Used 2006 Hummer H3 Base

The 2006 Hummer H3 Base 4-Door SUV brings the bold, rugged styling of the Hummer brand into a somewhat more manageable midsize form. Underneath its tough exterior lies a vehicle built more for off-road capability than slick highway performance or luxury sedan refinement, but it delivers a distinctive presence and capability that stands out. Under the hood of the H3 Base sits a 3.5-litre inline-five-cylinder engine producing around 220 horsepower and 225 lb-ft of torque. This engine is paired with either a five-speed manual or an optional four-speed automatic transmission, and full-time four-wheel drive is standard. The vehicle features strong off-road hardware: skid plates, a low-range transfer case, a locking rear differential (on certain packages), and about 9.1 inches of ground clearance—making it more than just cosmetic tough. Despite this, the weight of the vehicle means highway acceleration is modest, and it isn't as nimble in everyday driving as typical SUVs of its era. Inside, the H3 seats five people, with a reasonably comfortable front row and a usable rear bench, though space and visibility may feel somewhat constrained compared to more family-oriented SUVs. Cargo space is about 29.5 cubic feet with the rear seats up, growing to around 55 cubic feet with them folded—again, respectable but not class-leading. The interior styling reflects its rugged purpose: durable materials, straightforward controls, and the kind of large switches and grab handles you might expect if you’re going off the beaten path. Comfort features such as dual-zone climate control or a premium stereo may be available in higher option levels, but base models keep it simple. On pavement, the H3 rides solidly but with certain compromises. Its off-road suspension and considerable mass contribute to a ride that’s firm and more SUV-truck-like than refined sedan-like. Body roll is present, and acceleration requires some forethought when passing or merging. That said, drivers often say that when the H3 is in its element—trail, rock, steep incline—it shines: you feel confident the hardware can handle serious terrain, which is rare in many midsize SUVs.
