Hummer is a brand of off-road vehicles sold by General Motors (GM). The original H1 was based on the military High Mobility Multipurpose Wheeled Vehicle (HMMWV, or Humvee). However, the Hummer H2 and the Hummer H3 were based on other, smaller civilian-market vehicles.

History

Hummers were originally built by AM General Corporation, which was formerly AMC Jeep's General Products division, in its Mishawaka, Indiana assembly plant. They were created under a contract for the United States armed forces. The first model, the Hum-Vee, was built in a variety of military-based equipment and versions. These included troop carriers, gun turrets and radar. The U.S. military, on receiving their quota, have adapted some of the vehicles, including modifications to facilitate a directional microwave crowd control beam (Active Denial System).

AM General had planned to sell a civilian version of the Hum-Vee as far back as the late 1980s. In 1990, two matching white Hum-Vees were driven from London to Beijing over the rough roads of central Soviet Union. The Hummers made the trip with ease, for they were built to drive on off-road terrain. The highlights of this journey were broadcast in the United States on ESPN. This publicity would pale in comparison to the attention that the HMMWV received for its service in Operation: Desert Storm the following year. Also, a privately-owned Hum-Vee was modified into the first Snow-Vee, including the addition of caterpillar tracks, a new rear compartment and a new engine. This vehicle was designed for use in and just below the Arctic Circle, and the Antarctic.

In 1992, AM General began selling a civilian version of the M998 High Mobility Multipurpose Wheeled Vehicle (HMMWV or Hum-Vee) vehicle to the public under the brand name "Hummer", called the Hummer H1.

In 1998, AM General sold the brand name to General Motors, but continued to manufacture the vehicles. GM is responsible for the marketing and distribution of all Hummers produced by AM General. In the next few years, GM introduced two new homegrown models, the H2 and H3, and renamed the original vehicle H1. AM General continued to build the H1 until it was discontinued in 2006, and is contracted by GM to produce the H2. The H3 is built in Shreveport, LA alongside the Chevrolet Colorado and GMC Canyon pickups, with which it shares the GMT-355 platform (custom modified and designated GMT-345).

The H2 is also assembled in Kaliningrad, Russia, by Avtotor, starting in June 2004. The plant produces a few hundred vehicles annually, and its output is limited to local consumption (five dealers in Russia initially).

On Tuesday 3 June 2008, one day prior to GM's annual shareholder meeting, Rick Wagoner, GM's CEO at that time, said the brand is being reviewed, and has the possibility of either being sold, having the production line completely redesigned, or being discontinued. This is due to the decreasing demand for large SUVs as a result of higher oil prices. Almost immediately after the announcement, a pair of Indian automakers, including Mahindra & Mahindra, expressed interest in purchasing all or part of Hummer.
