Rosberg says there's more speed in FW30

Rosberg and teammate Kazuki Nakajima had a troubled Friday, both hindered by gearbox problems that meant they lost valuable track time.

Despite that, Rosberg put on a solid performance, qualifying in seventh place, although the German reckons there was some more speed to be found in the car.

"I am pretty happy with today's qualifying as we very nearly got the best out of it," said Rosberg. "I felt that coming here would be fantastic as I hoped we could be the best of the midfield and so we measured up against this expectation.

"We had a difficult start to the weekend yesterday and we didn't show what we are capable of, and we still have a little bit to come.

"So, overall, I am happy and we have a really good position for tomorrow to try and score some points. It's going to be a tough race though for all the cars and I am sure there will be a few problems up and down the field, but I am confident we'll do okay."

Nakajima, in only his second Formula One race, qualified down in 14th position and the Japanese admitted he was not happy with the result.

"It was not the best result from qualifying, but at least I took one more step forward from my debut race last year by making it through to Q2," he said.

"It was more difficult this time round because of the red flag, but it was important for me to take it steady today and trying to find the extra lap time to make it into Q3 would have been quite tough. I'm looking forward to tomorrow."
