Question about GM "Skateboard" chassis concept

Question about GM "Skateboard" chassis concept

Question about GM "Skateboard" chassis concept

(OP)
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?

RE: Question about GM "Skateboard" chassis concept

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 www.bcpictures.com/pdf/download.php?name=gm-fleet.pdf

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