2003 HUMMER H1 Review

A large, heavy, commanding vehicle with outstanding off-road abilities.

Reviewed by Automotive on

Overview

The 2003 Hummer H1 is one of the most noticeable vehicles on the road. This big vehicle is both loved and hated. Those who love it boast of its off-road ability and its attention-getting style. Those who hate it complain of its thirsty engine, its road hogging size, its low power, and its high price. If you’re looking for a family vehicle or something to get you around the suburbs, and you really want a Hummer, go for the smaller H2. The H1 is better suited for off-road enthusiasts or those who live in more wide-open spaces.

The Range

Body Styles: Hummer
Engines: 6.5-liter turbo-diesel V-8
Transmissions: four-speed adaptive automatic
Models: Hummer H1 Open Top, Hummer H1 Wagon

What's New

The 2003 Hummer H1 receives a few minor changes in 2003. The Eaton E-locker is now available for the rear axle. The front end receives a new brush guard. Inside the vehicle is a new audio faceplate, as well as a brand new 12-disc in-dash CD player.

Exterior

The 2003 Hummer H1 has a style all its own. It is large and blocky with an aggressive front fascia sporting round, almost glaring headlights. It is a versatile vehicle and available as an Open Top version, or a Wagon with a sealed top. The overall length is a massive 184.5 inches with a 130-inch wheelbase, and a 72-inch track. Two fuel tanks are attached to it, one holding 25 gallons of diesel, and the other holding 17 gallons. It is equipped with 17-inch run-flat tires. The H1 has a 16-inch ground clearance, giving it a much higher stance than that of a standard SUV. This translates to great off-road capabilities, allowing it to practically leap over boulders. For example, it can ride through 30-inches of water without a problem.

Interior

The 2003 Hummer H1 is not altogether impressive. For such a large vehicle, there isn’t that much passenger or cargo space. Four seats are available. Between the seats is a large tunnel that houses the transmission and the drivetrain. This makes the interior quite noisy and separates the passengers from one another. Even though the exterior has a military appearance, there are several creature comforts. New to this year’s model is a redesigned audio faceplate and a 12-disc in-dash CD player. Optional is a high-quality Monsoon audio system for those who have the money. Other standard features include cloth bucket front seats, rear ventilation ducts, remote power door locks, power windows and mirrors, heated mirrors, one-touch power windows, cruise control, seatback storage, cup holders, front and rear air-conditioning, front and rear reading lights, Monsoon Premium brand speakers, two sub woofers, and more.

Performance & Handling

The 2003 Hummer H1 comes equipped with a 6.5-liter, turbo-diesel, V-8 engine based on a GM design. The engine produces 195 horsepower and 430 lb-ft of torque. The big torque better facilitates off-roading and heavy towing. The V-8 is paired with a four-speed adaptive transmission controlling a permanently engaged four-wheel drive. The engine has a slew of low-end locking differentials. With the differentials properly engaged, it can climb hills as steep as 60 degrees. Even if the public hates it in theory, it is a joy to drive off-road. It can handle pretty much anything nature can throw at it. Large bumps, huge potholes, daunting hills; it handles them with ease. The ride is very noisy because the drive train is very close to the occupants. The H1 also has trouble going down tiny streets.

Safety

The 2003 Hummer H1 is classed as a heavyweight vehicle. Vehicles within this class do not require airbags or other safety equipment. It takes advantage of that by offering little to nothing.
