Following are some of the most unique features and options available on Hummer H1s and H2s. These characteristics make Hummer stand out above the rest:

  • Run Flat tires where rubber spacer assemblies are placed inside each wheel enabling you to drive on one or more flat tires for up to 30 miles at 20 mph.
  • All H1s are equipped with a Central Tire Inflation System. CTIS is an option on H2s. It enables the driver to inflate or deflate the front tires together, the rear tires together, or all 4 tires at the same time -- all from within the cabin by flipping a switch. This feature is ideal in off-roading situations. In 1994 and later models, there is also a connector at the compressor so you can inflate other tires, accessories, etc.
  • Tire pressure for normal driving in a Hummer is 26 psi front, 28 rear. With CTIS, air pressure can be increased up to 45 psi for heavy loads. Typical offroad tire pressure is 20 psi, however for driving in sand, mud, and deep snow, air pressure can be reduced to 10 psi, resulting in a very large footprint. An alarm sounds if pressure falls below 8 psi.
  • Since the Hummer is over the clearance height limit, by federal law it is required to have clearance lights along roof. There are amber marker lights on the front exterior of the cabin and red marker lights on the rear of the cabin.
  • Dual fuel tanks with 25 gallons in the primary tank and 17 gallons in the reserve tank.
  • The front end and rear end overhangs were reduced to a bare minimum for the best possible approach and departure angles off-road, so you won't scrape your bumper as you approach or descend an incline.
  • Unique traction control system that prevents wheel spin called TorqueTrac4. TT4 automatically applies the brakes to the wheel that is spinning, allowing traction to take place on the wheels that aren't spinning.
  • For individualized front-seat comfort, the standard dual-zone front controls allow the driver and front passenger to set individualized temperatures with as much as a 25-degree Fahrenheit difference.
  • Driver Information Center provides up to 28 warnings for specific vehicle functions and allows two drivers to personalize their driving environment, taking advantage of separate memory settings.
  • Large power-tilt and power-folding, heated outside rearview mirrors that come with a curb assist feature that tilts them down for easier parking.
NOTE: While not all of the above features appear on all Hummer H1 and H2 models, most are standard on at least one model year, others may have been added as standard features to later model years.

Pros: Best Reasons To Own A Hummer
Cons: Worst Things About Hummer H1s and H2s
Little-Known Facts About Hummers

In addition to all of the highly unique features mentioned here, following are some of the best reasons to consider owning a Hummer(some major, some minor). Consider these before you decide to purchase an H1 or H2 of your own:

  • It's very large, yet handles with more precision than some smaller trucks.
  • Turning radius (26.5 feet) is good compared to other large sport-utes.
  • It can travel places other vehicles cannot. It can go virtually anywhere: through rivers, mud, snowdrifts, and over obstacles of many sizes.
  • Doesn't ride like a tank.
  • OnStar system is standard.
  • A more sophisticated 4WD system than most SUVs, including a lockable differential and traction control that only requires one wheel to have traction, plus a second mode for mud or sand driving.
  • Full-time 4WD means powerful 4-wheel drive capabilities at all times.
  • It's an attention-getter. About the only thing a Hummer is NOT capable of is anonymity! Everyone asks about it, wants to know what it's like, wants a closer look, wants to sit in it... and you're 4-wheeling friends will beg you spend more time off-road in it.
  • Stock radio is impressive. The Bose (cassette/CD/radio) system uses noise canceling technology to eliminate road, wind and other distractions while providing clear sound from nine speakers.
  • Feeling of safety and security on the road (and off).
  • Fun to drive.
  • Great factory winch option.
  • Steering wheel controls that permit drivers to select radio stations, change modes from radio to CD and control volume.
  • Head room and leg room are adequate for taller drivers and passengers.
  • 60/40 second-row seat is easily wide enough for 3 adults.
  • The 2nd row seat can also be folded down to increase cargo space.
  • Back seat passengers get their own climate controls, vents, and stereo controls for two headphone jacks.
  • The optional 3rd row seat flips forward easily, so cargo space can be created in an instant. This seat can also be completely removed, creating even more cargo space.
  • Light-sensitive inside rearview mirror with compass and outside temperature display.
  • Rear seats, fold, tuck, swivel and can be removed (although they’re quite heavy).
  • The seats can adjust be adjusted to suit a wide variety of drivers.
  • Lots of opportunities to participate in Hummer outings all across the country (many of them are free). These are great for trying out Hummer's offroad capabilities, and getting to know other Hummer owners.
  • Wheels are positioned at the extreme corners, providing extra stability on-road and preventing tipping off-road.
  • Wider tires with extremely wide tread for ultimate traction.
  • A stable vehicle, with high clearance and a low center of gravity at the same time.
  • Despite the poor gas mileage, the Hummer comes with a 32-gallon gas tank, so it will go just as far on one tank of gas as most other vehicles.
  • Unquestionably one of the best choices for an off-road vehicle. Even with a stock Hummer, you're able to go places that only modified 4x4's can go.
  • Made in America.

In addition to all of the highly unique features mentioned here, following are some of the downsides of owning a Hummer (some major, some minor). Consider these before you decide to purchase an H1 or H2 of your own:

  • Replacement tires of this size carry an equivalent price tag.
  • Takes some time to get used to driving a vehicle nearly 7 feet wide.
  • Narrow roads, parking, and trying to fit it into your garage each pose unique challenges.
  • Insurance is higher than most vehicles.
  • Gas mileage is poor (roughly 12mpg), especially when used as a daily driver.
  • Maintenance costs are high.
  • Depending on where you live, it might be difficult to find qualified mechanics.
  • Noisier road ride than many other SUVs.
  • Not enough A/C vents inside.
  • Difficult to pass other vehicles on narrow roads.
  • Resale value isn't very high.
  • Strange as it may sound, the stares and attention can get annoying over time.
  • Expensive to buy, and even more to keep.
  • Doesn't have much pick up & go. Seems lethargic taking off after a complete stop, making it hard to keep up with other cars. Top speed is around 90mph.
  • Priced too high for most people.
  • Despite the size of the vehicle, there's not much cargo space inside.
  • Towing capacity of 7,000 lbs. is not best in class for an SUV of this size.
  • Rear visibility is particularly difficult through the small back window.
  • Front visibility over the tall, boxy hood can be a challenge for drivers under 6 feet tall.
  • Difficult for shorter drivers to get into the vehicle.
  • Can only seat 6 passengers comfortably (counting the optional 3rd row "seat" that takes up the cargo space).
  • What appears to be a roomy interior actually feels somewhat cramped once seated inside.
  • Limited cargo space, even with the 3rd row seat removed. Maximum cargo space is listed as 86.6 cubic feet with the 2nd seat folded down, which is less than other full sized SUVs (Acura MDX, Honda Pilot).
  • You can choose any color you want for the inside, as long as it's "wheat".
  • The driving position takes some getting used to, as the upright windshield is very far away, and it's tricky determining the distance between the front of the vehicle and other objects.
  • The huge, full-sized spare is mounted in the rear cargo area, taking up the entire left side of this valuable space.
  • Even with the spare tire removed, a left-side third-row seat is not available. So the most you'll ever seat in a Hummer is 6 people.
  • Only comes with automatic transmission, so you'll have to leave the shifting to the Hummer.
  • Designed like a box with wheels.
  • Since a Hummer requires high ground clearance, many engine and transmission components are placed inside the cab itself -- taking up to 3 feet of space in some places.
  • You cannot attempt driving through tight places or maneuvering through obstacles due to its shear mass.
  • Due to its massive weight, it can be slow to stop in emergency braking situations.
  • Because the rear window is so high up, visibility using the rear view mirror is not ideal.
  • If you need to seat more than 5 people, then you must purchase the 3rd row seat option to seat one more person.
  • Knowing the height of your Hummer is crucial to verify whether or not you can fit through some drive-thru's.
  • The windows and windshield seem unusually small on a vehicle of the size.
  • Unless you really get stuck, the Central Tire Inflation System is a feature that’s probably more trouble than it's worth, since the extra large tires take so long to deflate and then re-inflate.
  • There are large blind spots. Cars are practically invisible looking over your shoulder and through the rear window.
  • Lack of standard safety features: child safety locks, child seat tethers, side air bags.
  • Difficult to park in tight spots. Straight in and straight out are your best bets.Interior of a 2004 Hummer H1 GM Worst Things About Hummers In addition to all of the highly unique features mentioned here, following are some of the downsides of owning a Hummer (some major, some minor).

    • AM General started making High Mobility Multipurpose Wheeled Vehicles (or Humvees) for the U.S. Army in 1983. They started building the civilian models (or Hummers) in 1992.
    • In 1999, General Motors acquired exclusive ownership of the Hummer brand name and the marketing rights from AM General, but AMG still continues to manufacture the H1 Hummers for the civilian market. The H2 is GM's own version of the original Humvee, and it is built on GM's Suburban frame.
    • A Hummer is classified as a Class 3 truck, but it does not require a special license to drive it.
    • All Hummer dealers are required (as a condition to holding the franchise) to organize 4 Hummer off-road events per year!
    • Unlike most SUVs, this vehicle is geared for off road use. Therefore, what most perceive as poor engine speed during routine driving actually results from the fact that Hummers were not designed for driving on in town and on highways.
    • The Hummer is a tiger offroad. The H1 can climb a 22-inch vertical wall, navigate a 60% grade, traverse a 40% grade side slope fully loaded (with nearly 3,500 pounds of payload), and operate in up to 30 inches of water. The H2 can climb a 16-inch vertical wall, navigate a 60% grade, traverse a 40% side slope, and operate in up to 20 inches of water.
    • HUMVEE or HUMMER?… The basic vehicle produced for military use is called a High Mobility Multipurpose Wheeled Vehicle (or HMMWV), which the military eventually called a HUMVEE for short. When AM General introduced a civilian version of the HMMWV, it was officially called a HUMMER.
    • The H2 starts with your basic GM truck platform. It's the same one introduced on Chevy and GMC pickups in 1999 and is today on the Suburban, Tahoe, Yukon, Escalade and other GM full-size trucks and sport-utility vehicles.
    • All Hummers have automatic transmissions, even the military ones. Therefore, no stick-shift option is available.
    • While a Hummer is equipped to drive through water up to 30 inches deep (most components are sealed against the elements), it's not an amphibious vehicle, or a submarine, nor can it float. In fact, it is designed to take on water in order to avoid floating, all the while maintaining traction underneath.
    • The Hummer is designed in such a way that when fording through deep water, a significant amount of water will actually enter the vehicle, only to be released afterwards through the drain plugs in the floors.
    • While military Humvees have a snorkel kit extending the exhaust and air intake to roof level, making it possible to operate in 60 inches of water, Civilian Hummers cannot use the snorkel kit because the dash, fuses, alternator, power steering cap, transmission controller, radio, and engine controller are not waterproof.
    • As a Class 3 truck, Hummers are exempt from many DOT safety regulations such as passive restraints and third brake lights. However, they do have to have padded dashes, collapsible steering columns, steel roofs and doors, and lights (including clearance lights on front and rear).
    • The EPA does not release gas mileage ratings for Hummers, because they fall under the classification of “heavy vehicles” (similar to shuttle buses and ambulances).
    • Approximately 1000 civilian versions the original Humvee are built each year at the South Bend, IN facility.

    You'll either love it or you'll hate it. It's not the most quiet, most plush, smoothest or fastest vehicle out there, but it wasn't meant to be. It's not the wisest choice for a daily driver, but few buy a Hummer for that purpose.

    Truth is, the Hummer is a symbol more than anything. It's all about image and attitude. It's purchased more for looks and brawn than practicality and purpose. So, if you're looking for another way to get noticed…the Hummer could be just what you've been waiting for.

    Realistically, if you can afford one (initially, as well as repeated maintenance), and you plan to spend most of your time in it off-road, then by all means… buy one! The Hummer will likely be your best trailblazing machine ever. It's a great off-road vehicle... if that's what you're looking for.
