A tyre delamination during second practice meant that Marussia’s Max Chilton couldn’t get a run on the option tyres.
Chilton was twenty-second quickest during the session.
“Today hasn’t been the most straightforward of days but I know from experience that this circuit presents a variety of challenges, so not entirely unexpected,” he said.
“We have had our frustrations in a few areas but we’ve made some progress and completed some good runs – unfortunately not my new option run. I’m looking forward to seeing how the rest of the weekend will shape up now. The rain looks sets to play its part – that much looks clear. The rest is a little open right now so I think we will see an interesting qualifying and race.”
Team mate Jules Bianchi was eighteenth quickest, just 2.9s down on Kimi Raikkonen’s time.
“I’m happy with the work we have been able to complete today, but it’s always difficult to end Friday without a clear picture of where we stand and where there are still so many variables to consider,” he said.
“I am pleased with my performance today though and we seem to be making progress on the set-up we need here. This is just one of those races and circuits and it’s the same for every team. It’s my first time racing here and I am happy with the way I have acclimatised to the track. Now we have to see what the rest of the weekend holds. It could be frustrating, it could be exciting. We will see.”
