(from GM Press Release) No
matter the size or configuration, a vehicle adorned with the HUMMER name
must deliver the best-in-class capabilities that have made the brand the
standard against which other off-road vehicles are measured.
That's certainly the case with the dynamic H3T, a midsize truck that
infuses all of HUMMER's military-derived DNA into an efficient, refined
package and carves a new niche in the midsize truck market.
HUMMER introduced the ruggedly refined H3T concept vehicle at the 2004
Greater Los Angeles Auto Show, providing a glimpse at a growing family
of expressive, versatile vehicles.
"The H3T concept expresses a vision of the potential of future HUMMER
vehicles, targeted at enthusiasts who desire the HUMMER image and
capability, but in a smaller, non-SUV configuration," said Clay Dean,
design director for small trucks and HUMMER. "It also provides a visual
clue to the evolution of HUMMER's design."
Innovative features abound in the H3T: The pickup box incorporates
side-access doors, along with drop-down assist steps that also double as
weather-tight storage compartments. The H3T's unique tailgate forms an
unbroken load surface when down, contributing to the H3T's versatility.
There's also a large, power-operated folding canvas sunroof and
drop-down rear window that combine to offer an open-air driving
There wouldn't be a HUMMER badge on the H3T if it didn't have the
capability to dive into twisty terrain that would leave lesser 4x4s
spinning their wheels. Its wheels-at-the-corners stance, along with
34-inch-tall tires and 11.5 inches of ground clearance, gives the H3T a
51-degree approach angle and a 50-degree departure angle - critical
measures on HUMMER's internal "off-road performance metric" of
And while the H3T delivers on the promise of its familial looks, it does
so with a youthful, masculine flair.
"Regardless if you're a man or woman, it brings out a rebellious side to
you that harks back to younger days," said Dean. "It's an irreverent
vehicle - a bad boy in a black tie."
Riding on a 118.6-inch wheelbase and measuring 74.5 inches wide, the H3T
embodies the classic HUMMER proportions - wide stance, low roofline, and
wheels at the corners - that have made the H1 and H2 instantly
recognizable around the world. And like the H1 truck, the H3T
incorporates the cab and bed in a single structure for enhanced strength
and an integrated appearance.
"This is a different size vehicle, but it's a HUMMER throughout," said
Dean. "The cab configuration is personal and the smaller size makes the
H3T more manageable and less intimidating to some drivers than larger
vehicles. The smaller size also gives the H3T a more sporting and
dynamic driving sensation."
To complement the H3T's solid structure
with a "go anywhere, do anything" aesthetic, GM and Nike designers
collaborated on several key aspects of the vehicle's design.
The H3T's tires evolved from discussions between GM Design and Nike
Design regarding the question of off-road performance footwear
influencing off-road performance tires. The result is the innovative ACG
TA tire, which addresses multiple traction environments with sand
paddles, traction pads and multiple durometers of rubber defined by
different-color breakouts - much like the design of Nike's ACG trail and
hiking shoes. BFGoodrich partnered to engineer and build the striking,
Nike's influence on the interior includes the use of its Sphere material
on the H3T's seats. The lightweight material, used by Nike in
specialized clothing, can cool or warm the body without mechanical
means. It also conveys a technical aesthetic that looks perfectly at
home in the H3T. The seats also are enhanced by Nike Epic backpacks,
which are integrated into seat-back clamshells and released with elastic
"The Nike collaboration is unique and exciting," said Dean. "It allowed
us to share ideas and thoughts, while comparing our design process with
a world leader in design innovation. The experience has enhanced the
whole H3T project."
HUMMER design language
The H3T's classic proportions reflect its
off-road ability, but also symbolize HUMMER's expressive styling - an
American design that says as much about driver freedom as HUMMER's
"It's a minimalist approach that conveys purpose," said Dean. "The H3T
represents the continual approach to HUMMER's overall design theme -
simple in appearance yet strong to the touch. From parts like the door
handles to the dashboard details, the H3T looks and feels as if it's
been milled from a solid billet of steel or aluminum."
That purposeful appearance is delineated from the HUMMER H1's military
"We evolved the HUMMER design language with the H2," said Dean. "But
we're continuing that vision and progressing the brand."
The H3T's purposefully premium interior environment includes a rugged
shifter handle that folds completely forward and military-inspired
toggle switches for various controls. An altimeter, compass and
inclinometer also are mounted on the dashboard.
The technical leather and Nike-designed Sphere seat fabric continue to
support the athletic, performance theme of the H3T, as do the chamois,
petrol and paprika orange interior colors.
"It's not necessarily a luxury environment in the classic sense - it's a
new type of luxury," said Dave Lyon, interior design director for
body-on-frame vehicles. "The expression of quality through the use of
specific materials conveys a premium look without the use of traditional
luxury appointments like wood or leather."
The same goes for the H3T's exterior, which features high-tech, yet
durable, LED headlamps and taillamps, an integrated winch and tow hooks,
as well as front and rear skid plates that are stamped out of aluminum
and joined with side "rock sliders." There also are control arm and rear
axle skid plates, along with a carbon fiber skid plate/belly pan, which
protects the vehicle when off the road and aids aerodynamic efficiency
on the highway.
A brush guard is integrated with the front skid plate and the taillamps
have integrated lens protectors. Driving/marker lamps are built into the
The exterior colors, Petrol Blue Metallic and Satin Titanium Alloy, fuel
the H3T's theme of a rugged vehicle with serious attitude. The
forward-opening hood is aided by trigger-operated latches, which
integrate into the trademark HUMMER hood louvers. An exposed radiator is
another classic HUMMER styling cue and a camera mounted on the hood can
be used to record off-road excursions in DVD format.
At the rear, the tailgate features exposed hinges (with integrated gas
struts) and cantilevers to provide an unbroken load platform for the
bed. The bed is more than 4 feet wide and has very small fender
"The H3T supposes a new realm of rugged, yet premium choices for drivers
who find larger vehicles don't fit their needs," said Lyon. "With the
H3T, a whole new group of driving enthusiasts benefits from the
relevance of HUMMER's unflappable capability. There simply is nothing
like it in the midsize truck market."
The H3T is built on a modified GM midsize
truck platform, including the coil-over front and rear suspensions. Fox
remote-reservoir shocks are used for the ultimate in off-road dampening.
An automatic transfer case locks the vehicle into four-wheel drive when
The locking front and rear axles on the H3T are borrowed from full-size
GM trucks. Braking is accomplished with four-wheel discs from Alcon. The
15-inch-diameter rotors are clamped down upon with Baer six-piston
calipers in the front and four-piston calipers in the rear.
Nineteen-inch wheels are mounted at all corners.
A 350-horsepower, turbocharged version of GM's new Vortec 3500 inline
five-cylinder engine powers the H3T, and it's backed by the heavy-duty
Hydra-Matic 4L65-E electronically controlled four-speed transmission.
The turbocharged five-cylinder produces more power than most
six-cylinder engines, but is more compact. The engine also makes 350
lb.-ft. of torque, which helps the H3T tackle steep terrain with ease.
Fuel-saving variable valve timing technology, which is available on some
of GM's four-, five- and six-cylinder engines, boosts the
five-cylinder's efficiency by varying valve timing, lift and duration.
It also improves emissions and overall performance.
Although currently a concept vehicle, the H3T was built with
production-type components, including chassis and suspension components
that were leveraged from existing GM truck architectures.
"Everything about the H3T says HUMMER," said Dean. "The package may be a
little smaller, but the personality, functionality and, most
importantly, the off-road superiority is all there."
