BMW Will Not Debut Double Diffuser in Spain

BWM Sauber will not debut their own-developed version of the double diffuser in Barcelona. Although the Hinwil based team have announced a major update of their aerodynamic package for the Spanish Grand Prix, the aforementioned feature will only be introduced to the F1.09 during the Monaco Grand Prix the soonest.

As argued by BMW motorsport director Mario Theissen, the double diffuser was not initially planned to be part of the car's European package, as it was only ruled by the FIA during the course of last month. Of course, that doesn't mean BMW did not proceed to developing the feature through the past few weeks, but only that introducing an interim version of it would prove inefficient within the new aerodynamic revisions.

Although Theissen didn't disclose a definite timeframe for the double diffuser development, it's assumable BMW will debut the feature in Monaco.

The Barcelona-spec aero package has long been in development. Therefore a double diffuser introduced at short notice wouldn't have brought us any benefit. There is no time limit set for when we will introduce the double diffuser in our car,” said Theissen in a preview for the Spanish race in Catalonia.

We will have an substantial update in Barcelona, from the front to the rear wing, affecting also the sidepods, there will be improvements in every detail,” he added.

The German official also revealed his team is yet to decide whether they'll take on a race-to-race development programme on the F1.09, depending on the results in the first couple of races.

The main reason we turned down the chance of updates during the first races was the testing restriction. The other reason was the interference with the aero package on the car. This approach looks to be wrong at the moment, but let's wait and see after a couple more races. Our first target for an update was always Barcelona and this will happen,” added the BMW official.
