Paul Hembery: “Together with Red Bull Racing, we’re still examining the remains of Sebastian Vettel’s tyre in order to try and piece together what happened. It certainly seems to be a very unusual incident and we’ve already been to look at the place with Sebastian: there seems to be no reason that is immediately obvious and the set of tyres was one that he had already used for qualifying.
“But until we know for sure, there’s no point in speculating. With the dropping temperatures, our soft and medium tyres were faced with slightly different track conditions to normal, with different teams trying a very wide variety of strategies, from one to three stops.
“I’ve been told that last year there were just 11 overtaking manoeuvres here, so this year certainly presented quite a contrast. Normally at this point we would be packing up to go home, but now we look forward to the young driver test later this week, where we will try out some of our 2012 range of tyres for the first time.”
