The left side a) is quite similar to the ideal template we have been working with:



Though the apex is farther back. The Jaray concept bugs me - it seems to be 2D thinking trying to be 3D? The sharp corner at the intersection between the shapes would add drag, by definition, and it requires two distinct "expansions" of the air, which seems less than ideal.

I did a quick SketchUp model (intersection of two extrusions) of the a) drawing above, to see what it might look like. I moved the rear wheels back because the tail overhang is way too long to be practical.



I'm not sure how practical it would be. The wheel tack is very narrow and the height is pretty low. The wheels are about 25" in diameter, which is a 15" rim, and I scaled everything based on that. The length ends up at about 15'-8" and the maximum height is ~4'-1". (The standing figure is about 5'-6" tall.) The minimum ground clearance is ~7 1/2" - and the center to center wheel track is only 2'-9 1/2"; which is not a good thing. The front wheels need to be moved back and be wider apart.

He is obviously a very smart man. But I don't know why he puts such a square 1940-2012 type truck in his wonderful wind tunnel. Almost barn-door flat in front, Ill-fitting roof fairing, too small, too low, to far rearward. Non-aero mirrors. No side skirts. No rear of truck aero device. Everyone here knows such a vehicle would produce the tremendous tornadic vortices of smoke in the rear of the vehicle that we see in this image. What's the point?

Why not use this wonderful tool he has to improve the machine?

I would be glad to ship him our 2015 Concept Vehicle 3D Printed model to test, if I was sure it wouldn't be rubble after the 7500 mile round trip.

A long pointy front is not really helpful until you hit 250mph. Below that, a blunt slightly rounded front is just as good as anything.
