It's rumoured that Williams and Renault both have a revolutionary rear wings in development, whihch won't be launched till Oz.
The "W" wing is all that is known...
So the CFD'ers, Aerodynamicists and other clever sods on here...what do you expect, what's within the rules?
I remember the V shaped lower rear wings used for while, could it be a development on this theme? Or could it be a W in shape when viewed from above??
Summations on a postcard please
