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 The Quadrasteer four-wheel steering option has been dropped, and the optional camper-style mirrors have been replaced by a folding and extending design with a built-in convex spotter glass.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.

  Confused by others - 2006 GMC Sierra 1500
  By T.Davis - October 27 - 3:53 am

  I have owned toyotas and nissans and never get the mpg they or the reviews say. 2 to 3 miles less. With GMs I have seemed to get 3 to 5 miles better than reviews. Thats why I say confused by others. Just got 22.6 combination downtown Nashville, TN interstate,country roads. Just bought this truck and probably will keep it for a long time. Guess my driving habits suit GM products better. This truck has 5.3, 323 gears,2wd, locking rearend and HD towing.Confort scored 8 cause stiff HD suspension (I guess). Build quality an 8 cause of interior parts a little weak. Reliability was 9 mainly cause of my past history with GMs. Havent owned this one long enough to tell. Thats my 2 cents worth.

  Best truck Ive ever owned - 2006 GMC Sierra 1500
  By rick spriggs - June 10 - 2:33 pm

  It has 4 wheel steering and it is great when im towing my trailers or I need to park in a tight spot. The truck has all the power I need and it gets about 18-19 mpg, 16 mpg when towing. The seats are like sitting in a lazyboy, very comfortable. I love my truck.

  Lees Review - 2006 GMC Sierra 1500

  Replaced a 2006 Ridgeline for towing. Not much to say but excellent! While ride is not as good as Ridgeline, it has more room, power, and beauty. [Beauty is in the eye of the beholder]The leather interior is excellent and comfortable.

  Test drove Tundra and others. Came back to GMC because of superior deal and value, including room, comfort, etc. I highly recommend this truck to anyone looking for something that is solid, reliable, and the best possible value on the market. Thanks GM, Great Job!

  I love my truck! - 2006 GMC Sierra 1500
  By NathanTexas - April 9 - 1:33 am

  I bought this truck because my 06 Silverado would not pull my boat (4.8L). This truck is great, lots of power, great fuel mileage, and a ride like a Cadillac.

  I love my Sierra - 2006 GMC Sierra 1500
  By W. Oates - November 13 - 6:13 am

  I traded my bullet proof Chevy for this GMC and I havent been disappointed. I Use my truck as a daily driver and as a work vehicle. Im in construction and my Sierra sees a lot of heavy use for a 1500 and does the work of a 2500 handily. I dont baby this truck at all and it rarely gets a bath. I love the roomy interior and power this truck gives me. ITS a V6!! Its zippy and maneuverable. Love the gas mileage and power was a trade off I thought Id have to give on a little but Im not let down by the 4.3 V6.

  New Year New Truck/Great Truck Great Yr - 2006 GMC Sierra 1500
  By Darkcloud - October 10 - 7:40 am

  I picked up this truck on New Years Day. Have already driven over 250 miles. Power heated leather seats are very comfortable. Interior is luxjurious and instruments and gauges are well positioned, very readible for day and well illuminated for night driving. XM Satellite radio with Bose sound system is incredible comnbination that gives exceptional listening experience. Beautiful and functional interior styling. 4X4 has great handling on highway and very nimble in city traffic. Wind noise is almost imperceptable when driving at highway speeds. Park feature of power exterior passenger mirror makes parallel parking a full size truck as easy as parking an automobile. This is a well build truck.

  Gas mileage is very good, truck is very comfortable to drive. I have very positive comments from others about the overall appearance. The heated mirrors are very helpful.
