Hummer H3: compact SUV, engines and what to know when buying used
The Hummer H3 is a smaller, more straightforward SUV than the H2, produced from 2005 to 2010 and built on the Chevrolet Colorado platform. In this article, we review the engines, trims, driving characteristics, and what to check when buying a used H3 in Lithuania.
The H3 in brief
The H3 was the smallest Hummer model, designed for those who like a distinctive look but don't need the size of the H1 or H2. It shares the same platform as the Chevrolet Colorado and GMC Canyon pickups, so many mechanical parts are from the same GM family.
The vehicle features a full-time four-wheel-drive system with low-range gears (reduction gear) and high ground clearance, so it can handle off-road conditions. The interior isn't very spacious, and the trunk is smaller than that of similarly sized family SUVs.
Trims and engines
Early H3 models came with an inline five-cylinder petrol engine with a capacity of around 3.5 litres, which was later increased to around 3.7 litres. In 2008, the H3 Alpha was introduced with a 5.3-litre V8 engine, producing around 300 hp.
The gearbox is a five-speed manual (with five-cylinder engines) or a four-speed automatic. The H3 always came with four-wheel drive, and the V8 version is the most powerful and thirsty for fuel.
In 2009, the H3T was introduced—a pickup with an open bed. The Hummer brand was discontinued in 2010, making the H3 the last smaller model of this brand.
How the H3 drives
The H3 is built for off-roading, so it feels different on the road compared to typical city SUVs: it's heavier, with more rolling resistance and higher fuel consumption. The five-cylinder engine isn't very economical, and the V8 even less so.
Off-road, it's powerful thanks to its full-time four-wheel drive, differential lock, and large ground clearance. However, due to its size, weight, and wide body, it's not suitable for all buyers — parking and manoeuvring in the city can be awkward.
What to check when buying a used H3
The most important thing is the drivetrain. Test the four-wheel drive and differential lock to see if they engage smoothly, and check for any leaks in the gearbox or transfer case. Make sure the vehicle hasn't been heavily used off-road.
Inspect the underbody and suspension: look for damage, corrosion, or worn-out suspension parts. Evaluate the brakes, steering mechanism, and tyres.
Many H3s in Lithuania were imported from the USA: check the vehicle's history, mileage according to documents, and whether it has been in any accidents. Find out which engine the specific vehicle has, as fuel consumption varies greatly between versions.
