The Hummer H2 (GMT 840), produced from 2002 to 2009, measures 4820 mm (189.8 inches) in length and 2063 mm (81.2 inches) in width. The vehicle's height ranges between 1993 mm (78.5 inches) and 2080 mm (81.9 inches), depending on the specific configuration and suspension setup.

The curb weight of the Hummer H2 (GMT 840) varies between 2901 kg (6,395 lbs) and 3017 kg (6,650 lbs), reflecting different trim levels and optional equipment. Its maximum gross vehicle weight rating (GVWR) is approximately 3900 to 3901 kg (8,598 to 8,600 lbs), accommodating the weight of passengers, cargo, and additional gear safely.

In terms of cargo capacity, the Hummer H2 offers 1132 to 1133 liters (39.95 to 39.98 cubic feet) of luggage space with all seats in place, which is quite spacious for an SUV of its size. When the rear seats are folded down, the cargo volume expands significantly to 2451 liters (86.5 cubic feet), enabling the transport of larger or bulkier items.

The Hummer H2 has a ride height or ground clearance of 255 to 257 mm (10.0 to 10.1 inches). This elevated ground clearance enhances its off-road capabilities by allowing it to clear obstacles such as rocks, ruts, and uneven terrain more easily than many other SUVs. It enables the vehicle to traverse rough landscapes without damaging the undercarriage.

Yes, the Hummer H2 commonly comes equipped with 17-inch rims paired with 315/70 R17 tires. These relatively large, wide tires improve traction and stability on various terrains, which is essential for an off-road SUV. The tire size balances on-road comfort and off-road ruggedness, optimizing the vehicle’s performance in diverse conditions.

Given its substantial dimensions, the Hummer H2 does pose challenges when fitting into a standard residential garage. Typical garage door widths are about 2438 mm (96 inches) wide, and ceiling heights around 2134 mm (84 inches). With the H2’s width of 2063 mm (81.2 inches) and height reaching up to 2080 mm (81.9 inches), the vehicle will fit in terms of width but leaves little clearance on the sides and vertically. Owners might need to exercise caution or consider garages with taller ceilings and wider doors to comfortably accommodate the H2.

Compared to the original Hummer H1, the H2 is generally more compact and designed with more urban and family use in mind. The H1 is larger in terms of length, width, and is heavier due to its purely military-grade off-road build. While the H1 measures about 4589 mm (180.7 inches) in length and 2235 mm (88 inches) in width, the H2 is a bit wider but shorter overall. The H2 prioritizes a balance between rugged off-road capability and everyday usability, making it more accommodating for personal transportation compared to the utilitarian H1.

The Hummer H2 stands out in the large SUV and off-road segment with its bold, aggressive styling and substantial size. While many large SUVs range from 4800 mm to 5200 mm (189 to 204 inches) in length, the H2’s 4820 mm (189.8 inches) length is comparable to vehicles like the Chevrolet Tahoe or Ford Expedition. However, the H2’s wider body (2063 mm or 81.2 inches) and higher ride height lend it superior off-road capabilities compared to typical full-size family SUVs, positioning it as a vehicle that blends luxury with extreme off-road readiness.

The 2003 Hummer H2 (GMT 840) is an off-road vehicle and full-size SUV known for its ruggedness, imposing presence, and advanced off-road features. It was designed to appeal to consumers who wanted the military-inspired look and capability of the original Hummer but in a more family-friendly and luxurious format. The H2 excels in off-road conditions thanks to high ground clearance, durable tires, and a sturdy suspension system. It is also equipped with spacious interiors and modern amenities, making it suitable for both rough terrains and urban environments.

During its production from 2002 to 2009, the Hummer H2 was primarily equipped with a robust V8 engine. Early models featured a 6.0-liter V8, which was later upgraded to a 6.2-liter V8 engine offering improved performance and torque, crucial for both on-road power and off-road capability. The H2 includes features like four-wheel drive, locking differentials, and heavy-duty suspension to tackle challenging terrains. Its large size and powerful drivetrain also contribute to its substantial curb weight, demanding careful driving and increased fuel consumption.
