HUMMER is hard to miss with that bold
face and toothy seven-slot grille, a
flat roof and square cabin with narrow
windows that resemble a military bunker.
The original H1 HUMMER, a civilized
version of the military High Mobility
Multipurpose Wheeled Vehicle, or Hum-Vee,
comes from HUMMER's parent company,
AM General. But General Motors has marketing
rights to the HUMMER label and the first
offspring of GM's HUMMER Division is
a junior version of H1 named H2. For
2005 the H2 SUV spawns a four-door pickup
variation tagged as H2 SUT, meaning
the original civilian version of the military Hum-Vee, and it brings awesome capability.
Conformed as a four-door boxy sport-utility wagon or a four-door open-top wagon,
the H1 shows significant enhancements for powertrain and cabin appointments. The
turbo-diesel V8 engine, displacing 6.5 liters, now delivers 205 hp but huge torque
of 440 lb.-ft. at only 1,800 rpm, and it connects to GM's Hydra-Matic 4L80-E electronically
controlled four-speed automatic transmission. Heavy-duty four-wheel-drive (4WD)
equipment goes into every H1 with sophisticated controls to automatically reduce
tire spin on slippery terrain by braking a spinning wheel. In the cavernous four-seat
cabin, H1 gets luxury goods with redesigned seats, fine leather upholstery and
a revamped cockpit and dash design.
of the H2 SUV as a junior version of the H1 HUMMER. It has the boxy body of an
H1 with a flat roof and four-door cabin, but the package is smaller and friendlier
for navigating city streets. H2 rides on a modified version of the chassis of
GM's Chevrolet Tahoe and GMC Yukon wagons, with mechanical components including
a humongous 315-hp 6.0-liter V8 engine borrowed from full-size Chevrolet-GMC trucks.
A broad track and extended wheelbase with brief overhangs and super-sized tires
work to make the H2 exceptionally stable, and a high ground clearance with underbody
skid-plate shielding ensures it can navigate rough off-road terrain.
H2 stocks a Borg-Warner two-speed electronically controlled full-time 4WD system.
The system divides torque from the engine either 40/60 percent front-to-rear for
running at speed with differentials unlocked or 50/50 percent with differentials
locked. Riders in H2's spacious cabin rest on firm bolstered seats and encounter
luxurious accommodations with optional leather upholstery and high-tech audio
and navigation gear. The second-row bench holds up to three adults and an optional
third-row jump seat, which can be folded or removed to expand rear cargo space,
fits a teenager.
HUMMER works as both wagon and truck, which explains the tag of sport-utility
truck, or SUT. It's derived from the H2 SUV with similar powertrain and mechanical
equipment. Where the H2 SUV shows an extended roofline and the boxed rear bay
of a wagon, the H2 SUT differs by lopping off the roof to make way for an abbreviated
truck bed, which is roughly four by three feet in size.
there's more: The back wall of the SUT's cabin also works as a door -- it folds
down and forms a generous extension of the truck box. With the back wall folded
down, there's a flat cargo bay extending six feet to the tailgate for expanded
cargo volume. With the wall raised and window up, the cabin is sealed off from
the rear truck bed. You get a conventional cabin with two bucket seats up front
and a three-person bench in back, followed by the Midgate sealer and the back
unsheltered truck box. Extra equipment ranges from a rooftop light bar and dashboard
DVD navigation system to special packages like the Adventure and Lux series.
