It is not sure that a ‘double diffuser’ solution will be equipped to be contributed to the 2009 BMW-Sauber package for this weekend’s Spanish grand prix. Mario Theissen the team boss stated that “Whether it will be there or not is not yet definite.”
Sport Bild says that architects had devised a double diffuser for the single seater, but simulations from the computer brought up doubts about its effectivity.

The drivers’ teams which includes Robert Kubica, and who has not yet scored a single point, are not hopeful.
The Pole informed the publication that: “We will make a step forward in Barcelona, but whether it will be big enough is improbable.”
Teammate Nick Heidfeld added: “We did the first four races without big changes on the car, while the other teams constantly had new parts and went further ahead than us.”
