Red Bull Vow to Find More Speed

Vitantonio Liuzzi and David Coulthard could manage no better than 11th and 13th places respectively with neither driver having the pace to challenge the cars ahead.

With the start of the European season signalling the beginning of major development programmes, the team need to make improvements if they are not to lose further ground to their opposition.

Christian Horner, Red Bull's sporting director, said: "Obviously 11th and 13th is pretty disappointing after three consecutive point-scoring races.

"Tonio drove an excellent race on his Grand Prix debut. He was consistent throughout and made a very solid start to his F1 career.  David had a couple of knocks from Massa and I think this damaged his car slightly. 

"From  a reliability point of view we're Ok, but we need to take a step forward in performance. We hope to see that at the forthcoming test in Jerez."

Coulthard's race was badly affected by two collisions with the recovering Felipe Massa, one of which damaged his car.

"At the start I was a bit slow away from the grid. I was running around okay but then had a bit of a bump with Massa, which broke part of the floor," said the Scotsman. "We went backwards from there and never really came  back.

"The race was pretty lonely actually, just going around in circles. The car didn't have great race pace - we knew that from yesterday - so I was expecting to struggle a bit. But I still thought I'd have a better balance than I did. There was a lot of oversteer."

Liuzzi, who was making his F1 debut, said after his race: "I thought the race would be difficult for me because of fitness, but I feel pretty okay.

"The car was quite good really. The balance was good, but there just wasn't enough speed, so we have to improve .It was quite difficult to keep the car on the track - it felt as if I was sliding all over the place. I wanted to overtake Mark (Webber), so I tried to make something crazy but it didn't work. Can I say that?

"It feels great to have done my first race and I can't wait for testing to prepare for Barcelona."
