2004 Hummer H1

2004 HUMMER H1: ONE OF A KIND
"Unique." "The original." "The world's premier off-road vehicle." There are many ways to describe the HUMMER H1. Also fitting is "cornerstone," since it's the foundation upon which the HUMMER sales growth is built.

"The H1 is what started it all for HUMMER," said Michael C. DiGiovanni, HUMMER general manager. "It's the vehicle that drew the interest of adventurous consumers across the nation, as well as the interest of GM. It offers superior off-road capabilities rugged enough for the Baja and powerful highway performance."

More power and plenty of poise
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 terrain.

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."
