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.

  2 1/2 yr review - 2003 Chevrolet Avalanche
  By JC - July 25 - 6:43 pm

  Well I bought it because of the bed conversion capability. It seemed like a good idea, but in actuality more of a hassle to convert to full bed. The bed panels are a chore to remove and store. If you plan on using the full bed a lot, then get a regular pickup! No issues with the engine, but thats where it ends. In 2.5 years Ive been to the dealer for new rotors and pads all around at 5,000 miles, steering shaft replacement, Bose radio replacement, rear window replacement, faded cladding, center mount brake light replacment, regrease steering shaft, failed rear end, and failed transmission. All fortunately covered under warranty except the tranny. I baby the thing. Ive never towed or gone off road.

  496 rocks - 2005 Chevrolet Avalanche
  By krazy - July 3 - 10:34 pm

  The real thing. A Chevy big block with even more cubes than its ancestors. Needed more than a standard cab truck for new family addition, and couldnt stand the idea of not having an 8 bed for occasional use. This fits the bill just right. A very versatile truck with all the comfort and power of an old full size vehicle. We found the midgate to be a breeze to operate. A real cool truck on a nice day with the midgate down, 4 windows and sunroof open. Will add a performance program, synthetic oil, and performance air filter to wake up the 8.1. 12 to 13 mpg on a variety of driving. The 7 month pregnant wife loves it too.

  The TruckUV - 2004 Chevrolet Avalanche
  By DMAN - June 27 - 2:00 am

  I have had a great time with my New Alvalanche. It took me a month just to get use to all the nice gagets and features. I still get a kick out of driving down the highway and making my side mirriors fold in at the same time. The conversion is always a thing of beauty. I have been asked several times to perform the change and I always deliver on the request. When I am behind the wheel I feel large and in charge. The wheel span on this vehicle in incredible. Got Alvalanche Will Travel!

  Great Multi-Purpose Luxury Vehicle - 2005 Chevrolet Avalanche
  By curtiss Grant - June 26 - 8:54 am

  A great vehicle for a mix of luxury and utility type environments. It accomodates and impresses passagers with comfort and style, while providing area to haul almost any type of cargo. The interior provides room, comfort and quietness to conduct business in person or on the phone. The cargo area can be changed and adapted with ease and on-the-fly to provide security with lockable closed- in space or one can change the setup to enable hauling of large long items. All of this with one vehicle, saves me money and a tremendous amount of time and effort.

  Chevy 2500 - 2005 Chevrolet Avalanche
  By Alain - June 13 - 6:54 pm

  This truck drives like a Lamborghini - plenty of power and excellent handling, far better than the 1500 series. After one year and over 10,000 miles, the truck runs better than new and is free of mechanical problems. I love it!

  After one year - 2005 Chevrolet Avalanche
  By John Rogers - June 11 - 12:30 pm

  My Avalanche is the first full size truck Ive ever owned after 25 years of driving. I bought it for its versatility, towing capacity and styling. The truck has not disappointed after 16,000 miles. Gas mileage in congested Dallas, with a lot of stop and go traffic everywhere, has averaged a little over 15 MPG. I like the ride and handling of the vehicle and its really very comfortable as a daily driver. The only build quality problems Ive had are with the body side molding which developed adhesive bubbles that required replacement of all door moldings after one year. I would never buy a just a pick-up. The versatility of a luxury vehicle with the ability to tow and haul is great!

  Almost there...but still just a Chevy - 2005 Chevrolet Avalanche
  By SlashDG91 - May 11 - 9:12 pm

  Ive used every inch of this vehicle and it can handle any type of cargo. One of the best options for self employed construction, plumbing, etc. Z66 impressed early but as time goes on it needs far too much dealer work. Comes with almost anything you could need for short, mid, or long drives. Comfortable seats both front and rear but leather is very cheap and wears quickly. Stereo is well below the quality that should be expected for the price of this vehicle. Eats oil like nothing Ive ever driven. Gas mileage is horrible...and I was prepared for bad mpg, but not single digit bad. Tires become worn easily for some reason. Any truck is as good and 10K+ less with fewer overall hassle
