    In total for testing McLaren have managed less than 200 laps. Every other team has managed well over 400, with Mercedes leading the way with over 800. Worrying times for McLaren?

  2. Day three testing times in full

    1 Pastor Maldonado (Ven) Lotus-Mercedes 1:24.348

    2 Max Verstappen (Ned) Toro Rosso-Renault 1:24.739

    3 Lewis Hamilton (GB) Mercedes 1:26.142

    4 Marcus Ericsson (Swe) Sauber-Ferrari 1:26.340

  3. Post update

    Mercedes

    Mercedes: Job done! 101 the total for Lewis Hamilton today - he's powered through these past couple of sessions!

  4. Chequered flag

    Out comes the chequered flag to bring day three to a close. Five drivers got over 100 laps under their belt, a figure Jenson Button can only look on enviously at after a frustrating day for McLaren.

    Pastor Maldonado finishes fastest for the day.

  5. Post update

    Mercedes: That's his century! 100 laps hit for Lewis Hamilton Howzaaaat! ;)

  6. Post update

    Jenson Button completes a lap, heads in, heads back out but soon heads back in again.

  7. Post update

    That's better, a 1:27.556 is almost two seconds quicker than Jenson Button's best effort, so Valtteri Bottas is up into ninth.

  8. Post update

    Ah, a late timed lap for Valterri Bottas but it is not enough to lift him off the bottom of the timesheet as he clocks 1:38.067.

  9. Post update

    Williams

    Williams: Final 10 minutes and Valtteri Bottas heads out with a clear visor as the light fades.

  10. Post update

    Sauber

    Sauber: One more run on the soft tyres.

  11. Post update

    Jenson Button heads out, he'd certainly welcome a few trouble-free laps, and he is quickly followed by Marcus Ericsson, Valtteri Bottas and then Pascal Wehrlein.

  12. Post update

    The green flag is waved and 10 minutes remain for teams to rattle up a few late laps.

  13. Post update

    Force India: Red flag halts proceedings. It may be a bit of a scramble for the pit lane once the session goes green again! Every lap counts.

  14. Post update

    It was the Toro Rosso that brought out the red flag and the recovery truck trundles over to lift Max Verstappen's car. Should be enough time to squeeze in a few more laps before day three of testing comes to an end.

  15. Post update

    Max Verstappen stopped just before Turn 1, while Jenson Button also came to a halt at the pit exit.

  16. Red flag

    McLaren head back out, but there is a red flag...

  17. Post update

    A bit more activity on the circuit as we enter the final 30 minutes with Sebastian Vettel increasing his lap total for the day in the Ferrari. Pascal Wehrlein, in the Force India, and Toro Rosso's Max Verstappen are also out there.

  18. Post update

    Force India: Pascal's tally is up to 77 laps, a very good haul for the youngster who has been through a plan of setup work and longer runs. The crew has completed some routine checks after the latest long run, so we're ready to put in some extra laps before the end!

  19. Post update

    Daniil Kvyat pops out in the Red Bull but is straight back in and once again the circuit is empty. Sensing there is little more to see today, spectators are starting to make their way home.

  20. Post update

    Pastor Maldonado cuts a lonely figure as he weaves his way around the circuit in the Lotus - the only car on the circuit.

  21. Post update

    McLaren

    Just over 45 minutes remaining of testing for today, will we see another appearance by the McLaren? Yes, is the answer, as Jenson Button ventures out but how many more laps can he add to the 18 he has completed today?

  22. Completed laps on day three

    1. Max Verstappen 125

    2. Daniil Kvyat 102

    3. Sebastian Vettel 101

    4. Pastor Maldonado 94

    5. Lewis Hamilton 86

    6. Pascal Wehrlein 76

    7. Felipe Massa 55

    8. Marcus Ericsson 46

    9. Valtteri Bottas 36

    10. Jenson Button 18

  23. Post update

    Nothing much going on on the circuit at the moment, with Max Verstappen and Valtteri Bottas performing pit-stop practices. Sebastian Vettel continues to increase his mileage on the circuit as he surpasses 100 laps for the day in the Ferrari.

  24. Get involved #bbcf1

    Tony Dickinson: Maybe this is a secret plan by McLaren to lull everyone into a false sense of security.

  25. Post update

    Marcus Ericsson, on the soft tyres, is up to fourth with 1:26.340, and the times from third fastest to seventh fastest are separated by nine tenths of a second.

    Ericsson, Max Verstappen, and Pascal Wehrlein are the drivers on the track at the moment.

  26. Post update

    F1 journalist Dan Knutson in Barcelona: "Williams did the same thing last year - doing pit stop after pit stop with the driver coming in after each lap and therefore never setting a lap time. Valtteri Bottas has now done 34 laps doing just that. It's expected that he will do some proper timed runs before the session ends."

  27. Post update

    Brief. Jenson Button is once again back in the pits after lap 18.

  28. Post update

    A limited-power McLaren is guided back on to the circuit by Jenson Button.

    Meanwhile, Daniil Kvyat has surpassed 100 laps for the day as he heads off on number 103. Only Max Verstappen, on 115, has managed more today.

  29. Post update

    Sauber

    Sauber: Pit-stop practice. Marcus Ericsson is now in the garage and gives feedback.

  30. Post update

    Andrew Benson

    Chief F1 writer

    "More on McLaren's problems. It turns out our earlier suspicions were right - McLaren's delays have been caused by the same part that stopped Jenson Button on Thursday, a seal on the motor generator unit that recovers energy from the rear axle (the MGU-K). A new design was fitted to the car for today's running and Honda hoped that would fix the problem. But it has not.

    "A spokeswoman said: 'After the morning session, the car fed back MGU-K issues similar to what we experienced on Thursday, so we brought it back to the garage. After a thorough check, we have decided to resume testing with limited power to the MGU-K. A new re-engineered seal is scheduled to arrive and will be applied later this evening.'"

  31. Post update

    It looks like it is a short stay back in the garage for Jenson Button, with the McLaren seemingly set to re-enter the fray. Meanwhile, Lewis Hamilton is back on the circuit, currently lapping in the 1:26s.

    Mark Snow: Hope McLaren have not scooped the 'F12015 sunk without trace award' again before the season's even got under way.

  33. Post update

    Valtteri Bottas is up to 30 laps without setting a time as Jenson Button heads back in at the end of lap 15.

  34. Post update

    Jenson Button completes his 14th lap of the day and stays out on the circuit. All being well, he will have 90 minutes out there to rack up the mileage.

  35. Post update

    ...and out goes Jenson Button, his first trip on to the circuit since this morning.

    Daniil Kvyat on his race simulation, pits for softs with 12 laps to go. Meanwhile, it seems like there may indeed be some activity in the McLaren garage...

    Chief F1 writer

    "McLaren say they hope to have Jenson Button out again 'very soon'. The team said that 'there were a number of things we had to check and some issues we had to address, which took some time'. They promise more details shortly."

  38. Post update

    McLaren

    No sign of the McLaren on the circuit yet, so here's a picture of a beaming Fernando Alonso stood behind the iconic McLaren MP4/4 from the 1988 season.

  39. Post update

    Lewis Hamilton completes an 11-lap stint on medium tyres, with the majority of those laps either 1:27s or 1:28s.

    Sebastian Vettel also completes a flurry of laps, heading in after his 16th in succession with those averaging in the 1:29s. He is closing in on a century of laps for the day and it is looking like being another pleasing outing on the circuit for Ferrari, despite his spin right at the start of the day.

  40. Post update

    Valtteri Bottas has yet to clock a timed lap, despite managing 22 laps. He has spent the afternoon doing some pit-stop practice.

  41. Testing day three update (as of 15:15 GMT)

    1. Pastor Maldonado (Lotus) 1:24.348 (63 laps)

    2. Max Verstappen (Toro Rosso) 1:24.739 (97 laps)

    3. Lewis Hamilton (Mercedes) 1:26.142 (72 laps)

    4. Sebastian Vettel (Ferrari) 1:26.407 (92 laps)

    5. Daniil Kvyat (Red Bull) 1:26.589 (81 laps)

    6. Felipe Massa (Williams) 1:26.912 (55 laps)

    7. Pascal Wehrlein (Force India) 1:27.333 (57 laps)

    8. Marcus Ericsson (Sauber) 1:28.858 (32 laps)

    9. Jenson Button (McLaren) 1:29.151 (12 laps)

    10. Valtteri Bottas (Williams) No time (22 laps)

  42. Post update

    Jenson Button will no doubt be itching to get back out on the circuit. He has now dropped to the bottom of the timesheet as Marcus Ericsson clocks 1:28.858 to move up to eighth. He heads back in, leaving Lewis Hamilton, Sebastian Vettel and Daniil Kvyat on track.

    Williams: More pitstops...This time the boys prepare for Valtteri Bottas to hit his marks.

  47. Post update

    F1 journalist Dan Knutson in Barcelona: "After a stint in the garage, Daniil Kvyat has resumed his race simulation, which had 32 laps to run. He has the medium compound Pirelli slicks on his Red Bull."

  48. Post update

    Lotus

    Jenson Button's lack of activity means he has completed just 12 laps on the third day of testing so far.

  49. Post update

    Andrew Benson

    Chief F1 writer

    "There has still been no sign of the McLaren-Honda this afternoon, and that is not good news for the team. Jenson Button has done only 12 laps so far and although the team said earlier that the stoppage Button suffered this morning was 'planned', one has to assume something else is wrong, because McLaren need nothing more than mileage at the moment. We're trying to find out what's going on."

  50. Post update

    Max Verstappen

    Lewis Hamilton pits after some mid-distance runs on the medium tyre and, at the moment, there is just Max Verstappen out on track. The rookie driver's best of the day - a 1:24.739 - keeps him in second.

  51. Post update

    Marcus Ericsson, on the medium tyre, clocks his best of the day, a 1:29.171 but it is just shy of Jenson Button's fastest and he remains bottom of the timesheet.

  52. Post update

    Red Bull

    F1 journalist Dan Knutson in Barcelona: "With 32 laps to go in his race simulation, Daniil Kvyat pitted and the mechanics pushed the car into the garage.

    "Prior to that the mechanics had been doing a race simulation of their own and sitting on chairs in the garage. But unlike a race weekend there was no TV coverage to watch."

    After a breather in the Lotus garage, Pastor Maldonado heads back out and he is quick, fastest of all through the first sector and...it's the fastest lap of the day - 1:24.348 on super softs.

    Frank Lopez: That size zero is yielding zero test results. Have McLaren shot themselves in the foot overcomplicating the car?

  56. Post update

    Lewis Hamilton and Sebastian Vettel are racking up the laps, the former lapping in the 1:28s with Vettel averaging around two seconds slower. Meanwhile, Daniil Kvyat ends his long run by returning to the Red Bull garage.

  57. Post update

    Pastor Maldonado improves again, joining pacesetter Max Verstappen in dipping below 1:25s as he clocks 1:24.917.

    Valtteri Bottas, meanwhile, has six laps to his name but is yet to set a time and interestingly, no sign of Jenson Button in the McLaren on the circuit this afternoon...

    Sebastian Vettel is out, but only briefly as he heads back into the pits after completing a couple of laps.

  67. Post update

    You may have been wondering where Lewis Hamilton is this afternoon. He is still in the Mercedes garage, posing for a selfie.

    He tweeted: "Hope you're having a great day! Still feeling under the weather but I'm pushing for you guys."

    The sun is breaking through the clouds, prompting one or two teams to start getting things ready for a venture on to the circuit, Pascal Wehrlein one of those as his Force India rolls out of the garage.

    The laps are ticking down on Daniil Kvyat's race simulation, too, with 'L61' on the Red Bull board. He has been lapping in the 1:30 and 1:31s.

    Force India: Still quiet in the garage as we wait for the track conditions to improve...

    F1 journalist Dan Knutson in Barcelona: "Red Bull is doing a very thorough race simulation. A crew member placed bottles of water at each of the seven seats on the pit wall where Christian Horner, Adrian Newey and the engineers sit (although they are not all out there now.)

    "Daniil Kvyat did one lap and then came into the pits, stopped 50 yards away from the Red Bull garage, and shut the engine off. The mechanics then pushed the car to the garage, just as it would be pushed from the back of the grid to its starting slot on the grid.

    "After a waiting period similar to what it would be on the grid before the start of the race, Kvyat then headed out with intermediate rain tyres fitted to the car, did one lap and pitted for a set of the soft compound Pirelli tyres. He is now off and running and doing the race sim."

  71. Post update

    This morning's pitstop practice is put to good use as Daniil Kvyat pits for softs and heads back out to begin his race simulation.

    Marcus Ericsson, meanwhile, is doing his best to make up for lost time with eight laps to his name so far, the best a 1:42.179.

    Everyone is briefly back in the pits, before Daniil Kvyat decides to head on to the empty circuit. He completed 34 laps this morning, spending most of his morning making practice pitstops.

  77. Post update

    Red Bull

    F1 journalist Dan Knutson in Barcelona: "Red Bull has a pit board with L65 on it ready to go. A race distance here is 66 laps, so it looks like Daniil Kvyat will be doing a race simulation soon."

  78. Post update

    Pascal Wehrlein takes the Force India out on to the circuit for the first time in the afternoon session, joining Lewis Hamilton and Max Verstappen, who is on the medium tyre.

    It appears some of the teams are waiting for the circuit to dry up a bit before heading out, with some areas still a little damp.

    After spinning off the cold track early on, it has been so far so good for Sebastian Vettel and Ferrari.

    The new car has been impressive in winter testing, surely we are likely to see Ferrari team principal Maurizio Arrivabene running barefooted at some point in this season?

    "I am not so crazy as to change the objectives now," Arrivabene said of the team's low-key objectives.

    "McLaren have revealed why Jenson Button stopped out on track early in the morning's session. A spokesman said that it was all part of the team's plan to check that the newly redesigned part of the hybrid system fitted for Saturday to replace the one that failed on Thursday was working as hoped. A spokesman said: 'We made a planned stop of the car to confirm the MGU-K re-engineered sealing part installed this morning.' Button has since returned to the track, but the drizzle of late morning limited his running before lunch."

  92. Not everyone takes a break...

    Red Bull

    F1 journalist Dan Knutson in Barcelona: "Red Bull has a lounge area set up next to the engineers' office on the top of the transporters. But even if it were not a bit too cool for the engineers to be lounging around outside, they have far too much work to do to take a break."

    Good news Sauber fans, looks like Marcus Ericsson has been pulled from his driver room and his about to get involved...

    What are your expectations for Max Verstappen in 2015? Is it too much to young or could he produce one of the most impressive performances by a rookie driver?

    Let us know via #bbcf1 or text to 81111 (UK only)

    An improvement from the rookie Max Verstappen as he first goes round in 1:24.739, almost two seconds faster than Lewis Hamilton, currently in second.

    Back to on the circuit matters, and Jenson Button is back out, three laps to the good on his return. Hopefully those earlier troubles are behind McLaren.

    Mercedes

    The top of my twitter feed has taken a bizarre turn with Mercedes tweeting a 'video' of Nico Rosberg doing the 'Nico Dance'.

    Not sure what more you can say about that...

  122. Post update

    Daniil Kvyat is back on the circuit and clocks 1:26.589 with his latest effort to move up to fifth fastest. Sebastian Vettel is also out there, with Pastor Maldonado soon joining them. No-one has joined pacesetter Max Verstappen in strapping on soft tyres.

    The earlier reported power issues for Jenson Button's McLaren has hampered his mileage this morning, he is the only driver to have been out on circuit to have a single figure lap count, having managed nine.

    He pops on to the circuit for an installation lap, but is back in and doesn't look to be out again any time soon.

    Lewis Hamilton is up to 30 laps for the day with his best time 1:26.142. He is on the medium tyre and has been lapping in the 1:36s, but shaves nine seconds off his latest run.

    He is the only driver on the circuit as Pascal Wehrlein, who had climbed up to fourth with 1:27.699, pits.

    "Was Friday the day Formula 1 finally glimpsed the potential of the 2015 Mercedes? It had been a low-key pre-season until then, but when Lewis Hamilton unleashed a lap only 0.3secs off the pace on tyres that were at least a second a lap slower than those used by everyone ahead of him, it did not take much imagination to work out what that probably meant. And race simulation runs done simultaneously by Hamilton and Red Bull's Daniel Ricciardo only strengthened that impression. Hamilton's average lap time was a whopping 0.816secs quicker than Ricciardo's. They were on different tyre strategies, but that is quite some margin."

  138. Post update

    I wonder if Lewis Hamilton has fully shaken off the effects of the illness that kept him out of the car on Thursday? He was well enough to get some time on the circuit yesterday, although conceded he still didn't feel 100%. He remains the pacesetter almost two hours into today's testing.

  139. Post update

    Still waiting for Daniil Kvyat to set a lap time this morning. He has been round the circuit 12 times for Red Bull so far, but has made a practice pitstop at the end of each lap.

    Max Verstappen and Sebastian Vettel improve on their benchmark times with laps of 1:27.417 and 1:27.864 respectively.

    "No-one is surprised that the Mercedes is showing so much pace. Domination of the level showed by the team last year does not evaporate overnight, and their rivals clearly have a lot of work to do, even if Nico Rosberg tried to play things down on Friday when he said: 'The others have really stepped up their game, the lap times are surprising to us and it seems Ferrari have made the biggest step right now.' He added that Ferrari were 'for sure' a threat, and that Mercedes' 'eyes are definitely wide open at the moment'."

    The circuit is green again after Jenson Button's McLaren was quickly recovered.

  146. A worry for McLaren?

    Andrew Benson

    Chief F1 writer

    "That is not what McLaren wanted - the car stopped by the side of the track less than 90 minutes into the day's running. The team will hope this is not a major issue, and that Jenson Button can be returned to running relatively quickly.

    "Another major delay would be a significant setback, and the prospect of it being as failure of the newly redesigned part on the MGU-K that was introduced for today does not bear thinking about."

'I am happy with the progress we are making.'

    "Jenson Button is back in the McLaren on Saturday, for what he hopes will be his first proper day's testing of the winter - and the team's for that matter. Fernando Alonso managed 59 laps on Friday, and at a decent-ish lick, but the Honda engine was then carrying a temporary fix to the problem with the hybrid system that had stopped Button on Thursday. That part has now been replaced with a new design, which Honda hopes will fix it for good. But racing director Eric Boullier made it clear how much McLaren had missed out with all the engine problems over the first half of testing, saying they had done '50%' of what they had hoped to do by this stage."

    "Fernando Alonso described what was effectively McLaren's first proper day of testing with the Honda engine as a 'beautiful day', as well he might when the 59 laps he achieved almost matched the total the team managed over the entire four days of the first test in Jerez earlier this month.

    "And considering the car was running with a botched fix on the Honda engine after a hybrid system failure on Thursday, the times weren't bad, either. 'Today finally showed to the team, to all of us, that we are in the right direction,' Alonso said. 'The potential of the car is there, with limitations or not the car feels good, feels quick.'

    "Jenson Button is back in the car today, and with what Honda hope will be a definitive fix for the hybrid problem they suffered on Thursday."

    Despite McLaren's struggles on Thursday, they had a much better day yesterday as Fernando Alonso set the sixth-fastest time and completed more than 50 laps after McLaren had cobbled together a fix for the engine problem that hampered Jenson Button.

    Good timing Nick, JB has just rolled out onto the circuit in the McLaren. Button will be hoping for plenty of running this morning having had to call a halt to proceedings after just 21 laps on Thursday.

    "It was Red Bull's Daniel Ricciardo who grabbed the headlines on Friday, edging out Kimi Raikkonen's Ferrari and Felipe Massa's Williams for fastest time. And perhaps more importantly for Red Bull it was their first day without any major reliability problems. Ricciardo said this was 'better' and that it was 'encouraging to see us in the front group of cars'.

    "The Renault engine, too, is an improvement: 'It definitely has some more ponies; we knew it would. it was a question of how much we could close the gap. we're not as fast in the speed traps but we have more to come.'"

    "If Sebastian Vettel has indeed lost control of the Ferrari and dropped it on his first lap out of the pits, he can console himself with the thought that he is not the first great champion to suffer such an embarrassment.

    "Those with long memories may recall that Alain Prost spun off on the warm-up lap for the 1991 San Marino Grand Prix. Vettel might not want to recall what happened later that season, though. Prost was sacked for making critical comments about the car."

    "Half-distance in the team's preparations for Formula 1 has passed, and there are only six days left before the cars finish pre-season testing and are packed up and then sent to Australia for the first race of the season.

    "So far, testing has been intriguing. Ferrari appear to have made a genuine step forward, Williams and Red Bull will be in the mix, and McLaren-Honda look as if they might just finally be extricating themselves from the mire of unreliability that afflicted their first five days of 2015. But Mercedes, clearly and obviously, remain the team to beat.

    "Will those impressions be changed over the forthcoming six days, starting this morning at the demanding Circuit De Barcelona-Catalunya?"

    Twenty one days and 21 hours; 31,500 minutes; 1,890,000 seconds. Whichever way you look at it, the first race of the 2015 Formula 1 season is fast approaching.

    Just over three weeks until lights out at the Australian GP, and we have just passed the halfway mark in pre-season testing.

    Is the reigning champion looking in good shape? Who could be his biggest challengers? All that and more could become clearer this weekend...
