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.

  Cant go wrong with the Avalanche - 2005 Chevrolet Avalanche
  By chevy like a rock - May 26 - 6:33 pm

  I have had it for 3 weeks now, and I drive 60 miles each way to work. Great ride. Gas mileage is not bad for the highway. I have been averaging 19-21 mpg. @ 80mph. We tow our camper with it, and it handles it with no problems. Very comfortable back seat areafor our 3 kids.

  Our new Chevy Avalanche is the best vehicle we have ever owned. The smooth ride and comfort of the interior are awesome. XM Radio is a surprisingly nice feature.

  I love this vehicle. So smooth, and rides like youre on clouds. The Bose stereo system is excellent. I cant believe Im doing 65 mph. It feels like it 25mph, thats how smooth it is. I love this vehicle. If I trade it in later on, it will be for another one.

  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

  A versatile truck - 2004 Chevrolet Avalanche
  By Avy Owner - May 11 - 3:48 pm

  Many have suggested replacing the removable glass with a rear power window that retracts into the midgate. I like the existing design. By lowering the midgate, while leaving the glass and tonneau in place, I get extra load space AND protection from the elements. I love the adjustablity of the drivers seat, especially the lumbar support. Its the most comfortable seat I own. Ive owned trucks with both the 5.7 and 5.3L engines. GM claims the 5.3 has more power and better economy. That has not been my experience. The 5.7 always felt like it had more grunt and got better mileage. This truck needs both. I average 14-15 mpg. On the whole, though, a great truck.

  A Pickup with Class - 2005 Chevrolet Avalanche
  By Texcowboy9 - May 1 - 1:09 pm

  First we thought about buying an Escalade, then we looked at both the Avalanche and the Escalade side by side. Not any difference in the profile. The front end was different as was the interior. For saving the extra money and being practical we went with the Avalance on a Smart buy. We have been on one trip (1200 miles) and this is a very comfortable and luxurious truck. We averaged 19 mpg on the trip, the power is very good along with the fuel economy. Six passengers are no problem. We took my daughters dog with us one way to leave with a friend, the back seat folded down, the rear bulkhead folded down and the kennel sat with the door open in the cargo area facing forward. Worked great

  Better than a Caddy for less - 2005 Chevrolet Avalanche
  By justy - April 29 - 7:05 am

  The most complete vehicle I have owned in years. Will trade for a new one if this one ever dies. Engine does well above expectations. Interior is like sitting in my own private entertainment center.

  Ok, but many problems - 2005 Chevrolet Avalanche
  By Shawn Martin - April 28 - 4:22 pm

  The truck is neat in its design, but this makes it very, very large. Performance is poor (sloppy brakes, sloppy steering, handling and acceleration). I had mine back to the dealer six times within the first 9 months at which point I sold it to buy a different brand. Great concept, but GM needs to do a lot of work on overall build quality, interior design quality and performance (needs a little sport).
