Given the massive weight of the HEV im curious how it will fair against a mud pit or some sand dunes. Im sure the tires would need to have some more aggressive tread but curious if you think the weight has potential to affect the tenancy of getting stuck or dug in. 4 wheel steering brings an entirely new element to the field but the weight still does concern me a bit. Hopefully GM is doing a bit of testing in these areas as well or at least allowing for equipping a winch at some point in the future even if after market.

Under the right conditions more weight is bad, under other conditions more weight is good. The contact patch of the HummerEv tires is large enough I do not think you will see a huge difference between say a TRX, and the Hummer EV. If I was going out in soft mud, I might install wider/taller tires. One thing about the Hummer EV is it should be easier to recover from deep mud than say a TRX, due to the almost flat bottom, where as the TRX would have to pull the axle our of deeper mud than the belly. On the TRX all the projection from the belly pan become plows when you try to pull it out, and give more surface area of resistance. The belly pan of the Hummer was designed such that it should not get hydraulic locked into the mud, but time will tell on that.
