In BMW-Sauber are determined to make further progress after the aerodynamic changes made at the recent Spanish Grand Prix. The German team has not yet played a role as leader in 2009, but the boss Mario Theissen has insisted that in Barcelona there were signs of recovery after the terrible situation of the first four races.The double-deck diffuser which has not been part of the package for Spain, will be introduced in their cars from the Grand Prix of Turkey.
"To be honest, I look forward to Istanbul," said Nick Heidfeld, who celebrated his birthday by taking two points in Spain. "In Turkey we will have new package of aerodynamic parts. I hope that we will have many points in future, "added the German.
Also in Istanbul BMW plans to reintroduce the KERS, system which they didn`t used in Spain and they didn`t plan to use it and at the weekend in Monaco. From Turkey they will use KERS completly redesigned, nothing similar as old one.
