The Hummer H1 is a four-wheel-drive utility 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. Originally designed strictly for military use, the off-road vehicle was released to the civilian market due to market demand.

Chronology
Successor	Hummer H2

The vehicle was initially known as the "Hummer"; however, under a 1999 deal, GM bought marketing rights to the Hummer name and called it the Hummer H1.[2] At the time, GM began marketing the Hummer H2 that was also assembled by AM General on a modified GMC Sierra 2500HD chassis. AM General continued to build the H1 and Humvee in its Mishawaka, Indiana facility. GM stopped marketing the H1 in 2006 model year but AM General continued production of the military Humvee versions.

History

Originally released in the civilian market March 14, 1992, the Hummer H1 became known from photographs published during Operation Desert Storm and the enthusiastic promotion by actor Arnold Schwarzenegger.

AM General 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 took effect in 2007. The final model year of 2006 had the most powerful engine and improved fuel efficiency—about 10 mpg_‑US (24 L/100 km; 12 mpg_‑imp).[3]

Specifications

The Hummer H1 was available in three major variants: a convertible-like soft top, a four-door hard top Sport Utility Truck and an "Alpha Wagon" body version. Less known variants were a two-door pickup truck 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 SUV versions were the last types available to individual consumers.

There were five engine types and three automatic transmission types available. Typical engine/automatic transmission combinations included:

• 6.2 L GM Diesel V8/GM TH400/3L80 3-speed
• 6.5 L GM Diesel V8/GM 4L80-E 4-speed
• 5.7 L (350 ci) L05 gasoline V8 TBI/GM 4L80-E 4-speed
• 6.5 L turbo GM Diesel V8/GM 4L80-E 4-speed
• 6.6 L turbo Duramax LLY V8 turbo Diesel/Allison 1000 5-speed (model year 2006)

The Hummer H1 shares some common driveline parts with the HMMWV. These include brakes, axles, frame and major body panels (hood, tailgate and quarter panels) are shared between the HMMWV and Hummer H1. All H1s and HMMWVs were produced on the same assembly line; of which the civilian H1s were painted and finished in a separate building.

The H1 models feature a wide track. They can ford 30 inches (76 cm) of water and climb a 22-inch (56 cm) step. Stock ground clearance of 16 inches (41 cm) is due to the driveline components inside a channel in the wide central space between the left and right seats. Approach/departure angles are 72/37.5 degrees. A Central Tire Inflation System (CTIS) controls the tire air pressure allowing lower tire pressures for off-road and higher tire pressures on-road.[4]

Other features include inboard brakes and portal gears to position drivetrain's half shafts higher for greater ground clearance. The radiator is mounted high, sloping over the engine on a forward-hinged hood. The air intake is high, enabling the H1 to ford waist-level water. Optional are magnesium-aluminum alloy or rubber inserts for run flat tire ability.[5] Other options include leather seats, a winch kit, and running boards.[5]

2006 Hummer H1 Alpha

The "Alpha" was a re-engineered H1 equipped with GM's Duramax Diesel and 5-speed Allison transmission. The previous turbo-diesel engine lacked power.

The update program commenced in late 2002 with production launch in fall of 2004. To fit into the H1 engine bay, 23 engine component changes were required as well as a 2.0 in (51 mm) body lift to accommodate the taller engine and its turbo housing (a prior 0.5 in (13 mm) lift had been done for MY96 to accommodate the turbo on the 6.5L engine). The 8th digit of the VIN is 3, setting this version of the 6.6L Duramax apart from the versions used in pickup trucks.[6] The GMT560 engine output was 300 hp (220 kW) and 520 lb⋅ft (705 N⋅m) of torque. The engine was equipped with cooled exhaust gas recirculation and an internal engine oil cooler, thus, requiring a 40 percent heat rejection increase to engine coolant. Because space was limited between the air-lift brackets that protrude from the hood, the fan system was modified by putting it directly under the cool pack and driving it through a special gearbox directly off the crankshaft damper pulley. Several other cooling system modifications were required to assist with cold starting from −30 °F (−34 °C).

Other major modifications included the use of special high-strength steel in the chassis frame, a more powerful steering gear; quieter axle differentials, redesign of the geared hubs to use quieter helical gears, new induction, exhaust and electrical power systems; and re-engineering of the fuel supply and filtration system.

The Duramax engine delivered more torque at lower engine speeds than the 6.5L, combined with a lower gearing ratio (about 44.5 to 1 in low lock) made the vehicle more powerful. Other changes included centralized tire inflation and a new interior.

Production launch was early in 2005 and continued until production ceased in mid-2006. All vehicles built during this time are classified as model year 2006 (10th digit in VIN is a 6.)

The program was cancelled May 12, 2006, because GM decided to withdraw technical and financial support for future engineering and recertification.

The Hummer brand

On June 2, 2009, General Motors attempted a sale of its Hummer brand to a Chinese company, Tengzhong, as part of its bankruptcy settlement. GM stated at the time that it hoped the sale would save about 3,000 jobs in the US.

On February 24, 2010, General Motors announced that the company was shutting down its Hummer brand due to Tengzhong withdrawing its bid. Tengzhong stated that the bid was withdrawn due to a failure to get approval from the Chinese government.[7]

On January 30th, 2020, General Motors announced the revival of the Hummer nameplate, which would be used as a new electric off-road vehicle sub-brand within its GMC brand. The reborn Hummer, now known as the GMC Hummer EV, will have two variants, an SUV and a truck ("SUT"), with top variants reaching 1,000 hp from three electric motors.[8]

While there was no 2005 model year Hummer H1, the 2006 model year H1 Alphas were manufactured in both 2005 and 2006. 448 H1 Alphas were produced from January through May 2005, and 281 H1 Alphas were produced from September 2005 through May 2006, when the production for the Hummer H1 officially ended.[9]

Der Hummer H1 ist ein Geländewagenmodell des US-amerikanischen Militär-Herstellers AM General. AM General verkaufte die Markenrechte „Hummer“ an General Motors, die die Nachfolgemodelle auf den Markt brachten. Der Hummer H1 wurde bis zur Einführung des H2 nur als Hummer (ohne Namenszusatz) bezeichnet. Im Jahr 2006 wurde die Produktion eingestellt. Bei der Avtotor in Kaliningrad wurde der H1 Alpha über 2004 hinaus für den Vertrieb innerhalb des russischen Marktes produziert. Der Hummer wurde vor allem durch den Einsatz seines militärischen Vorbilds HMMWV während des Golfkriegs weltbekannt.

L'Hummer H1 è un veicolo a quattro ruote motrici basato sul modello M998 HMMWV Humvee, creato dal produttore statunitense AM General. Il veicolo è stato prodotto dal 1992 al 2006 ed è stato il primo di quella che è diventata la linea Hummer. Originariamente progettato rigorosamente per uso militare, il fuoristrada è stato rilasciato sul mercato civile a causa di un forte interesse di mercato. All'inizio della sua carriera era noto come "Hummer"; tuttavia, in base a un accordo del 1999, GM acquistò i diritti di marketing per il nome "Hummer" e chiamò il veicolo Hummer H1.[2] GM ha smesso di commercializzare l'H1 nel 2006, ma AM General ha continuato la produzione delle versioni militari Humvee.

[ru] Hummer H1

Hummer H1 — гражданский внедорожник на основе M998 Humvee, который был создан AM General (англ.). Автомобиль выпускался с 1992 по 2006 года, и был первым, произведённым в модельной линии Hummer. Первоначально он был известен только как «Хаммер», однако в 2002 году на совместном предприятии General Motors и AM General, GM начал продавать Hummer H2, который был построен на шасси Chevrolet Tahoe. Именно в этот момент Hummer получил обозначение Н1. Для коллекционеров наиболее желаемой моделью является H1 Alpha, произведённой в свой последний модельный год — 2006. Модель отличалась самым мощным двигателем и, соответственно, выделяющимся расходом топлива в модельной линейке. В целом, у модели H1 было очень ограниченное производство транспортных средств.
