What's New for 2006

There are no significant changes to the 2006 Hummer H2.


The Hummer H2 marked the beginning of a whole new era for both AM General and General Motors. For those who aren't familiar with the former, it's a company that was awarded the original contract to build the Humvee military vehicle. When the Humvee became a household name thanks to its prominent role in Desert Storm, AM General decided to capitalize on its popularity and build a civilian version known as the Hummer.

With its unstoppable off-road ability and rugged military styling, it isn't exactly your average sport-utility, but its unique persona has helped make it a hit with wannabes and movie stars alike. Unfortunately, the Hummer's transition from all-purpose military vehicle to daily driver wasn't perfect. Despite its imposing size, there is barely enough room for four, and the interior ergonomics are poor. Although the suspension allows it to climb over just about anything, negotiating traffic in the nearly 3-ton beast isn't much fun. So how does General Motors figure into the equation? Realizing that AM General had a household name for a product that few could afford, GM stepped in and bought the rights to "Hummer" in 1999. It doesn't own AM General, nor does it build any of the vehicles.

What the General did do, however, was design a new vehicle called the Hummer H2 using its extensive inventory of existing truck and SUV parts. The result was a concept-to-showroom development time of just 16 months, almost unheard of in an industry where new designs typically take three to four years to hit the marketplace. The idea for the H2 is fairly simple. Take the unmistakable look and feel of the original Hummer and infuse it with the comfort and drivability of more traditional sport-utility vehicles. More importantly, do it without sacrificing any of the capability that made the H1 (now the official name of the original) unique. In other words, the Hummer H2 couldn't be just a rebadged Chevy Tahoe. To accomplish this, the H2 uses a frame made from both heavy- and light-duty truck components fortified for severe-duty use. The rear suspension is a live axle, five-link design similar to the Suburban and Tahoe, while the front end is a fully independent design with torsion bars.

Nearly all of the H2's underbody components have been tucked in above the frame to keep them out of harm's way, and with 10 inches of ground clearance and a vast array of underbody armor shielding vital components, the H2 is well equipped for hard-core off-road adventures. Almost all of the convenience features found in GM's SUV and truck lineup can be found in the H2. From dual-zone automatic climate control to a Bose audio system to the OnStar communication system, the H2 is loaded to the hilt with standard features. After four years on the market, though, the 2006 Hummer H2 doesn't turn quite as many heads as it motors through suburbia. Unless you're a serious off-roader, you'll likely find that this Hummer's unwieldy size and big thirst make it impractical, even unappealing, to drive on a daily basis.

Body Styles, Trim Levels, and Options

The Hummer H2 comes in only one body style and one trim level, but two major packages known as the Adventure Series and the Lux Series add numerous options. Features like dual-zone automatic climate control, a driver information center and OnStar are standard equipment, along with power everything and a keyless entry system. The Adventure Series package adds a self-leveling rear air suspension along with an upgraded audio system, carpeted floor mats, tool and first aid kits and a front brush guard. The Lux Series package doesn't include the air suspension, but it does add uplevel leather seating, a chrome appearance package, a brushed-aluminum roof rack, tubular side steps and the Adventure package's audio system and floor mats. Other stand-alone options include heated front and rear seats, a power sunroof, an overhead light bar and a DVD-based navigation system.

Powertrains and Performance

All H2 models are powered by GM's 6.0-liter V8 rated at 325 horsepower and 365 lb-ft of torque. A heavy-duty 4L65-E four-speed automatic transmission handles the shifting chores, while a full-time dual-range transfer case distributes the power to the individual driveshafts. Advanced features include a driver-selectable rear differential locker and a drive-by-wire throttle setup that changes sensitivity when low-range gearing is selected.


The Hummer H2 comes standard with an ABS/traction control system. The advanced traction system allows the H2 to propel itself even if only a single wheel has grip, while driver-selectable settings fine-tune the system to respond to varying road conditions.

Interior Design and Special Features

Unlike the awkwardly configured H1, the H2's interior is arranged like a typical full-size SUV. Power-adjustable captain's chairs reside upfront, while a three-passenger bench seat makes up the second row. The overall design emphasizes the H2's rugged personality, with exposed attachment bolts and an aircraft-style shift lever, but standard equipment like dual-zone climate control and a nine-speaker Bose sound system remind you that the H2 is a thoroughly modern vehicle.

Driving Impressions

Despite being slightly downsized compared to the original, the 2006 Hummer H2 still feels massive on the road. The ride is slightly stiffer than that of a Suburban or Tahoe, but not so much as to be uncomfortable. The H2's off-road prowess is easily the best in its class, with steep approach and departure angles, plenty of ground clearance and ample wheel travel. Power from the big V8 is watered down by the vehicle's substantial mass, and gas mileage often drops to the single digits during stop-and-go driving.

Vehicle: 2006 HUMMER H2 4dr SUV 4WD (6.0L 8cyl 4A)

By far the very best vehicle I have ever owned! It's a criminal thing that these beautiful machines are no longer in production. Fits All 3 of my children in the middle bench seat with ease and they love it! good sized cargo area and even more if your H2 is fitted with the spare on the outside-mine is. And removal of the single rear seat is easy out and easily put back in. My wife loves driving it as well. And.....I love to go fresh water fishing and the area I fish it not easily accessed as it has extremely soft sand and some hills to climb. No problem for my H2!....Neutral then change to low 4 in we go! Love this vehicle and it's an eye catcher! All black exterior and interior!

Used low mile h2

Vehicle: 2006 HUMMER H2 4dr SUV 4WD (6.0L 8cyl 4A)

Was looking for a vehicle for the family - wife and I and three kids from 10 yrs to 6 weeks old. We pull an RV and I wanted full-sized SUV. I knew MPG would not be fantastic regardless of the model. With the H2 I have more capability than I will likely ever need, but emergencies do arise. With the large size and weight I feel my family is very safe inside. Ride has been MUCH better than I expected. Very comfortable. Don't know what vehicle the "professional" reviewer drove but this SUV has tons of room. I can easily sit three adults across the back seat. Check out pre-owned certified H2s still avail in the 20-30K miles for reasonable prices. Same as or less than a similar Tahoe.

Vehicle: 2006 HUMMER H2 4dr SUV 4WD (6.0L 8cyl 4A)

I bought one (pewter metallic) intending to use it for a weapon development project, but as soon as I sat behind the wheel I fell in love with my h2, my daughter, 27 at the time immediately wanted to trade in her Lexus suv for black h2. Since I bought them I kept accessorizing them. These cars are nothing short of amazing.

Very best suv ever!

Best, safest, super great looking and most dynamic vehicle we have ever owned and will chose to own nothing but an H2. Aside from the fact that it is not a fuel efficient truck, this is a challenge most certainly, and that it is missing a rear view camera which should be a mandatory factory installation, this truck is a must see and drive and get to know! Thanks GM!

Vehicle: 2006 HUMMER H2 4dr SUV 4WD (6.0L 8cyl 4A)

Having owned some very extravagant & exotic vehicles, there is nothing like a Hummer H2! I'm embarrassingly proud to own such a magnificent & unmistakable machine! I'd never even ridden in, let alone driven one before I bought online, sight unseen 2000 miles away - no disappointments! If you're looking and thinking about owning one - take the leap of faith and treat yourself!

The holy grail

Vehicle: 2006 HUMMER H2 4dr SUV 4WD (6.0L 8cyl 4A)

I would never ride in or touch a Hummer until I could finally afford one. It's like the Stanley Cup. You don't touch it until you win it. That day came a few weeks ago for me and it has been incredible! Love driving it, getting looks, surprisingly easy to park and so comfortable. I recently picked up my 60 something parents from the airport and they had no trouble getting in or out and thought it rode better than their own vehicles. I have always loved the look of the H2 and and now enjoying driving it every day. There is no comparison, it is the best.
