The Hummer H1 was a civilian vehicle based on the M998 High Mobility Multipurpose Wheeled Vehicle (HMMWV), popularly known as the Humvee, which was created by AM General. The vehicle was produced from 1992 through 2006.Originally released in the civilian market in 1992, the Hummer H1 owed its birth to the popularity of photos from Operation Desert Storm and the enthusiastic campaign from actor Arnold Schwarzenegger, who personally owns several variants of Hummer vehicles. GM announced that 2006 would be the last model year for the Hummer H1, with production winding down in June 2006 due to a new emission law for Diesel engine vehicles which takes effect in 2007.Due to the requirement to meet EPA Tier 2 Bin 5 emissions standards, the cost involving recertification for a low volume civilian variant vehicle was not able to be justified. AM General currently has orders for an excess of 50,000 new HMMWVs to be produced between 2006-2009 for the United States Military. AM General also will continue to produce the H1, just not the Alpha. These vehicles will be sold through fleet sales.
The Hummer H1 has three common variants: a convertible-like soft top, a four-door hard top pickup truck and a Wagon body version. Other less known variants include a two-door pickup truck and a four-door slantback. At this time, the convertible/soft top and the station wagon versions are the only ones available in the mass market. The two door and four door pickup versions are only available in fleet livery.
