1992 Hummer H1 I Dimensions, Size & Specs

The curb weight of the Hummer H1 I ranges from 3140 kg (6923 lbs) to 3680 kg (8113 lbs), reflecting different engine and equipment options available throughout its production. Its maximum weight, which considers full loading with passengers, cargo, and fuel, spans from 4672 kg (10,305 lbs) up to 4899 kg (10,805 lbs). This substantial weight corresponds to its heavy-duty off-road construction and armored vehicle heritage.

One of the standout features of the Hummer H1 I is its impressive ground clearance of 406 mm (16 inches). This high ride height allows the vehicle to navigate very rough and uneven terrains with ease, making it highly capable in off-road environments. The 406 mm clearance helps it clear obstacles such as rocks, logs, and deep ruts, distinguishing it from most conventional SUVs and trucks.

Fitting the Hummer H1 I into a standard residential garage may be challenging due to its considerable width and height. Standard garage door widths typically range from 2.4 to 2.7 meters (8 to 9 feet), while the H1’s width is approximately 2.16 to 2.2 meters (7.1 to 7.2 feet), so it might barely fit widthwise depending on the garage layout. The height of up to 1.9 meters (6.2 feet) is usually manageable for a normal garage, but the vehicle's overall bulk and turning radius can complicate parking. Owners often require wider or custom garages for easier accommodation.

The Hummer H1 I is heavily derived from the military High Mobility Multipurpose Wheeled Vehicle (HMMWV or Humvee). Compared to earlier military versions, the civilian H1 I retains very similar dimensions — with a slight increase in comfort and trim-specific variations affecting width and height. The civilian model maintains the rugged proportions of the military vehicle, emphasizing width and ground clearance but adding creature comforts and slightly refined styling. Overall, the H1 I preserves the large, boxy, and functional size of its predecessor, setting it apart from typical consumer SUVs.

The Hummer H1 I is larger and bulkier than most conventional off-road SUVs like the Jeep Wrangler or Land Rover Defender. Its length of 4686 mm (184.5 inches) and width over 2150 mm (85 inches) is significantly more expansive than typical SUVs. The exceptional ground clearance of 406 mm (16 inches) also outperforms many competitors, enabling more demanding off-road capability. The H1’s size and weight place it in a unique category, often requiring special consideration for parking and maneuvering, but its rugged military-grade construction is rarely matched by civilian off-road vehicles.

The Hummer H1 I provides seating typically for four passengers, with a utilitarian and spacious interior designed primarily for functionality over luxury. The interior cabin reflects the vehicle's military roots, emphasizing durability and off-road readiness. Though not as plush or refined as modern luxury SUVs, it offers generous headroom and legroom due to its tall, boxy shape. Cargo capacity is substantial, supporting backpacks, off-road gear, and equipment needed for outdoor adventures or heavy-duty use.

The Hummer H1 I's width, ranging from 2159 mm to 2197 mm (85 to 86.5 inches), makes it significantly wider than many passenger vehicles. While this contributes to stability off-road, it can make urban driving and parking more challenging. Navigating narrow streets, tight corners, or compact parking spaces demands greater awareness and experience from the driver. Many owners find the H1 better suited for rural roads, off-road trails, and open areas rather than congested city centers.

Due to its large size, length of 4686 mm (184.5 inches), and significant width, the Hummer H1 I has a relatively large turning radius compared to smaller SUVs. This means that tighter maneuvers, such as U-turns or parking lot navigation, require more space and skill. Nevertheless, the vehicle’s off-road design includes specialized features like portal axles and excellent approach and departure angles which facilitate maneuverability in rough terrain. On paved roads and urban settings, its size can limit agility and ease of movement.

The Hummer H1 I’s size directly contributes to its legendary off-road capabilities. The 406 mm (16 inches) ground clearance allows it to clear large obstacles, while its wide stance (up to 2197 mm or 86.5 inches) provides exceptional stability on uneven surfaces. Its substantial weight, from 3140 kg (6923 lbs) to 3680 kg (8113 lbs), combined with military-grade construction, makes it highly durable in challenging environments. With features like locking differentials and high approach/departure angles, the H1 can traverse rugged landscapes routinely impassable to conventional SUVs.
