Although this was written with some intervention by marketing people its a semi-summary of some work I was contracted to do for a wing design using CFD. I hope it helps.http://www.amb-aero.com/files/APR004_public.pdf
It was a bit different than the usual stuff I would do for motorsport, fun project actually.
About the profiles, I dont think anything out there really varies all that much from SOMETHING that was tested by NACA. People change the nose profile, camber and peak camber points but thats really about it. I dont even see the point in giving them so many names I can describe a 2d profile with five or six data points 99% of the time.
The recent innovations seem to all be playing with tip vortex formation, canted spans as well as all the trick little stall/anti stall devices you saw in F1. In SuperGT, some years back the rules changed to a single element, everyone was trying to get a bit more AOA before stall by forming vortices on the low pressure side it's standard fare now.
For F1, I suspect its heavily weighted toward the diffuser function ... the total car performance. My $.02.
