Overview & Reviews

The Chevrolet Avalanche is a distinctive utility vehicle that blends the comfort and passenger capacity of an SUV with the cargo capacity of a long-bed pickup truck. Its unique "midgate" feature allows it to be converted from a five- or six-passenger crew cab pickup with a short cargo box into a two- or three-passenger pickup with a long cargo box. A lockable hard plastic cover keeps the bed contents safe.

Produced for two generations, the Avalanche was based on Chevy's related full-size trucks and SUVs and therefore shared basic underpinnings and powertrains. Though it may command a price premium on the used-car market, the Avalanche also has more to offer than most pure trucks or SUVs. For the shopper in need of a jack-of-all-trades vehicle, either generation of this unusual truck should make for a smart choice.

Used Chevrolet Avalanche Models
The most recent Avalanche is the second-generation model produced from 2007-'13. Sleeker exterior styling, a sharper and more precise driving feel and increased interior refinement were its chief advantages compared to the first-generation model. It was offered in three trim levels: base Avalanche LS, midgrade Avalanche LT and plush Avalanche LTZ. Numerous luxury and technology features were available, including Bose audio, leather upholstery and a rear-seat entertainment system.

Rear-wheel drive by default, this Avalanche was also offered with two four-wheel-drive (4WD) systems -- one with a single-speed transfer case (introduced on the 2010 model) and one with low-range gearing (previously the only option). All models started with a 5.3-liter V8 that initially produced 320 horsepower and 340 pound-feet of torque (310 hp and 335 lb-ft with 4WD). A 6.0-liter V8 with 366 hp and 380 lb-ft of torque was optional from 2007-'09. (Note that rated power on these engines varied slightly through the years, but you shouldn't notice any real-world difference in performance.) Earlier Avalanche models had a four-speed automatic transmission, while a six-speed automatic (which helped improve fuel economy) became standard for 2009.

In reviews of the second-generation Chevrolet Avalanche, we consistently praised its exceptional versatility on account of the adjustable-length bed. From behind the wheel, we found the Avalanche to be comfortable and smooth-riding for such a workhorse, with robust acceleration from either of the proven V8 engines. The towing capacity impressed us at over 8,000 pounds, easily outdoing the car-based Honda Ridgeline, though trailing pure trucks with V8 power. Maneuvering in tight spots was a challenge, however, due to the Avalanche's massive size and considerable blind spots astern. Still, with its updated platform, it was markedly more pleasant to drive than the previous-generation model.

Aside from the powertrain changes noted above, this Avalanche received standard side airbags for 2008, and the LTZ was upgraded for 2009 with standard Bose audio, heated and ventilated front seats and leather upholstery. The final-year 2013 model was technically known as the Black Diamond Avalanche; it was treated to special badging and some additional features as standard.

The first-generation Chevrolet Avalanche was produced on an older platform from 2002-'06, making a name for itself with its innovative midgate, which was largely carried over to the second-generation model. This Avalanche is also very similar to the newer version in terms of passenger space. At its debut, the first-generation model was offered with two- or four-wheel drive and in 1500 (half-ton) or 2500 (3/4-ton) designations. The 1500 came with a 5.3-liter V8 good for 285 hp. The 2500 model had a 340-hp 8.1-liter V8 as well as higher towing and payload capacities. Both engines came standard with a four-speed automatic transmission.

In reviews of the original Chevrolet Avalanche, we gave it high marks for its trick adjustable bed and comfortable seating. Downsides included compromised outward visibility, low-grade interior materials and awkward exterior styling. The latter was partly attributable to the truck's standard-issue gray-color lower body cladding. Chevrolet wisely made it an option starting in 2003.

There were a few other notable changes during this Avalanche's run. The 2003 model year also saw the arrival of standard multistage airbags, optional stability control and a number of new features, while 2004 saw a slight drop in rated power for the 8.1-liter V8 (to 320 hp). Stability control was made standard across the board for 2006.

  This is a great truck - 2005 Chevrolet Avalanche
  By Allmondt - January 13 - 11:29 am

  The most comfotable truck I have had the pleasure of driving. With the power adjustable pedals my 52" wife finds the vehicle easy to drive and handle. When I first bought the truck she said she would not drive it. After riding in it for a few months I have a hard time getting it away from her. The cargo area is small but the cover is very easy to remove and the bed is dry. (even after 20" of snow). This is not a work truck but great for pulling a trailer and transporting a family. The 4 wheel drive options are nice. I used both automatic 4WD and full time 4WD druing our 20" snow storm. I went where ever I wanted. 14 mpg city about 17 mpg highway

  Love it! - 2005 Chevrolet Avalanche
  By Dave - January 1 - 1:16 pm

  I have over 52,000 miles on my 2002 Z71 4x4 Avalanche, I also tow a 6,000 lb tralier on camping trips. Never have had a problem since Ive owned it, not even a burned out bulb. I change the oil & filter every 3,000 miles. Chevy got this one right! Best SUV/truck on the road, rides like my Town car. Off road is awesome too.

  Avalanche "the biz - nizz" - 2005 Chevrolet Avalanche
  By madspeakerman - December 31 - 2:32 pm

  functionability, biggest trunk in the business, converts into a truck when needed & still has that soft car ride. comfort, mines loaded, a friend of mine has the H2 which has the same steering wheel controls, dash and stereo, door controls (seat heaters and foot adjustments) but you just dont sit at the same angle as the avalanche or suburban H2 more upright and stiff. In the nine monthes ive owned my 04 ive put 25k on it from the beach to the snow. "had the tranny replaced at 20k, warranty covered, bought extended 48 mon. 80k". Around town & local L.A. highways its like youre to only be in this urban cruiser, feeling safe due to size and able to see over traffic, AWSOME! & 14.3mpg avg.

  Dont judge book by the cover - 2005 Chevrolet Avalanche
  By bshef - December 28 - 2:45 am

  I had every intention of buying a 1500 silverado crew cab. However, I took the Avalanche for a test drive and immediately fell in love with its ride, power, comfort and most of all..."versatility". Im not the type of guy who will spend $4k on exterior mods for "others" to look at.....I deal strictly with functionality and reliability. The Avalanche not only fit the bill for everything I wanted in a truck......but it also gave me a "built- in" bedliner, a bedcover, extra storage and lots of other bonuses that most consumers end up spending lots on after they buy a new truck. This truck also has great brakes and plenty of power.

  Dennys Truck - 2005 Chevrolet Avalanche
  By Dennys Truck - December 24 - 2:34 pm

  Ive had my truck for 3 months and it has been the best purchased vehicle Ive made thus far. It does not ride like a truck. It is very confortable to drive and ride in. I consider this to be one of my better investments.

  Avalanche of show and might - 2005 Chevrolet Avalanche
  By don - December 16 - 6:44 am

  Indeed a great show of power and looks. It is rugged yet with refined maneuverability and interior design. My wife finds the masculinity and yet get the utility one finds in a kitchen (table?)! I feel the thundering power when it revs up to 110/mph or humping mountains in NH. It is like an Abrams tank that every car in your path, that is in the fast lane, move to the right of the highway when you come to their tail. The gas mileage is awful though but still manageable compared to others of its class.

  Love my Chevy - 2004 Chevrolet Avalanche
  By Bush - December 14 - 5:42 pm

  I never thought Id like the smaller bed but not once has it ever been an issue. I love the locking rear tailgate and hard cover. I go camping in the truck and simply lay down the back seat and put my pillow behind the front seats and feet out in the bed. Its secure and comfortable. I recommend the Avalanche to anyone looking for something different without giving up their truck. Believe it or not the locking boxes on the side are pretty cool too. I go boating and I also trailer motorcycles to the trails and its a good place to store my straps and hitch. The lock too so my stuff is safe. Plenty of room for the family and plenty of power to pull my 4,500 pound boat through the hills.
