Hummer - H1
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.
Selling the H1s to friendly foreign governments and US organizations with emissions exemptions will allow AM General to not be subjected to the new 2007 Tier 2 Bin 5 emission rules and regulations. AM General has sufficient fleet orders to produce 600-800 units per year right now. The fleet H1s will end up using the standard 6.5 L Turbo Diesel that has been commonplace in GM and commercial applications.
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. The convertible/soft top and the station wagon versions were the last ones available in the mass market. The two door and four door pickup versions are only available in fleet livery.
