Overview & Reviews

For 2006, there's a new "VortecMAX" performance group that includes a 345-hp 6.0-liter V8, a heavy-duty tow package and a stronger rear axle; thusly equipped, the half-ton Sierra is on more equal footing with Nissan's Titan and the Hemi-equipped Dodge Ram. The Quadrasteer four-wheel steering option has been dropped, and the optional camper-style mirrors have been replaced by a folding and extending design with a built-in convex spotter glass. Other changes on the GMC truck include slightly updated front-end styling and minor adjustments to trim levels and body configurations.

• Roomy extended and crew cab models, variety of V8 engine options, innovative features, slick hybrid-electric option.

• Lags behind the competition in refinement, spotty fit and finish, low-grade interior materials.

  First GMC Truck - 2006 GMC Sierra 1500
  By Dr. Joseph White - October 23 - 1:16 pm

  1st GMC truck that I have ever owned. I have always been a FORD man until two weeks ago. This GMC leaves all the FORD trucks I have ever owned in the dust. I love everything about my new GMC truck, especially the ride and POWERRRRRR. This truck is like riding in a luxury car with a sports car engine.

  Wonderful truck - 2006 GMC Sierra 1500
  By ericfromhouston - April 10 - 12:53 am

  This truck has been great. The room is fantastic and the ride is a dream. My wife loves the way she can drive this truck and not feel intimidated. I love the power and the feel of the way the truck handles in all situations. GMC has defined the term "Texas - Cadillac."

  Nice Rig - 2006 GMC Sierra 1500
  By Robo M. - January 10 - 7:53 am

  Truck is very smooth. My wife has never driven one of my trucks by choice, but she wants to drive this one.I have owned Ford, Dodge. This is my first Z-71 Sierra. All the toys included except for a universal garage door opener. The engine is powerful and fast. Smooth acceleration fools you as to you actual speed. The MPG is approximately 3 miles per gallon more than my 2001 dodge truck. I live in hilly areas and the 4X4 truck averages 15 MPG. With 2 growing boys the Crew Cab gives them more than enough room in the back seat, grown adults no longer mind riding in the back seat of my truck. This is a cant miss vehicle! If you are looking for a new truck test drive this one!!

  Very Nice Truck - 2006 GMC Sierra 1500
  By gkway - November 14 - 4:36 pm

  Bought this truck after testing every full size on the market. I liked the F- 150 but nobody was willing to be half way reasonable. Toyota thinks to highly of the Tundra, and Dodge is a major gas hog. I am already getting over 17 mpg in the city and 21 mpg on the highway, and that is with less than 2000 miles on it! The seats are very comfortable on long trips, and everything seems to be well laid out. Their is so little road noise it is incredible! I really like this truck!

  VERY GOOD TRUCK - 2006 GMC Sierra 1500
  By BRIAN - May 21 - 6:56 am

  Enjoy the GMC truck very much. Rides great and can see out very good. My wife loves the truck and the way it handles. Comfort is first class, and the crew cab is wonderful. Our god children enjoy the crew cab very much. No problems so far. Anyone looking for a crew cab truck so look at the GMC.

  Solid Truck - 2006 GMC Sierra 1500
  By Bob Hunt - March 5 - 8:03 pm

  Lots of research online, couple of test drives and a superb track record with my last GM product led me to this truck. Solid truck with great power and resonable fuel economy that has a cabin as comfortable and quiet as any large sedan. Guages and controls are thoughtfully laid out. Driving visibility is excellent. Responsive handling and braking. Look forward to keeping this truck for at least the next 10 years. Id recommend the Sierra to anyone who wants a great looking and reliable truck for a good price.

  Great Truck - 2006 GMC Sierra 1500
  By P.S. - Texas - December 27 - 6:13 pm

  I purchased this truck on a whim and it has been the best thing I have ever done. The truck is fantastic, it meets all my expectations and more. It is an absolute pleasure to drive around town or on long trips. I would certainly continue to by GMC in the future.

  My First GMC Truck - 2006 GMC Sierra 1500
  By roadturtle - October 5 - 12:03 pm

  I have owned Toyota, Nissan, Chevrolet, and Ford trucks. I chose this GMC truck because I could reach into the bed without having to climb into the truck bed as you have to on Fords. I wanted the full four doors, a small, but powerful V-8 5.3 L. It get equal gas mileage to a Nissan Frontier yet I get a real full size truck for the same price. The seats are very comfortable. I can get into the cab of the truck without stepping onto steps, or hitting my head because the door opening is small as on the Toyotas. It turns sharp, rides nice, handles well, and it came with dual climate zones. My wife loves that. Its the little things that also count such as, fuel filler on drivers side, fog lamps

  Joy to own, my first GMC truck - 2006 GMC Sierra 1500
  By JosefM - July 19 - 2:13 am

  Ive owned this truck for only a month, but it is a welcome surprise. Power and ride is far better than expected. Gas mileage is better than most, in this vehicle class. Towing and hauling is impressive. Ive carried a couple loads of wood through rough terrain (4Low works well) with ease! Would recommend to anyone wanting a powerful and functional truck to buy one today.

  Great Truck!! - 2006 GMC Sierra 1500
  By Mike C. - April 21 - 3:16 pm

  My 1st GMC Truck. I test drove a Dodge, Ford, and Silverado. This truck runs excellent. Rides nice, Lots of room and it is fun to drive. Towing is exceptional, I have hauled 1/2 ton of sand with no problem. Gas mileage is good for as heavy as the vehicle is. Clear view of all vehicle traffic while driving on to all intersections and from yield signs.
