The "Kamm-back" (K-form)

[ecomodded]

This is the thread I was looking for , I am thinking not all cars are born with a Kammback , but most can be hacked into submission

I made a plastic model of one of those Trans Am wagons when I was a kid.

I was thinking hard on hacking the Beetle into a Kammback but the costs of materials as well as "wrecking" the Beetle's resale etc. etc. I decided to go with a bolt on design.


So new Plan is a bolt on Kammback with the frame made from aluminum or a shaped hand carved wood ,foam filled and fiberglassed skinned. I have left over fiberglass mat and Roving ,around a 100Ft x 4ft & tools. I am pretty confident I can give the Canopy/ Kammback a factory like finish, with the help of my belt sander and a gallon of gel coat to finish it with.

I am thinking Now , it will be a shorty but a goody , no longer then the cars current bumper , but shaped in Mr kammbacks design. I want to find the lowest cd modern hatch back design and copy it / emulate it.

I really like the Audi A2 's design , its makes for a simple low cd car , Any tips or recommendation of modern Kammback cars I could use for inspration would be appreciated !

I am going to do a cardboard mock up on the car to look for a natural fit of the template / Kammback on the beetle, My car has tappered sides so I think it will be well received on the Beetle.

Freebeard , car #1 with the roof racks , looks close to what I'm thinking Now !

Neat rendering !

Geneva Auto Show: Edag Biwak recalls (some)Thing - Autoblog

How does the vertical height of their back door compare to the vertical height of the stock hatch?

It's a more complex build with the fenders and rear bumper included; but you should be able to reproduce the top contour with an additional seam. Consider a clip that reaches forward of the hatch opening sufficient to get ahead of where it starts to fall off.

Edit: some other stuff EDAG does is pretty far out there, e.g., Genesis; but here is the relevant contour on their Light Car Concept.


Black under pinpoint lights doesn't photograph well. The pictures load better down in the comments. It's made out of Basalt fiber!

So far in the design stage , I am thinking I could attach it like a canopy in place of the rear Hatch , but still use it as a hatch back , with the same hinges, So it opens as normal Only with a lightweight Kammback.


I Never realized it was a concept car , It looked like a Photoshop rendition.

The Hatch top is not far off from the canopy's top on the concept Beetle , I think your right though , add a little roof fill to blend it at the right height, transition. It could be siliconed in place and left on the roof, The hinges swing the hatch out and up when it opens, so it clears the roof now.

My Rear fender flairs could use wheel skirts and some blending in toward the front doors.
If I used some deeper back spaced rear wheels it will move the rear tires inward a inch or two or what ever i can get away with , possible allowing me to trim the fender flair into a more aerodynamic conducive shape.

I don't mind cutting my fenders so much , they are part of the plastic bumper covers that I can replace , with better customs ones , front and rear for about $1000 which would restore the damage and upgrade the cars original value.
