Ferrari F2007 - rear diffuser development 08 October 2007

The rear diffuser is being constantly developed on all the cars, but due to their positioning and complexity, changes are often difficult to spot. One you could see in China was to the outer side section on the Ferrari. Specifically, the outermost fence (arrow) close to the wheel is sloped rather than vertical, so as to create a sort of trapezoidal section to the channel (yellow highlight). This improves airflow extraction from beneath the car, hence increasing downforce.
