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.

Currently, five engine types and three automatic transmission types are available. Typical engine/automatic transmission combinations include:

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]

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 coolpack 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.

I'm on my 2nd used H3 and I'm not even surprised with the intro clip hahahaha

When we were shopping for our G Wagon last year i decided to explore some other options and started looking at Hummer H1's. I was floored at the condition of vehicles being offered for sale by seemingly reputable dealers. Torn CV boots, terrible resprays, and lack of service records. Caveat emptor is the law of the jungle when purchasing exotics (or any vehicle for that matter). The best money spent is on a PPI from a reputable shop like Predator Inc.

I've never been so hooked on a series on youtube.

That is unbelievable, who on earth would think that any of this mess is the right way to repair/modify my dream truck, my favorite bad bits on this H1 is that dual fuel filter/pump setup right where a chunky off road tire is that will snag the wiring on the tread lugs, those holes cut underneath the top shock bolts where you can see the overcut lines from a round cutoff wheel, that drilled hole in the fuel tank for a return line so you'll have the worst fuel economy possible on an H1, the mass of duct tape and rubber on the windshield frame and on top of the washer bottle and the rats nest of wires that was underneath it, that jerry can paint mark shows what type of mind was working on this H1, no parking brake fitted, that push button engine start makes no sense, you guys must cringe at this considering your workmanship and reputation, I'll be watching every vlog as usual.

How much do they charge to fix my mom's Hummer h3 sunroof leaking problem I need the drains are bad and and I think the sunroof leaks too

Texas BEAST says:

I thought you were gonna say it had a 1500 lb ATV winch.

Could you put sequential twin turbos in these, for added low and AND high end gains? If anything, I would want one skewed toward low end first, anyway.

Matthew Meuleman says:

did you get that from Andrew Camarata

REAL4wd says:

Wow just wow

Dark Rain says:

These hummers are getting rare so its cool that it is being saved but JESUS that hummer needs a good acid bath.

suckamc3232 says:

To play it safe you need to take a part the the truck too dangerous not too especially if you sell don’t wanna be responsible if someone gets hurt

Larry Liedner says:

Did you pay for this disaster or get paid to haul it away

bigkofjustice says:

And you are dead on right with stereo shops, I've seen strange shit including one guy just tapping the ECU power line to install a stereo and CB and the owner was wondering WTF every time he transmitted his truck stalled out…
