1445: So that concludes today's events from the Hungaroring. Saturday's session will be intriguing - can Ferrari spoil the Red Bull party? Join Sam Lyon tomorrow but for now, thanks for tuning in.

1441: Despite Red Bull's dominance throughout Friday's two sessions, Fernando Alonso has managed to keep up with the impressive pace of Vettel and Webber, giving the Spaniard an excellent opportunity to make an impression during Saturday's qualifying session. Ferrari team-mate Felipe Massa is fourth while Vitali Petrov has the opportunity to help secure his future with Renault following a confident display. The Russian is fifth, ahead of both McLarens and team-mate Robert Kubica.

BBC 5 analyst Anthony Davidson: "The body language of the McLaren cars is saying a lot. It's a bit twitchy and a bit nervous, both drivers are not able to let it flow."

From Adrian, London, text 81111: "Bernie Ecclescake?"

1432: The chequered flag flutters in the breeze as Michael Schumacher loses control on Turn 2. Once again the Red Bulls are the team to beat.

1429: Sutil returns to the track as Lewis Hamilton is struggling with pace, over four seconds down on Vettel's time on sector two. Neither McLaren looks at ease on this track, a big concern for the Woking-based team.

1425: With just under five minutes to go, almost all the cars are out on track. Only Adrian Sutil and Kovalainen are in the pits.

From Matt Cheshire, Adelaide, text +44 7786200666: "Felipe Massala?"
Remember that game?

1419: Pit-lane reporter Holly Samos has been down to the McLaren garage to ask why they are so far off the pace of the Red Bulls. "No issues, we're all fine" is the response. When it was pointed out that the Red Bulls seemed very fast, the response was: "They are."

1417: The early advantage of the soft tyres is wearing off as none of the drivers can build up sufficient momentum to give Vettel a decent run for his money. Both McLarens are out of the pits, along with Vettel and Robert Kubica.

1414: Alonso clocked 1:20.584 with his best lap time. Meanwhile, we're on board with Nico Rosberg and the German is really fighting with the car with 5 live experts Anthony Davidson and Karun Chandhok suggesting the Mercedes is carrying a large fuel load.

BBC 5 live pit-lane reporter Holly Samos: "The floor is going back on Adrian Sutil's car. It was an electrical powerbox problem, but he should be able to go out again."

1409: Alonso separates the two Red Bulls in first and third with an impressive lap as Webber returns to the pits. Meanwhile, issues with the hydraulics have forced Heikki Kovalainen back into the pits and it's highly unlikely the Finn will be back out in the remaining 21 minutes.

1406: Sensational from Vettel, who storms to the top of the standings with a lap of 1:20.87 and once again goes quickest through sector two, but traffic in the final sector sees the German lose almost half-a-second. But both Red Bulls are looking frighteningly fast.

1402: An honourable mention to Vitali Petrov, who fires his Renault up into fourth position with a lap of 1:21.195, almost a second in front of team-mate Robert Kubica. The Pole is hindered by a Virgin coming into the home straight and cannot find sufficient speed to propel him up the board. Russian Petrov's future at Renault has been questioned this week, so a strong showing in Hungary - in front a considerable gathering of his fans - will do his future prospects the world of good.

1356: Hamilton is on the super-soft tyres - the first driver to use them today - with about 35 minutes of the session to go. But the 2008 world champion cannot get within sniffing distance of Mark Webber's time, clocking 1:21.308.

BBC Sport's Sarah Holt in Budapest: "On the undercard to Lewis Hamilton's win here last season, Nico Hulkenberg claimed victory in the GP2 race. Now he's driving in F1 for Williams, Hulkenberg is hoping his experience round the Hungaroring can propel him to a solid top-10 finish on Sunday. But the German reckons Sauber's Kamui Kobayashi is the best rookie in 2010 because his season has not quite gone according to plan. 'We would have expected a bit more from our car in speed,' says Hulkenberg. 'I was hoping to have more than two points by race 12 but you have to be realistic. It's positive to see that we're able to climb out of the lower midfield and be able to battle for points.' As for his future, Hulkenberg adds: 'I have a two-year contract but there are always options. You'd have to ask Sir Frank.'"

1350: Alonso slips in a useful lap and moves into third place, leapfrogging team-mate Massa. A little less controversy than last Sunday.

1344: And Webber once again regains the top of the standings with a lap of 1:20.733.

1341: Nothing really changing at the top with the two Red Bulls in one and two, followed by the two Ferraris of Massa and Alonso. The two McLarens are in sixth (Button) and seventh (Hamilton) with Nico Hulkenberg in sixth.

1334: The man sitting to my left has just come up with Robert Kupizza, but I'm stumped. Come on, you lot will have loads. Let's have your suggestions via 606 or text on 81111 (UK) or +44 7786200666 (worldwide) with F1 before your message.

BBC Sport's Sarah Holt in Budapest: "Hello again. A pleasant lunch time in Hungary even though the breeze has picked up and clouds are ominously fringing the undulating circuit. Heads were no doubt being scratched at Force India. After putting the tyres on the wrong cars last week in Germany, Paul di Resta ran in first practice with a set of hard tyres which are allocated for sole use during Saturday's sessions and the race. For every one else, the tyres will in theory gve more grip as the dirty track 'rubbers in' - as if the Red Bulls' pace in first practice wasn't ominous enough for their rivals. A paddock murmur also revealed the friendly Toro Rosso boss Franz Tost is nicknamed French Toast. Any other edible F1 names out there?"

1329: The two Ferraris sit in third and fourth with Felipe Massa ahead of Fernando Alonso. Also running well in the second session is Williams' Nico Hulkenberg, who clocks 1:22.117 on his 12th lap.

1326: Vettel closes the gap on Webber to just 0.040secs before setting the fastest lap so far with 1:20.733.

From Steve, Edinburgh, text 81111: "Robert Kubica has been impressive and consistent all season so far and all without an F duct. Are Renault still on track to have one for Spa and do you think we could see a podium or two from the Pol?"

1321: However, Alonso's lead at the top is short-lived as both Red Bulls leapfrog the Spaniard with Mark Webber in front with a time of 1:21.046, 0.278secs ahead of team-mate Sebastian Vettel.

1314: Ferrari's Fernando Alonso sets an early marker with a lap of 1:21.826, the fastest time of the second session.

5 live analyst Anthony Davidson on Glock's slide: "It's a very tricky corner, if you've got a bit of instability on the rear it can really catch you out. But then against that he's got the headwind and that should be helping out."

1311: Timo Glock's Virgin looks like he has locked his rear wheels as he slides across the penultimate turn, but the German manages to stay cool and keep control of his car. "Traffic is a nightmare," laments Jenson Button over the team radio.

1309: Timo Glock runs too wide and onto the astroturf negotiating a corner, with bits of what looks like paintwork flecking off the chassis across the rough surface. 5 live pit-lane reporter Holly Samos says neither Ferraris are running the F-duct for this session.

From Simon, Manchester, text 81111: "Can everyone calm down about McLaren's pace please?! It's FP1, it's more than likely Lewis and Jenson were doing wildly different set-up runs to everyone else. Not unless Lewis had his hands behind his back would he be down in 15th in terms of real pace! Oh and the diffuser will only get better, don't forget Ferrari and even Williams have had it for four races and Red Bull all season, we can't expect McLaren to just 'switch it on' and go 0.5s quicker after one full race weekend."

BBC Sport's Sarah Holt in Budapest: "McLaren were confident they could close the gap to Red Bull and Ferrari on Hungary's high downforce track but first practice told a varied story. Button was fourth fastest - 1.6 seconds off Sebastian Vettel's top time - while Hamilton was three seconds off the pace in 18th. The team say they were running a different programme of evaluation than their normal Friday routine and that those P1 times are not necessarily reflective of both drivers' true form. Button came back to McLaren HQ after P1 and said he was happy with the car while Hamilton said he wasn't so happy with the balance, especially on his low-fuel run. Hamilton also had an issue with his front suspension (changing the torsion bar, for technical types) but it shouldn't cause any real problems."

1240: Jenson Button's McLaren sits in fourth behind Kubica with a best time of 1:22.444 from 17 laps this morning. Team-mate Lewis Hamilton managed 15 but could do no better than 1:24.075 and is way down in 18th in a Jaime Alguersuari (17th) and Jarno Trulli (19th)sandwich. So what lies in store for session two? Thoughts via 606 or text on 81111 (UK) or +44 7786200666 (worldwide) with F1 before your message.

1232: Hello again, while England's tail crumbles like a stock cube in the first Test against Pakistan at Trent Bridge, the world of Formula 1 is once again in awe of the pace of the two Red Bulls in the first practice session at the Hungarian Grand Prix. The RB6s of Sebastian Vettel and Mark Webber were rapid over the twisty turns of the Hungaroring, with Robert Kubica's Renault almost a second behind Australian Webber in third place.

1042: So that's it from me for the first practice session - we'll be back in a few hours for the second 90-minute instalment at 1300.

From Anon, text 81111: "McLaren's blown diffuser still not working properly. Lewis should abandon it if he wants to maintain his lead."

1035: Vettel cannot improve on his best time but the Red Bulls are once again the cars to beat - Robert Kubica's Renault is almost a second behind Mark Webber's RB6. Ominous - and that front wing is going to stir all sorts of conversations during the break.

1033: With 30 seconds to go Sebastian Vettel has enough time to squeeze in one final lap while Massa makes a complete faff of his final first-practice lap by going too wide on the first corner. The Ferrari pulls into the pit lane as Vettel bears down on him. A good show from Sauber's Pedro de la Rosa, who is sitting in sixth behind Rubens Barrichello and in front of fellow Spaniard Fernando Alonso with a time of 1:22.764secs.

From Jake, text 81111: "Normally I love to see teams exposing loopholes in the rules to come up with clever designs. However, to me it seems the loophole is the way the FIA tests the parts which seems wrong to me."

1028: Felipe Massa has a few issues around Turn 4, hitting the outside of the kerb before regaining control without too much concern. 5 live analyst Anthony Davidson says it's a difficult corner to negotiate but a joy to drive when you absolutely nail it.

1025: BBC weatherman Ian Fergusson says it is currently raining in Siofok, southwest of Budapest, so there is a distinct possibility of showers later on in the second practice session. The clouds are low but not grey enough to threaten a track drenching...

1022: The RB6 is clearly enjoying racing around the Hungaroring as Sebastian Vettel breaks the 1:21 mark with 1:20.976. Just under nine minutes to go until the end of the first practice session. Lewis Hamilton is back out on the track again, some three seconds off the pace, after completing eight laps.

From Tony, Glasgow, text 81111: "If the flexible wings are legal, there'll be a lot of 'not in the spirit of the rules' comments like there were with the diffusers. "

BBC Sport's Sarah Holt in Budapest: "Force India are the latest team to add the exhaust blown diffuser, which increases downforce, to the rear of the car. Adrian Sutil is running with it in first practice while Paul di Resta goes without in the other car so the team can compare data. Sutil says: 'We expect a few tenths out of it. We know it can make a very big difference if you use it properly but it's the early stages of development.' In Germany, the team mistakenly fitted a tyre belonging to Tonio Liuzzi's car to Sutil's and vice-versa which is not allowed under the rules. Sutil says: 'We had a little mess in this race. Sometimes I make mistakes and sometimes my team does.' It's only the second race this season, however, that both Force Indias have failed to finish in the points.'"

1015: On the final lap of his stint Renault's Vitaly Petrov loses his car going into the final corner, and then reverses on to the racing line in order to give himself room to get going again. Not the most impressive driving of the morning.

1013: The fastest lap time at the Hungaroring was set back in 2004 by Michael Schumacher in a time of 1 minute 19.071secs. The German is way off the pace at the moment with 1:22.792 but Jenson Button - who won his first ever grand Prix in Budapest in 2006 - is up to fourth with 1:22.444secs while team-mate Lewis Hamilton is off the pace after eight laps with 1:24.075secs.

BBC commentator Jonathan Legard: "Jaime Alguersuari made his Formula 1 debut here at the Hungaroring a year ago when he was thrown into the deep end as a replacement for Sebastien Bourdais at Toro Rosso. Because it's now a familiar track, it's one less problem for him to have to think about at the start of a race weekend. He says he can concentrate more on the balance of his car and his performance. I didn't know until this weekend that he was a keen golfer - he suddenly said Formula 1 can be like golf, one moment you think you've got it with what feels like the perfect shot and the next hole it all goes wrong and you feel like you're starting again. Toro Rosso have their first major aerodynamic update of the season here and both Alguersuari and team-mate Sebastien Buemi are aiming to be on the fringes of getting into the final session of qualifying."

Bridgestone's Andy Stobart: "Not a lot of activity takes place at the Hungaroring. Motorsport in the country is such that the track isn't used much, so it's pretty green and pretty dirty and dusty. We've brought super-soft tyres, which should give a good lap, and medium tyres, which have a bit less grip. They should be a good combination for the race. I know Felipe Massa likes it."

1003: Looks like Webber's flexible front wing is doing its business as the Australian usurps team-mate Vettel with a lap of 1:21.106 on his 18th lap.

1001: On board with Mark Webber and the flexible front wing of the RB6, which has been causing a bit of a stir, visibly rises in the closing stages of a lap but unfortunately the race director decides to look elsewhere just as the 5 live team are poised to analyse the innovation braking around Turn 1. However, replays show the Australian's front wing moving considerably into the rundown to Turn 4, while Lewis Hamilton's McLaren looks almost rigid in comparison going into the same stretch of track.

From Canis on 606: "I am interested to see if the tests on the front wings of the cars include the 'further tests' that are available, as it is obvious that Red Bull and Ferrari have constructed front wings that pass the standard tests - but can still flex at the end plates further than the 10mm in the rules. Very clever of them and all credit for doing so, just hope the other teams work out the trick and copy it soon or this season could end up being finished early...."

0950: The live video is up and running again on the website following a few technical problems earlier. Refresh your web browser to pick up the welcome update. Meanwhile Sebastian Vettel leapfrogs Red Bull team-mate Mark Webber by recording the fastest lap of the session with a time of one minute 21.275secs. Robert Kubica is not too far behind with 1:22.228 with Rubens Barrichello and Michael Schumacher fourth and fifth fastest.

Red Bull team principal Christian Horner: "At Hockenheim Ferrari were at least as quick as us, maybe even a sniff quicker. Hockenheim suited them a little bit better than us, but their pace has been evident for a while, and I'm sure they'll be quick around here - but I'm also sure the circuit will suit our car, and our drivers like driving here."

From 5 live analyst Anthony Davidson: "The fans do understand that this [team orders] happens in F1, and that it has done for years. [But] they're really upset about the way they were treated by Ferrari in laughing off the situation afterwards. The problem was the way that they did it. Certainly, that's what I was upset about anyway."

0942: The Red Bulls of Mark Webber and Sebastian Vettel are at the top of the timings at the moment, with the Australian topping the field with a fastest time of one minute 21.710. Both RB6s are smoothly into their rhythm, an ominous sign for the rest of the field? However, no show from the Ferraris as yet. Meanwhile, Hispania's Sakon Yamamoto is complaining about a misfiring engine over the team radio.

From Mark Wilson, text 81111: "The team orders thing is a lot of fuss about nothing. Team orders are part of F1. What annoyed me at the last race was the total over reaction of various commentators including on the usually so good BBC. Team orders are here to stay, get over it!"

BBC Sport's Sarah Holt in Budapest: "With or without team orders, Felipe Massa was always going to be the centre of attention on his return to Hungary, where last year he survived a life-threatening crash when he was hit on the helmet by a loose spring from Ruben Barrichello's car. Massa said he wouldn't even give the crash a second thought when he goes back on track. Barrichello - his pal and fellow Sao Paulo resident - says: 'I promise you he's really like that. I don't think he will fear anything.' In fact, Barrichello revealed Massa already showed a sense of humour about the episode in a recent poker game. 'Massa put the helmet from the accident on the table and it destroyed my night,' Barrichello said. 'It completely destroyed my night, I started losing money with the poker and he had fun with it. I think he's going to drive flat out.'"

0929: Contrary to previous suggestions, Mercedes are running the Hockenheim-spec new rear wing - on Nico Rosberg's car at least. They're running slowly, trying to gather early aerodynamic information. It's also worth remembering that this race will be a year and a week on from Felipe Massa's horrific accident during qualifying for last season's Hungarian Grand Prix . Although the headlines have focussed on last week's events in Hockenheim, the Brazilian is keen to thank all the marshals and medical staff who looked after him following the crash.

0921: More apologies but our live video on the website is not working, so we've taken it out for the moment. We'll put it straight back up again once it's fixed. But in the meantime you can watch the action and listen to David Croft and the 5 live team via the red button on your digital television.

0917: Red Bull team principal Christian Horner: "This morning we are a little bit limited because we only have one set of the hard tyres and you have to be a bit careful with as the circuit is bit dusty and we have to wait for some cars to clean it up. Then when a few cars have been out, we'll be looking into different ride heights, make sure the car's not bottoming, dial the drivers into the circuit, and then this afternoon we will be doing some set-up comparisons."

0915: Hispania driver Karun Chandhok on the Ferrari team orders controversy: "They've got a long way to catch up and realistically Fernando is their best chance of the championship."

0907:BBC weatherman Ian Fergusson is forecasting showers for Saturday in Budapest, which means there could be a bit of rain to contend with for qualifying. But for the moment it's glorious early-morning sunshine as all the drivers bar Lewis Hamilton and Heikki Kovalainen are on the track. Oh dear, there's smoke coming out of the back of Jarno Trulli's Lotus. Not good.

0900: So will Ferrari continue their excellent pace from Hockenheim? Or will McLaren's blown diffuser come good at the tight and twisty Hungaroring, where overtaking is not particularly easy? Let's have your thoughts via 606 or text us on 81111 (UK) or +44 7786200666 (worldwide) with F1 before your message.

BBC Sport's Sarah Holt in Budapest: "Hello again. I hardly had time to get my dark and white washes done after Germany before arriving in Hungary three short days later for the Hungarian Grand Prix. There are more pressing hangovers from Hockenheim and the paddock has been abuzz with the rights and wrongs of team orders. Fernando Alonso and Felipe Massa have had to face the music after switching positions in Germany, allowing Alonso to win. Full credit to Massa, who was plunged into the media conference and kept his chin up while facing the barrage of questions. Alonso spoke later at the Ferrari motorhome and batted away any searching questions while saying there is no number one driver at the team. Any frustrations can be worked out on the track during first practice and there were plenty of fans queuing for 'jegys' - the Hungarian for tickets - this morning."

0854: Early apologies - we are having technical problems with live video on the website but hope to have it up and running as soon as possible. However, you can watch the action through the red button on your digital television.

0850: No doubt you've probably had an opinion or two following last weekend's controversy at the German Grand Prix. Well, I know you've had an opinion or two to say - Andrew Benson's blog on the incident has drawn over 1600 comments so far. But for now it's time to look ahead to this weekend's action in Hungary and the 4.381km/2.722 mile track a short hop away from the capital Budapest.

0840: So it's official - Felipe Massa is not Ferrari's number two. Well, according to the Brazilian anyway. The 29-year-old is set for an emotional return to the Hungaroring, which is where we are going right now...
