Hummer H2: Redesign, Specs, Range, Speed

Everything You Need to Know About the Hummer H2

The Hummer H2 is a luxury SUV and SUT, best known for its masculine body and excellent off-road capability. It’s among the heaviest SUVs of its time and was inspired by the military Humvee (H1). The Hummer H2 was produced by General Motors and sold under the Hummer brand between 2002 and 2009.  Unlike H1, which was exactly derived from the military vehicle, H2 was built on a modified version of General Motors’ full-size truck platforms. This guide covers specs, redesign, interior, and performance to help you make an informed decision.

Hummer H2 Specs 

Interior of the Hummer H2

The Hummer H2 interior has more of an early-2000s American SUV feel. The Hummer H2 prioritizes durability, presence, and utility first, with a touch of luxury. It features a heavy-duty vehicle interior, unlike many SUVs that focus on softer interior materials.

Hummer H2 Fuel Capacity, Range & Speed 

The gas tank size of the Hummer H2 is one of its standout features, reflecting its large and heavy-duty design. The 2003 to 2009 Hummer H2 models feature a gas tank capacity of 32 US gallons (approximately 121 liters). The Hummer H2 has nearly twice the fuel capacity of most SUVs, which typically hold around 80 liters. 

Another important detail is that when your fuel light comes on, the tank is not actually empty. Like most vehicles, the vehicle has a built-in reserve, so you usually won’t be able to fill the tank to the full 121 liters unless it’s completely drained. 

Despite the large tank, the driving range is unimpressive; it delivers only 4-6 kilometers per liter. For reference, the 2009 Hummer H2 fuel economy remains within this range, making it one of the least fuel-efficient SUVs in its class. However, the Hummer H2 accelerates from 0–100 km/h in approximately 9–11 seconds, with a top speed of around 160 km/h.

Hummer H2 Performance 

Its performance is not what people expect when they hear “V8 SUV”. It is not built for speed or sharp handling. It is designed to move a massive, heavy machine across any terrain with authority. The H2 comes with two main engines. Earlier models used a 6.0-liter V8 engine producing around 316 to 325 horsepower and about 360 to 365 lb-ft of torque. Despite its big engine numbers, the Hummer H2 is extremely heavy, weighing around 6,400 to 6,600 pounds. Acceleration is not fast due to the heavy weight. The H2 excels in torque delivery and traction. The V8 engine provides strong low-end torque, which is exactly what you need for off-road driving. There were also discussions around an H2 hybrid Hummer concept, but it never reached full-scale production.

Hummer H2 Exhaust 

Hummer H2 comes with a traditional V8 engine exhaust designed for durability and compliance. It includes 

• Exhaust manifolds
• Catalytic converters
• Mid-pipe section
• Muffler
• Single or dual rear exit (depending on model)

The Hummer H2 has a deep tone because of the V8, but the sound is controlled and muted.
