2003 HUMMER H1

Dec. 01, 2002 By ORC STAFF

As General Motors continues to grow the HUMMER brand, the foundation upon which that growth is built, the HUMMER H1, remains rock-solid. The original HUMMER, H1 is a one-of-a-kind vehicle, the world?s premier off-road vehicle, rugged enough for Baja, refined enough for the country club.

"The H1 is what started it all," said Michael C. DiGiovanni, HUMMER marketing director. "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 and terrific highway performance as well."

New features for 2002

HUMMER H1 has some content and feature upgrades for the 2002 model year, its last year alone in the HUMMER stable as the H2 prepares for its 2003 introduction.

HUMMER H1 models come in two distinct choices: 4-Door Wagon and 4-Door Open Top. For 2002, the models have a higher TBR (Torque-Biasing Ratio) Differential to improve mobility, performance and reduce the amount of wheelspin required to lock.

For 2002, H1 offers new two-piece, 17-inch forged aluminum wheels shod by new Goodyear MT/R tires. The vehicle also sports new LED side marker lights and a new H1 badge.

Inside the H1, a reshaped and improved console creates more knee room for the right front passenger, while revised seatbelts and retractors help to better protect occupants. There?s also a new steering wheel center hub with more sharply defined lettering, and a new driver?s side express-down window.

A commanding presence?and a commanding powertrain

The HUMMER H1 is world-renowned for its intimidating presence. It has an impressive width of 86.5 inches and an overall length of 184.5 inches. The truck?s low center of gravity, long wheelbase (130 inches) and 72-inch track make it extremely stable in varied road conditions and surfaces. Its 16-inch vertical ground clearance is almost double that of any other 4x4. Approach and departure angles of 72 degrees and 37.5 degrees respectively, enable ascent and descent of steep grades without vertical interference.

The H1 is powered by a 6.5-liter, 195-horsepower turbodiesel engine manufactured by AM General, which generates 430 lb-ft of torque. Its near-midship location provides excellent weight distribution. GM?s 4L80-E electronically controlled four-speed automatic transmission allows smooth transition of power for improved mobility off-road. Over time, it 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 springs. The front suspension incorporates a large stabilizer bar to improve handling and reduce sway when turning. 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. H1?s Central Tire Inflation System (CTIS) enables the customer to adjust tire pressure on the move and adapt to varying terrain. When the H1?s tires are deflated, the size of the tire footprint is increased, providing better traction in snow, loose sand and mud.
