...Jim... something... Hall, maybe? Had a car called a Chapa-- Chapa-- something... hmmmmmm 
P.S.
I've talked to a couple teams now that have talked about running something like the old Chaparral but get caught with the rule about "two engines". The Chaparral used a snow mobile engine to run those fans and it made something like 50hp and NEEDED every bit of it! Everyone should research as much as they can on Jim Hall and his Chaparrals, he was arguably the most outside the box thinker in motorsport history... automatic transmissions, vacuum-assisted traction, hub-mounted wing uprights, and the first application for Lexan, to name a few innovations...

"The CHeAPARRAL 2J-2 “sucker vette” story is about a group of engineers
who work for Procter & Gamble in Cincinnati, Ohio. This team challenged
themselves by putting to use many of the math, physics and other
scientific principles they've learned over their lifetimes to build a unique
car to compete in the national Grassroots Motorsports Challenge. Wild
ideas, sound engineering and resourcefulness led to a winning design and
later opened doors to meet a couple legends in the automotive world, Jim
Hall and Jay Leno (check out the "Leno and Hall" tab). As many race car
buffs will notice from our team name, our wildest idea was reapplying the
concept of active downforce, originally pioneered by Jim Hall and
Chaparral Racing in the 70’s. But we had to figure out how to adapt it to a
production car while only spending hundreds of dollars, and do it in a
couple of months!"

While that front wing hanging off the front of the car may be effective, it's not really practical under normal driving conditions for anything but a pure track car. I'm wondering how effective that same wing would be if it was integrated into the front bumper in some manner. It may have less downforce that way but it wouldn't be hanging out in front of the car blocking your vision either.
Oh nice shots! I'm sure the wing up front in clean air is "the best" but sometimes looks and practicality do count as well. Integrating that wing into the front bumper looks like it could be quite effective if done right.
Think about this - the air in the front of the car, even without a wing, is already going up and over the car. WITH the wing in the front bumper area - how much more can it force up and over the car. . . not alot. . .
RADO's idea is vastly superior to the ideas in the old Audis. Will work much better. . .
BUT - when dealing with front canards or wings - it will in almost all cases detract from the rear downforce. The turbulence created will wreak havoc on the rear wing's ability to function. You may gain more DF in the front, but it will take away from DF in the rear . . .
Fortunately in most racing gategories the rear is more open than in front in regards to modifications. So, the way I look at things, you MAXIMIZE downforce in the front, and use the allowances in the rear to balance it out and give you a neutral handling car. . . .
BIG splitters and canards in the front and balance them out with the wing/diffuser in the rear. . . .
