My motorhead's guess, no differential but instead a spool in the rear and still turning while adding power caused differing loads in the rear tires, causing a terrible wobble as the tires fought each other (and the suspension), ending by ripping out the rear suspension.
EDIT: That's why I use a Detroit locker in my Jeep, it's a spool when you add power, and a differential when you let off power.

I have been looking forward to this for a long time. Haters sit back. Just shhhhhhhhhh. Hush now. We know. We don't care. We rikey.

This is an old man '90s moment, i watched Jurassic Park around a dozen times in theaters. We used to go to the cheap theaters 5 years after release and JP would still be playing every weekend. This certainly won't be the same phenomenon but it sorta feels like it could be good.

A nice "could be good" is enough for me at the moment.

Btw, I know and play video games with the guy who drives the JP Jeep around Orange County, CA and a coworker of mine like still wears Jurassic Park shirts he's had since he was 12. So we have ourselves a little fan club.

This is one extremely well made machine. I cannot even believe how extremely well this held together, even after the crash (it was practically still in one piece). I find this carbon-fiber/single piece engineering breed of helicopter fascinating. It is far better in a number of fields--and then on top of EVERYTHING to see it go through this absolutely catastrophic situation and remain in one piece (as they said, many helicopters would start breaking apart mid-air due to the absolute savagery of the forces involved and at play here; yet this thing holds together the whole time, even though it is a test design and not even an "improved" or possibly it's "final" design).

I really think that this type of design and make will eventually start to make it's way through the industry. It is just too obvious that the bonuses out-way the negatives to me--then add in the fact that while still in it's testing phase they successfully handled a "worst case" scenario breakdown for a helicopter and then crashed it, then once again showing that the helicopter was VERY good at sending all the forces across the design and holding together (showing that it did a good job during TWO events really)... I really don't know how you couldn't be a bit hyped for this type of design moving forward if you were a helicopter engineer, pilot, mechanic, and especially the manufacturers.

To me, my first thought was, this could end up being the "jeep" of helicopters...

Where's a mid 90s Jeep Grand Cherokee when you need one?

Jeep Grand Cherokee Moose Test - The Full Story has been added as a related post - related requested by oritteropo.

It's a standard car handling test, simulating avoiding a Moose (a common problem in rural Sweden, or so I'm led to believe)

I first heard of it from the Mercedes Benz A class Moose test failure referenced at the end of the vid above... in that case, many of the journalists rang in their stories (Lada beats Mercedes Benz) first before checking whether the driver was OK!

Actually, before 1997 it was known as “Undanmanöverprov”, Avoidance Maneuver Test, the name "Moose Test" was coined in the aftermath of the Mercedes Benz failure.

Dude, swamp racing jeeps need special equipment.

Howdy... the rear triple axel unit is often referred to as a "jeep". It is steerable (have a look at the two opposed hydraulic cylinders above the jeep frame and below the load... you can see the sun glint off the left cylinder at 0:07). The control lines for the jeep are running forward to the cab through the lines which are bundled just ahead of the 3 boomers that are holding down the load, and riding up on top of the beam. In the final 3 or 4 seconds of the video, you can see the black sheathed control lines bouncing up and down, still attached back to the jeep which is out of frame on the RHS. The mistake here is that the jeep wasn't controlled properly during the turn (it's one or sometimes two buttons in the cab, often attached to or near the gear shift for single finger operation); during the turn the jeep is turned to make a wide turn and stay in lane, and once the turn is made, the jeep should be brought back to a 0° (straight running) position, but it looks like it was left a few degrees right and thus hit the concrete guardrail. 10-4.
