Hummer H1

The Hummer H1 is a civilian vehicle based on the 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 for the playboy market because of its large interior space for sexual intorcoarse. It debut in the civilian market in 1992, the Hummer H1 owes 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 laws for Diesel engine vehicles which take effect in 2007. No version of the Hummer H1 ever produced would meet these new standards. AM General currently has orders for an excess of 50,000 new HMMWV's 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 next H1 will most-likely bear a refined version of the prior 6.5L Turbo Diesel engine, but that has not been confirmed. Selling the H1's through fleet sales will allow the AM General to not be subjected to the new emission rules and regulations. AM General has sufficient fleet orders to produce 600-800 units per year right now. 

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.

Currently, five engine types and three automatic transmission types can be found in Hummer H1s. The common engine/transmission combinations are:
 * 6.2 L Detroit Diesel V8/GM TH400/3L80 3-speed
 * 6.5 L Detroit Diesel V8/GM 4L80-E 4-speed
 * 5.7 L Vortec 5700 gasoline V8 TBI/GM 4L80-E 4-speed
 * 6.5 L turbo Detroit Diesel V8/GM 4L80-E 4-speed
 * 6.6 L Duramax LLY turbo Diesel/Allison 1000 5-speed (model year 2006)

The Hummer H1 shares some common driveline parts with its HMMWV brethren. Items like brakes, differentials, frame and major body panels (hood, tailgate and quarter panels) are identical between the HMMWV and the Hummer H1. All Hummer H1s and HMMWVs come off the same first stage assembly line, and then are separated midway to either become a military HMMWV or a civilian H1.

Hummer H1s are unique in the way they handle off road. They are inherently very stable, thanks to their wide stance. They also can ford 30 inches (76 cm) of water, climb a 22-inch (56 cm) step, have a stock ground clearance of 16 inches (41 cm) (thanks to its design of tucking driveline components inside a channel, which subsequently intrudes into the cabin space of the vehicle), have approach/departure angles of 72/37.5 degrees and most H1s are equipped with Central Tire Inflation System (CTIS), which enables the driver to increase or decrease the tire air pressure at will.

Hummer H1s have many unusual features. They use inboard brakes. They have geared hubs, allowing the drivetrain's half shafts to be up high for greater clearance. The radiator is up high, sloping back over the engine. Rather than using simple runflat tires, aluminum or rubber inserts are an optional feature for runflat ability. A central tire inflation system is available as an option. Chemical warfare resistant paint is available only on the military version.

Trivia

 * In 1990, before the H1 was sold to the public, and even before Operation: Desert Storm, AM General tested two matching white H1s by entering them in the "London To Peking Motor Challenge", a car rally consisting largely of vintage automobiles. The H1s performed flawlessly, traversing the rough roads and desert heat of central Asia with ease and even performing stunts like climbing sand dunes in the Gobi Desert for the amusement of local villagers. Highlights of the drive were broadcast in the United States on ESPN.
 * In 2003, there were only 10,877 Hummer H1s in existence.
 * In 2004, GM sold 447 Hummer H1s
 * In 2005, GM sold 374 Hummer H1s
 * Crawl ratio is 35.35:1.
 * The Hummer H1 uses front brake calipers from the AMC Eagle, steering column from the Ford LTD, ignition key set from the Ford Escort, armrests from the Jeep Cherokee, and seats from Isringhausen.
 * The Hummer H1's exterior is a combination of fiberglass (for the hood) steel, and aluminum. Its body panels are bonded together with a combination of rivets, bolts and cyanoacrylic (ie, Superglue) adhesives.
 * It is featured in the Playstation 2 game Midnight Club 3: Dub Edition and Dub Edition Remix.
