Disaster for Daniel Ricciardo! He started 14th but it looks like he gets tagged and is sent spinning off the circuit.
Safety car is deployed.
LIGHTS OUT!
Perfect start by Sebastian Vettel and he is into the LEAD at the first corner.
Everyone in position on the grid apart from Lewis Hamilton, who starts in the pit lane.
The two previous times Valtteri Bottas has started on pole he has gone on to win. Same again today?
Peter Wanyonyi: Woken up by a gentle earthquake in Wellington, slept fitfully after that, up at 4am for the #BrazilGP, external. Congrats to Lewis Hamilton for the 4th WDC, cmon Brendon Hartley.
Sophie: Gcse coursework (not Brazilian) and #bbcf1, external to distract me.
Martin Roberts: I think with little pressure on him, Hamilton will drift through the pack today. I’d say a podium is realistic.
An emotional message of thanks from Felipe Massa over the team radio.
"Thank you for everything you guys did for me," he says. "I love you guys."
Looks like all OK with Kimi Raikkonen's car. He's sat in it now and ready for the formation lap.

Lewis Hamilton, starting in the pit lane, has soft tyres on his car, as do Pierre Gasly (19th) and Marcus Ericsson (17th) and Daniel Ricciardo (14th).
It looks like BBC Sport readers agree with Toto Wolff with 59% of you expecting him to get into the points but not on the podium.
Right then. On with the race. Just two minutes to go...
Mercedes' team boss Toto Wolff is asked by 5 live's Tom Clarkson what result Lewis Hamilton can achieve from the back:
"I think without a safety car, P4 is the optimum result. The big problem for us is the temperature is 10C hotter than Friday and on our car the tyres are Swiss cheese - it melts."
Lewis Hamilton has scored points in 23 consecutive races - four races short of the record set by Kimi Raikkonen in 2013.
He has plenty of work to do today to keep his run going but he has fought through the field to clinch a place on the podium in Brazil before. In 2009 he started 17th and finished third.
Kristine Kirby: Possibly the strangest thing I have seen in weeks is the grid image. But, with Lewis having a new engine, and being angry at himself, he's got nothing to lose, I expect he'll be punchy moving up the field. Might get on the podium, if the tyres can handle the heat.
Uh oh! It looks like there's problems for Kimi Raikkonen. There's lots of work going on his car with just minutes to go until the grid is cleared for the formation lap...
Fernando Alonso, who is starting sixth in the McLaren, is asked whether he's targeting a podium finish.
"We'll see. There are some fast cars behind us but we will try to defend and do our best," he tells BBC Sport.
Felipe Massa has already been struggling to hold back the tears as he prepares to take part in his home race for the final time.
A lovely moment for the national anthem as Felipe is joined by his son.

The risk of rain is 0%, unsurprisingly.

It’s looking very much like a one-stop race, with the super-soft on which most of the runners will start projected to last 35 laps - about half the race - and a one-stop predicted as the fastest strategy. The heat, though, could change things. It is mid-20Cs and track temperatures are projected to reach as high as 55C. That could increase degradation and push teams towards a two-stop.
