Visually, the most dramatic improvement for 2004 is the new interior,
raising H1 to a more refined, more upscale plateau.
“Although H1 still has all of the capabilities that made
it a huge hit with our service men and women, it’s really
a new kind of luxury vehicle. In fact, many H1 owners purchase this
vehicle in lieu of an exotic vacation or home addition. As such,
we felt it was imperative to raise the level of the vehicle’s
refinement—bringing it more in line with today’s luxury
vehicles,” said Jon Albert, HUMMER interior designer.
A higher level of refinement can be found from the instrument panel
to the cargo area, and from door panel to door panel. The result
is a more luxurious, more inviting, more accommodating and more
New, high-quality leather seats that feature a more pronounced
bucket design for enhanced support and greater comfort and new seatbacks
that enhance forward visibility for rear passengers are just the
beginning of H1’s new interior improvements.
“The aniline leather on the seat inserts, the new color themes,
all of H1’s standard features—as well as H1’s
interior roominess—result in a vehicle that has all the comforts
of an upscale home,” Albert added.
That interior roominess is actually enhanced for 2004, thanks to
redesigned overhead and center consoles.
“We looked at the interior design of the previous H1 and
realized that we could repackage some elements to create a vehicle
that feels even larger on the inside,” Albert explained. “For
example, by using an integrated six-disc CD changer in place of
the 12-disc changer, we were able to give the upper area of the
center console a cleaner, sleeker look, while also providing a more
integrated look for the glove box.”
A quieter cabin
Also improved for 2004 are H1’s interior noise levels, thanks
to additional insulation and a refined powertrain. The result is
a cabin environment that is perceptibly quieter to the human ear.
More power and plenty of poise
There’s also more power for 2004, thanks to a retuning of
the 6.5L, turbo-diesel V-8 engine. As a result of the improvement,
the 6500 now delivers 205 horsepower at 3400 rpm and an impressive
440 lb.-ft. of torque at 1800 rpm. That’s 10 horsepower and
10 lb.-ft. 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.
