Alonso11:45 Hello everyone and welcome to AUTOSPORT Live for coverage of round 10 in this year's FIA Formula 1 world championship - the German Grand Prix from Hockenheim.

Fernando Alonso starts today's 67-lap race from pole position after coming through yet more weather chaos. Alongside him on the front row is Sebastian Vettel, but there was consternation in the paddock this morning, as both he and team-mate Mark Webber's participation in the race was thrown into doubt, following a stewards investigation into the legality of the RB8's engine mapping.

After more than two hours of deliberation and intrigue, the stewards decided that the team has obeyed the ECU regulation to the letter. While the stewards indicated that they weren't completely satisfied with the explanation from the team, ultimately no penalty will be imposed.

No further action taken over Red Bull

So Vettel keeps his front row position, with Michael Schumacher and Nico Hulkenberg pulling out sensational performances in qualifying to make it three Germans in the top four at home. Spanish Grand Prix winner Pastor Maldonado is a fine fifth on the grid, followed by McLaren drivers Jenson Button and Lewis Hamilton.

11:46 The crowd rises as the German national anthem rings out over Hockenheim.

11:47 Here's how the standings look as the season reaches the half way stage:

11:49 What a change 24 hours makes. It has been fine, dry and mainly sunny so far today and this trend will continue into the race.

Air temperature is up to 20 degrees and, with continuing sunshine this afternoon, we may see track temperatures nudge through the 30 Celsius barrier during the event.

A light north-easterly breeze will keep the spectators cool this afternoon, but the action on track should be pretty hot.

11:50 Lewis Hamilton readies himself on the grid ahead of a 100th start for McLaren. He is lines up seventh in an upgraded MP4-27.

11:51 With several penalties being applied, here's how the shuffled grid will line up this afternoon:

11:51 Raikkonen's Lotus crew is being told to be very careful not to reveal the starting choice of tyres.

Tyres11:53 Preparations for this race have been seriously hampered by rain, with limited dry running during practice meaning teams don't have the usual pre-race knowledge of how the tyres are likely to perform on Pirelli's debut at this circuit.

Soft and medium compound tyres are on offer, with the wet qualifying session meaning drivers have a free choice of starting rubber. That opens the possibility of contrasting strategies, with some outfits surely eying a start on the harder tyres and seeing how far they last before a switch to softs when the track improves.

Wear rates could turn out to be high - with temperatures much warmer today and rainy practice days meaning limited rubber remains on the track surface.

11:53 Button lines up sixth in his updated McLaren, which did appear to have promising pace during the limited dry running on Friday.

11:54 Alonso's steering wheel is fitted and the championship leader is ready to lead the cars away from his second pole position in as many races.

11:55 Just five minutes to go until the formation lap begins at Hockenheim.

11:55 Michael Schumacher is advised of a choice of differential settings for the early stint of the race, on the Mercedes team radio.

11:56 One DRS zone here, detected after the second complex of corners before allowing the wing to open down the curving stretch to the hairpin.

11:58 Soft tyres looks to be the choice of the field for the start as provisional data comes in on the initial selection.

Lap 25: Alonso's pace isn't as strong on these harder tyres, with Vettel now back to under two seconds behind the Ferrari.

Lap 33: Vettel sets the fastest lap but it doesn't last long as Button goes quicker in 1m20.340s.

Lap 33: Petrov follows team-mate Kovalainen in one lap later.

Lap 34: Hamilton is lapped and soon advised over the team radio that Button in third is just a few seconds behind him.

Lap 35: Hamilton has found some speed after his second stop and tows up behind Vettel and unlaps himself from the Red Bull!

Lap 35: Vettel is not happy about that one, with Button quickly closing on the Red Bull.

Lap 36: Alonso is just ahead of Hamilton, as the Briton now sets the fastest lap of the race - 1m20.091s.

Lap 37: Schumacher is in for a second pitstop.

Lap 41: There's a scramble in the pits as Alonso and Vettel rush in for a stop.

Lap 48: Jean-Eric Vergne pits from 14th place in the Toro Rosso. This is his third stop of the afternoon.

Lap 58: Hamilton pits the McLaren from 16th position and drives straight into the garage, ending an unsatisfactory day for the British driver.

Lap 59: Lots of marbles building up off-line as the tyres wear significantly on a warm day in Germany.

Lap 60: Rosberg remains in 10th spot. He is dropping di Resta, but he is unable to make any inroads into the 6.7s deficit to Hulkenberg.

Lap 60: Both Saubers, traditionally kind on rubber, continue to lap quickly in fifth and sixth. Schumacher is only slowly gaining on Perez currently

Lap 66: Vettel tries the DRS move on Button and makes it stick with some fine driving around the outside of the McLaren.

Lap 66: Developing scrap for eighth in the final stages. Webber now has Hulkenberg 1.2s behind him, with Rosberg a further 1.8s back in 10th.

Lap 66: Alonso heads into his final lap in the lead at Hockenheim.

Lap 67: Button complains to his team that Vettel completed his pass off the circuit.

13:34 Fernando Alonso wins the German Grand Prix!

13:34 Vettel grabs second place at the end from Button to take vital points on home soil.

13:34 Button ends up third after a fine drive in the upgraded McLaren, which does look to have much more competitive pace here.

13:34 Raikkonen finishes a distant fourth for Lotus, with spurts of pace but ultimately not enough to fight for the win.

13:35 A strong fifth for Kobayashi, backed up by team-mate Perez in sixth on a fine day for Sauber.

13:36 Michael Schumacher claims seventh in front of his home fans, with Webber eighth, Hulkenberg ninth and Rosberg gets the final point.

13:36 Out of the points, di Resta came home 11th ahead of Massa 12th, Ricciardo 13th, Vergne 14th, Maldonado 15th and Petrov 16th.

13:37 Replays show Vettel was fully off the circuit as he used a wide line over the run-off to make his way past Button.

13:37 Senna crossed the line just 0.5s behind Petrov in 17th spot, with Grosjean 18th, Kovalainen 19th, Pic 20th and de la Rosa 21st.

13:38 Glock came back past Karthikeyan in the final few laps of the race to finish 22nd, leaving the Indian as the final finisher.

13:39 Lewis Hamilton was the only retirement of the race. His day started badly with a puncture and never really got any better after that.

13:39 Hamilton did at least have some mid-race fun, mixing it with the leaders as he tried to unlap himself, before eventually retiring.

13:39 A time penalty could be handed to Vettel if stewards decide that overtake on Button was outside the rules.

13:40 Vettel tells Button he didn't know where he was as the pair continue to debate the move behind the podium.

13:41 The top three drivers walk out onto the podium and the Spanish national anthem rings out for this afternoon's winner - Fernando Alonso.

13:42 That is followed by the Italian national anthem for today's winning constructor - Ferrari.

13:43 Fernando Alonso collects the winning trophy on another great day for the Spaniard.

13:43 Ferrari technical chief Pat Fry picks up the constructors' prize.

13:44 Sebastian Vettel receives his award for second place, to a huge cheer from the home fans.

13:44 Third place for Button - for the moment - but he will still be happy with a much-improved McLaren performance.

13:46 Niki Lauda is on hand to interview the podium trio as the crowd spill onto the front stretch at Hockenheim.

13:48 Alonso's third win of the year puts him 34 points clear in the title race, with Webber now just two points above Vettel after a tough day.

13:49 Raikkonen is now fourth in the standings, pipping Hamilton who had another disappointing afternoon.

13:50 Red Bull still has a sizable lead in the constructors' race over Ferrari, with McLaren taking third place back from Lotus after a better day

13:51 Stick with AUTOSPORT for all the reaction from Germany, including news of that stewards' inquiry into Vettel's late move on Button.

13:54 Fernando Alonso continues his great summer run of podium finishes and claims another win to extend his championship lead.

His race was shaped with a brilliant start off the line. He left Vettel standing on one of the shortest runs to Turn 1 of the season, but it would be foolhardy to say he never looked back after that. The Spaniard was under all sorts of pressure during the race from the Red Bull driver and Jenson Button. Even the lapped Hamilton got in on the act during an entertaining middle segment.

Another great day for Ferrari, but Sauber will also be very pleased with a strong haul of points for Kobayashi and Perez, while Webber and Hulkenberg will reflect on what might have been. As for Hamilton, a poor start never got any better during the rest of the afternoon and he is falling away in the championship race.
