H1 H2 H3
Hummers were originally built by AM General Corporation, formerly the military and government vehicle division of American Motors, in its South Bend, Indiana assembly plant. AM General had planned to sell a civilian version of the Hummer as far back as the late 1980s. In 1990, two matching white Hummers 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.
2006 Hummer lineup: H3, H1, and H2 As of 2006, Hummer has gone international with selected importers and distributors in Europe and other markets.
Since October 10, 2006, GM has been producing the Hummer H3 at its Port Elizabeth plant in South Africa for international markets. Hummers at the Port Elizabeth plant will be built both for local South African consumption and for export to Australia (for the 2008 model year), Europe, the Middle East, and Japan. As of October 2006, Hummer vehicles are marketed by about 300 dealers in 34 countries. 173 of those are in the U.S.
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 May 12, 2006, GM announced it would cease production of the original H1 Hummer.
GM CEO Rick Wagoner has said the Hummer brand of trucks will run on Biodiesel
Hummer H1 vs. HMMWV
The Hummer H1 is basically a HMMWV built for civilian use; it, obviously, has no armor or weapons fittings. However, the drive-train, frame, body, suspension, etc., are exactly the same. The H1 differs from the HMMWV in having a civilian interior, including trim, comfortable seats, stereo, and air conditioning as standard options. As a result of its commercial use, features introduced in the civilian Hummer have been incorporated into improved military versions. The H1's electrical system is 12 volts, with the two batteries wired in parallel. The HMMWV runs off a 24V system, where the two batteries are run in series to generate 24 volts.
