HUMMER H2 SUT -- All the
capabilites of H2 ... and then some
HUMVEE is the original HUMMER, the cornerstone of the brand. In
2003, HUMMER introduced H2, reflecting an evolution of the brand
and making HUMMER more accessible to a wider audience. For 2005,
the HUMMER brand continues to evolve, thanks to the H2 SUT – a
vehicle with unmatched capabilities, and still every inch a
“Like its brother the H2 SUV, the SUT draws from its military
heritage as the next evolution of the HUMMER brand. The H2 SUT is
functional, versatile and almost endlessly reconfigurable,
exceeding even the most demanding consumer’s standards,” said
Michael C. DiGiovanni, HUMMER general manager.
HUMMER is the king of the mountain for off-road vehicles. The SUT,
like the H2 SUV, has unbelievable, class-leading, off-road
capability. This truck is untamed and built for individuals with a
rugged spirit because it can go anywhere and do anything.
“While the SUT certainly carries on the traditions of its
predecessors, it has a level of unique design, functionality and
capability that offers owners a sense of freedom that appeals to
their youthful, active lifestyles,” added DiGiovanni.
H2 owners can already carry passengers, cargo or a combination of
the two. With SUT, HUMMER adds even more flexibility.
When SUT owners have to carry four passengers, the bulkhead at the
rear of the passenger compartment remains upright, still providing
over 30 cubic feet of cargo-carrying capacity.
However, when cargo requirements dictate the need for more space,
the rear window can be powered into the Midgate, and the Midgate
and the rear seat folded forward, offering a 4-foot by 6-foot
Rubber bed mats help keep the cargo area clean, while a locking
hard tonneau cover provides cargo security. Both accessories may
be ordered individually, as may bed rail cover inserts and a
removable, locking cargo box. SUT owners may also customize their
vehicle with a host of other GM accessories.
“There’s more to the H2 SUT than merely cargo-carrying capacity.
At the push of a single button, the driver can lower all four side
windows and the rear window. Using a separate switch, the standard
sunroof can also be opened, giving SUT a truly open-air feeling,
like driving a convertible,” explained Roger McCormack, HUMMER
H2 SUT’s interior is as inviting as it is innovative. It features
Medium Wheat leather seats standard, or an uplevel Ebony leather
interior is available. Either leather-seating configuration
features eight-way driver’s and front-passenger seats, four-way
lumbar supports and memory settings for two drivers. Both front
seats also feature three heat settings for the seat cushions and
seatbacks. Heated seat cushions for the rear passengers are
included with either leather package.
The uplevel interior features an all-black appearance throughout.
Perforated leather is used on the instrument panel and the door
trim grab handles. Leather is also used to cover the console lid,
the door trim armrests and the door trim surround.
“To truly accentuate the Ebony leather interior we’ve given the
door sill plates an aluminum appearance, complementing the chrome
appearance of the aircraft-style shifter,” McCormack added.
The metallic look is also incorporated into the inside door
handle, which features a chrome finish. The result is an interior
that epitomizes luxury and precision.
for directions? Never!
The beauty of a vehicle such as the HUMMER H2 SUT is the ability
to go pretty much anywhere. And if the driver is unsure how to
“get there” – well, it’s not a problem, thanks to the available
touch-screen Navigation Radio. With the push of a button, the
navigation operation will instantly map routes with 2-D and 3-D
full-color map views on a 5.8-inch display screen, making
maneuvering on highways and streets effortless. Once the
navigation DVD is inserted and the address entered on the system’s
screen, a route map is generated and audio commands – with
step-by-step instructions in English or French – are provided.
The verbal commands tell drivers when to turn and alert them if
they stray from the calculated route; the system automatically
recalculates a new route from their current position if they make
a wrong turn. Additionally, drivers can instruct the navigation
system to plan a route using the shortest path or one using major
roads. Coupled with the standard OnStar system, the navigation
system provides additional security to drivers.
Providing uninterrupted listening pleasure while going “from here
to there” is the available XM Satellite Radio, featuring 100
coast-to-coast, digital-quality channels of original music, news,
sports and talk. Many of the channels are presented
commercial-free. Consumers can subscribe to the basic service for
$9.99 a month – less than the cost of a single CD.
inch a HUMMER
H2 SUT’s exterior is as rugged as its interior is refined. The
HUMMER DNA is quickly evident from the exterior design of the SUT,
embodying square shapes; flat, chiseled surfaces; hard peak lines;
and flat glass panes. These combine to create a significant amount
of interior room. The vertical glass opens up a broader front and
wider side view.
In a nod to the functional aspect of design, exposed components –
such as hood lift handles, hood latches and fasteners – give H2
SUT’s appearance an individually component-assembled quality.
Exposed components shout ruggedness and exemplify yeoman-like
functionality and workmanship.
The rear bumper also includes large, military, HUMMER-style
retrieval loops; the front bumper includes tow loops. Both bumpers
have access holes for the hitch receivers attached to the chassis
that can accommodate a winch, which can be plugged in, locked
(just like a trailer hitch) and hooked up with an electrical
connection, allowing H2 SUT to free vehicles mired in mud or
otherwise hopelessly grounded.
Both receivers accommodate a regular Class 3 trailer hitch,
providing additional flexibility for such tasks as pulling a boat
out of the water or backing a trailer into a tight spot.
Because it is based on the H2 SUV, the SUT enjoys short overhangs,
for radical approach and departure angles and exceptional ground
clearance for minimal impact on trails. The 17-inch wheels and
heavy-duty independent front suspension and five-link rear
suspension provide superior handling, carrying and towing
Powering the H2 SUT is GM’s 6.0-liter, Vortec 6000 V-8, which
delivers 325 horsepower at 5200 rpm and 365 lb.-ft. of torque at
4000 rpm. The Vortec 6000 is mounted longitudinally and mated to a
heavy-duty Hydra-Matic 4L65-E four-speed automatic overdrive
transmission with full-time all-wheel drive. “Exceptional off-road
capability and versatility in the SUT allows HUMMER owners the
ultimate opportunity for adventure,” said McCormack.
“We first introduced the H2 SUT as a concept vehicle in Times
Square with Arnold Schwarzenegger and Mayor Rudy Giuliani during
the 2001 New York Auto Show,” said McCormack.
The H2 SUT will be built at the AM General assembly facility in
Mishawaka, Ind., by the United Auto Workers Local 5, the oldest
UAW local union in the country. The H2 SUT will go on sale in the
second quarter of 2004.
General Motors and AM General reached an agreement in December
1999, in which GM acquired exclusive ownership of the HUMMER brand
SUT REDEFINES 'CAPABLE'
and “HUMMER” are synonymous. After all, how many other vehicles
can ford a stream 20 or 30 inches deep (H2 and H1, respectively)
or climb 16-inch vertical steps? H2 SUT is all of that, of course,
while also adding a higher level of versatility and fun to any
“The reconfiguration aspect of the H2 SUT greatly enhances its
versatility. SUT can be a fun and luxurious family hauler, a
practical truck or a little of both. And because it’s a HUMMER, it
can traverse the toughest terrain easily and comfortably,” said
Michael C. DiGiovanni, HUMMER general manager.
Capable = Versatile
H2 SUT can comfortably accommodate up to five people. It also has
60/40 folding rear seats, allowing drivers to conveniently carry a
combination of passengers and cargo inside the vehicle. Where SUT
really shines, however, is during those times when cargo
“The SUT features an open-back cargo bed. The open feature means
that tall items can be more easily transported,” explained Roger
McCormack, HUMMER product director. “What’s more is that the cargo
area is expandable.”
With the Midgate closed, the SUT offers more than 30 cubic feet of
space inside the cab. When even larger items must be accommodated,
SUT is up to the challenge.
“Extending cargo-carrying capacity is a very simple process in the
SUT. Fold the rear seats and fold the Midgate, and you have a
4-foot by 6-foot cargo bed and you increase your cargo-carrying
capacity to more than 52 cubic feet,” said McCormack.
For securing cargo, the bed has four tie-down provisions, each
capable of holding 500 pounds. Cargo security, meanwhile, can be
ensured with the available locking hard tonneau cover or the
locking cargo box.
“We envision SUT owners will take their vehicle off-road, maybe
camping or mountain biking. For easy cleanup once back home, the
SUT features cargo bed drain holes and rubber bed mats, allowing
owners to clean the cargo area with a garden hose,” McCormack
Another feature that will likely come in handy during such
excursions is the SUT’s optional air suspension. In addition to
improving ride quality and increasing ground clearance, the air
suspension adds an auxiliary air outlet in the cargo area,
allowing owners to inflate tires, camping equipment, beach toys or
what have you.
When it comes to performance, the H2 SUT is unmatched. Its
6.0-liter, Vortec 6000 V-8 delivers 325 horsepower at 5200 rpm and
365 lb.-ft. of torque at 4000 rpm. The Vortec 6000 is mounted
longitudinally and mated to a heavy-duty Hydra-Matic 4L65-E
four-speed automatic overdrive transmission with full-time
The four-wheel-drive system is perhaps the most advanced ever
offered on a consumer vehicle. With its five operational modes and
two-speed planetary gearset, the SUT is capable of adapting to
many different road conditions at the touch of a button.
- 4 HI Open for normal, everyday driving on dry
road surfaces at any speeds.
- 4 HI Locked for semi-slippery surfaces like
snow, light sand or wet areas, such as those around a boat
- 4 LO Locked for severe off-pavement use, such
as crawling over large rocks or logs.
- 4 LO Locked + Rear Diff Locked, available
only when the transfer case is in Low Lock position. It permits
locking up the rear differential for optimum slow-speed
capability in climbing over large rocks or up long, steep
- Neutral, obtained by simultaneously pressing
the “4 LO Locked” and “4 HI Open” buttons and holding them down
for 10 seconds. It permits flat-towing the H2 SUT behind another
Adding to the overall sense of
control is a highly developed Bosch four-channel anti-lock
braking/traction control system (ABS/TCS). In addition to
providing optimum control on slippery surfaces, the ABS can detect
and adjust its braking capabilities to rough off-road surfaces,
such as gravel and potholes.
TCS also provides the ability to gain traction through a single
wheel, if necessary. A second mode of the TCS system, “TC2,” used
in conjunction with the transfer case’s selections, provides three
additional operating modes: “4 HI Locked + TC2,” “4 LO Locked +
TC2” and “4 LO Locked + Rear Diff Locked + TC2.” This provides
distinct advantages in different driving conditions, such as loose
sand or gravel in the desert or mud or slippery conditions.
With three transfer case selections, two rear axle differential
selections and two modes provided by the TCS mode switch, the
driver actually has a total of seven driving mode selections,
providing unprecedented versatility to tailor H2 performance to
match driving conditions.
On and off road, SUT drivers will appreciate the independent
torsion bar front suspension, which features 46-mm monotube
gas-charged shock absorbers and a 36-mm front stabilizer bar.
The rear suspension, meanwhile, features a five-link trailing arm,
air springs and a 32-mm stabilizer bar. The spring rate is
variable, from a soft on-road rate, to a transitional rate, to a
stiff off-road rate, which helps prevent bump impact input forces
from entering the vehicle’s body. A coil spring version will be
available in June 2004.
The result is smooth cornering on pavement and a less jarring ride
off road. The standard air suspension also aids the off-road
capability of the SUT. It helps keep the vehicle level under load
and, with its extended ride height feature, makes for a steeper
departure angle when conditions call for it.
