  4. 14:03: 

    Kevin Magnussen finishes fastest on the second day of pre-season testing in Bahrain. The McLaren driver set 1:34.910 on the supersofts to top the timesheet for the second time in testing.

  5. 13:57: 

    It looks like Kevin Magnussen is going to finish day two of the second pre-season test fastest as he leads the way heading into the final few minutes. He has certainly made up for lost time, having completed over 30 laps since returning to the circuit this afternoon.

    Andrew, via text: Red Bull have the best car designers and engineers, the last four seasons have shown us that. As a result, they have the best in-season car development with upgrade packages and slight tweaks to the car setup. We saw that at the end of last season with Vettel's nine wins in a row. So it wouldn't be a bad thing if Red Bull were to get off to a slow start to the season, as they will eventually come good.

  7. 13:53: 

    It does not look like Max Chilton is going to get back out in the Marussia before the end of the session and Kamui Kobayashi takes advantage of his inactivity as 1:42.070 moves him above the Briton at the bottom of the timesheet and into 10th.

  8. 13:49: 

    Red Bull: The team's been hard at work today. 10 minutes still to go. Time for another outing before the end of the session.

  9. 13:42: 

    Sebastian Vettel takes the Red Bull back out on the circuit for the final 20 minutes of today's testing.

  10. 13:38: 

    Valtteri Bottas breaks the 100-lap barrier, which will be of great relief to the Williams team after a day of relative inactivity yesterday because of a fuel system problem.

  11. 13:34: 

    F1 journalist Dan Knutson: Sauber, unlike the other teams, didn't bother putting up the screens to hide its car.

  12. 13:31: 
    Latest laps

    1. Valtteri Bottas (Williams) 93 laps

    2. Fernando Alonso (Ferrari) 85

    3. Nico Rosberg (Mercedes) 58

    4. Jean-Eric Vergne (Toro Rosso) 57

    5. Esteban Gutierrez (Sauber) 55

    6. Sebastian Vettel (Red Bull) 49

    7. Nico Hulkenberg (Force India) 45; Kamui Kobayashi (Caterham)

    8. Kevin Magnussen (McLaren) 28

    9. Romain Grosjean (Lotus) 18

    10. Max Chilton (Marussia) 14

  13. 13:24: 

    F1 journalist Dan Knutson: The teams put screens in front of their open garage doors to hide their cars. But Ferrari is taking that a step further by setting up screens to shield the F14 T even when it is in the pitlane.


    After I took this photo a mechanic moved in to block the gap in the screens.

  14. 13:21: 

    Kevin Magnussen briefly returned to the pits but he is back out and ramps it up again with 1:34.910 on the softest Pirelli tyres. Incidentally, the four fastest times so far today have been set by Mercedes-powered cars.

  15. 13:16: 

    Kevin Magnussen's benchmark time was on the soft tyres. McLaren's best time in qualifying for the Bahrain Grand Prix last year was 1:33.702, so Magnussen less than two seconds off that time.

  16. 13:09: 

    And just as I finish typing all that up, Kevin Magnussen goes fastest off all, dipping below 1:36 with 1:35.489.

  17. 13:07: 
    Latest lap times

    1. Nico Hulkenberg (Force India) 1:36.445

    2. Nico Rosberg (Mercedes) 1:36.965

    3. Kevin Magnussen (McLaren) 1:37.078

    4. Valterri Bottas (Williams) 1:37.635

    5. Fernando Alonso (Ferrari) 1:37.700

    6. Sebastian Vettel (Red Bull) 1:40.340

    7. Jean-Eric Vergne (Toro Rosso) 1:40.609

    8. Esteban Gutierrez (Sauber) 1:40.717

    9. Romain Grosjean (Lotus) 1:41.670

    10. Max Chilton (Marussia) 1:42.511

    11. Kamui Kobayashi (Caterham) 1:44.354

  18. 13:02: 

    Everything still appears to be ticking over nicely for Sebastian Vettel in the Red Bull. The world champion has managed 43 untroubled laps as we head into the final hour. His best time of 1:40.340 is almost four seconds off pacesetter Nico Hulkenberg.

    What was the 'intriguing' Lewis Hamilton thing happening at 12:30pm?? Haven't seen anything yet?

    I was pulled in by the initial teasing tweet so it may not be as intriguing as it sounded, but Mercedes are hosting an online Q&A with Lewis Hamilton on their twitter feed. An interesting insight, so worth a look!

  20. 12:54: 

    Kevin Magnussen is back out in the McLaren after spending quite a lot of today in the garage. He is not messing about and records a 1:37.078 to move up to third on the timesheet.

  21. 12:48: 
    Christian Horner

    Jennie Gow has been busy scouring the paddock for Formula 1 figures to speak to and this time she grabs a word with Red Bull team principal Christian Horner.

    Horner gives his views on Bernie Ecclestone winning his F1 damages case, saying: "It's good news for F1 and great news for Bernie. The business needs him at the moment as it's tough times with such a big regulation change. Formula 1 more than ever needs Bernie Ecclestone."

    Horner also said Mercedes look like the favourites for the title but added that "reliability will be an issue" for teams at the first few races.

  22. 12:41: 

    Nico Hulkenberg is flying round the circuit now and clocks his best lap time in Bahrain so far with 1:36.445. Nico Rosberg also dips below 1:37 with 1:36.965.

  23. 12:35: 

    The track is open again as we we enter the final 90 minutes of today's testing.

  24. 12:25: 

    McLaren racing director Eric Boullier: "It is early days and we would like more mileage. If we could we would test every day but that is the wrong debate today. We are pretty happy. We did a very good job yesterday, the car is well balanced, we still have too many glitches as is always the case at this stage. We have to be very patient but so far we can be happy with that."

    Eric not giving too much away then...

  25. 12:24: 

    The Sauber is back in the garage so we should be back under way again shortly. Meanwhile, a few of you have been asking about why McLaren have completed so few laps today - Kevin Magnussen has managed just 11 so far. Jennie Gow managed to catch a word with new racing director Eric Boullier not too long ago, so here is what he had to say...

  26. 12:17: 

    Red flag out for the third time today and those out on the circuit dive back into the pits. Esteban Gutierrez is not among them though as he appears to have stopped out on the track.

  27. 12:14: 

    Nico Hulkenberg's timesheet-leading lap today was set on the soft Pirelli tyre, second fastest Nico Rosberg's on the medium.

  28. 12:09: 
    Jean-Eric Vergne

    Bellys full (as they can be), a few more drivers head back out on to the circuit for the last two hours of testing. Jean-Eric Vergne is among them as he looks to add to the 54 laps he has completed so far.

  29. 12:03: 

    The judge who rejected an £85m damages claim against Formula 1 boss Bernie Ecclestone said he did pay a bribe over a sale of F1 shares.

    Mr Justice Newey, in the High Court in London, said there had been a "corrupt" deal with a German banker to facilitate the sale to a preferred buyer, but he said there had been no financial loss to German media group Constantin Medien, which plans to appeal.

    Read more on the BBC News website.

  30. 12:00: 

    Pacesetter Nico Hulkenberg is on a programme which revolves around set-up work as Force India play around with a variety of settings in the VJM07. He has improved his benchmark time ever so slightly, clocking 1:37.211.

  31. 11:57: 

    With a Mercedes trio leading the way, here is a quick reminder of what engine powers each car on the grid:

    Renault - Red Bull, Toro Rosso, Lotus, Caterham

    Ferrari - Ferrari, Sauber, Marussia

    Mercedes - McLaren, Mercedes, Force India, Williams.

  32. 11:51: 

    Nico Hulkenberg heads out in the Force India and immediately puts 1:37.215 on the board to move top of the timesheet, heading a Mercedes-powered trio that includes Nico Rosberg and Williams' Valtteri Bottas.

  33. 11:46: 
    Eric Boullier

    F1 journalist Dan Knutson: "The BBC's Jenny Gow interviewing McLaren's new racing director Eric Boullier. Earlier, Boullier was spotted having a meeting with Mercedes executive directors Toto Wolff and Paddy Lowe. It would have been nice to have been a fly on the wall for that one to hear what they were talking about."

  34. 11:42: 

    It has been a while since we saw Max Chilton out on the circuit in the Marussia. Chilton managed 14 laps earlier in the day but aside from tweeting his lunch, we have not heard much from him since. IT issues restricted Marussia to just a couple of laps all day yesterday but no word as to whether they are having any problems on day two.

  35. 11:38: 

    Mercedes appear to have resolved the issue that caused Nico Rosberg's second stop earlier in the morning and the German swiftly makes his mark as 1:37.368 puts him top of the pile.

  36. 11:29:  
    Jennie Gow, BBC Radio 5 live pit-lane reporter in Bahrain
    Niki Lauda

    "I bumped into Niki Lauda in the pit lane and told him about the verdict in the Bernie Ecclestone High Court trial. Lauda went straight to his phone to try to ring Bernie, who was busy. Not surprisingly. The triple world champion, who drove for Ecclestone at Brabham in 1978 and '79, then went off to tell Red Bull team principal Christian Horner, who was with Sebastian Vettel and Red Bull motorsport adviser Helmut Marko. I wasn't privy to that chat, sadly."

  37. 11:27: 

    Nico Hulkenberg is back out and improves with 1:38.247. Sebastian Vettel follows suit soon after and goes half a second quicker than his previous best time with 1:40.340.

  38. 11:23: 
    Nico Rosberg

    F1 journalist Dan Knutson: "Nico Rosberg's Mercedes has been in the garage for about two hours now since it stopped out on the track. He had 45 laps out of 57 still to do in his race simulation today."

  39. 11:19: 
    Testing update

    Jean-Eric Vergne is back in the pits so as it is all quiet once again. A good time for a quick update on how the morning has gone in Bahrain.

    The issues that have been plaguing Renault-powered cars have been pretty much absent so far, with Red Bull managing 34 laps, more than they had managed in the pervious five days of testing, while Toro Rosso have completed the most laps off all so far with 53.

    Meanwhile, Mercedes have twice brought out the red flag with Nico Rosberg stopping on the circuit early on, before coming to a halt again midway through the morning.

    Ian, via text: Getting excited early this season I think the changes could see a couple of the mid-teams advance and shake up the big boys. But, and i don't mean to be picky, has anyone else noticed this multi million pound sport has a rusty old recovery truck to pick up Nico and his car :).

  41. 11:07: 
    Latest laps

    1. Jean-Eric Vergne (Toro Rosso) 53 laps

    2. Valtteri Bottas (Williams) 50

    3. Fernando Alonso (Ferrari) 49

    4. Esteban Gutierrez (Sauber) 48

    10. Max Chilton (Marussia) 14

    11. Kevin Magnussen (McLaren) 11

  42. 11:01: 

    Jean-Eric Vergne breaks the silence and heads back out on to the circuit as he looks to continue what has been a productive day for Toro Rosso so far - he has racked up the most mileage of all drivers having completed 53 laps.

  43. 10:58: 

    Kamu Kobayashi was briefly the only driver on track but he too takes the Caterham back into the pits and silence descends in Bahrain once again.

  44. 10:57: 

    BBC chief sports correspondent Dan Roan: "Constantin Medien tell me they intend to appeal after their claim against Bernie Ecclestone fails."

  45. 10:53: 
    Max Chilton

    I've not seen any signs of any sandwiches so far Mark, but Marussia driver Max Chilton tweeted his extremely healthy looking lunch a littler earlier.

    Get involved

    Mark Smith: Wonder what sort sandwiches each driver likes.

  47. 10:44: 

    Mercedes: The team are still investigating the issue that caused us to stop earlier. Hoping to be back out on track soon.

  48. 10:42: 

    The track is empty as Fernando Alonso is back in the pits, but it sounds like Toro Rosso could be about re-emerge, with Jean-Eric Vergne tweeting: "So far so good. We will soon be back on the track!"

    It is a much better day all-round for Renault-powered cars, with Toro Rosso having got 53 laps under their belt so far, and no sign of the troubles that hav plagued Red Bull as yet.


    Bernie Ecclestone has won his multimillion-pound High Court fight with a German media company.

    A judge has ruled in favour of the Formula 1 boss, who was being sued for £85m ($140m) in damages.

    The case was brought by German media group Constantin Medien, which claimed it lost out when the Formula 1 Group was sold in 2006. It accused Mr Ecclestone, 83, of entering into a "corrupt agreement" with a German banker to facilitate the sale to a buyer chosen by him.

  50. 10:37: 

    Fernando Alonso is still out on the circuit as Esteban Gutierrez heads in. Alonso is on a run of very slow laps, with his recent efforts all over two minutes.

    Get involved- 81111

    Owen, via text: The red flags must be really frustrating during testing, why don't they have an allotted period when it is treated as a race? Any cars that breakdown should be dealt with in the same way as a race which means that the teams can do a full race distance without an interruption. I'm following the testing whilst sitting in a kids play area near Manchester - half term and it's helping to keep me sane!

    Stay strong Owen, stay strong.

  52. 10:27: 

    Kamui Kobayashi grabs a personal best with 1:44.354 but it still almost two seconds off the pace of the rest of the field. He pits, with Esteban Gutierrez in the Sauber heading out to join Fernando Alonso on the circuit.

    "Proving even Mercedes love curling - it's lunchtime here in Bahrain."

    You can watch the curling online and on BBC Two, just remember to keep this window open too. It is all about multi-tasking!

  54. 10:12: 

    Valtteri Bottas clocks the fastest time of the day so far with 1:37.635 while Fernando Alonso is lapping in the 1:43s, suggesting the Ferrari could be embarking on a longer run.

  55. 10:04: 

    The circuit is open again and Kamui Kobayashi is straight out in the Caterham, swiftly followed by the Ferrari of Fernando Alonso.

  56. 10:03:

    "A few more details on the new contract Lotus have signed to continue with Renault engines in Formula 1.

    "Although the two parties said they had signed a deal "for 2014 and beyond" BBC Sport has learned the contract lasts until 2018, which underlines both parties' commitment to F1 despite Lotus's recent cash-flow problems."

    11. Kamui Kobayashi (Caterham) 1:45.059

  58. 09:56: 

    The Toro Rosso is on its way back to the garage so we should be back under way again shortly.

  59. 09:47: 

    The red flag is out for the third time and this time it is for Jean-Eric Vergne's Toro Rosso, which had been pounding the tarmac today.

  60. 09:45: 

    Romain Grosjean heads back out on to the circuit as he looks to add to his 13 laps so far today. Nico Rosberg, meanwhile, is still in the Mercedes garage.

    "Prior to his second stop on the circuit of the day, Nico Rosberg has been doing a race distance run," F1 Journalist Dan Knutson says. "The Mercedes crew held his car, which was running, in pit lane to simulate the heat build-up when it is on the grid before the start of a grand prix."

  61. 09:41: 

    BBC sports news correspondent Dan Roan: "This is a civil case, a lawsuit, so on paper there's only money at stake for Ecclestone. But in reality the ramifications go far beyond that. In April, the most powerful man in F1 must stand trial in Germany on bribery charges over the same scandal that landed him in the High Court. He has already had to stand down from the board of F1 as a result, although he remains in day to day charge.

    "A Constantin win today would effectively mean that the judge believed Ecclestone had paid a bribe. This would heap yet more pressure on the 83-year-old, and his employers CVC, and make it more likely the criminal trial in Germany could go against him. A guilty verdict in Munich would probably mean a prison sentence.

    "But if Ecclestone prevails today, his position is strengthened, and the German case seems less perilous."

  62. 09:39: 

    The verdict is due to be handed down in about one hour for an £86m High Court lawsuit against Formula 1 chief Bernie Ecclestone. The BBC's chief sports correspondent Dan Roan has more details...

  63. 09:33: 

    The track is open again but it seems a few of the drivers might be looking to follow Kevin Magnussen's lead and grab a sandwich or two. Valtteri Bottas, Jean-Eric Vergne and Esteban Gutierrez do decide to delay eating for a bit as they head out.

  64. 09:29: 

    McLaren: Extreme measures in place to stop sandwich theft.

  65. 09:22: 

    Nico Rosberg came to a stop in the first sector but he is back in the pits and we should be back under way in the not too distant future.

  66. 09:19: 

    We have our second red flag of the day and it appears to be for the Mercedes of Nico Rosberg once again...

  67. 09:18: 

    It has just passed 12pm in Bahrain and although there is no official break for lunch, the circuit tends to quieten down at this point as drivers take the chance to grab a bite to eat. Kevin Magnussen, fourth fastest today, is the first to tuck into the spread laid on at McLaren.

  68. 09:15:  
    Andrew Benson, Chief F1 writer

    "It's an encouraging start for Williams after losing day one of this test to fuel-system problems. Valtteri Bottas is currently third fastest, with a decent time of one minute 38.615 seconds. The Finn is cutting a more svelte figure this year. Already a fitness fanatic, Bottas has taken seriously the need to lose a couple of kilos because of the need to be as light as possible as a result of the difficulties teams are finding getting down to the minimum weight limit. When 3kg equates to 0.1secs of lap time, these things are important and the highly-rated Finn, who has lost in the region of 2-3kg, looks super-trim."

  69. 09:12: 

    Sebastian Vettel moves up the timesheets with his best lap of testing so far in Bahrain, clocking 1:40.540. Fernando Alonso still leads the way, ahead of day one pacesetter Nico Hulkenberg, while Williams are having a good session after a troubled first day, with Valtteri Bottas third fastest.

    Most impressive rookies- 81111

    Catherine, via text: Best F1 rookie of recent years - you've got to include Vettel. From Toro Rosso and winning his first race in 2008, to starting his four-year winning streak in 2010. In the time I've left school, gone to uni and got two degrees, he's cemented himself into the F1 history books. Pretty impressive for someone who is still only in his mid-20s and will no doubt only get better in the rest of his career.

  71. 09:05: 
    Red Bull

    A couple of cars back out on the circuit after a flurry of activity in the teams' garages. Not much to see with the screens up as soon as the cars are wheeled back but one of the more interesting sights is that of Sebastian Vettel's Red Bull, which is greeted by an army of blowers when it returns in an effort to keep it cool. Those overheating issues still a cause for concern.

  72. 09:02:  
    Andrew Benson, Chief F1 writer

    "I've been taking a closer look at the lap times from the first day's running. Nico Hulkenberg was fastest in the Force India, but that was on soft tyres and a short three-lap run, which suggests low-ish fuel. Fernando Alonso's Ferrari, meanwhile, set its fastest time on an eight-lap run on slower medium tyres, which means that while he did a 1:37.879, the car was capable of doing at least a 37.683, once the weight of fuel was taken into account. And of course there was quite probably more fuel in it than that. Lewis Hamilton set his best time in the Mercedes on an 18-lap run on hard tyres, which takes his fastest time of 1:37.908 down to at least a 1:37.432."

    Andrew Benson, Chief F1 writer

    "Ferrari continue to go about their business in a quiet and understated fashion. There was aerodynamic work on Wednesday, as well as tuning of the braking system but, in the middle of it all, there was Fernando Alonso popping up second fastest, and that was no one-off low-fuel run either. The Spaniard said nothing of consequence on the team press release, but Ferrari themselves were moved to describe it as a 'good day'. The double champion continues his work on Thursday."

  75. 08:50: 

    Ferrari: Smooth programme so far but the wind has increased a lot: not ideal conditions!

    Fernando Alonso still leads the way this morning with his time of 1:37.700 the only one below 1:38.

  76. 08:46: 

    Nico Rosberg passes through the pitlane in the Mercedes for a practice start. The track has quietened down as midday in Bahrain approaches, with Jean-Eric Vergne and Valtteri Bottas out there.

    It is another beautiful day in Bahrain with blue skies above the Sakhir circuit. It is also warm, warmer than it was at the same time yesterday, with air temperature 25 degrees Celsius and track temperature 29C. Caterham's Kamui Kobayashi becomes the 11th and final driver to record a timed lap as he clocks 1:48.079, the slowest so far.

    Sebastian Vettel

    Sebastian Vettel's Red Bull had been tucked up back in the garage for the best part of the last hour, but the German is back on the circuit and quickly improves his time for the day, 1:41.850 moving him up one place on the timesheets to eighth fastest.

  82. 08:15: 

    Kamui Kobayashi is back in the pits, with Caterham reporting they are having a couple of telemetry issues at the moment. They are expecting to send him back out again soon.

  83. 08:12: 

    All 11 drivers have been out at some stage now but we are still waiting on three of them to set timed laps - Esteban Gutierrez (Sauber), Kamu Kobayashi (Caterham) and Romain Grosjean (Lotus). Meanwhile Max Chilton has posted a time in the Marussia with 1:42.511, but has only managed two laps in the two hours we have had so far today.

    Pete Naylor: While everyone's focused on the troubles Red Bull are having, I'm more excited by just how quick Kevin Magnussen's looking!

    Gellert Szemeti: Magnussen is looking great so far, but the real test is the first race. He has a great car, he could be in the top six.

    "Nico Hulkenberg and Force India were the names on the top of the time sheets on day one in Bahrain, but not too much should be read into that. Quite apart from the usual provisos about this being only testing, unknown fuel loads, car specs, etc etc, Hulkenberg did his time on a three-lap run on soft tyres, which no-one else used. He found, as Sauber's Adrian Sutil pointed out, about 2.5secs by doing so. The Force India looks a tidy package, as ever, and it has the Mercedes engine, but barring a topsy-turvy, mixed conditions qualifying session, it is unlikely to be on pole in Melbourne."

  86. 08:03: 

    Nico Hulkenberg, fastest on the circuit yesterday, moves up to second on the timesheets with 1:38.394 in the Force India.

  87. 08:00: 

    Romain Grosjean does indeed head out in the Lotus, with its intriguingly designed nose, and completes an installation lap before returning to the garage.

  88. 07:55: 

    Lotus: A bit of a lie-in for the E22 this morning, but it must be about time to hit the track?

    McLaren are looking to bounce back from their worst F1 season in 33 years. Just how big a part could Kevin Magnussen play for them this season? The youngster says he is inspired by Lewis Hamilton's performance in his rookie season, when he narrowly missed out on the world championship, do you think Magnussen could be a realistic title contender this year? Staying on the subject, whose rookie season was the most impressive for you in the history of the sport?

    Kevin Magnussen, who was fastest on his McLaren debut on the third day of testing at Jerez, has the third best time so far today with 1:39.958. Magnussen was also fastest in the morning of the first day of this Bahrain test and is earning plenty of praise throughout the paddock for his performances so far.

  91. 07:48: 

    Red Bull: Morning from Bahrain. 35 laps done at testing so far. Only 348 laps to go! Playing lap catch up to Mercedes, Ferrari, McLaren.

  92. 07:47: 

    Mercedes: We've got another surprise for you today. Save the time.. 12.30 UK time. Lewis Hamilton fans you're going to like this…


  93. 07:46: 

    Good news for Lotus as Romain Grosjean is now getting into the E22 and looks set to join the rest of the field on the circuit shortly. Meanwhile, Fernando Alonso goes fastest of all with 1:37.700.

    "Lotus had a difficult first day of testing with their new car, but they feel they are on track given the limited running they have been able to do. Incidentally, it seems that they, like Red Bull, have also been delayed by engine partner Renault delivering parts later than expected to the track."

  95. 07:36: 

    The Red Bull mechanics are clearly still erring on the side of caution. Sebastian Vettel returns to the pits and as he does so there are one or two mechanics waiting with fire extinguishers tentatively aimed at the rear.

    Vettel called on a marshal to bring over an extinguisher after he came to a stop yesterday, and he explained: "There was an issue with the brakes that caused a lock of the back tyres. That created quite a lot of heat - and suddenly it was too hot under the cover. That was when I had to help the marshal with the extinguisher."

  96. 07:30: 

    Could the delivered items be doing the business? Sebastian Vettel becomes the fifth driver to record a timed lap this morning as he takes the Red Bull round in 1:43.357.

    Red Bull

    "Red Bull are certainly having a few problems, but they don't lack for resources when it comes to solving them. As happens with regularity at grands prix, the team had a massive box of freight delivered to them this morning. They were seen unpacking it just after the session had begun."

  98. 07:26: 

    Valtteri Bottas takes Williams to the top of the timesheets as he clocks 1:39.241 with his first timed effort. They struggled for time on the circuit yesterday, so are running with their day one programme at the moment. Meanwhile, Nico Rosberg has been back out on the circuit after his early morning stop, so all seems well again with the Mercedes.

    "There were mixed messages from Renault after Wednesday's first day of running in Bahrain. Trackside engineering chief Remi Taffin said the company had 'basically achieved' its aim of 'putting everything together so we could run as we wanted'. But while Caterham managed 68 laps, Toro Rosso and Lotus did only 13 between them. Lotus had an issue with the energy store - which was one of the many areas that had problems at the first test in Jerez - and Toro Rosso the electrics.

    "And after saying last week that they believed their hardware problems with fixed, leaving only software and control issues, Taffin admitted on Wednesday Renault 'need to keep working on our hardware, which we are doing night and day'. The best summary seems to be along the lines of another remark Taffin made: 'We had some problems, which are not as big as we had two weeks ago, but we have to fix them. That's where we are - on plan but still recovering.'"

  100. 07:22: 

    The lap counter keeps ticking over for Toro Rosso as Jean Eric-Vergne goes round the Sakhir circuit for the 17th time this morning. Caterham provided the one positive for Renault yesterday as they completed 68 laps, could it be Toro Rosso's turn to rack up the mileage in a Renault-powered car today?

  101. 07:16:  
    Jennie Gow, BBC Radio 5 live pit-lane reporter in Bahrain

    "It turns out it was nothing serious when Nico Rosberg's Mercedes stopped out on track earlier. A sensor led them to hit the kill switch on the car but they aren't too worried. They do have a lovely made to measure cover for their car though which loops down under the chassis and covers the floor from our prying eyes! Executive director (business) Toto Wolff and non-executive chairman Niki Lauda were both watching from the garage."

    Gomer Pyle: Nice to see red bull wobble, but I suspect by the start of the season Sebastian Vettel will win.

    TheCultOfPersonality: Genuinely don't think the Red Bull problems are an act/over exaggeration. They're four time world champions...

  103. 07:13: 

    Both McLaren's Kevin Magnussen and Marussia's Max Chilton have joined Jean-Eric Vergne in setting timed laps this morning and Magnussen, who has been impressive in testing so far, has just gone top of the timesheets with 1:39.958.

  104. 07:07: 

    While the vast majority of movers and shakers in the world of Formula 1 are in Bahrain and focused on testing, there is one very important person with something else on his mind today.

    Formula 1 boss Bernie Ecclestone is expected to learn of the result of the £86m High Court lawsuit against him sometime this morning.

    German media giant Constantin Medien are suing, claiming they lost out because Ecclestone deliberately undervalued F1 when it was sold in 2005/06 to the private equity company CVC Capital Partners, in order for him to retain control of the sport.

  105. 07:02:  
    Jennie Gow, BBC Radio 5 live pit-lane reporter in Bahrain

    "Happier faces at Toro Rosso who have done more laps today than all of yesterday and we're only one hour in. Jean-Eric Vergne has completed 10 laps so far."

  106. 07:00: 

    As our chief F1 writer Andrew Benson mentioned earlier, Red Bull's appearance on the circuit this morning had been put back one hour and right on cue, Sebastian Vettel heads out in the RB10 for an installation lap.

  107. 06:56: 

    Lotus, incidentally, are the only team along with Red Bull still to make an appearance this morning with just under one hour gone, as Valtteri Bottas takes the Williams out.

  108. 06:54:

    "A measure of the problems in which Renault finds itself was inadvertently provided by Lotus's Romain Grosjean. After doing just eight laps on the first day of public testing of the new E22, the Franco-Swiss admitted the team would not even try to find the best handling balance before the first race. 'I don't really care about set-up work,' Grosjean said. 'That's going to be when we are in free practice (in Melbourne). It's just about fixing all the issues and making sure the car is in one piece when we do long runs.'"

  109. 06:51: 

    Speaking of Renault, there was some news announced this morning with the engine manufacturer confirming the extension of their partnership with Lotus "for 2014 and beyond."

    Matthew Carter, Lotus F1 chief executive officer says: "Lotus F1 and Renault Sport F1 have enjoyed a successful partnership these past few years and we look forward to continue to build on our relationship and collaboration in 2014 and beyond."

  110. 06:48: 

    Renault F1: Now back to the track action - second day in Bahrain. Still a hefty job list but mood is confident.

  111. 06:47: 

    Mercedes say they are investigating what caused Nico Rosberg to come to a stop at turn eight this morning. The mechanics were being as secretive as ever as they desperately keep the car covered after it was returned to the garage.

  112. 06:40: 

    Jean-Eric Vergne is the first to post a timed lap as he clocks 1:42.676. Toro Rosso look like they could be set to try and make up for time lost yesterday. Max Chilton, who spent yesterday doing promotional shots around the paddock, takes out the Marussia.

  113. 06:35: 

    Oh dear. I hope Sebastian Vettel has got his phone packed with plenty of television programmes. It might be another long wait in the Red Bull garage. Meanwhile, the track is open again and out streams Kevin Magnussen in the McLaren, as well as Esteban Gutierrez, Fernando Alonso and the Renault-powered Toro Rosso.

  114. 06:33:  
    Andrew Benson, Chief F1 writer

    "More delays for Red Bull. Fitting new parts that arrived last night means Sebastian Vettel will miss the first hour of running on Thursday."

  115. 06:31:  
    Jennie Gow, BBC Radio 5 live pit-lane reporter in Bahrain

    "Nico Rosberg's car has been towed back to the pits, where it is greeted by a familiar scene. Just as with other cars in a similar predicament, it is lifted off the truck while cloaked with screens by mechanics desperately trying to keep its secrets away from prying eyes. Mercedes GP non-executive chairman Niki Lauda skulks in the garage."

  116. 06:29: 
    Sebastian Vettel

    Sebastian Vettel was still smiling yesterday despite spending much of it sitting around twiddling his thumbs. The world champion admitted that the issues that plagued them at Jerez had been fixed, but other problems had arisen yesterday.

    He said: "Very often, you fix one problem then another problem pops up so I think there is stuff to do on the Red Bull Racing side in terms of reliability, temperatures, in general around the car, and there's stuff on the Renault side.

    "Obviously we're not happy with where we are right now but we still have a long way ahead of us."

    Fester Addams: Red Bull are imitating brilliant boxers before a contest - exaggerating a slight injury to bluff the crowd and competition.

  118. 06:20:  
    Andrew Benson, Chief F1 writer

    "While Renault and Red Bull stagger from problem to problem, the Mercedes teams in general - and the factory outfit in particular - continue to look strong. Only Fernando Alonso's Ferrari stopped it being a Mercedes-powered one-two-three on Wednesday and Lewis Hamilton, third quickest despite some problems with his brake-by-wire system, admitted he had had another 'encouraging day'. He added: 'It's been really impressive just to see everything come together and to get the mileage, especially when everyone's showing how difficult it is with the new regulations. It's too early to say where we are, but the good thing is if you look at the timesheets it's always Mercedes at the top.'"

  119. 06:18: 

    It would appear to be the Mercedes of Nico Rosberg that came to a halt. A slight concern that they would seem to have had a problem so soon after Rosberg headed out. Mercedes had looked good on the first day in Bahrain, with Lewis Hamilton getting more than 70 laps under his belt, although the Briton did say he was troubled by some braking issues.

  120. 06:15:  
    Andrew Benson, Chief F1 writer

    "Twenty laps over four days in the first test, 14 over one on the first day of the second. That was progress of a kind for Red Bull on Wednesday, but Sebastian Vettel still admitted to German journalists that the team had 'a mountain to climb' ahead of the new season. It seems the problems that delayed their entry on to the track by five hours and brought their running to an end with nearly an hour and a half still remaining were car issues rather than engine ones, but the team insisted that 'while it might not appear so on the surface, there has been a big improvement since Jerez'. Thursday marks the halfway point of the entire F1 pre-season testing schedule. Can the world champions finally get their programme off the ground?"

  121. 06:13: 
    Driver line-up

    That red flag gives us a moment to have a quick look at the driver line-up for today:

    Red Bull - Sebastian Vettel

    McLaren - Kevin Magnussen

    Mercedes - Nico Rosberg

    Ferrari - Fernando Alonso

    Lotus - Romain Grosjean

    Force India - Nico Hulkenberg

    Sauber - Esteban Gutierrez

    Toro Rosso - Jean-Eric Vergne

    Williams - Valtteri Bottas

    Marussia - Max Chilton

    Caterham - Kamui Kobayashi

  122. 06:12: 

    No sooner has the track opened for day two of testing, we have our first red flag of the day. Nico Rosberg and Esteban Gutierrez were out on the circuit at the time.

  123. 06:08: 

    Welcome to day two of the second pre-season test in Bahrain. The first test at Jerez last month was pretty much a write off for Red Bull but Adrian Newey, the team's chief technical officer, did believe the world champions had got to the bottom of their problems.

    Then yesterday happened.

    Almost five hours of inactivity for Sebastian Vettel was followed by a handful of meaningful laps before the RB10 fizzed out on the circuit, a worrying smell of burning emanating from the car as it was towed back to the garage. All eyes will once again be on Vettel and Red Bull to see if they have finally got to the root of their problems today.

    You know that feeling when you just fit a new bulb and another one pops? Or you proudly install a new bath panel, only to discover you broke a pipe and now have a water leak? That must be how the Red Bull mechanics must be feeling about now as they hope a new dawn brings with it a new start...
