Brazil Saturday quotes: Red Bull

"Both cars are in a reasonable shape and we've been competitive all weekend. So, so-far-so-good and we'll see what we can do tomorrow."

David Coulthard - 9th: "The option tyre at the beginning of that qualifying session felt really strange, I struggled on it, made a few mistakes and couldn't get it together.

"I then managed to on my last flying lap, which got me through into the top ten. There was a very slight under fill when the team did my refuelling, so I had to try and do the laps without burning all the fuel, but we managed it okay."

Christian Horner: "Another very strong team result clearly showing the progress that we've made during recent weeks.

"Fifth and ninth with the cars on different strategies for tomorrow is a good position for us and we'll be fighting hard to try and achieve the five points we need to overhaul Williams in the Constructors' Championship."

Fabrice Lom, Renault, Principal Engineer, Track Support: "We are very pleased with our performance today. Our package was very strong from the start of qualifying, our drivers managed to do a good lap in Q3 and the result is really encouraging for our race tomorrow.

"The competition is really close on this track and the engine has a real role to play in those circumstances. Both our drivers have a fresh V8 for this weekend and we will push as hard as possible to get the most out of our package and try and take fourth place in the Championship."
