What's New

General Motors has introduced a few changes to the 2008 Hummer H3. A new trim version named ""Alpha"" was introduced this year. Apart from the new trim version, a rearview camera and standard side-curtain airbags are new to the H3 lineup.


The 2008 Hummer H3 has inherited all the design characteristics from its predecessor, the H2, which includes the massive wheel flares, brand signature styling cues, industrial grille, and armored-style windows. All these design characteristics make the Hummer H3 more appealing to customers.

Based on a 111.9-inch wheelbase, the H3 measures 188.1 inches long with rear-tire carriers, 74.7 inches wide, and 73.2 inches tall, and weighs a massive 5000 pounds. Customers can also get additional exterior features straight from the factory, such as chrome fuel doors; a distinctive spare-tire cover, brush guard, wheels, and center-cap cover; a body-colored grille; and bright roof crossbows.


The interior of the 2008 Hummer H3 somehow does not gel with its rugged exterior characteristics. The build quality and design of the interior is average. General Motors should have used some quality materials to give the interior an upscale look.

The H3 has a fair list of comfort and convenience features such as air-conditioning; front, rear, and cargo floor mats; a cargo-area light; a passenger vanity mirror; front reading lights; and an electro-chromatic inside rearview mirror. The H3 is equipped with an AM/FM in-dash single CD player stereo, six speakers, and an XM satellite radio. The entertainment system also features an adjustable speed-sensitive volume control. A hands-free phone with OnStar telecommunications service is standard in all 2008 Hummer H3 models.

The interior of the car has ample storage space to stash small items while travelling. Front and rear cup holders, front seatback storage, and storage space in the front console are some of the convenient storage options provided.

Performance & Handling

Powered by a strong 5.3-liter, V-8 engine generating 300 horsepower and 320 lb-ft of torque, the 2008 Hummer H3 has abundant power to take on rugged terrain and city roads. A generous ground clearance, optional 33-inch offroad tires, and standard skid plates give the car numerous capabilities on rugged terrain.

The 4:1 low gearing allows the 2008 Hummer H3 to coast down steep trails without using the brakes. The V-8 engine allows the H3 to go from zero to 60 mph in just eight seconds. The five-cylinder engine, generating 242 horsepower and 242 lb-ft of torque, seems inadequate to power this heavy behemoth.


The 2008 Hummer H3 receives high ratings in passenger safety and crash tests conducted by the National Highway Traffic Safety Administration (NHTSA). The H3 has a generous list of safety features, such as four-wheel ABS, emergency brake assist, an engine immobilizer, stability and traction control, and electronic brake force distribution.

It also boasts front height-adjustable headrests, two front and rear headrests, front seatbelt pretensioners, ventilated front disc/solid rear disc brakes, a remote anti-theft alarm system, front and rear head airbags, a post-collision safety system, front fog driving lights, and many other safety features.
