Judging by this prototype caught under test, it looks like the HUMMER H2 SUT is on the verge of a growth spurt. This H2 SUT tester — parading around in what appears to be a faux army paint scheme (complete with star) — has clearly been lengthened behind the rear doors. It appears that a good 12 inches has been added both fore and aft of the rear wheel, resulting in a significant increase in hauling capacity over the compromised bed of the current H2 SUT.
We would guess that this new, longer H2 is making use of the stretched GMT 900 platform used on the Suburban instead of the H2's normal Tahoe-based package. The strategy was probably deemed necessary to properly differentiate the H2 SUT from the upcoming H3 SUT, which sports a similarly stretched bed when compared to its SUV counterpart. If the H2 SUT has ever made any sense, its relevance would be severely challenged if the smaller H3 pickup actually trumped the H2 in functionality. The General is now in the process of rectifying this shortcoming. One now wonders if this lengthened treatment will also be applied to the H2 SUV.
