BMW introduce their own DDD

BMW Sauber have taken a long time to design and manufacture a double decker diffuser to replace the more conventional one that followed 'the spirit of the rules'. The new version immediately proved effective as Robert Kubica was there within the points, while in Bahrain they were no where near the midfield.

The new diffuser resembles much that of Brawn with an empty keel structure in the middle and an early exit above it for additional downforce. It also pick up an idea of Toyota by creating a small extension to the diffuser under the rear crash structure - with the safety light, the only area where the diffuser is allowed to extend further behind the rear wheels.
