About this model
The Hummer H2 is a full-size off-road SUV that was marketed by Hummer and built in the AM General facility under contract from General Motors from 2002 until 2009. It is based on a modified GMT820 GM three-quarter-ton pickup truck in the front and a half-ton 1500 frame in the rear. A four-door pickup truck version with a midgate that opens the vehicle's interior to the external cargo bed was introduced for the 2005 model year as the H2 SUT.
