Nico Rosberg has already surpassed his points total from 2006 with a fighting drive to sixth place in the Spanish Grand Prix, the German producing one of the drives of the day from eleventh on the grid.

Adding to the seventh he gained in Melbourne, sixth place actually marks Rosberg's best ever result in Formula 1 and it helps lift Williams to fifth in the constructor standings, despite team-mate Alex Wurz retiring on the first lap.

Getting a strong start to move up to ninth by the end of the first lap, Rosberg managed to pick off retirees Kimi Raikkonen and Nick Heidfeld to move into seventh, while fuel rig issues for Heikki Kovalainen helped him jump into a net sixth place.

Holding on to the finish line, Rosberg very nearly converted sixth to fifth in the closing stages when David Coulthard up ahead began to slow with gearbox problems. Although unable to quite catch the Scot before the chequered flag fell, Rosberg was nonetheless happy to maintain his competitive start to the season.

"It was a good race and there's no doubt we got the balance right, especially in the middle stint, when I was really able to push on fresh tyres. Thanks to the team for the strategy and the perfectly timed pitstops. My only problem was that my drinks' bottle didn't work and I couldn't take in any fluids during the race at all so it was really tough, not just because I was thirsty, but in terms of concentration, especially towards the end.

"This is the best result I've had in F1 so far, and that's a great feeling. Trying to catch up with Coulthard at the end of the race was exciting, but I really needed a couple more laps to get him. Three points are great and I am happy that everything came together for us today."

Wurz meanwhile was caught out on the opening lap when a chain reaction brought on by Giancarlo Fisichella overtaking Anthony Davidson caused the Austrian to hit the back of Ralf Schumacher hard, destroying his front-end

Despite another performance that leaves him without a point to his name, Wurz is nonetheless confident ahead of his 'home' race at Monaco where he will be returning to his place of residence for the fifth round of the season.

"A short race, and really just not the best weekend for me. I had a good start and overtook a few guys, but then I was lined up behind Ralf going into turn 10 and he suddenly had to lift for someone in front. It's such close racing out there so I had zero chance to react and ended up on his wheel. It proved the end of my race. I'm disappointed that I could not show my race pace, but you can count on me in Monaco."
