11:45 Welcome back to AUTOSPORT Live as we continue to follow the opening day of practice for the Hungarian Grand Prix.

Technical debriefs have taken place during the break, and the teams have made set-up changes to the machinery in readiness for another 90 minutes of track action.

Heikki Kovalainen11:47 Earlier this morning, the drivers took to the track for the first time this weekend on a dusty and dirty surface for 90 minutes of free practice. One young man in particular could feel the eyes of the world upon him - Formula 1 debutant Jaime Alguersuari.

The 19-year-old Spaniard got the ball rolling with an impressive first run of laps as he learned the circuit, steadily improving his lap times all the while. But soon, the Toyotas were setting the pace, and then the flood gates opened.

Suddenly the track was very busy and it was Red Bull's Mark Webber who topped the time sheets with a best lap of 1m22.615s. That mark proved unbeatable for much of the session, as the teams got down to serious set-up and tyre testing work.

Webber's mark was still there with only a few minutes to go, but ultimately he dropped down to fourth as Lewis Hamilton went quickest, followed to the top by Nico Rosberg and finally Heikki Kovalainen in the dying moments of the session.

Kazuki Nakajima finished a positive session for Williams in fifth spot, with Jarno Trulli sixth and the Ferrari pairing of Kimi Raikkonen and Felipe Massa seventh and eighth.

Flags11:49 Motor racing enthusiasts love to debate and discuss the action on track, and the live forum at the bottom of the screen is your chance to let everyone know your thoughts on events as they unfold at the circuit.

• Will McLaren and Williams continue their strong form from the morning session?

• Can Jaime Alguersuari back up his very good early runs this afternoon?

• ...and what of Red Bull and Brawn? No doubt they have been running race-stint fuel levels this morning, but on the other hand Vettel was unhappy with his tyres in first practice and Jenson Button's problems of the last month with tyres are well documented. What do you think is the primary factor for their midfield times, fuel load or tyres?

11:51 Conditions haven't changed at all since the end of this morning's session. We still have clear blue skies and strong sunshine beating down on the track.

There is a slight breeze from the west, but the maximum temperature is high today at 32 degrees Celsius.

The heatwave across this part of the world is about to end, however. Later today we will look ahead in detail at the weather prospects for Saturday and Sunday on the Hungarian Grand Prix weather page.

Alguersuari11:53 Some brief points ahead of the second practice session:

• Debutant Jaime Alguersuari helped Toro Rosso complete 79 laps - the most of any outfit this morning - as team and driver got used to one another and a radically-revised STR4. The car now features the developments that propelled forward sister team Red Bull Racing at the British Grand Prix.

• At the other end of the laps completed count was Force India - the team that surely will be worried the most about the improvements at Toro Rosso.

• Lucas di Grassi set the fastest time in practice for this weekend’s GP2 Series round with a best time of 1m28.261s - four seconds off the slowest Formula 1 pace.

Di Grassi fastest in Hungary practice

• Since last year, a few cosmetic changes have occurred around the circuit. Additional conveyor belts have been added for safety reasons at Turns 5, 8 and 9, and a new debris fence has been added to the retaining wall exiting Turn 14.

11:55 Second practice gets underway at the Hungaroring in five minutes.

11:55 The track temperature is up to 45 Celsius in the afternoon sunshine. The ambient is 28 degrees.

11:59 Routine work is being completed on Sebastian Vettel's Red Bull Renault. The German is already bolted into the car and is ready to go out when the session begins.

11:59 Nick Heidfeld will be the first man out and is waiting for the light in his BMW.

0 min: The practice session is underway.

0 min: The Toyota pairing of Jarno Trulli and Timo Glock follow Heidfeld onto the circuit.

0 min: Heidfeld leads the cars out as the light at the end of the pitlane flicks to green.

0 min: Nico Rosberg and Jaime Alguersuari join them on track.

1 min: Sebastien Buemi also comes out in the second of the Toro Rosso entries.

The standard form in this session is that the drivers have no need for an installation lap, and they will be setting times quite quickly.

2 min: Nick Heidfeld is already on to a timed lap as the session gets up and running immediately.

2 min: Jarno Trulli and Timo Glock cross the line to begin their first timed laps in the session.

3 min: Kazuki Nakajima and Giancarlo Fisichella come out to join the racetrack. Meantime several drivers are already on their first run.

3 min: Heidfeld sets the first time of the afternoon at 1m25.193s.

3 min: Trulli and Glock slot into second and third places behind the German.

4 min: Jaime Alguersuari's first effort this afternoon is a 1m28.349 as he sensibly builds himself up slowly.

4 min: Nelson Piquet is the next man to improve the early benchmark. The Brazilian has a full package of updates on his Renault today but did suffer a gearbox gremlin this morning.

5 min: Nico Rosberg goes second to Piquet with a lap of 1m24.403s.

6 min: Kazuki Nakajima briefly makes it a Williams two-three behind Nick Heidfeld.

6 min: The majority of cars are on track for the traditional busy start to second practice.

The harder of the two tyres remains the choice of the field at this stage.

6 min: Nick Heidfeld is back on top with an improved time of 1m23.953s.

6 min: Giancarlo Fisichella pops up from the midfield to third spot with a lap of 1m24.125s.

7 min: Red Bull drivers Sebastian Vettel and Mark Webber are on their first timed laps, as we see Nakajima take over the top spot with a 1m23.910s lap.

7 min: Lewis Hamilton has slotted in third quickest with his early efforts in this session.

8 min: Kimi Raikkonen has been wide in Turn 3 but the Finn kept going over the grass and is back up to speed.

9 min: Nelson Piquet is now at the top, with Sebastian Vettel up to second place after his second flying lap. Kazuki Nakajima is third with Nick Heidfeld fourth. However, the order won't stay like this for long ...

10 min: Meanwhile, Felipe Massa has been off the road more substantially as he lost the Ferrari at Turn 9. The Brazilian has managed to bounce the car over the gravel trap and escape around the edge of the gravel.

11 min: Fernando Alonso joins his team-mate in the top five as the Spaniard clocks the fourth quickest time.

11 min: Rubens Barrichello rolls out of the Brawn garage for the first time this afternoon. Tream-mate Button is in ninth place after five laps. He improves with a 1m24.204s to eighth on the following tour.

12 min: Lewis Hamilton is the next man to have a minor off as the drivers struggle for grip on the harder tyres. The world champion had a trip over the asphalt run-off at Turn 13.

12 min: Adrian Sutil is the only driver yet to come out onto the circuit. Prior to the start of the session, his Force India was up on stands in the garage, with serious work being carried out.

13 min: Nelson Piquet heads the list after 13 minutes of the session, with a quickest time of 1m23.414s. Vettel is second, with Nakajima third, Alonso fourth, Heidfeld fifth and Fisichella sixth in these early stages.

15 min: Jenson Button reports over the radio as his circulates that he is struggling with front end grip in the final two corners of the lap. Deja vu?

15 min: Heikki Kovalainen is on track with the harder tyres on his McLaren. He's the fastest man through the first sector and goes on to top the order with a 1m23.396s.

16 min: Nico Rosberg is the first driver we have seen to try out the softer option tyre so far today. The German vaults to the top of the pile with a lap of 1m23.116s.

19 min: Rosberg carries on for a second timed lap on the super-soft tyre, but predictably cannot manage the time he set to put him at the top. Helpful information for the rest of the teams as they continue with their tyre evaluation work.

20 min: Interestingly, Kazuki Nakajima is staying on the harder tyre for his run in the sister Williams. Direct tyre comparison work here for Williams.

21 min: Giancarlo Fisichella also has a set of the super-softs bolted on his Force India, and he improves to fourth spot, behind Rosberg, Kovalainen and Piquet with a time of 1m23.419s.

22 min: With the gear ratios changed in his Force India, Adrian Sutil has now come out onto the track for the first time this afternoon.

22 min: Nick Heidfeld is one of the few drivers on track at the moment and is currently eighth fastest in the BMW.

23 min: Fisichella continues to move up the classification and is now second on those super-soft tyres with a lap of 1m23.334s.

23 min: Sebastian Vettel is another to try out the softer tyres and he goes quickest of all with 1m23.013s.

24 min: Adrian Sutil slots into 15th position with his first flying lap - 1m24.412s.

24 min: Felipe Massa is currently propping up the order in 20th but is back on track for a run in the Ferrari.

25 min: Heikki Kovalainen now has the softer tyres on his McLaren.

25 min: Mark Webber now moves to the head of the field with 1m22.918s. Vettel makes it a Red Bull one-two with Fisichella third and Rosberg fourth after 25 minutes.

26 min: Kovalainen is the next man to top the times as he again puts the McLaren to the fore with a 1m22.126s on super soft rubber.

26 min: Felipe Massa springs up to seventh quickest as he finds some pace on the softer tyres.

27 min: Adrian Sutil has moved up from 15th to 12th in the Force India. His Force India team-mate Giancarlo Fisichella also improves and is in fifth spot. Giancarlo pits at the end of the next lap, bringing his first run to an end.

28 min: At Toro Rosso, Jaime Alguersuari is giving detailed feedback on the car's stability to his race engineer. The striking thing you first notice about him is how calm and relaxed he is, considering the circumstances.

29 min: Kovalainen continues his run. After a slow tour in the 1m29s, the Finn virtually matches his best time with a 1m22.132.

29 min: Jenson Button puts Brawn up near the front for the first time today, as he completes his latest lap in 1m22.811s. He is now second to Kovalainen, with Red Bull duo Webber and Vettel, third and fourth.

30 min: Kimi Raikkonen is also testing the softer tyres. He is up to ninth quickest.

32 min: Lewis Hamilton improves to tenth quickest with his latest lap, behind Massa seventh, Raikkonen eighth and Piquet ninth.

32 min: Rubens Barrichello is on a set of the harder prime tyres for this current run of laps. He is down in 15th position, almost two seconds off the pace.

33 min: Kimi Raikkonen improves to fourth as he puts a long run on the softer tyres.

35 min: Jarno Trulli posts his quickest time of the session so far, but remains down in 17th position.

Meantime, Button's front-end issues are all-too-evident on the timing monitor. Personal best first and second sectors are followed up once again by a slight loss of time in the final few corners of the lap, as he battles to get some front-end bite in those final, long corners.

35 min: Robert Kubica deploys the super soft rubber on his BMW to move up from 20th to ninth. The softer tyre is clearly providing good grip this afternoon.

39 min: Sebastien Buemi was attempting to find the limit as he continued on a run. He found that alright, as the rear end locks up slightly under braking for the chicane at Turns 6 and 7. The Swiss drivers backs off the throttle and takes to the grasscrete on the inside of Turn 7, before rejoining the prepared surface without damage.

Buemi pitted at the end of that lap.

40 min: As the teams continue their preparations, their work is not helped by some problems with the timing system at the circuit, which is not properly displaying all the sector times.

41 min: Adrian Sutil posts his quickest time of the session so far, and moves up into 11th spot with a lap of 1m23.441s

Up front, Heikki Kovalainen is at the head of the list with Button second, Weber third and Raikkonen fourth.

43 min: While Heikki Kovalainen continues to top the order, team-mate Hamilton is on a lengthy run with the harder tyre.

43 min: Timo Glock exchanges a set of the harder tyres for the softer option, and as a direct result a couple of minutes later he swaps 20th position for second, with a time of 1m22.778s.

45 min: Many of the drivers are struggling with the final sector of the lap. This is not limited to Jenson Button by any means.

for the last 15 minutes we have seen several drivers post improving sector times in the first and second sectors of the lap, only to lose momentum in the final few corners.

46 min: Having sampled the softer tyres, Felipe Massa is back out on the harder tyres and is once again struggling for grip on that option. He continues after a moment at Turn 7.

46 min: Kazuki Nakajima has slipped down the order to 12th position as other drivers have improved. He is back out there with a set of the super-soft tyres fitted to the car ... but yet to improve as we see Rubens Barrichello spinning to a standstill.

47 min: Meanwhile, Jarno Trulli is touring around the early part of the lap and has eventually pulled to a stop in the Toyota.

48 min: Barrichello locked up entering Turn 12 and spun onto the asphalt run-off area but was able to rejoin, but there is more drama.

51 min: Just like the buses, we get two incidents at once. Trulli ground to a halt just after Turn 7 and pulled his Toyota onto the grass and gravel, with some fire licking out from the rear of the car.

51 min: The stricken Toyota has now been craned away from danger and Jarno has climbed out of the car.

53 min: Robert Kubica moves up to fifth quickest with a lap of 1m22.870s in the BMW.

53 min: Up front, Heikki Kovalainen remains at the front of the field with a 1m22.126s lap. Mark Webber has just moved up from fourth to second in the Red Bull Renault, and is now 0.243s down on the quickest time.

Timo Glock is third and Jenson Button is fourth, with Robert Kubica fifth and Kimi Raikkonen sixth.

55 min: The Williams duo are evenly matched. Nico Rosberg and Kazuki Nakajima are ninth and tenth at the moment, and both have set an identical 1m23.116s.

55 min: Felipe Massa continues to struggle on the harder tyres and has been off the road again. He pits the Ferrari.

58 min: Nick Heidfeld pits after a run with the softer tyres on his BMW. He remains down in 19th.

58 min: Jaime Alguersuari has quietly been going about his business during the afternoon. The Spaniard has completed 28 laps so far in this session, and he is trying out the softer tyre on this latest run. He is 18th at the moment with a best time of 1m23.942s, 1.816s shy of the leading pace.

59 min: Fernando Alonso moves up to tenth quickest in the Renault as he tests the softer tyres.

59 min: Timo Glock improves in the Toyota, but remains in third position. A 1m22.751s on his latest lap of the track.

60 min: Lewis Hamilton is up to seventh quickest with his latest lap of 1m23.012s.

62 min: Alonso continues his run on the softer tyres and is now up to fourth with his latest effort of 1m22.793s.

62 min: Jarno Trulli has made it back to the paddock, following an incident where he stopped out on track at Turn 12. He is quickly approached by reporters and he tells them that an electrical problem ground the TF109 to a halt.

64 min: Rubens Barrichello has leapt up to third place in the classification with the aid of a set of super-soft tyres. The Brazilian posts 1m22.641s which is just over half-a-second away from Kovalainen's leading pace.

64 min: Lewis Hamilton continues to test the softer tyres and has improved his time for seventh quickest after a number of laps on those tyres.

68 min: Hamilton was on for another improvement on his softer tyres but he made a mistake and took to the run off at Turn 7.

69 min: Improvements in lap time are few and far between in recent minutes as the teams are solidly into their programmes of work for the race, rather than looking for outright speed.

As we move into the final 20 minutes of the session, a few more drivers will try out the softer tyre option, and may even take out some fuel.

Williams look like the first team to up the ante as we see both Nakajima and Rosberg on the super-soft tyres.

70 min: Nico Rosberg uses his softer tyres to good effect and moves up to second quickest with a lap of 1m22.154s - just 0.028s behind Kovalainen.

71 min: Nakajima similarly moves up the order, to fourth place with 1m22.628s. He is on for a further improvement on the next lap ... and he does, lowering his own time to 1m22.426s. He remains in fourth.

72 min: Jarno Trulli's broken Toyota has been transported back to the garage. The team will now be able to check the data and electrical systems on the car to find out what stopped the car some time ago.

74 min: Heikki Kovalainen is back on track for another run on the softer tyres. Team-mate Hamilton has recently pitted after a lengthy run on the same option.

75 min: Jenson Button is not the happiest man at the Hungaroring, as he continues to grapple with corner entry issues in the Brawn.

His race engineer Andrew Shovelin reminds him that he can change the sngle of the adjustable front wing should he want to. Jenson responds by stating that adding any more front flap is making the rear twitchy.

Jenson just can;t find the sweet spot at the moment.

75 min: Jarno Trulli's Toyota has been repaired, and the Italian is now back out on the circuit for another run of laps, with 14 minutes remaining.

76 min: Kimi Raikkonen is on track again to test the softer tyres. He moves up one place from 11th to tenth with his latest lap.

77 min: Felipe Massa has switched to the softer option but is still not happy with the Ferrari. He tells engineer Rob Smedley on the radio that he thinks the car has a problem with the front wing.

79 min: As we move into the final stages of the second practice, Heikki Kovalainen is - as he has been for a long time - at the top with 1m22.126s. Nico Rosberg is second, with Mark Webber third and Kazuki Nakajima making it two Williams in the top four. Rubens Barrichello is the best of the Brawns in fifth, with the Toyotas of Trulli and Glock sixth and seventh.

That is a good recovery from Trulli, moving from 20th to sixth with 1m22.663s.

82 min: Jenson Button is back out on the circuit. He is tenth in the standings as we move into the final eight minutes of the session.

84 min: The cars are streaming out for a final attempt at a time.

86 min: Lewis Hamilton fails to improve after his first lap on the softer tyres. Replays show he ran wide at turn two, spoiling his effort early in the lap.

87 min: Sebastien Buemi has completed 42 laps this afternoon in the Toro Rosso. We see him beginning another timed lap, but coming into Turn 2 he throws the front end of the car into the left-hander and the rear says 'sorry, I can't match that' and steps out. He corrects the steering and simultaneously locks up the unloaded left-front tyre.

He soon runs out of road and drifts wide onto the asphalt run-off area on the outside of the corner, before continuing on. He has stayed out on track, but has slipped to 16th as Adrian Sutil improves to 13th in the Force India.

87 min: Hamilton tries again, setting the fastest sector before finding traffic in the form of Nakajima's Williams. Lewis missed his braking for Turn 12 and again failed to set a good time.

88 min: The only driver not on track in the final minutes is Mark Webber. The Australian has suffered a mechanical problem during the second half of the session and won't be able to set any quick laps at the end.

Meantime the other 19 drivers are out there and pushing hard to improve their time.

89 min: Lewis Hamilton is again the fastest man through the first sector as he tries again for a fast lap on the softer tyres.

90 min: Through the final sector cleanly this time, Hamilton finally takes the top time in 1m22.079s.

90 min: Nico Rosberg sets his quickest first and second sector times on his latest lap but it's the same old story - lost time in the final sector and he does not improve on second place.

90 min: The session has ended. Cars that have already started a lap may complete it.

13:31 Kazuki Nakajima tried a set of the softer option tyres on his final run but fails to improve. Same deal for Rubens Barrichello. He ends the day seventh.

13:32 There were few improvements in that late scramble as the drivers seemed to struggle for pace throughout the full lap.

13:32 Late incidents for Jarno Trulli and Nelson Piquet also brought out yellow flags in the dying minutes.

13:35 McLaren Mercedes fans can walk away from practice with a smile as Lewis Hamilton and Heikki Kovalainen end the day in the top two places after another busy practice session. Hamilton's late lap was 1m22.079s with his team-mate just 0.047s adrift.

Nico Rosberg was third for Williams. He was also less than one-tenth of a second behind the leading pace, with Mark Webber ending the day fourth despite losing a lot of track time in the second half of the session.

Kazuki Nakajima was fifth in the second Williams and championship challenger Sebastian Vettel was sixth fastest.

13:38 The practice report is now available to wrap up a busy Friday at the Hungaroring:

Hamilton keeps McLaren on top

13:42 So the afternoon session finished in much the same vein as the morning: McLaren and Williams at the sharp end with Mark Webber in the mix.

Brawn fans will scratching their heads tonight as Jenson Button struggled to find front-end grip on a hot day when we all thought his tyre woes would disappear. More worrying for the Briton is that the temperature is expected to cool significantly for Saturday and Sunday.

It is nail-biting time for the Brawn fans and, with McLaren looking likely to upset the apple-cart, the rich pickings in terms of points might not be on for this weekend - again.

This situation sets us up perfectly for the second day of track action. Can Brawn recover and assert themselves or are they set to be swamped by the competition? Qualifying will go some way to answering that conundrum, but first there is the Saturday morning practice. Our coverage here on AUTOSPORT Live will begin at 08:45 GMT. We hope you can join us for that.
