The Hummer H1 is a four-wheel-drive utility vehicle based on the M998 Humvee, which was developed by AM General when it was a subsidiary of American Motors Corporation (AMC). Originally designed strictly for military use, the off-road vehicle was released to the civilian market.
The civilian version was produced from 1992 through 2006 and was the first of what became the Hummer line. AM General built both the H1 and the Humvee in its Mishawaka, Indiana, facility. GM stopped marketing the H1 in the 2006 model year, but AM General continued production of the military Humvee versions through 2018.
