Vettel returns his car to parc ferme. A fantastic win for him and also by Grosjean who took a very valuable 18 points for Lotus.

Apologies, Lotus is 18 points shy of Ferrari so third place could be within range in Brazil. It should be interesting but Lotus will still need Kovalainen to perform.

The German national anthem rings out over Austin as Vettel soaks it all in on top of the podium.

Thanks for joining us this weekend. The Vettel win has looked locked on all along, but still a very impressive achievement nonetheless. We'll be back in just one week for more live commentary from the Brazilian Grand Prix and the final race of the 2013 season.

Lap 56

Vettel wins the US Grand Prix at a canter. Grosjean holds on to second. Webber takes third.

Hamilton keeps fourth place, not bad from him and Alonso fends off Hulkenberg for fifth.

Gutierrez has a last lap spin after contact trying to pass Vergne for 12th.

And here come the doughnuts on the exit of the hairpin. "We have to remember these days" Vettel says after breaking the record for the most consecutive wins in a season.

Bottas takes his first points in eighth. Great weekend for him.

-------------------------------------------------------------------------------------------

Vettel on his final lap now and cruising to victory.

Hulkenberg passes Alonso into Turn 1, but the Ferrari is wary to that, takes a wide line, gets better traction and retakes the position on the exit of the corner.

Lap 55

Vettel sets a new fastest lap, but is warned he is the only person who can beat him today.

The closest battle in the points is for the final one with Button 0.8s behind Ricciardo and attempting a pass right now.

Button passes on the inside of Turn 1 to take the final point. As Hulkenberg attacks Alonso in the final sector of the penultimate lap.

Lap 54

Grosjean appears to have Webber beaten. He's now 6.3s off Vettel now but the lead Red Bull only has to nurse his car for another three laps.

Alonso's challenge on Hamilton has gone off the boil. 2.9s the gap now and Hulkenberg 1.2s off the Ferrari.

Lap 53

Grosjean sets the fastest lap of the race and still has tyres left to push. This has been a fantastic race by him. More proof that he is ready to lead Lotus into 2014.

Webber really struggling now as he loses the rear end in the hairpin. He's told to use KERS out of the final corner, but he's nowhere near close enough now.

Lap 52

Webber remains on Grosjean's gearbox. Webber is told to use all of his KERS on the back straight to try to pass after getting closer on that last lap.

But he's nowhere near close enough on this lap. He looked like he was struggling with traction out of the hairpin, so Grosjean might just have him beaten.
