I Agree, though I am not trying to get rich off this deal. After the body is optimized, the chassis will be rebuilt in composite. There is still a Lot of Old Style pans around under unfinished or dead buggy's around here, though most would need to be lengthened.

With rear skirts and MOONs on the front wheels you should be very close,just as depicted.
The Beetle develops 57-lbs front lift at 62 mph.If your nose can dip as low as the bottom of the chassis,you ought to be able to kill that.
An Air Force roommate had a 57-hp Beetle and got 28-mpg.Dropping to Cd 0.20 with no change in frontal area would boost it to 36.3 mpg at 55-mph.

Inrekor panels are very strong and lightweight for chassis build.
You can laminate your own panels. The foam cores are polyethylene foam boards, made in China.

Inrekor unveils flat-pack production process | In-depth | The Engineer
Quote:
The composite Inrekor two-dimensional panels are constructed through a process of lamination. In the process, a core of ARPRO expanded polypropylene plastic foam manufactured by JSP is coated with adhesive then bonded between two thin sheets of aluminium, after which the adhesive between the two faces is cured.Once the two-dimensional panels have been manufactured, they are bonded together to form a three-dimensional chassis.

Inrekor identified the ARPRO material as suitable for use in its composite panel because of its cost and the ease by which it can be moulded, as well as its energy absorption and insulation properties - all characteristics that make the finished panels a suitable alternative to aluminium honeycomb panels while not incurring any of the expensive associated CNC machining costs.

Nice, how much? Put a Beetle body on it, run the Baja 1000, lets see how it holds up.

Crash tests have proven it among the strongest chassis.
All it takes is waterjet cutting the aluminum and polypropylene sheets, then bonding the sheets together. It's not that expensive.

This is—as they say—relevant to my interests. I visited www.inrekor.com but didn't find this drawing. Where is it from?

The projects they show go way beyond the refinement of that design.


Can non-flat parts be cut and folded like this, or must they be maufactured in 3D?

I found the drawing at this VW forum but it is in French language.
It is the chassis for the 356 Porsche roadster.
