Kach, I'd love to see the pics !
Supposedly, the car had an absolutely phenomenal Cd of .13* !
Have any of you found more info on this cars drag ? I'd love to see a modern day test, but have not come across one yet.
With Aerohead planning a trip to the wind tunnel, perhaps I can build a 1/4 scale model of the car to confirm that Cd .
PM if you like the idea Phil !

*To give some of the new readers here an idea of just how good that a .13 drag coefficient is, consider that this streamliner 'car' has a Cd of .147 ...so pretty close to .15.


The Panhard is listed at .13, with some sources giving a Cd of .12 !

Personally, I like this one the best:



And the bus would make a nice motor home.

It looks streetable. I like the cutout for tire clearance on the fender skirt, but it lacks the spat-like contour of the race car. The only other thing is the way the hood cut-line dies into the front wheelwell.

It's gonna have to be at least 1/3rd-scale to get a critical Reynolds number and correct coefficient.

I've got 42" across the roof. At half scale and 3.79 fineness ratio, that would be an 11ft model of a 22ft vehicle, with possibility of a 10% truncation. So that's possible.

Is there any reason to go 1/2 scale instead of 1/3rd?

Just saw this one and thought of this thread... the Maybach Exelero.

A one-off designed for high speed tire tests, later sold to a rapper who replaced those lovely aero wheels with some blingy crap.

Jcb dieselmax

I looked at my data for the JCB streamliner,and it shows up to Cd 0.17 measured for that car.

Slow to load website, well worth the wait.

Don't forget to use your scroll wheel on the very first (top view) image.

I didn't see anything on the coefficient of drag, but I'm guessing it's pretty clean.

The running boards open with the doors.

Porsche are going with an 800v system. Where will they find the fast charging stations. CHAdeMO for instance tops out at 500v.

Looks like Tesla beat them by a few years. But still interesting.
