Apparently, it lowers the Insights Cd of 0.26 to 0.12 .

Note: they've also added front wheel covers in the picture.

It could very well be PS .
There's also a line in the floor underneath the middle wheel.
There's no such line on the insight-only picture, though the light reflection spots are all in the same position.
There's a faint line in the floor, just aft of the mirror that also returns in both pictures.

euromodder,sorry,that image is not real.
It's a cut and paste job I did from some materials I got in Japan from HONDA.You'll find it in the Phil Knox's Aero. Photos Album.
Some people have been posting it as something that exists.It IS the premise for my Full-Boat-Tail-Trailer -For-T-100-Pickup.

It would be pretty easy and cheap to use zote foam to fill in the gaps if you thought it necessary. I am surprised that no one here has worked with it.

Here is my biggest creation with it.

It is made from 1/2" thick foam with a minimal plastic/carbon/balsa frame. The chassis is a Catrike, Pocket.

They used flush but flexible panels to bridge the gap between towing vehicle and trailer.

Interesting stuff, as it seems to be very light.

Here's a description of how to use the stuff (when building a velomobile)

Builder John Tetz is even using thicker Zotefoam shaped as "angle iron" for internal bracing.

And a video of the end product :

John T is a friend of mine. I built my yellow fairing in an evening. I was going to make the bottom like his but didn't have enough material so I went with a ground effects type of design. It worked pretty well but it acted like a vacuum cleaner on the dust off the road. My lungs still protesting some today.

Zote wouldn't work well on a front fairing in an automotive application but it could be useful on trailing areas. It can be heat molded into 3D shapes.
