Romain Grosjean moves up to 11th with an overtake on Brazilian Felipe Nasr and is putting the moves on Max Verstappen. Meanwhle, Nico Rosberg has opened up 1.3 seconds on his team-mate Lewis Hamilton.

Fernando Alonso had to go into the run-off on Turn Two after the green light.

That's Daniel Ricciardo in the pits early doors. Not exactly what you need when you've started 19th on the grid.

"It was not a bad start from Lewis Hamilton but Nico Rosberg aced it. Hamilton came in behind Rosberg, picked up the slipstream and then tried to get around the outside."

A look back at that start then. Lewis Hamilton swung in behind Nico Rosberg and then slingshotted on the outside into Turn One. Nico had just enough though.

Behind them, Valtteri Bottas moved up a spot by going past Nico Hulkenberg - he almost hauled in Kimi Raikkonen too.

"You can see the black lines on the track, whatever the issue Carlos Sainz had it has seized the rear end. Part of the car is still on the track and they may well have to put out the safety car."

Lap 2/71

Carlos Sainz makes his own lonely start from the pits and moments later he's on the side of the track. It seems his rear axle has locked up and that brings out a yellow flag in the second sector.

Lewis Hamilton has a go straight from the line but Nico Rosberg holds him off. The top five maintain their places through the first two turns.

And we're off!

Everyone apart from Carlos Sainz is out on the formation lap - and now they get lined up.

"I'm looking at Carlos Sainz's car now. He is sat in the garage and a race against time to get him ready for the start. They have had four goes at starting his engine and it keeps cutting out. It cut out when he did a practice start and the team is still scratching their heads now."

Lewis Hamilton has spoken many times of how Ayrton Senna is his inspiration.

But he is still yet to win in the homeland of his hero. He will look to change that in two minutes.

It took him eight attempts, but Ayrton Senna finally won in Brazil in 1991.

And he did it with a dodgy gearbox and a dodgy shoulder. What a guy.

“Within Red Bull, there were never very high hopes for the upgraded Renault engine that has been introduced this weekend. Renault has promised it would give about 0.15 seconds in lap time, but in fact Daniel Ricciardo, who is using it, was slower on the straights with the same downforce levels, as team-mate Daniil Kvyat, who is not and was 0.095secs slower as a result. It turns out the engine actually has less power than the old one. Renault are saying to Red Bull it is not optimised yet, and the guidance is that it opens up development opportunities for 2016. But it has escaped no-one that, just as the beginning of the season, a supposed improvement in the Renault has actually led to a drop in performance.

“Using it has meant Ricciardo takes a 10-place grid penalty. Did the engine have any benefits at all? ‘If I’m honest, no,’ he said. Was it worth it? ‘For the grid penalties no, but for us, getting some clarity on where it is, yes. We have seen it hasn't really given us anything, so back to the drawing board for Renault. We have to try and find some more from it but I don't regret testing it because we had to try. We had to see if there were any positives from it and if what they saw on the dyno was replicating what we felt on track. In hindsight, it didn't give us any lap time, it's just for now a penalty for a little bit of knowledge.’

“For the rest of us, at least we now get the pleasure of watching Ricciardo trying to slice through the field in the race.”

Toro Rosso's Max Verstappen, starting from ninth: "It will be very hard for the tyres, it will be difficult to see how many stops we have to do, between two or three but it will be a tricky race to manage the tyres for sure. We will try for two stops, but we have to anticipate what the others are doing."  

There's quite a buzz around Toro Rosso's Max Verstappen right now. Yesterday, Eddie Jordan predicted he would be joining Ferrari within two years.

A lot of you enjoyed the Dutchman's interview with our very own David Coulthard. Feel free to watch it again right here.

Or, if you have never seen it before, you can watch it right here.

(They're both the same link, obviously).

Carlos Sainz has been towed back to the garage. Reminds me of the time my Ford Focus had to be towed off an embankment after I turned on the ignition with it in gear.

Anyway, the Toro Rosso will have to start from the pit lane.
