Sutil: Improvements will take time

Sutil and team-mate Giancarlo Fisichella have failed to score a point or make it out of Q1 in the opening two races of the season, but the German is confident that the car will be improved significantly in the coming races.

"There is potential in this combination," Sutil told AUTOSPORT. "It's a difficult situation because there was not much testing as we built the car in about 120 days, so it's hard to pick up.

"We have a lot of things going on in the windtunnel and it looks promising. The question is whether it is enough to make steps because the others are not sleeping, they always develop.

"But I am confident. Right now I am quite happy that the car is working well. There are no reliability problems and that helps us a lot, we need mileage to understand the car."

Sutil, who narrowly missed out on a points finish with ninth place in Australia, believes that the spirit inside the team is better than it has been since he joined as a race driver at the start of 2007.

"There is a very positive spirit," Sutil added. "The atmosphere is good and that's why I'm very happy now. There are no problems in the team and that makes it stronger."

"It's always good if you feel good in a team. If there are some problems, yes of course you will start arguing and that doesn't help.

"But the baseline is very good right now. That means you can develop yourself well and have success more easily."
