Overview & Reviews

A new "Alpha" trim level debuts for the 2008 Hummer H3, giving the pudgy SUV what it needed most -- a serious infusion of power via a 5.3-liter V8. Other notable changes this year include standard side curtain airbags and the availability of a rearview camera.

• Serious off-road ability, smooth ride on pavement, stable handling, simple cabin controls, comfortable seats.

• Tepid performance with inline-5, poor outward visibility for shorter drivers, subpar cargo space, terrible gas mileage.

  Off Road Savant - 2008 Hummer H3
  By James - August 14 - 5:32 am

  Have 5000 hard miles on my supercharged Alpha, driving the worst trails of the eastern slopes of the Sierra Nevada/Owens Valley/Death Valley region, then returning home to a sleepy suburb of Los Angeles where my neighbors shiny clean SUVs never see the dirt. The Hummer H3 rocks! The offroad capabilities are truly amazing, and after beating it up on horrific trails, has not failed to get me home. No overheating while crawling in low range straight up rocky canyons, with AC blasting, and outside temps over 100. Smooth ride over ruts and washboard at high and low speed. Had dealer install the optional skid plate protection, good investment. Nav system needs improvement, no guidance offroad!

  H3 Dream - 2008 Hummer H3
  By CJK - August 12 - 7:45 pm

  I waited a long time and did lots of research before buying the H3. Overall, styling, comfort and American made played key factors. After driving the H3 for two months, I couldnt be more happy. It looks good its fun to drive, and it has more than enough room for a small family. It also feels safe and solid. I ordered some of the factory performance upgrades (intake and exhaust), and it has proved to have more than enough power for todays driving styles. Not a race car, but a great all around SUV.

  Love it - 2008 Hummer H3
  By rob - July 1 - 11:36 pm

  Had a 05 TrailBlazer, loved it. The H3 blows it away. Speed, gas, build quality, and of course character. 4000 miles and not a single problem.

  H3 is the best - pure and simple... - 2008 Hummer H3
  By Brett - March 9 - 3:20 pm

  I owned a 2006 H3 which I loved and sold it for "Toyota reliability". Since I have had 2 FJ Cruisers and one Tundra TRD (all new) and none of them even came close to my H3. So much so I bought a 2008 H3 and couldnt be happier. There are cars for all kinds I guess so to each his own. For me that means H3 and will for a very long time to come.

  Happy H3 owner - 2008 Hummer H3
  By Happy H3 owner - March 3 - 10:20 am

  Pretty happy so far. Tad too early to comment on some things, but bought and drove back 250 miles home and it was more than pleasant on the highway. Ride was smooth and the monsoon sound system was fabulous making it a pleasure to drive home. This will be my wifes car to drive my 2 year old around, so when mamma is happy, everyone is happy. Sorry enthusiasts, this H3 wont see any more mud that what a local pot hole can hold.

  I love my HUMMER - 2008 Hummer H3
  By hummer fan - February 7 - 4:35 pm

  I love my H3. I would not change anything. HUMMER did a great job with the new interior. I also have a 2006 H3. The power of the new 5 cyl is great! Went from 220 in my 06 to 242 in my 08. It is a noticable difference. I highly recommened the new HUMMER H3s

  V-8 just right - 2008 Hummer H3
  By alpha dog - February 4 - 7:40 am

  Upgraded from an 06 I-5 to the new Alpha V-8. Not a huge difference in city driving or offroad but highway driving is improved 100%. Passing and merging much easier and much less annoying downshifting and hunting for the right gear. Big improvement worth the money.

  H3 Alpha - 2008 Hummer H3
  By trader - January 20 - 4:45 pm

  I owned a 2006 H3 for 2 years and put 45,000 miles on it. Off road pkg. It was great off road, but lack power for pulling and acceleration. I have also owned a 2006 H2. Great truck. The new Alpha is what GM needed to build. The V8 is the answer to the underpowered I-5. I purchased this one with the Off road pkg also. I have not had the chance to take it to the mountains yet as I did the other two. I suspect it will outperform the 06 H3 with plenty of power to spare. I have not had the chance to tow my travel trailer yet, but has to be better at it than the 06. The redesigned window and lock placements were neccessary. Acceleration is great. These are trucks, not race cars.

  What a Hummer! - 2008 Hummer H3
  By Larry Leung - January 16 - 6:01 pm

  Just got a new H3 Alpha from Toronto. So far I am extremely pleased with it. Its so solid. Lateral blind spots are minimal with the over-sized side mirrors. I took it to Wal-Mart and Can Tire and it parks with no difficulty, due to its small turning radius and rear vision camera. (A must). Also, with the chrome tubular steps, my kids and 5 wife find it no problem to get on and off it. With the V8 engine, it has enough oomph to get to 80km. I have yet to assess how bad the fuel consumption is (I know..) I love my Hummer H3 Alpha on this day one and I will love it more every day.
