[T3] Aerodynamic Drag

I've often wondered why the rear screen on my Squareback remains
surprisingly clear when my other cars get rain-coated so readily.  Obviously
the major difference is the air sucked in by the air-cooling, but is there
another reason?  Does a Notchback stay clean?

Here's a YouTube video that discusses a paper about aerodynamic drag on
fastbacks, notchbacks, and squarebacks. The body shapes are more modern than
on our cars, but it's still interesting that they used our names. 
Here's the link to the video:


And here's the link to the complete paper. I haven't waded thru this yet,
but I intend to.


There are some surprises here.
