What in the world?! Stumbled upon it while surfing a popular car site recently...
It's a chainlinked (as stated in the video title) 4x4 exhibition of nothing I've ever seen before! The wheels not only work independently of each other, but go a step further to exceed the articulation limits of a otherwise hardcore off-road vehicle. Controlling all of that movement is a Rube Goldberg gear network: 5.38 gears and centrally-mounted ARB air locker, chain gears at the swingarm pivots, and chains inside the swingarms to work Hummer hubs at each wheel.
But just watch the video either way...it'd be sure to blow your mind!
