Brazil Saturday quotes: Red Bull

David Coulthard - 14th: "I'm not really happy with that as my last F1 qualifying session. We went reasonably well here last year and got into the top ten, so we came here thinking that might be possible again. But, in the end, we didn't manage to find enough grip in the middle sector. We are reasonably competitive in the first and last sectors, but in the middle we're struggling, as the rear has been sliding, which loses us lap time, The tyres suffer a lot with graining here on the longer runs, we were hoping to keep it together for one lap and then do what we could in the race. Let's see what we can do from there tomorrow."

Christian Horner: "After being competitive in yesterday's practice and this morning, to qualify 12th and 14th is obviously disappointing. As the temperature has risen we seem to have been adversely affected. But, tomorrow is going to be an interesting race potentially with unpredictable weather and there's a lot up for grabs, so the weekend's not over yet."

Fabrice Lom, Renault, Principal Engineer, Track Support: "We have just lived a very special moment, David's last qualifying session in a Formula One car. David is a real Formula One legend. He started his career with Renault and is ending his career with Renault and it's been a pleasure and an honour to work with him for those years, so thank you to him. Having said that, F1 is a cruel world and even though it's DC's last race, other teams didn't give us a gift today. We're 12th and 14th, so it will be a tough race tomorrow."
