The result.
Dry track. Suns out. Not ideal for Hulkenburg then, and sadly he was out dragged into the first corner by Vettel. Webber soon followed and away went the Red Bulls.
Hamilton went wide in turn one and Alonso slipped by for the second time in two races, never to be challenged.
Gradually Hulkenburg slipped back, holding a train of cars behind. Button, back in 11th on the grid, was in the middle of it. lap 12 and he pitted for tyres. a gamble, sure, but why not - at least he could then run at his pace. It worked. Others followed, but he jumped Massa in two laps and eventually emerged 5th behind Hamilton.
So, job done, not much to add - run to the line for 50 laps..........
Then Liuzzi forgot to turn right in turn two and magically turned his Force India into a 3 wheeler.........
Safety car....eek.
15 or so laps to go.
Un-noticed by the commentators, the McLarens could stop for tyres and rejoin without losing places putting them on fresh tyres, however behind about 10 lapped cars. Mercedes did the same, being the only others on the same lap.
So, the last 12 laps would have a chase for Hamilton to Alonso - and Alonso after the Red Bulls.
No drama on the restart. but also no real excitement, Rosberg got back ahead of Schuey. Top 5 stayed as they were to the finish.
So, Red Bull took the Constructors. Alonso still leads by 8 points. Webber needs a win in Abu Dhabi with Alonso 3rd. Should Red Bull have asked Vettel to let Mark through here to narrow the gap to 1 point? Clearly they didn't think so.
7 days until we know.
