Our next rig will have active aero shutters like the Chevy Cruze Eco. Right now, the inlet is too big for winter and too big too warm up fast when cold outside. But you are of course correct. Radiator airflow is directly proportional to fuel economy.
Now that bs is aside, man,
that is one cool fan! Any more pictures or description available?
That fan is a product of one of our major sponsors, Horton Cooling.

I can't say enough good things about them. Great folks to work with. Smart and savvy. Been in business over 60 years. They flew their engineers on their company BeechJet from Minnesota to my shop in Connecticut twice, to help me engineer it and set it up. I designed and fabbed all the aluminum tube and bracket frame-work you see in the pics.
By the way, you are looking at probably the only Class 8 rig in North America with a crankshaft-driven fan. Horton's computer-controlled Stratis viscous drive is sandwiched in between the two. And they built me a beautiful, billet, CNC piece that bolts to the crank and ties everything else together.
