Hummer H3 Specs, Engines & Dimensions (2005–2013)

Hummer H3 Engines and Transmissions

Every Hummer H3 engine here is a gasoline unit driving all four wheels, so the real choice is displacement and transmission. Examples include 3.5 MT and 3.7 MT with a manual, or 3.7 AT with an automatic. The manual suits drivers who want direct control; the automatic eases traffic and low-speed crawling.

Hummer H3 Trims and Equipment

Hummer H3 trim levels sit on top of the mechanical version rather than replacing it: the 3.7 MT, for instance, appears in Base form. Equipment differences typically cover upholstery, climate control, audio and convenience features, while the engine, gearbox and drivetrain stay exactly as the technical version describes.
