stunning lap times on this first day of running - or even for the rest of the week. This is called testing for a reason. The teams will spend the first day making sure their cars work, and then the rest of the test running through basic set-up programmes to see how they respond to changes. And the complexity and novelty of this year's cars means the teams will generally be focusing on practicalities rather than performance."

  102. 0852: 
    Force India

    Once Mercedes and Red Bull had pulled the covers off their respective new machines, it was the turn of Force India, with Nico Hulkenberg and Sergio Perez doing the honours.

  103.  

    Ferrari: #F14T out but not in. Precautionary stop by engineers, now checking. Car on its way back to the pits...

  104. 0845: 
    RED FLAG

    We have our first red flag of the day, just 45 minutes into the session. Kimi Raikkonen is the culprit, the Finn driver firing up his Ferrari and heading out on track only to pull over after a handful of corners.

  105.  

    Williams: For those waiting to see the #FW36 you will have to wait a short while longer but I promise you we'll have her on track as soon as we can!

  106. 0840: 

    Lewis Hamilton has headed back out on track in his Mercedes, with the number 44 on his car. Drivers have been allowed to choose their own numbers which will stay with them for the rest of their careers.

    Hamilton has chosen #44, his old karting number. Sebastian Vettel will run with the #1 as he's world champion - but should he not defend his title this year, he'll switch to the #5 for next season.

  107.  

    Lotus driver Romain Grosjean: Watching pictures from Jerez! Always exciting to discover new cars, new helmet designs.

  108.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Apart from Marussia, there is one major absentee from this test - Lotus, who ended last season with the second quickest car. They have not managed to get their 2014 car ready in time for Jerez, and will instead run for the first time in Bahrain next month. Senior figures admit they have some concerns about the situation that puts them in, in terms of readiness for the start of the season."

  109.  
    Get involved

    Luke John Cassar: The Ferrari looks good as well. I did not like the shape of the that pointed nose on the RBR 10. Good morning from Malta.

    David Hird: If a fast car looks good. Red Bull and Merc at the front. The force India and Toro Rosso will be in the GP3 field.

    Thomas Casson: The RB10 is by far the best looking car with the protruding nose, especially in carbon fibre.

  110. 0830: 

    So it looks like it's going to be a tricky opening day for a number of teams at a dry Jerez, where temperatures are hovering around the 13ºC mark.

  111.   
    BBC F1 pit-lane reporter Lee McKenzie:

    "As we already know, Marussia don't have a car here yet and Caterham are unlikely to run today. But it seems the difficulties preparing the new cars may extend to the front of the grid. There are rumours one of the top teams will also not run today, and I hear another may not have been able to start an engine when they tried this morning. I'll keep you posted."

  112.   
    BBC Sport's chief F1 writer Andrew Benson:

    "The Caterham is still being built in the garage. The team is aiming to get it together enough for photos later today, but it probably won't run until Wednesday. Marussia are now planning to get the car here Wednesday night and run it Thursday."

  113.  

    Red Bull driver Daniel Ricciardo: Car looks like a hot rod! It's got swag. Pumped!

  114. 0825: 
    Red Bull

    Red Bull are known for their secrecy and old habits die hard. They unveiled their new RB10 at 0838 local time, revealing its unusual nose with strange blob on the tip, which seems to be some sort of airflow splitter. Three minutes later, the mechanics had put the covers back on the car!

  115. 0822: 

    Kimi Raikkonen will be the first man to get behind the wheel of the Ferrari, with the Finn in action on day one along with eight other drivers. Here's who we can expect to see in action today:

    Red Bull: Sebastian Vettel Mercedes: Lewis Hamilton Ferrari: Kimi Raikkonen McLaren: Jenson Button Force India: Sergio Perez Sauber: Esteban Gutierrez Toro Rosso: Jean-Eric Vergne Williams: Valtteri Bottas

  116.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Lowly Marussia have suffered a blow even before testing has started. The team have encountered a problem with their new car while building it in the factory, and that has meant it has not yet been shipped to Spain.

    "Marussia's mechanics and engineers are in Jerez and the team still plan to run this week, but it is not yet clear when - or if - the car will leave the factory. Given the travelling time from Banbury to south-west Spain, they realistically have to get it sorted within the next 24 hours or so to make it worth trying to get the car to the test."

  117. 0818: 
    Get involved
    New Red Bull

    No one else has been out since Lewis Hamilton popped out for one lap in the Mercedes, so that gives us time to check out the RB10, which broke cover in the Jerez pit lane this morning. What do you think? Tweet us your thoughts on the Red Bull and all the other new cars using the #bbcf1 hashtag or text 81111 (UK only).

  118. 0814: 
    Mercedes

    This has been the year of low-key car launches, with most teams doing an online reveal - such as McLaren, Ferrari and Sauber - or simply pulling the covers off in the Jerez pit lane. Mercedes did just that earlier this morning - and here it is, the W05. Definitely one of the more aesthetically pleasing of the 2014 cars so far...

  119.   
    BBC F1 pit-lane reporter Lee McKenzie:

    "We've had our first taste of the new sound of Formula 1. The Mercedes has done one lap in Lewis Hamilton's hands and the new turbo engine had a very different pitch from the old 2.6-litre V8s. Admittedly, the car was nowhere near the limit, but the engine was not as loud, and has a much lower growl to it, and does not get to that shrill, ear-piercing wail that they used to. Initially, it sounds weird - but that's almost certainly just unfamiliarity."

  120. 0812: 
    GO! GO! GO!

    The action is already under way - with Lewis Hamilton the first man to take to the track. Formula 1 2014 is officially go, go, go.

  121. 0810: 

    So we've got three tests before the season starts in Melbourne on 16 March.

    Each lasts four days and will give the teams an opportunity to put their cars through a rigorous shakedown.

    Teams can only use one car and one driver per day, so ultimately, each driver will get around six full days of testing.

  122.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Most of the F1 cars have been seen already one way or another - Ferrari, McLaren, Lotus, Williams, Force India and Sauber have all at least released computer-generated images of their challengers. But this morning sees two of the most important cars of the season break cover - world champions Red Bull and runners-up Mercedes both unveil their new cars at Jerez before getting down to running."

    Images of those two cars to follow shortly.

  123. 0807: 

    In terms of aerodynamics, the cars will look visibly different, as you'll see in this live text throughout the day as I pepper it with pictures of the new machines.

    Some chassis changes have been introduced for safety reasons and to slow cars down. The most visual change is the front nose, which is 365mm lower to improve safety, with a real mix of interpretations spread across the teams.

  124.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Giving the new Formula 1 cars their first runout this morning is the culmination of months, even years, of work. The new turbo engines and aerodynamic rules being introduced this year amount to the biggest rule change in a generation and all the teams are predicting that reliability will be a major problem this week - and into the start of the season. Expect plenty of breaks in the programme to recover cars stranded out on track."

  125. 0804: 

    There are stacks of changes to go through for this season, but rather than go through them now, may I point you to a feature on our F1 pages which you can read at your leisure.

    The good news for the neutral is anything could happen. Christian Horner, the Red Bull team boss, believes power unit failure rates in races could be as high as 50%, yes 50%!

    The likes of Marussia and Caterham have never had a better chance of scoring their first points.

  126. 0802: 

    It's been years since we've seen changes of this magnitude to the regulations which can only mean one thing - unpredictability. Sure, the big teams will probably still be at the front, and the smaller outfits somewhere near the back, but if were going to see a Brawn-esque shock anytime, it's going to be this year.

  127.   
    BBC Sport's chief F1 writer Andrew Benson:

    "Just two months and four days after the conclusion of the 2013 season, the Formula 1 teams are in Jerez in south-west Spain to start preparing for 2014. The shortest winter break for years is badly timed, for the cars that take to the track in Jerez this week will be more different from their predecessors than perhaps ever before. This activity is called testing - and the word is likely to apply in all its meanings for the teams this week."

  128. 0758: 

    Can you smell that? Yep, it's the scent of petrol fumes emanating from the garages at a dusty race track in southern Spain. The teams are just firing up their brand-spanking new 1.6-litre V6 turbo engines ready to see if months - years even - of hard work has been worth it.

  129. 0755: 

    New cars, new engines, new Kers which is now Ers.

    New fuel limits, new noses and a race that is worth double any other.

    Welcome to Jerez. Welcome to pre-season testing. Welcome to the dawn of a new era for Formula 1.
