2008 Hummer H3 Trims and Specs

There are no major changes to the 2008 Hummer H3 Base model, a mid-sized four-wheel drive SUV packing a 3.7-liter, 242-hp DOHC I5 engine and choice of 5-speed manual or 4-speed automatic transmission. The four-wheel drive features four settings ranging from high to low gear ranges and a locking center differential. Nine inches of ground clearance, skid plates, 16-inch wheels with all-terrain tires, and a truck-like suspension make this SUV a tough and true off-roader. ABS brakes, traction and stability control, dual front airbags, electronic brake assist, foglights, automatic headlights, daytime running lights, dusk-sensing headlights, and a tire monitor are standard safety features.

The 2008 H3 Base seats four in two rows, with split-folding rear seats that expand the 29 cubic foot cargo area to 56 cubic feet. A roof rack and tie-downs are standard, and a trailer hitch can be added. A rooftop lightbar is also optional. Standard equipment includes full power features, cruise control, a CD player, intermittent wipers, temperature display and a compass, OnStar, keyless entry, and cupholders in front and back. Options available separately or in packages include heated leather seats, power front seats, satellite radio, a sunroof, a CD changer, chrome accents, and an off-road package that beefs up the suspension, tires, and adds a locking rear differential.

Hummers were designed for off-roading, and the 2008 Hummer H3 Adventure, though the smallest Hummer on the market, is the SUV best equipped for this activity. Equipped with a 3.5-liter, 242-hp DOHC I5 that gets 242 lb-ft of torque, and a choice of standard 5-speed manual or 4-speed automatic, the Adventure comes with four-wheel drive with four high and low range settings. Unlike the other H3s, it comes standard with a 4:1 electronic transfer case, larger off-road tires, and a locking rear differential. This is in addition to the skid plates and nine inches of ground clearance that pave the way for the 2008 H3 Adventure to tackle unpaved byways.

4-wheel disc and ABS brakes, traction and stability control, a tire monitor, automatic headlights, foglights, an auto-dimming rearview mirror, and dual front airbags are also include. Side curtain head airbags are new this year. Inside the four-seater, you get cruise control, full power features, intermittent front and rear wipers, OnStar, a 6-CD changer with seven speakers, security system, compass and temp display, front power outlets, and keyless entry. The cargo area holds up to 56 cubic feet, and a standard roof rack adds more space. A trailer hitch can be added to tow 4500 pounds. Other options include a sunroof, power front seats, navigation system, and chrome accents. The Adventure is basically an option package itself that can be combined with the Luxury package.

Basically a trim package, the 2008 Hummer H3 Luxury adds upscale features to the already well-equipped base model. In addition to power features, cruise control, intermittent front and rear wipers, a 6-CD player with seven Monsoon speakers, a temperature display and compass, and Onstar, the Luxury package offers heated leather seats and 8-way power front seats. Other Luxury features include a cargo cover, in addition to the tie-downs in the 29 cubic foot cargo area, expandable to 56 cubic feet once the rear seats are folded down. Chrome features prominently on the exterior of the 2008 H3 Luxury.

Engine power in the full-time 4WD H3 Luxury comes from a 3.5-liter, 242-hp DOHC I5 and choice of 5-speed manual or 4-speed auto tran. A front independent and rear live axle suspension rides on 16-inch chrome wheels with all-terrain tires, and safety equipment includes traction and stability control, 4-wheel disc and ABS brakes, dual front airbags, automatic headlights, foglights, dusk-sensing headlights, and a tire monitor.

The 2008 Hummer H3X adds a lot more luxury features to the more manageable four-wheel drive SUV. It shares the same 242-hp, 3.5-liter DOHC I5 that puts out 242 lb-ft of torque, and comes with either a 5-speed manual or 4-speed automatic, but adds larger 18-inch alloy wheels with all-terrain tires. The full-time 4WD also features low-range gearing with four settings, a locking center differential, and is joined with skid plates, 4-wheel ABS brakes, traction and stability control, and dual front airbags for safety and confident handling. Automatic headlights, dusk-sensing headlights, an auto-dimming rearview mirror, tire monitor, and foglights are also standard. The 2008 H3X is not rated for crash test safety.

Inside, the 2006 H3X adds heated leather seats with 8-way power adjustments up front. Also included are a 6-CD changer and 7-speaker sound system, satellite radio, and leather trim. This is in addition to full power features, intermittent front and rear wipers, cruise control, a compass and temperature display, OnStar, remote entry, power outlets and cupholders, and 60/40 split-folding rear seats. The cargo area expands to 56 cubic feet and features tie-downs and a light. A roof rack is also standard. A new option this year is a rearview camera, joining such available features as a sunroof, navigation system, and a trailer hitch for towing up to 4500 pounds.

Brand new this year is the high-testosterone 2008 Hummer H3 Alpha, with a stronger 5.3-liter, 300-hp V8 that produces 320 lb-ft of torque. The new engine boosts two ratings to 6000 pounds. Full-time four-wheel drive is accompanied by a locking center differential, revised rack and pinion steering, four high and low range gearing settings, traction and stability control, 4-wheel ABS brakes, electronic brakeforce distribution, and 16-inch wheels with all-terrain tires. Other safety equipment includes dual front and side curtain airbags, a tire monitor, automatic headlights, an auto-dimming rearview mirror, and foglights. The truck suspension (front independent and rear live axle), skid plates, and nine inches of ground clearance add to the off-road capability.

Much like the H3X, the 2008 H3 Alpha has heated leather seats, a 6-CD changer, 8-way power front seats, satellite radio, full power features, keyless entry, intermittent front and rear wipers, and OnStar. It doesn't have the standard tubular running boards, but does come with a roof rack. A lightbar is optional. The Alpha adds a universal remote to the standard features and a chrome grille. The cargo area expand from 29 to 56 cubic feet and comes with tie-down. A trailer hitch is optional. Other options include a rearview camera, sunroof, navigation system, a body-colored grille, and an off-road suspension package, which includes a stiffer suspension, off-road tires, and a locking rear differential.
