Mark Webber said that, although his Red Bull team had a bit of a challenge setting up the car during Friday practice in Brazil today, he was pleased with how things had gone.
The Australian, who won this race two years ago, topped the timesheets in the morning session, and was third fastest in the afternoon.
“The track is hot, not super hot in terms of ambient conditions, but the track is very warm and it's humid too,” he explained. “It's also pretty windy, so it wasn't the easiest day to get the car dialled in and balanced, but clearly it was the same for everybody.
“I think we had a pretty good day; there are lots of sets of compounds to go through, as it might be the last time we get to run in the dry as there's potentially some wet weather coming – but we had a good day.”
Team-mate Sebastian Vettel ended the day second fastest, behind only Lewis Hamilton. He still thinks that there is room for improvement this weekend.
“I think we were able to improve the car throughout today, but we definitely need to make another step,” said the world champion. “It was hot today and the circuit was slippery, although rain is forecast for the next two days, so I think the conditions will change.
“We're all here to win and it would be great to finish with a good race, but it's a long weekend ahead and a lot of things can happen. It's a challenging track and we all like coming here, it's a good grand prix.”
