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.

That EXACTLY is my dream car.....Santa are u listening?

🎅🏻🎄

[@JohnJohnson-ze1gg]

Sidenote to anyone who may find this vehicle over priced. There is an IRS code called section 179. If the suv, pickup or van weighs in at 6,000 lbs or more. As long as it is registered for that business. They even include luxory brands now. The IRS lists them. You can recieve up to full reimbursement

[@JohnJohnson-ze1gg]

Does Eric have his own YT channel or where can i find him online? I love racing. NHRS, offroad, F-1, i even tolerate NASCAR now and then, only because they own IMSA. IMSA, is my favorite motorsport in the history of cars. The ultimate in man, machine and team. What a treat😁😁😁

[@r0tb3rt]

I wish that bumper would be legal here in Germany.

[@NKPGarage]

Amazing build!

[@PredatorInc]

Thank you and thanks for watching!

[@rooster7658]

Legit bad ass machine

[@texasbeast239]

Like gas prices. They shot up so high that we're still not back down to where we were before the coof, either. Those are some magic numbers: 1000 and 2000. Whoah.

[@TEAM6USA]

gas is 2,49 in texas. Not bad.... But i miss the 1,50

[@hummerfamily6092]

Love, love, love it

[@PredatorInc]

Thanks!!!

[@cornbreadsbest]

That widebody corvette is twin turbo 1500hp lmr built.. that hummer is so nice.

[@PredatorInc]

@tjhunt_ C8 that's up for sale.

[@hawaiianpunch6534]

I love that white ACR.

[@PredatorInc]

Yah she's a sick car!!!

[@chesspiece81]

Since GM makes a 10 speed Allison now are there any plans to use them in the H1 behind the Duramax?

[@PredatorInc]

Yes however most all customers prefer the older engine.

[@JohnJohnson-ze1gg]

Outside of California, is it possible to mate a new engine/transmission pair minus DEF if it is in a truck that predates the EPA mandate?

[@starksinc1]

What kind of MPG is a 1000 HP getting? I just sold my 1998 H1 wagon . I am looking to pick up a custom 2006 Alpha within the next year built by predator. So what is a 750 or 1000 hp mpg getting. Should be getting more with the increased hp correct?

[@Noah-er9on]

Higher horsepower is technically more fuel efficient, but it uses more fuel. Also worth noting that if you drive fast, you're going to blow through fuel. I bet that 1000 horsepower gets single digit MPG when on the most aggressive time, but it makes up for it with the smiles per gallon

[@marklagac8080]

I knew I saw Ryan driving around my neck of the woods.

[@PredatorInc]

Haha, that's funny! Should have swung by!!!

[@rakyat6223]

Why you need 1000hp? What you will pull by it?

[@PredatorInc]

Murica, that's why! 🇺🇲👍

[@makewithmegma]

🔥💕👌👍

[@rand0mGT]

How was the in n out?

[@ALink2Zelda]

yolo

[@sanchoCA]

How much was it sold for?

[@PredatorInc]

I believe its listed for $200K at WCEC

[@stanislous137]

How much does it go for?

[@PredatorInc]

I believe this was listed for $285k at the dealer.

[@butchcantara1497]

Diesel engine?

[@PredatorInc]

Duramax diesel eng.

[@missingremote4388]

Slow-ride take it easy

[@don_panic]

0 - 100 km/h measure please

[@muddyturbos1663]

There is absolutely no way this truck makes 1000hp with that intercooler piping and single VGT turbo... Not even close...

[@JohnJohnson-ze1gg]

Ahh, that's your professional opinion is it professor?

[@x-tremehummerperformance6511]

Yeah…not making 1000hp with setup unless there is a lot of nitrous hidden somewhere 😂

[@masterclassanonymous1292]

I am concerned about Eric's arm has anyone checked? He may have broken it patting himself on the back.

[@DurinThe_Deathless]

Hilariously out of touch

[@PredatorInc]

In the absence of any other information, this is comically irrelevant. 🤦🏻‍♂️

[@JohnJohnson-ze1gg]

​@@PredatorInccompletely agree

[@danielpork2638]

Thumbs down, drive it nexttime'

[@Countrysideboy247]

I would have this over the hummer EV anyday, any guess what's the 0-60 btw?
