Spain Sunday quotes: Red Bull

"We've made more progress than any other team since the beginning of the year and when you're aggressively attacking lap times, sometimes you have to put other areas of the car to one side. That's the growing pains we're going through at Red Bull Racing at present, but I think everyone agrees we'd rather have pace and show we're genuinely quick - and then work on reliability, than have a reliable car that only finishes tenth."

Mark Webber - DNF: "Unfortunately reliability problems cost me a race finish today. At the moment, I think it's a recurrence of yesterday's hydraulic problem. We had planned to go for a long first stint because of my low grid position, but it doesn't matter what strategy you have if you don't get to the finish.

"There's not much more to say except for the obvious fact that it's disappointing. But, at least David's great result and finish in the points proves that the car has the pace to do well. It's a great boost for the whole team."

Christian Horner: "David was exemplary today. He had good pace, a good start and a good strategy. Despite a problem that gave us all a bit of a scare in the last three laps, he found a way to drive round it by using all his experience. He was able to bring the car home in fifth position and get us onto the scoreboard. I'd like to acknowledge the huge effort made by the whole team.

"Everyone's been working hard over the last few weeks, but we still need to keep pushing. It's disappointing that we had a repetition of yesterday's transmission failure on Mark's car. He's had miserable luck all weekend, but I'm sure he'll bounce back in Monaco and we can head there optimistic, in full knowledge that we've made a good step forward in pace here this weekend."

Fabrice Lom, Renault Principal Engineer, Track Support: "We are very pleased with today's result. We scored our first four points of the season and showed that our package has real potential. The engine worked perfectly and its good qualities in low revs even helped compensate for David's gearbox problem in the late stages, and helped him to defend his position.

"In spite of Mark's unfortunate retirement, we showed today that we have nothing to envy our direct competitors and that we have genuine potential, which is very encouraging for the coming races!
