Spa, Monza, Singapore, Yeongam, Suzuka, New Delhi, Abu Dhabi. Seven venues. Seven victories. Can Sebastian Vettel set a new Formula One record and win eight races on the bounce? Welcome to LIVE coverage of the United States Grand Prix from Austin, Texas.

Down in the mid-pack, former champ Button is sliding around the track and really struggling for grip. He'll be coming in soon, from 13th place.

Solid pass from Rosberg as he pops his Mercedes past Ricciardo and into the points.

Vettel being told to slow down by his race engineer. You wonder if he's even trying? It's so easy for the German, but also very impressive. The question is: will he be considered a true great if he continues to win by miles in the fastest car? Not much he can do to change the other cars, but it would be great if the other garages can get a move on. Obviously...

Back on the radio, Hamilton (4th) announces: "I've got no grip. I'm trying, man, I'm trying".

Was meant to be a special weekend for Button who equals David Coulthard's British record for most F1 races. But fighting over 13th with Massa probably isn't the way he wants to celebrate.

Vettel's lead is now above five seconds from Grosjean with Webber a further six second back. Further down the field, Button has a sneaky look at Massa but can't make the pass.

"You just need to manage your position" announce team Mercedes on the radio. "I'm trying to" is Hamilton's retort.

Hamilton gets a little tetchy with his team on the radio. The Brit must lose concentration as he fails to prevent Webber flying around him into third.

Quite a nice train of cars from fifth to seventh... Hulkenberg, Perez, Alonso. Great drive so far from Perez after being dropped by McLaren. He's way clear of teammate Button.

Vettel's engineer: "Sebastian, your pace is good." I could have given that advice. Alonso has a little look down the inside of Perez but quickly puts the brakes on as the McLaren swoops across his path.

Bottas looking decent in the earlier stages. He sits in eighth, nicely in the points, just behind Alonso.

No graphic for this, but the stewards see fit to wave a black and orange flag at Maldonado. The Venezuelan pops into the pits to fix his car and rejoins near the back.

Vettel is flying and has opened up a sizeable advantage already. Looks like we'll be talking about race win number eight.

Hamilton is struggling out there with the ominous sight of Webber in his rear-view mirrors. The Brit holds him off, for now.

Max Chilton gets on the brakes of his Marussia to bring his car down to pit lane speed. He serves his drive-through for impeding Maldonado in Q1 yesterday.

As you'd expect, Vettel nails the restart and quickly pulls clear of Grosjean and Hamilton who are squabbling over second. Less drama this time around although Perez threatens to go around the outside of Hulkenberg before thinking better of it.

Super work from the crane crew - a far cry from the antics in free practice two of the tractor that got stuck in the gravel - who quickly clear Sutil's wreckage. Shouldn't be too long before we're back racing. Quick shout out to Hamilton who jumped from fifth to third on lap one.

Looks as though Sutil collided with Maldonado, but on second viewing it does look like it was the German who caused the crash. Maldonado is fine to continue, albeit he's down in 17th.

Vintage start from Vettel, who had opened up a good two second lead but he must now allow the pack to regroup whilst the marshalls clear the track.

CRASH! Adrian Sutil gets clipped and is sent sprawling into the barriers. His Force India takes a fair thump but he's out the car and moving. Safety car is out.

GO GO GO! Great start from Grosjean who moves past Webber into second. It's a terrible start for the Aussie who has dropped into fourth.
