Major changes included: A 3.7 liter Vortec 5-cylinder engine comes standard in generation one of Hummer's smallest SUV. It emphasizes off-road utility, being able to ford 24 inches of water going 5 mph granted by its 9 inches of ground clearance. A Chrome Package option is available, which accents the side-view mirrors, door handles, and wheels. The base model is rudimentary, while the H3X boasts street-inspired styling, such as sharp angles and chrome accents outlining the body's edges. The H3 is offered in an Alpha trim in 2008, which is set apart by a 5.3 liter V8 outputting 300 horsepower and 320 ft-lbs of torque.
