Kubica feeling confident

Polish driver eyes further improvement

Robert Kubica is confident BMW can improve even further this season.

The Hinwil-based outfit are having one of their best seasons to date and are currently second in the constructors' championship behind Ferrari.

Kubica is sitting pretty in fourth place on the drivers' standings after picking up two podium finishes and two back-to-back fourth places in the first five races of the season.

But the Polish driver believes there is room for improvement at BMW.

"We need to work in all areas because, in the end, it is the 'package' that makes the difference," he told the official Formula One website.

"I know that the team is working hard in order to find the improvements that we need and I am sure that we still have space for a step forward."

Kubica also played down suggestions that the reasons he is out-performing team-mate Nick Heidfeld is because he has a better car.

"I don't think that it's a question of car," he added.

"I'd rather consider the fact that I now have one more year of experience and that I am working very well with my new race engineer, Tony Cuquerella."
