(from GM Press Release) No
matter whether H1 customers choose the 4-Door Wagon model or the 4-Door
Open Top, they'll rest assured knowing their vehicle can tackle the most
difficult terrain. That's because the HUMMER H1 is no SUV afterthought.
It wasn't designed to be satisfied with tackling 22 inches of snow or
curb-high obstacles. In fact, it wasn't "designed" as much as it was
"engineered." More specifically, it was engineered to meet the rigorous
demands of the U.S. armed forces who needed a vehicle with power,
agility and durability like nothing in existence. Strip away some
refinements and creature comforts, and the HUMMER H1 is still the "HUMVEE"
so trusted and respected by the military.
Where does one start in describing H1's off-road capability? How about
its 16-inch vertical ground clearance - almost double that of any other
4x4. Let's not overlook H1's dramatic approach and departure angles of
72 degrees and 37.5 degrees, respectively, or the 17-inch aluminum
wheels shod with 37-inch tires. You may never encounter the actual need,
but there's a degree of comfort in knowing this vehicle can ford a
30-inch deep body of water.
Four-wheel drive is standard and features TorqTrac 4 technology. It
automatically reduces tire spin on severe terrain or slippery surfaces
by applying the brake to the spinning wheel. This allows the
differential to redistribute torque to those wheels with traction. As if
that weren't enough, H1 owners may opt for the Off-Road Adventure
Package. This package is the ultimate in off-road equipment, and
includes a front and rear Eaton ELocker locking differential. Activated
instantaneously at the push of a button, the front and rear
differentials can be locked for optimum slow-speed capability in
climbing over large rocks or up long, steep grades. The Off-road
Adventure Package also includes a 12,000-pound winch kit, 17-inch,
two-piece aluminum wheels with dual beadlocks, and Goodyear Wrangler
MT/R tires. Goodyear GSA tires can be substituted for the MT/R tires, if
the customer so desires.
Included as standard equipment on every H1 are a Central Tire Inflation
System (CTIS) and a Runflat Tire System. CTIS enables H1 owners to
adjust tire pressure on the move and adapt to varying terrain. For
example, if additional traction in snow, loose sand or mud is required,
the H1's tires can be deflated with the push of a button from inside the
vehicle. Another push of the same button when traction conditions have
improved re-inflates the tires. H1's Runflat Tire System, meanwhile,
enables drivers to continue driving on a deflated tire for up to 20
miles at 30 mph - ideal when the nearest service station is not right
around the corner.
Further aiding peace of mind while off road are H1's low center of
gravity, long wheelbase (130 inches) and nearly 72-inch track. The
result is a vehicle that is extremely stable - on- and off-road.
While H1 is rightly considered the ultimate sport utility vehicle, it's
also adept at overcoming the obstacles commonly found in the asphalt
Interior creature comforts include an instrument panel specifically
designed to place major controls and switches within easy reach of the
driver. Audiophiles will enjoy the standard Monsoon audio system with an
integral six-disc CD changer. Other H1 features designed to enhance
convenience, comfort and safety include a heated windshield, tire
pressure gauge (part of CTIS), driver's express-down window, heated
power exterior mirrors and remote keyless entry.
The HUMMER H1 is so well-equipped that very few other options are
available. In addition to the Off-road Adventure Package, leather seats
with heating elements for the driver and front passenger are among them.
A host of dealer-installed accessories are also available, enabling H1
owners to customize their vehicle to best meet their specific needs.
HUMMER H1 is powered by a retuned 6.5L, turbo-diesel V-8 engine that for
2004 delivers 205 horsepower (152 kw) at 3400 rpm and an impressive 440
lb.-ft. (596 Nm) of torque at 1800 rpm. That's 10 horsepower (7 kw) and
10 lb.-ft. (14 Nm) of torque more than the 2003 powerplant. Yet enhanced
performance is only part of the engine's story. The retuning also
enables the 6500 to meet the more stringent emission requirements
starting in 2004. It's mated to GM's Hydra-Matic 4L80-E electronically
controlled four-speed automatic transmission. Over time, this
transmission monitors the customer's driving technique and adjusts for
driving style. The New Venture Gear Model 242 transfer case enables the
driver to customize the drivetrain configurations to match virtually any
H1 has a four-wheel fully independent suspension system and
variable-rate heavy-duty coil springs. The front suspension incorporates
a large stabilizer bar to improve handling and reduce sway when
cornering. The truck's four-channel ABS four-wheel power disc brakes are
mounted inboard as a component of the axle assembly, making them less
vulnerable to damage than conventional wheel-mounted components.
"There's still nothing else on the road today with the panache of the
H1," said DiGiovanni. "No other SUV can match its off-road capability
and no other SUV - and very few vehicles in general - have the
attention-grabbing styling of the H1. It remains the foundation upon
which to build the HUMMER future."
