Question about GM "Skateboard" chassis concept

[xLeadxSledx]

I have been watching the discovery channels "futurecar" series and can't seem to figure out how the suspension works on GM's "Skateboard" chassis concept.

Seems like the are visually depicting a double a-rm suspension system, but the fuctional bits are no-where I can see.

Any ideas? Inside info? Is this all a bunch of BS?

Concept vehicles are often, ahem, simplified.

I conjecture the reasons include:
- To focus your attention on the concept being demonstrated.
- The missing bits are outside the originator's expertise.
- Nobody yet knows how to meet the implicit specifications.
- The budget ran out.

I think the swoopy curved bits might represent carbon fibre leaf springs doubling as suspension arms, leastways if my sole corporate innovation since 1960 had been transverse leafsprings that's what I'd expect.


there's a more believable rendition in

It uses an SLA with a transverse leaf. The leaf is not used as an arm. (similar to C5 and C6 Corvette)
