F1's New Centreline Downwash Generating (CDG) Wing

So some designs are out for F1’s new Centreline Downwash Generating (CDG) Wing ...

All told, they’re wicked. What do they do, you ask? Here’s an explanation from the FIA:

The two-part wing, a result of aero research done by the sport's governing body in conjunction with technical partner AMD, is designed to promote overtaking by lessening airflow disruption immediately behind the car. Following cars would be able to get much closer before losing front downforce, hence making passing easier. The FIA hopes to introduce the wing in either 2007 or 2008, in conjunction with a return to wider, slick tyres.

The whole thing is to lessen the cars’ aero traction and get more mechanical traction (i.e. tires/tyres, suspension, etc.). The pic below shows the difference in turbulence coming off the car. The top is with the current wing, and the bottom is with the CDG....Tuff...
