Any updates? I'm looking to try and do some work to our beetle.

In some other thread ChazInMT pointed us back to 'Page with lots of Vortex discussion', where I found:

Here, I drew a picture. this is what Phil calls "attached vorticity"

I just want to say to Sven7, I loved the Stan Mott reference. An example? There're so many to choose from;
the Bugotti

When thinking about the back of the Beetle I was thinking that you might consider the differences between:
*Beetle
*AUDI TT
*Porsche 911
*Porsche 911 GT1 (1996)
When extreme performance is critical the solution is partly found in fineness ratio.
Compare the New Beetle,at L/H=2.56
the Porsche 911 GT1,at L/H=3.991
---------------------------------------------------------------------------
If the entire back of the Beetle were filled in up to the 'Template',you'd have the potential for Cd 0.314.
At say the old double-nickel speed limit,if you were getting 30 mpg,you'd be looking at 32.6 at factory length.

Rather then adding a boat tail, chop the roof / reshape the hatch to become the boat tail. My beetle roof is ridiculously high, a easy 12" above my head, i know a basket ball player could sit in it, with his knee's up by his ears, but his head would have plenty of room. By cutting you would be reducing and reshaping the mass.

Something like the old karmann ghia's only more matched more to the template.

Ponder the fineness ratio of the Woodruff Special.

It's a hoot to watch him get in. He crawls in head-first, rolls over and pulls his leg in.

Have you seen a decent chop on a New Beetle? The shape seems so rigid and symmetrical, I'm not sure how to pull it off. The factory lower the roof in a few concepts, then in production. They really changed the contour.

One of my favorite cars is the GTI 650 W12:

It has sort of an internal boat tail. Maybe you could do something with the side windows and backlight and leave the metal alone

I did see one chopped n beetle that did not look too rigid, i'll have to find the picture again. It was a dark blue beetle in someones driveway i believe.
I was thinking on the roof and it would be easiest to leave the windshield alone, start the boat tail slope from that point.
After looking at my car it looks like if you cut the roof and tilted it to the desired slope and reattached it, the car would retain its bubble shape.

The highest point on the roof is about in the middle of it, just cutting the bubble shape off it would reduce the height by 4-5 inches.

The 2012 bug has been chopped, in design.

still need to know what to do to my '01 to beat the air some more and squeeze a little more mpg out. also, how would y'all go about attaching smooth wheel covers improvised from non-wheel cover pizza plates

There are no holes. I guess i could draw it out and divide it though.
