Low-Drag Trucks: Aerodynamic Improvements & Flow Control System Boost Fuel Efficiency

Interesting, I wonder if the wing plans could be modified for the van and suv owners.

Wow, good find...

I'm surprised that more long haul fleet trucking companies don't get involved in making their trucks more fuel efficient. I know that some trucking companies have time limits on how long their trucks can idle. Making life for the driver a real pain..

For more detailed experimentation, measurement, and theorization about those ideas, see the PDF linked in this post:

This reminds me of an earlier thread. https://www.gassavers.org/showthread.php?t=1195

Nice, that's almost exactly what I want to do to the back of Marvin. I'll be using quartered pool noodles. The airfoil I will have a bit further underneath as part of a fairing for the rear live axle.
