After complaints of an underpowered engine became deafening, the 2008 Hummer H3 added a new 5.3-liter V8 to its lineup. The new H3 Alpha gets 300 hp and 320 lb-ft of torque, and its dimensions have been slightly revised to accommodate the larger engine from the Silverado. It also purportedly is cleaner than many pickup engines. The regular 5-cylinder, 3.5-liter engine remains, now putting out 242 hp. Both engines come with either a 5-speed manual or 4-speed Hydramatic, and the Alpha has taller gears.
The 2008 H3 features 4WD with low-range gearing, 9 inches of ground clearance, and skid plates, and is designed specifically for off-roading. Traction control and rack-and-pinion steering have been revised this year, and all models come with ABS brakes, stability control, a tire monitor, and dual front airbags. Side curtain airbags have also been added in the Alpha for 2008. Base models feature a full power setup, cruise control, and CD player, and as you move up through Luxury and H3x, you add heated leather seats, power front seats, and a 6-CD changer. The H3x adds styling notes, such as a chrome fuel door and body-colored grille.
Rear seats split-fold 60/40 and fold down to open up the small cargo area to 56 cubic feet. Tie-downs are included, but a cargo cover is extra. You can also add a trailer hitch to tow up to 4,500 pounds in the regular H3 and 6,000 pounds in the Alpha V8. The rear-mounted spare tire, which hampered visibility, has been moved under the bed. Options include a sunroof and rearview camera. The extra V8 power has increased the 2008 H3's rugged off-roading performance, and the smaller overall size of the H3 somewhat improves city maneuverability, but highway driving still lacks power, and the rear seats are still cramped.
What owners say
"Overall, Hummer H3 owners love the vehicle's solid build, comfort, and off-road capabilities, describing it as reliable and fun to drive. Many appreciate the spacious interior and sturdy design, making it great for outdoor adventures. However, some dislike the underpowered engine and poor fuel economy, with a few mentioning difficulties in visibility due to the thin windows."
The Hummer H3 is a great utilitarian vehicle with incredible style and strength. The all-time 4WD handles beautifully on and off the road. You sit up high on the road and have good visibility. The rear cargo area has ample space to store your gear for any type of adventure. I highly recommend this for the outdoor enthusiast who also likes to look classy driving downtown.
March 7, 2014I just think the H3 Hummer combines Lucy with the option to off road with this vehicle. It’s got a very smooth ride and it’s easy to get parts and service. It’s also a beautiful SUV. It has lots of room and when you fold down the back seats you have extra cargo space. Even with the rear seats up the cargo space is very spacious. Gets actually good gas mileage. I like the engine size and when you have snow and ice it goes into 4 Wheel drive easily. It can drive right around people who are actually stuck in ice and snow. It’s great for towing also.
July 27, 2023Great Vehicle. It has power, speed, comfort and style all rolled up in one. Love my Hummer H3.

June 7, 2023The Hummer H3 is a solid and comfortable vehicle. The car was priced appropriately, but this particular vehicle had a mechanical problem in the front end. The Hummer H3 is hard to compare to other vehicles. It is rather unique due to its heritage.
July 19, 2021Great GM mechanics. Reliable and capable. Not a Colorado as the chassis was considerably changed. It looks better than other GM cars of the era,
February 13, 2020I love this car! I drove it for about a month and it is the most solid car ever! It has the best handling, good speed and whoever said you need small cars to go fast is proved wrong by the hummer. This is a car that is worth it!!!
October 28, 2008It`s a nice car, and really do it`s job, in any where and any situation, buy it and enjoy it. You will Love It. It`s not to expensive. Maybe the fancy people will love the H2 but this one it`s Rough and still is Gorgeus and Classy.
July 8, 2008I would definitely recommend this car to anyone looking for something in its class. I have driven jeeps and loved them too, but compared to the sturdiness that the H3 had and the luxurious feel, I didn't like them near as much. The V8 alpha version is definitely worth the extra money as the v6 only gives 239 hp and its curb weight is some monstrous number. We took this car camping a few times and my favorite part of the H3 is that it is unstoppable in the dirt. Off-roading in it was a blast!
October 18, 2012I like the color (bright orange) very much and the fact that it is a 5 speed. It needed the passenger seat repaired when purchased. The Hummer handles very well. Overall, it is a comfortable, fun vehicle to drive. Gas mileage is around 16 mpg and 14 around town
June 1, 2010Great SUV. So easy to drive. Very comfotable and spacious.Could use slightly more power on hills with the 5 cyl.6 cyl would make a huge difference, however the H3 is a very nice SUV. Thank you GM. A quality SUV.
