The 2009 HUMMER H2 is a full-size SUV based on the GM full-size pickup platform and drawing from the HUMMER H1 that was originally designed for military use. The H2 was the first new vehicle under the HUMMER brand since GM acquired exclusive ownership of the HUMMER brand. The H2 may be scaled down, but it offers all the capability expected from HUMMER. The H2 SUT was added for 2005. The OnStar advanced communication system is standard on the Hummer H2.

Note: Because the GVWR of the H2 is 8,600 lbs, the automaker is not required to release fuel economy ratings, and the EPA does not test the H2.
