The Diffuser Controversy - continued

This latest suggestion from Sam Michal, technical director at Williams, suggests that increasing diffuser downforce aids the following car's ability to overtake. Thi contradicts Briatore's suggestion that the opposite is true. Confusing...

"It is clear in the regulations what you can do," he said. "That is what the FIA thinks, that is what the stewards think. The OWG [Overtaking Working Group] finding was that producing more diffuser downforce resulted in an increase in downwash for the following car and improved overtaking capability."

"So from that point of view, our diffuser is helping overtaking and the others are not. That study was done by Renault, Ferrari, McLaren and BMW Sauber. So by their own studies they said we should increase diffuser downforce, and that is what we have done."
