Is above for all vehicles or just cars/light trucks?

The airdam on the Corolla is integral with the front fascia.It even has a vestigial splitter.
It's true that it isn't as 'deep' as the actual low point of the underbody,but it would be just a matter of giving the belly some gentle upsweep,as Tesla (current low drag champion) does,to terminate at the bottom of the airdam.Look under an S model next time you're around one.
Hucho's 'ideal' nose dates to 1976.
It's predecessor can be found with R.G.S.White's search at MIRA in 1969.
White's predecessor can be found with Fachsenfeld/Kamm in 1935,which is linked to Jaray in 1922,which is linked to Eiffel,1889.This is very old technology!
It can be used in all light and heavy vehicles below 250-mph.The atmosphere doesn't discriminate.
The dollar figure is just for the highway portion of 261,000,000 autos and light trucks,circa 2015,@ $2.249/gallon,13,476 miles/year/vehicle,and 21.4 mpg Combined; using 45% of total miles as EPA HWY.
