Re: pic: High Traction Drivetrain Concept
This isn't exactly new; this wasn't an uncommon layout in 2010 and later when 8WDs started gaining traction.
In short these have similar results to a 2 traction 4 omni setup vs a 6WD. Most of the problems "solved" by this drive are minuscule / imaginary. Rock shouldnt be big enough to be the difference maker in a bumper to bumper pushing match; we are literally talking about a 1/16th inch difference in bumper height here. The omni wheels lower resistance to being spun more than the 8WD all traction designs do given the same wheel layout. Omnis also don't match the lateral traction of Colsons or traded traction wheels, so you're giving up a little there.
Basically, you need a really good reason to not have a drop center for this to be the right call. Given that an unequal spaced 8WD already doesn't do much rocking at all, it's hard to find a niche for this drive.
