As said, a DeDion implemented with a space frame can be far lighter than a huge tube stressed entirely in bending.
Could also be done as a stressed skin torque box (essentially a monocoque structure), but it is far more difficult to package,
since the diff will be enclosed within it, and you must have openings for things like the driveshaft, axles, etc.
(ISTR that Jim Hall tried something like that on one of the later Chapparals)
Think of a Classical DeDion as two vertical links with hubs that carry the wheels, rigidly connected by a stiff beam.
Even if there is built in pre-set camber or toe, the rigid beam is responsible for all wheel location and control, just like a live axle.
But lets think a moment about what is really required, and what we might do differently to achieve the same goal:
1) Camber control; just like a live axle, each tire should be equal, if one side changes the other side does too by same amount.
2) Toe control; just like a live axle, each…
