That graphic did come from Scout at the presentation though, so I'm definitely analyzing it.
The front suspension appears to be a standard short/long arm double wishbone with a strut. Pretty common, offers decent handling and road feel. The rear suspension appears to be a standard 4 link and I'll assume a panhard bar or something for lateral axle support that I can't see, but I don't see any shocks or struts out back, possibly because those are also part of the body, so not shown on the chassis. I'd expect a coil spring and shock with that setup though. Again, common layout, functional, generally easy to work on and maintain.
The rear harvester engine is decently flat, but still looks to hang a little low in the rear, much like an auxiliary gas tank on a Jeep, so it'll likely have a rear skid plate protecting it.
The rear axle has the drive unit integrated as I expected, but that's going to make for a lot of unsprung weight to control with the springs and shocks. This will typically be felt on rough payment or over bumps, expansion joints, etc. In a turn, this will often make the rear end jump around a little bit as the suspension tries to control the weight of the body, but being slow-acting since it weighs so much itself.
The Harvester definitely sits back there a ways, but I'm assuming they're beefing up the frame as needed. With a spare on the back, the weight distribution will be interesting to see. With all electronic nannies turned off, this thing might be prone to snap oversteer. Hopefully they don't bake in too much understeer to counter this possible issue. If 911's can manage this with electronics, so can Scout.
