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.

  ALPHA gets an "F" - 2008 Hummer H3
  By ER in Cali - May 8 - 11:19 am

  First off,this car looks awesome! Just sit inside and look really cool, just dont turn it on. Had serious problems from day 3. Ive had this car 6 months and it has been in the service department 4 times. The engine however seem more powerful than the regular H3 (my loaner cars) but Im having a difficult time rating it due to the fact I dont have it most of the time!!! Inside is "space challenged" no room for anything other than the people in it. No backpacks, purses, phones etc... Vision is impaired, be very careful no one is in the crosswalk because you can only see directly in front of you and thats it. In the canyons I find myself leaning to the side so I can see the curves.

  Some design flaws - 2008 Hummer H3
  By Sandie - March 13 - 2:03 pm

  I actually love my H3, but the interior design could offer more comfort and storage. Im 510 yet my arms can not rest on the arm rest of the door panel, its too low. At a stop light, the roof comes down too low in the front, I have to constantly kink my neck down for the light change. There is absolutely no storage space for sunglasses or my purse etc. The exterior design is really cool and powerful looking but just go through one puddle and the dirt and splash from the road goes all the way up the side of the front door and door handles and looks dirty all the time. I am a female in my mid 50s who is tired of driving a van. I am having the time of my life in this vehicle even with the fl

  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.

  H3 Makes this Big Guy Smile! - 2008 Hummer H3
  By garywmd - November 11 - 4:48 pm

  I am a 66" man who has struggled for years trying to find a vehicle that will keep me comfortable during my 1- 1.5 hour commute (each way). A month ago I bought my H3 and I ride in comfort. I was concerned about gas mileage, but it turns out that my old "small" suv only gets 1 mile per gallon more than my H3 (I drive in Los Angeles and it is all stop and go, gas mileage suffers greatly for all vehicles). I find I dont stop as often now because everyone gets out of my way! This is a great vehicle and I ride in comfort!

  H3X ALPHA - 2008 Hummer H3
  By EGK - October 11 - 10:38 am

  This is a loaded 2008 H3X Alpha. My wife shopped all the current updated SUVs - Mazda CX9, Acadia/Enclave, Mountaineer (weve leased five of these in a row). She also decided to look at HUMMER. The dealer let us use a 2007 H3 for a weekend - and she was sold. We also waited to test the H3 Alpha - and that did the trick. The V8 is much smoother, better acceleration and the ride and comfort are excellent. Its still a truck - so dont think it will ride like the other SUVs. But thats part of the reason to buy a HUMMER to begin with. This is one sweet ride. Its too new to assess gas mileage, but again, we know its not a 23MPG vehicle. Put an H3 on your short list!
