Interesting amount of body movement under hard acceleration.

The driver gunned it coming out of GM's Milford Proving Ground.

That's a pretty decent squat for a truck like that. The suspension is working overtime there. Let's see if that carries over to the production model or if it gets adjusted.

GM released a video showing hard access to brake events and the body rolls a lot, not sure if that will be tightened up for production or not. I am not an expert in traction and weight transfer to understand that suspension setup. See this video at 3:40

Yeah that does seem like it's more body roll than it should be. But then again it's also a ridiculously heavy truck.

How much do you think the Hummer SUT weighs?
