The 2008 Hummer H2 hits the ground with a familiar look but more power under the hood and welcome refinement inside. Highlights include a new 393-horsepower V8, a completely redesigned instrument panel, new seats -- including a full third-row seat for two passengers -- revised door trim panels and controls, and new comfort, entertainment and safety features.

Inspired by the massive military-derived Hummer H1 off-road ground pounder, the full-size Hummer H2 sport-utility vehicle debuted five years ago as the go-to choice for the "look at me" crowd. Constructed of various bits and pieces from GM's full-size truck and SUV parts bin, its rough-around-the-edges attitude was as much a part of its charm as the H2's all-conquering off-road capability.
