It is a long car - length has no effect on Cd, it just adds more surface to have drag on -and I bet the underside is one big aerodynamic mess.
The wing just enlarges the wake.

Cd 0.4? They must have been doing something right too then!
*(airdam)It has one that was optimized in the wind tunnel.
*rear window


*wing,it's a 200+ mph race car.It needed the wing

Nobody liked the retro-tricycle? It pushes a lot of my buttons. It can be yours for $16.95. How about the Freezemobile from 1997's Batman & Robin?



It's got four wheels but it leaves me a little cold. OTOH I discovered that

http://www.imcdb.org/vehicles_make-Made+For+Movie.html

has every made-for-movies car, evah. Including the Herkimer Battle Jitney. It's got better fenders.

.201 Cd - that is one count higher than an EV-1.

I imagine a lot of air is smacking into those back tires. I would guess a nice rocker panel extension could bring that Cd down to under .19 !

That's a heck of an improvement from 0.4, 0.37, and so forth we have seen on the street versions tested.

I did not expect the aero-template to be so close, guess I had been looking at the street versions without the modified back window.

I didn't see a link for that SAE paper (other than the cover I posted), can that viewed online for free?

Nice ecommoder find Freebeard, page 3 link leads to a Google book and tells us the Daytona had a real front wheel vent and the Superbird didn't.

I'm under the impression that this guy is mostly in it for the artistic value, but:

What feels really strange is when Google Images shows me a picture I drew myself.

I'm working (hah!) my way through the imdb made-for-movies cars. I'm on page 12 of 33.

I suspect that you're correct,but the SCTA and USFRA rule books won't allow the mods for the class they're competing in.
Airdams, spoilers,and fences are considered 'safety' equipment.

I'm not sure about free online papers.
A member generously shared and slow-mailed me a copy of it years ago.

Here is an interesting picture. A brick and a slippery fish.
( 1963 Panhard )

Also, here is a picture I had not seen here of the original Panhard CD62 Prototype

And the LeMan racer


The Panhard has been posted here before, but the above picture is the most beautiful one I have yet to see of the car.

I may have taken some pictures of one at the Orphan Auto Show in Ypsilanti, Michigan last month. I'll post them if I can find them. Pictures of the Panhard are always welcomed in my opinion.

There were two at the Rolling Sculpture Auto Show in downtown Ann Arbor this summer. I'll try to see if I clicked a few photos there as well.
