Kubica vows to keep aggressive approach

The Pole is just two points adrift of the lead of the drivers' championship, with the consistency of his BMW Sauber team paying dividends against what many perceive to be quicker McLaren and Ferrari cars.

And although Kubica's best hope of clinching the title this year will come through a regular haul of points, he has made it clear that he will only worry about the championship in the final races of the season.

"My approach is very similar to what it was before," Kubica said at this week's test in Hockenheim. "In fact, it is exactly the same.

"I am trying to achieve as many points as possible for each weekend and extract as much as I can from the car. If the maximum can be achieved and it is good enough to win the championship in the last race, then you think about the championship then. But right now, it is a race-by-race approach."

Kubica believes a clearer picture of how the world title battle will develop will emerge over the next two races in Germany and Hungary - with form having been so difficult to judge in France and Britain.

"Looking at the last two races, they were completely different races," he said. "In Magny-Cours Ferrari were much quicker than everyone else and in Silverstone they were much slower than everyone was expecting. McLaren were the complete opposite, slow in Magny-Cours and very quick in Silverstone.

"I think in qualifying in Silverstone we were more competitive than we expected to be, so we have to see. Silverstone I will not take much into consideration because it was quite a strange weekend, we have to see now in Hockenheim and Hungary how things will develop before the break."

And he sees no reason why, with most teams enduring up and down fortunes, BMW Sauber cannot overcome the challenge of McLaren and Ferrari.

When asked if he felt his team's consistency would be good enough to win the championship, he said: "It depends. It depends on the others; at Silverstone for example it was a good example.

"Some teams were struggling more and to be honest I was not expecting to be two tenths off the fastest time in Q2. In Q3 unfortunately I did not have any lap time and had to start from the back, but it was a good opportunity.

"It is difficult to say, but all teams are trying to start the season with the right speed and right approach and nine races is a good representative number to see how competitive you can be."
