Hummer H3 Specs and Generations

The Hummer H3 brought military-inspired styling into a more manageable mid-size package, pairing serious off-road hardware with everyday usability. Here is what matters most when you compare the versions offered.

Hummer H3 Generations

Hummer H3 generations are represented here by the First Generation, available in two body styles: a five-door SUV and a double-cab pickup. Begin by choosing the body that fits your use — enclosed cargo space or an open bed — then compare the individual versions offered within that generation.

Hummer H3 Specifications

Hummer H3 specifications differ by generation and version, so treat any single figure as belonging to one configuration rather than the whole model. Powertrains across the represented range are gasoline. Equipment depends largely on the version, while body style influences dimensions, cargo access and daily practicality.
