04:30 Hello everyone and welcome to AUTOSPORT Live for what should be an amazing 17th round of the 2010 FIA Formula 1 world championship - the inaugural Korean Grand Prix from Yeongam.

Sebastian Vettel starts from pole position for today's 55-lap race and his Red Bull team-mate Mark Webber starts alongside him, but late last night the rain arrived to change the grip level of the circuit once again, and today the drivers face a completely unknown racetrack.

The Koreans have done a sterling job in getting the circuit ready for this weekend's event and an estimated crowd of 100,000 is expected at the 5.615 km circuit today.

The race begins at 06:00 GMT, but before then we will review yesterday's qualifying session, bring you up to date with the latest weather conditions and take a look at some of the main talking points going into the race.

04:35 It's all change on the weather front and last night at 10pm the first spots of rain began to fall at the Korean International Circuit. Overnight, the intensity of the rainfall increased and a total of around 15mm of rain has fallen in the last 12 hours. Since dawn, light rain has continued in showery form and we are set for a damp start to the race.

The circuit condition will now of course change dramatically compared with what we've seen over the past few days. The track surface was difficult enough to drive even in dry conditions, but with rain continuing to bring the oils in the final layer of asphalt to the surface, a treacherous mixture of dust, mud, oily patches and water could turn this afternoon's race into a speed skating competition.

High humidity and a low ambient temperature reaching just 20 degrees Celsius will help to keep the circuit in a damp or wet condition for much of the afternoon, guaranteeing fans an action-packed grand prix.

04:40 Five drivers remain in the hunt for the big prize in the drivers championship with Australian Mark Webber still leading the title race by 14 points with just three rounds remaining.

Fernando Alonso and Sebastian Vettel are both on top form and will be looking to cut that lead down before the Brazilian Grand Prix in two weeks time. Lewis Hamilton and Jenson Button have slipped back in the points standings over recent events and the British pair need a strong result here to avoid being cast out of the reckoning.

Reliability is critical at this stage of the season, and none of the top five contenders can afford a DNF.

Red Bull Racing holds a 45 point advantage over McLaren in the constructor's championship and the Milton Keynes-based outfit could even secure the title today if its rivals suffer a total disaster. Ferrari isn't out of the battle just yet, but if the Scuderia fails to get both drivers on the podium today then there is no chance the title will be returning to Maranello.
World Championship standings, round 16:

04:45 Sebastian Vettel and Mark Webber blasted their way to the front of the grid for Red Bull Racing as qualifying produced another one-two lockout for the Milton Keynes-based team.

Tonio Liuzzi once again found himself on the wrong side of the Q1 divide, as he failed to make it through to the next phase after another disappointing performance in the Force India. The Italian joined the six drivers from the three new teams on the sidelines and put his disappointment down to the fact that he was unable to run a set of soft option tyres in morning practice.

On went the rest of the field into a fiercely competitive Q2 session. Nico Hulkenberg tried as hard as he could in a desperate last-gasp bid to make it through to the top 10 shootout, but the German failed by just over one-tenth of a second and was joined by Kobayashi, Heidfeld, Sutil, Petrov, Alguersuari and his Toro Rosso team-mate Buemi on the elimination list.

Petrov went into the session with the knowledge that he would be taking a five place grid penalty whatever happened, following a start-line incident with Hulkenberg at the Japanese Grand Prix two weeks ago. The Russian overcooked things on his last attempt, spun out of contention and he will start from 20th on the grid this afternoon.

The quickest 10 drivers went into the shootout and Alonso immediately threw down the gauntlet to Red Bull with the quickest time after the first of two runs on soft tyres. The Spaniard even improved on his time slightly on the final run, but it was first Vettel with a sublime 1m35.585s and later Webber who came through to take first and second on the grid.

Alonso was demoted to row two and he will start alongside his old sparring partner Lewis Hamilton, with Rosberg fifth, Massa sixth and Jenson Button with a lot of work to do from seventh after he struggled getting temperature into his tyres.

04:50 As has been the case over the last few grand grix weekends, the FIA stewards had several incidents to investigate at the end of Saturday's activity. 1980 Formula 1 world champion Alan Jones joined them in administering the following actions:

• Not only did Adrian Sutil fail to make it through to the final phase of qualifying, but the German was also fined €1,800 after falling foul of the 100 km/h pitlane speed limit during Q1.

• Michael Schumacher was reprimanded by the stewards after an on-track altercation with the Rubens Barrichello during the second qualifying period. Barrichello was impeded between Turns 9 and 14 and, while the Mercedes team successfully argued that the Brazilian was not a 'hot lap' at the time, the FIA reiterated that all drivers should be aware of faster cars closing down on them and subsequently should give up track position.

• Nico Rosberg inadvertently baulked Fernando Alonso in the final minutes of Saturday morning's practice session. The stewards investigated the incident and decided that no penalty should be imposed.

• Robert Kubica was also the subject of a stewards investigation following a report that he had held up Adrian Sutil in the late stages of Q2. Having looked at the incident, the panel decided that no further action was required.

05:00 The traditional driver's parade ended a short time ago as the fans began to fill the main grandstand opposite the pits. Today, the stars of the show were herded onto a truck for the tour around the circuit, rather than the row of cars often provided at flyaway rounds.

Before that, it was the turn of the sole support event - for Hyundai touring cars - to entertain the soggy crowd. Things started badly, however, in very tricky conditions when a spinning car hit the wall and was collected by several rivals in the walled section of track heading onto the long straight.

With limited access and a serious lack of cranes, the marshals were unable to clear the sizable wreck before the 10-lap race ticked away entirely behind the safety car.

05:05 Here's how the grid will line up this afternoon:

Pos  Driver         Team
 1.  Vettel         Red Bull-Renault
 2.  Webber         Red Bull-Renault
 3.  Alonso         Ferrari

05:10 As Vettel, Webber, Alonso and Hamilton take up the front four positions on the grid this afternoon, there are quite a few factors to worry about - with the added pressure of the world title on the line.

Firstly, there's the very tight Turn 1 lying in wait with what looks to be one of the biggest bottlenecks off the startline of any circuit on the calendar. Even if they survive the first bend with some minor wheel banging, the 1.2km straight that follows means the dogfight for positions will continue during at least the opening 30 seconds of the race.

The extremely dirty side of the grid was a concern for Webber and Hamilton, but the overnight rain means things are now slippery all over the circuit.

Even if it does dry up, tyre choice is looking particularly difficult - with the extremely 'green' track conditions looking set to produce another Canada-style tyre shredder.

A wet start may just hold off the expected need for two stops, but look out for some serious graining and degradation on any slicks - particularly the first set used on a drying track.

Much to Vettel's concern, this race has all the hallmarks of being anything but processional.

Nico Rosberg is a strong fifth on the grid, with his Mercedes working well down the straights, and lines up ahead of Massa and Button, who needs a special performance to stay in title contention - which conditions today could help him produce.

Robert Kubica has also been quick down the straights in his Renault, but failed to find the time when it mattered and has a lot of work to do to progress from eighth. Schumacher, Barrichello, Hulkenberg and Kobayashi make up the chasing pack and could be well-placed to profit from any carnage between the title contenders.

05:15 Our look through the field continues with Nick Heidfeld who starts in 13th position for this afternoon's race. The German made his racing return at the Singapore Grand Prix four weeks ago and yesterday qualified less than one-tenth of a second behind Japanese entertainer Kamui Kobayashi.

Toro Rosso drivers Jaime Alguersuari and Sebastien Buemi start from 15th and 16th on the grid today. Both have already proved that they can hold their own in damp and slippery conditions, and, providing they can stay out of trouble on the first lap, a solid race towards the points is possible.

Jarno Trulli took the new team honours for Lotus in qualifying and the Italian starts from row nine, with the intention of moving forward as others falter in the slippery conditions. Today's race represents possibly the best chance for any of the new teams to sneak through to a vital points finish.

Vitaly Petrov is 20th on the grid following a five-place penalty for an over-aggressive start at Suzuka a fortnight ago. The Russian has a quick car underneath him and will be looking to go on the attack early, but first he will have to dispatch Trulli and quite possibly Timo Glock - who is known for making extremely clever tyre choices in changeable conditions. Expect the Virgin driver to try something different compared with those around him.

Sakon Yamamoto and Bruno Senna once again occupy the back row of the grid for Hispania Racing. Usually, it is expected that they will stay at the rear the field, but given today's track conditions, they could at least offer the Lotus and Virgin drivers a challenge.

05:20 Track conditions remain wet at Yeongam as we move to within 40 minutes of the formation lap. After a brief respite, the rain is beginning to fall once again.

The latest radar update shows that this shower will continue while the drivers complete their reconnaissance laps to the grid. This now guarantees a wet first stint to this afternoon's 55-lap race.

05:29 With a few minutes to go before the pitlane opens, Mark Webber has taken a walk out to the pitlane to examine how slippy the surface is underneath his feet.

In just a few minutes time the championship leader will roll out of the garage and ascertain the grip level for real.

05:30 The pitlane is now open for drivers to make their way around to the grid. The track will be open for 15 minutes and drivers will make one or more reconnaissance laps to the grid during this time.

They will want to check important basic functions such as the team radio, throttle, brakes, gearbox and engine settings. They may also play around with the front wing level from inside the cockpit.

Any driver not on the grid with 15 minutes to go will be required to start this afternoon's race from the pitlane.

05:30 Vitaly Petrov is the first man out of the pits with full wets on his Renault.

05:31 There is a huge plume of spray as the Renault is followed down the long straight by Alonso in his Ferrari.

05:31 There is a lot of water standing in the grassy areas to the side of the circuit.

05:33 Timo Glock has already found conditions tricky, looping his Virgin around on a lap to the grid.

05:34 Kubica heads out to test conditions on full wet rubber.

05:34 Sebastian Vettel has completed one reconnaissance lap on intermediate tyres and is now being wheeled back into the Red Bull garage by the mechanics.

05:34 Massa has been for a spin with intermediate tyres on his Ferrari.

05:35 Michael Schumacher has also been off the road. The German immediately ran wide at Turn 1 after exiting the pits.

05:35 Trulli pops in to the Lotus garage for a set of intermediate tyres.

05:36 Alonso is pushed back into the Ferrari garage after a lap on full wets. His team were busy changing a water pump in the last hour.

05:36 Mark Webber is also pushed back into the Red Bull garage, as his team-mate Vettel leaves with full wet tyres bolted onto the RB6.

05:37 Webber completed his reconnaissance lap on intermediate tyres and he may also go for a change to full wets.

05:37 There are no significant patches of standing water on the track, meaning intermediates should be the preferred tyre.

05:38 Bruno Senna is the latest man to explore the bounds of the circuit after outbraking himself at Turn 3.

05:39 Schumacher made it back to the pits and he is going out now with a set of full wet tyres bolted onto the Mercedes.

05:40 Massa pits once again for another chance to test the conditions.

05:40 Alonso is making his latest tour to the grid on intermediates.

05:42 Vettel is now on the grid after completing several reconnaissance laps using both types of wet tyre.

05:43 Alguersuari says he has "never driven with so little grip"

05:44 Nico Rosberg has finally arrived on the grid and chose full wet tyres for his reconnaissance lap.

05:45 The pitlane is now closed. Any car not on the grid by now will be required to start the race from the pitlane.

05:46 The rain continues to fall with moderate intensity.

05:46 The spectators rise in unison to respect the Korean national anthem, as it rings out over the Yeongam public address system.

"It is not an easy choice of whether you go for intermediates or full wets. It will be interesting to see what everybody does."
Nico Rosberg speaking to BBC TV

"The first thing is to try to finish the race. No one is going to win the title here, but someone could lose it."
Fernando Alonso, Ferrari, speaking to Spanish broadcaster La Sexta

05:50 There is a tense atmosphere on the grid as the teams ponder a very tricky tyre choice for the start.

05:51 The latest weather radar image shows that the rain could stop shortly after the race begins. Generally, the weather is expected to improve towards the late stages of the race.

05:52 The race engineers will be keen to use intermediate rubber if at all possible, with those tyres being the most flexible if things dry up.

05:52 Red Bull are understandably keen for a safety car start, which would force all drivers to use full wet tyres.

05:53 Rain is still falling as the drivers make their final preparations to climb aboard the cars.

05:54 AUTOSPORT's Jonathan Noble tells us that you can see the oily chemicals coming to the top of the asphalt on the grid.

05:55 There are five minutes to go until the formation lap begins at the Korean International Circuit.

05:56 The start of the Korean Grand Prix has been delayed by 10 minutes.

05:57 All 24 drivers did make it round to the grid so a full field will eventually take the start.

05:57 The track temperature is just 18 Celsius as rain continues to fall on the grid.

05:58 The safety car remains in position at the front of the grid awaiting further instruction from race director Charlie Whiting.

05:58 The rainfall has been particularly intense in recent minutes, moving the track conditions towards the full wet tyre.

06:00 Race control announces that the race will start behind the safety car.

06:01 That means all drivers will be forced to begin the race on the full wet tyre.

06:03 The rainfall radar shows in recent minutes that a line of showers may continue to affect the running of the race for at least the next 30 minutes.

06:04 Sebastian Vettel is advised on the Red Bull team radio that the rain intensity should not get any worse than it is currently.

06:04 The race will begin immediately as the cars pull off the grid at 10 past the hour.

06:05 Red Bull will be relieved by the call for a safety car start, but McLaren has been very strong in wet conditions this year.

06:05 The main grandstand is packed as the crowd patiently waits for the cars to roll away behind the safety car.

06:07 The hooter sounds to signal three minutes to the start.

06:08 The rain continues to hammer down at Yeongam, as the drivers sit in the cockpits of their cars waiting for the start of this race.

06:09 The engines fire on the grid with one minute to go before the safety car leads the field of 24 away.

Lap 1: The race is underway behind the safety car.

Lap 1: The safety car leads the field through Turn 2 and onto the long 1.2 km back straight.

Lap 1: The track is very wet now as the field snakes around the first lap.

Lap 1: There is an enormous amount of spray coming up from the cars as they attempt to stay behind the safety car on full wet tyres.

Lap 1: Button tells his team that it is "like a lake on the straight"

Lap 2: Vettel leads the pack into lap two on what could be a lengthy safety car period.

Lap 2: The safety car crosses the line and leads the field into the second lap of the Korean Grand Prix with heavy standing water evident everywhere.

Lap 2: Massa is told on the radio that there could be another 20 minutes of rain. Rob Smedley asks him to keep his tyre pressures up.

Lap 2: Bruno Senna has been into the pits from 24th and last position. He rejoins after a total of 25.3 seconds in the pitlane.

Lap 2: The cars are largely set-up for dry conditions, with only minor changes available to the teams such as front wing angle and brake cooling.

Lap 3: Alonso tells his team that it is the worst conditions he has ever driven in.

Lap 3: The race has been suspended. The cars will return to the red flag line on the start/finish straight to await a restart.

06:18 The drivers are slowly but carefully coming through the final sector towards the start/finish area.

06:18 Button says he can't even see his front tyres due to the spray on the straights.

06:19 The race clock has been suspended with 1h53m08s remaining.

06:20 Three laps have been completed as the pack re-forms on the grid.

06:21 The race will resume behind the safety car when conditions allow.

06:21 The cars have lined up in grid order and the mechanics now rush onto the circuit to carry out the usual routine checks and await further information.

06:22 The teams will have a ten-minute warning of the restart from race control.

06:23 The race needs to reach a distance of 42 laps for full points to be awarded.

06:23 The official Formula 1 weather radar shows that this rain will continue lightly for some time, but that conditions should improve in around half-an-hour.

06:25 Mark Webber has taken his helmet off so that he can get some fresh air, as he remains in the cockpit discussing the situation with the engineers.

06:25 Darkness will set in here after a couple more hours as it is already 15:25 local time.

06:29 The official sunset time is 17:50 in Korea, but the light will fade considerably before we reach then.

06:29 The Mercedes mechanics are making some adjustments to the area behind the brake reservoirs on Rosberg's car.

06:30 Hamilton has stepped out of his McLaren and is heading to the garage to dry off.

06:30 Safety car driver Bernd Maylander remains at the controls of the Mercedes as he keeps in constant contact with race control.

06:32 The rain is now falling lightly at Yeongam, as everybody waits to see when the 10 minute signal will be given.

06:34 Maylander has taken his helmet off and climbs out of the safety car to get some fresh air.

"Visibility is the issue. On the run to Turn 3 there is quite a lot of water to be honest. The best thing is to wait a while and then see how we go."
Mark Webber, speaking to BBC TV

06:37 Parc ferme conditions have now ended, so the teams can make set-up tweaks during this red flag period.

06:39 Bruno Senna is one of the many drivers who have climbed out of their cars as he awaits further instruction. He is currently adjusting his helmet and HANS device.

06:42 The official Formula 1 weather radar predicts that this rain will stop in just under 20 minutes.

06:43 Jaime Alguersuari sitting in the cockpit of his Toro Rosso, helmet off and contemplating what may - or may not - be over the next couple of hours.

06:43 All the surface oils in this very fresh asphalt mean it doesn't drain as well as a worn surface.

06:44 A team of marshals is taking the opportunity to sweep away any excess mud and dirt away from the edges of the circuit.

06:45 Adrian Sutil is standing on the grid and sharing a joke with his mechanics as he munches on an energy bar.

06:46 Tonio Liuzzi is advised on the Force India team radio that the light will become unacceptable by 17:45 local time.

06:47 But as we mentioned earlier, the natural light will start to fade sometime before then.

06:47 The leader has completed two laps, so half points could theoretically be awarded in grid order if the race does not restart.

06:48 A more likely scenario now is a restart after the track dries a little with the race curtailed by fading light.

06:48 Sebastian Vettel is standing on the grid with a team jacket on as he talks with the Red Bull engineers.

06:50 Mark Webber and Fernando Alonso are discussing the current conditions on the grid as the rain continues to fall lightly.

06:52 The duo are now joined by safety car driver Bernd Maylander to discuss the conditions. Red Bull team boss Christian Horner joins the group.

06:52 Webber is expressing his concerns about the lack of visibility and the possibility of a large pile-up if someone spins in the opening corners

06:54 Jaime Alguersuari is wearing a Toro Rosso team fleece as he walks down the pitlane with his race engineer.

06:55 The race will resume at 16:05

06:56 Teams are told that the cars must remain on full wet tyres for multiple laps behind the safety car.

06:56 Race control will be hoping that the lapping cars will begin to clear water from the track surface.

06:57 Meanwhile, on the circuit three road sweeping trucks are now attempting to remove some of the standing water and excess dirt.

06:58 The drivers are now walking back to their cars and Fernando Alonso puts his helmet on with seven minutes to go before the race resumes.

06:59 The FIA medical car is now going round on a lap of the circuit to check the latest track conditions.

07:00 The safety car remains in position at the front of the field, ready to lead off as the race resumes.

07:00 Alan van der Merwe is at the controls of the medical car and he is pushing as hard as he can to get a read on the grip level, so that he can relay that information to safety car driver Bernd Maylander.

07:01 The drivers are now back in their cars as light rain continues to fall over the Korean international circuit.

07:02 The hooter sounds with three minutes to the restart.

07:03 Hamilton is focused in his McLaren in conditions that could work out well for the 2008 champion.

Lap 4: The race has resumed behind the safety car.

Lap 4: The safety car leads the field down the long straight and there is still an enormous amount of spray being thrown up from the cars.

Lap 4: There is very limited visibility from onboard with the leading drivers.

Lap 4: Hamilton says the conditions are "much better" and he is keen to get up to speed.

Lap 4: The field comes through the twisty section of circuit and towards the end of the fourth lap.

Lap 4: Vettel, meanwhile, is not so keen to race just yet.

Lap 5: The safety car leads down the long back straight into the fifth lap.

Lap 5: Button tells the McLaren team it is a "little bit better but still very wet."

Lap 5: Lucas di Grassi comes into the pits for a change of tyres. He falls back to 24th and last position.

Lap 5: There continues to be a serious lack of visibility from the onboard pictures, even at these slow speeds.

Lap 6: Sakon Yamamoto has been off the track at Turn 5. He continued onto the extra asphalt run-off area but was able to rejoin.

Lap 6: Liuzzi tells his Force India team that the track is so wet on the straight that he can't see the car ahead of him.

Lap 6: The official Formula 1 radar shows that the last of the rain is coming through the area now and that conditions will progressively get better.

Lap 7: Safety car conditions remain, although the circulating cars are starting to clear some of the water from the racing line.

Lap 7: The light appears to be beginning to fade just slightly, although the sunset time is well over an hour away.

Lap 7: Vettel says the water level on the straight is decreasing a little and things are getting slightly better.

Lap 8: Hamilton says conditions are "good" and he is clearly very keen to go racing.

Lap 8: Michael Schumacher slides wide at Turn 3 and onto the extra asphalt run-off area. He is able to continue.

Lap 8: The grip level is clearly non-existent out there, as Schumacher was able to lose the rear of the Mercedes under braking at low speed.

Lap 9: The rain is still falling lightly.

Lap 9: At Mercedes, the mechanics are in the pitlane laying down strips of absorbent material, to make the pit entry for Rosberg and Schumacher as smooth as possible.

Lap 10: The concrete apron in the pitlane has been a concern for the teams all weekend and things could become very slippery when the drivers head in

Lap 10: The rain is beginning to fall a little harder once more. This may delay any decision to bring the safety car in.

Lap 10: The official Formula 1 radar predicts that the rain will stop in around three minutes.

Lap 11: Webber is told of Hamilton's eagerness to race but the championship leader feels conditions are little different.

Lap 11: Vettel leads Webber, Alonso, Hamilton, Rosberg, Massa, Button and Kubica behind the safety car on lap 11 of the Korean Grand Prix.

Lap 11: Alonso is told by the team that Ferrari expect five minutes more rain.

Lap 11: Down the field, two drivers have been into the pits. Senna and di Grassi have been in to change tyres and run in 23rd and 24th.

Lap 13: The procession continues in Korea as everyone waits for race control to decide on when racing can begin.

Lap 13: The standing water and spray being thrown up from the cars is certainly a lot less than when the race originally started.

Lap 14: But there is still a good deal of spray being thrown up, and down the tunnel-like straight between Turns 2 and 3 visibility will be extremely difficult.

Lap 14: Lucas di Grassi comes into the pits for another set of full wet tyres.

Lap 14: Di Grassi rejoins after a total pitlane time of 25.2 seconds. He remains at the rear of the field in 24th.

Lap 14: Hamilton is told of the other drivers' concerns and says "Well it's a wet race. What do they expect?"

Lap 16: Vettel leads the snake of cars into lap 16 from Webber, Alonso, Hamilton, Rosberg, Massa, Button and Kubica.

Lap 16: Hamilton tells the team "it is almost intermediates"

Lap 16: Conditions are brightening overhead, with the band of rain moving clear of the racetrack.

Lap 17: The safety car will come into the pits at the end of this lap.
