Theissen thrilled with first half of '08

BMW Sauber are currently in second place in the constructors' championship, having scored seven podium finishes, including a one-two at Canadian Grand Prix, where the Hinwil-based squad scored their maiden F1 victory.

Pole Robert Kubica is just two points behind the championship leaders, with teammate Nick Heidfeld ten points adrift.

And ahead of their home grand prix in Germany next week, Theissen admitted it was hard to predict such a successful season.

"It would have been difficult to come up with a better script for the German Grand Prix held in two weeks time at Hockenheim," Theissen wrote on his team's website.

"We wanted to turn the duel on the front end of the field into a battle of three and win our first race. We succeeded in doing so. From now on, our goal always will be the forthcoming race. And when the season is over, we will see what we have been able to achieve.

"Regarding the lap times, the two teams still are some fractions faster than us. But when it comes to the reliability of our cars, the work of our pit crews and the race strategies, we also represent a top team.

"I'm particularly delighted with the fact that we not only succeeded in realising all our goals early but also progressed consistently. This is confirming that both our strategy and direction are fine."
