The Hummer H1 is a civilian off-road vehicle based on the M998 Humvee, which was created by AM General. The vehicle was produced from 1992 through 2006, and was the first of what became the Hummer line. It was initially known only as the "Hummer"; however, in 1999 in a joint venture between General Motors and AM General, GM began marketing the Hummer H2, which was built on a heavily modified GMC 2500HD chassis. It was at this point that the original Hummer was given the H1 designation. For collectors, the most desirable model is the H1 Alpha, produced in the final model year of 2006. It had the most powerful engine and the best fuel mileage of the H1 vehicles. Overall, the H1 was a very limited production vehicle.
"Originally designed strictly for military use the four-wheel-drive utility vehicle was released to the civilian market due to popular demand. Boasting 16 inches (40 cm) of ground clearance as well as super-aggressive approach and departure angles, the Humvee could clamber over a 22-inch (56 cm) high obstacle, handle a 60 percent grade and wade through up to 30 inches (76 cm) of water.”
The Hummer H1 has three common variants: a convertible-like soft top, a four-door hard top Sport Utility Truck and an Alpha Wagon body version. Other less known variants include a two-door pickup truck, most commonly seen in the military sporting Anti-Air turrets and other launchers, or used as troop and cargo transports, and a four-door slantback, which shares the same body style of the Humvee employed by the U.S. Military. 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.
The "Alpha" was an extensively re-engineered H1 that was equipped with GMs Duramax Diesel and 5-speed Allison transmission. The previous version of the H1 with the 6.5L "Optimizer" turbo-diesel engine suffered from sluggish sales; lack of power was one of the reasons for customer resistance. In 2002, AM General CEO Jim Armour took the idea of repowering the H1 to Bob Lutz and the GM Luxury Vehicle committee. GM soon approved the use of their Duramax/Allison powertrain for the H1. This would support the continuation of the H1 as the grandparent of the Hummer portfolio; it would also allow AM General to give the truck a much needed dose of updating in terms of power, torque, refinement and the ability to meet 2004 heavy duty EPA emissions requirements.
The update program commenced in late 2002 with production launch slated to be fall of 2004. The
