It was much faster than sitting through a video. Is this what were talking about? How does it relate to the Bowlus Road Chief?

I have my own theory about an aero trailer.



Citation needed. Is it Fuller's vector equilibrium?

Your trailer is similar.Theirs is a 16-footer.Cimarron told me that all their trailers are custom built,per customer specs,and I'd have to get the VIN for them to tell me the actual dimensions.So I had to attempt scaling off the computer screen.I'm in the ball park.Frontal area is around 62-sq-ft.A little over 93-inches tall.95-inches wide at the exposed wheels/fenders.It's a semi-V-nose,which actually hurts it aerodynamically.A Featherlite,more-blunted-nose,car-hauler would pull easier.Their fenders aren't as offensive either,and they offer a softer radii,especially up top.ShowStar has no belly pan.From the energy balance,the Tesla/Cimarron combination is approx. Cd o.4526 (higher than Jason allows),and a drag factor of CdA 28.06 sq-ft,also higher than SAE suggests.At 9860-pounds all-up weight.
The combination can be lowered to Cd 0.2035,and CdA 16.8 sq-ft,with 66.5 mpg-e,and 202.9-miles range in California.

The Bowlus-Teller Road Chief has been reintroduced.'Naked',in a wind tunnel,it has the drag of Dymaxion (0.25) and approx. 49.3-sq-ft frontal area.Streamlined,with the Tesla X,the combination is approx. Cd 0.153,at CdA 7.556 sq-ft,103.6 mpg-e @55-mph,and 316.3-miles range,on the available 92.24 kWh .

As to the architecture,all I can say is that it is described as a (a cubic-octet) closed cell foam.It's the strongest structural element known.
