The Hummer H2 is an all-American icon on four wheels. You can't miss it with that bold design and its sheer size.
The Hummer H2 was built to command attention and tackle tough terrain. Introduced in 2002, it blends rugged 4x4 performance with luxury SUV comforts. The H2’s production ran until 2009, and even today it compares uniquely with large SUVs like the Range Rover or older Toyota Land Cruiser models, though it trades efficiency for impact. Key features include the growling V8 engine bringing the power, room for five as standard (with an optional small third row), and a reputation for conquering rough conditions. On the used market, drivers love the H2 for its spacious cabin, confident driving position and its sheer gravitas on the road. However, it’s important to consider costs and practicality compared to UK rivals.
Massive road presence Comfortable, spacious interior Serious off-road ability
High running costs Large size limits parking Firm ride and limited efficiencyYes it's big – and it's solid too – but beyond that, the Hummer H2 features essential safety features such as ABS, traction control and front airbags. Later models added side airbags and stability control into the mix too. Those sturdy truck-based foundations brings a reassuring sense of security, though the vehicle may lack some of the advanced systems found in newer SUVs.
Most Hummer H2s come with a 6.0-litre V8 petrol engine in early models, which got bumped up to a 6.2-litre V8 in later years. All versions feature automatic transmission and four-wheel drive. Both engines lean into strength more than efficiency, which is useful if you're towing or heading off-road.
Standard H2 technology typically includes climate control, electric seats and a CD stereo. Later versions add luxuries such as heated seats, a sunroof and parking sensors. Infotainment is a little basic by modern standards, but comfort features are generous for its era.
The H2 is known for being a bit of a gas guzzler. Expect around 10–15 mpg, depending on driving style, terrain and engine version. Insurance and road tax are also on the higher side, which is worth considering if you're in for the long haul with this car.
Look for a complete service history, especially regular oil changes and attention to suspension or electrical components. Given its size, you might want to get underneath it and check for any body or undercarriage damage. A professional inspection from The AA Vehicle Inspection service can also provide a bit of extra peace of mind.
The H2 has a reputation for robust mechanicals and straightforward engineering, but running costs (fuel, tyres, parts) can stack up higher than the average. Owners have pointed to consistent maintenance as key for keeping the Hummer ticking over nicely. Reliability matches other large US-built SUVs, but it doesn’t quite match the best-in-class for UK roads.
