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.

  Ive just recently purchased my 2003 Chevy Avalanche Z71. It is a very awesome vehicle that has loads of room and versatility. I would recommend it to anyone who does not need a pickup all the time.

  Only truck I will own. - 2006 Chevrolet Avalanche
  By Doc1038 - November 18 - 5:32 pm

  This is my second Avalanche I have owned. I will NEVER own another truck except the Av. Very Stylish, Eye catching, versatile. Used for camping, tailgating, towing, moving large items, and much more. My original was a 2002 which I thought was great, and the 2006 is even better. I totalled my 2002 in an accident which I hit in, and realized in any car and many trucks, I would not have made it out alive. VERY SAFE!!! Fuel economy is not bad for the size of the truck, but it should be expected with its size and capacity.

  Great Vehicle - 2002 Chevrolet Avalanche
  By Phisp - November 17 - 12:30 pm

  Bought this vehicle because my wife loved it, I did not like the way it looked and the fact it did not have a real full size bed. I now love it the Z71 package is a must I can haul all my fire wood, take my wife and kids camping while towing the boat do some off roading and take it surf fishing easily.. No problems to speak of, GM hit a home run with the Avalanche. My buddies Nissan Titan feels about half as strong as my Avalanche and he has been through 2 rears and 5 long term visits to the dealer for service , Considering a Titan? buy the Avalanche.

  Avalanche - 2006 Chevrolet Avalanche
  By CPasq - November 15 - 1:27 am

  Versitile, rides like a large car, but still able to handle non paved roads with relative ease. Good power with the 5.3L v8. Hwy mileage is closer to 19.5mpg on level roads at 65-70mph. Easy to convert to pickup with the midgate. Love this truck.

  Happy Owner - 2003 Chevrolet Avalanche
  By Happy Owner - November 10 - 12:24 pm

  My Z66 Avalanche is the best truck I have ever owned, and I have had several over the years. I added a Gibson exhaust, K&N air filter and the computer adjustments. The truck runs awesome. The only problem I have had in 28,000 miles is the steering shaft, since it was replaced, nothing, not even brakes. It tows my trailer with two big bikes in it like nothing is even there. I recently added 20" wheels and I get lots of comments on the "green monster." The truck is comfortable for five adults and the ride is more like a car than a truck, very smooth. I use the fold down feature often, mostly leaving the rear window in place and folding the lower section (for ladders etc.). Excellent!!!

  Style and comfort - 2005 Chevrolet Avalanche
  By Kingpole - November 10 - 2:51 am

  I was more than happy to be able to upgrade my Chevy vehicle from a Tracker (2WD convertible) which was fun to drive-like a golf cart, to the Avalanche. WOW! I have had it for 3 months now and enjoy every second driving it. Power, style, and smooth ride. I should mention that the stock stereo/CD system works just fine. I have Bose in the house and thought Id be spoiled and would need the Bose quality in the truck-NAH. It rocks just fine.

  One Awesome Truck - 2003 Chevrolet Avalanche
  By Anthony F. Dugo Jr. - October 31 - 11:41 pm

  I have had my Avalanche(Z-66) for 1 year now. I bought it used & I can tell you this is one awesome Chevy truck. Its bright red & a head turner. I get compliments all the time. It has everything but the kitchen sink in it. .It has a very comfortable ride for a truck . No other competitor can touch this baby! ! Even with the two wheel drive, she glides through the snow like Santa on his sleigh. Its a heavy truck, and tracks through the snow & mud with ease. . Although she likes her fuel, I did not but this vehicle for economy,but since installing a K&N filter and switching to premeium fuel, she runs like a dream. Went from 14.5 to 17.5 mpg. Thanks Chevy for one awesome truck! !

  Great Vehicle - 2004 Chevrolet Avalanche
  By ckellerman - October 27 - 10:00 am

  As a long time P/U owner, this adds luxury while keeping some P/U utility. The leather, sound, programables, etc. all make the Av. comfortable and fun to operate.
