Overview & Reviews

Coming off a redesign last year, the 2008 GMC Sierra 1500 has only minor changes this year. Satellite radio is now standard equipment and an integrated trailer brake controller is optional. GMC says it will also be offering 22-inch wheels (as a dealer accessory) and a flashier version of the Z71 Off-Road package called the Sierra All Terrain.

• Refined and very quiet ride, pleasing fit and finish inside, seats are comfortable for long drives, comprehensive list of safety equipment.

• Larger turning circle than most rivals, mediocre interior storage and cupholders.

  GM hit it out of the park on this one! I bought the SLT with All Terrain package and its a great combination. Drive the Tundra then buy the GMC.

  Near Perfect - 2008 GMC Sierra 1500
  By OD - December 18 - 12:06 am

  The absolute best truck on the market! Had my Sierra w/ All Terrain package for three weeks and at just under 3k miles, I couldnt be happier. Rides like a luxury car on the highway and an off-roader when needed. All Terrain package runs just under Denali as far as price but maintains more of the off- roader feel. Z71 package w/ 20" chrome wheels, 5.3 liter V8, 2-tone leather seating, & much more. I am getting 20 to 21 mpg on hwy & 17 city! Not bad for a larger V8 that really isnt meant for fuel effiency. Overall, best truck on the market after extensive checking and I couldnt be happier. If you are looking for a real deal with a great feel do not stop short of at least drinving one!

  King of Trucks - 2008 GMC Sierra 1500

  To me this is the best full size pick up there is on the market. It is the perfect combination of power, comfort, elegance, sportiness, not too over the top styling.

  Compare Denali to any other 1/2 ton. - 2008 GMC Sierra 1500
  By bob - March 27 - 11:53 am

  I went into the truck market expecting to buy a Tundra because I have had such good luck with Toyotas.To say that I was pleasantly surprised with the Sierra is an understatement. I priced a loaded SLT with the 6 liter engine and the Denali was about the same price. It was an easy decision to buy the Denali because of the extas like the 6.2 liter motor and six speed tranny to mention a few. This truck will run with the Tundra, rides better, handles better and has a more refined interior. My wife prefers the Denali over her Acura RL, which she loves. My freinds can not believe the power with the engine and tranny combination. Do yourself a favor and test drive a Denali when looking for a new truck!

  GMC Sierra Denali AWD - 2008 GMC Sierra 1500
  By Brent - March 6 - 9:33 pm

  Very impressed with this vehicle. Sold my 175K mile Sierra and due to its excellent performance, Im sold on GMC. The Denali drives and handles great. 18mpg hwy and 16.4 in town. Not bad for a 6.2 ltr V8. My previous 4.8 ltr V8 only beat that by 1mpg! My vehicle came loaded w/options and couldnt pass it up for $38.5K. With gas prices I think they are really having to come down on these things. Very quiet ride on the highway and around town. It does need more storage compartments/center console organizer. I would rather the center console open from the side rather than front. Its somewhat awkward and has a rather flimsy spring hinge.

  Youre missing out... - 2008 GMC Sierra 1500
  By DirtyD - February 24 - 11:50 pm

  I test drove every make of truck and this one got my money. Sharp truck and a real headturner with my Black Z-71. Power is great and off road ability is only topped by a Wrangler (Im an avid Jeeper). Cant say enough about the ride comfort and quiet demeanor, very nice interior. I was looking for a truck, not a Prius or Cadillac. This is the perfect truck.

  Built to last - 2008 GMC Sierra 1500
  By Big Lek - February 3 - 6:20 am

  I never owned a GMC. Everyone i talked to said GMC was just a high priced Chevrolet, now i know the diference. The styling, the ride quality, and low cabin noise are just a couple things that i noticed that were a lot diferent. I also like the fact that this truck is almost all US made. This truck is great.

  Excellent Truck - 2008 GMC Sierra 1500
  By Bryan2008 - January 5 - 8:03 pm

  GMC really did a great job with this truck. I really love the power of the engine and the comfort. I do not drive it much trying to keep those miles off of it. But when I do it is a treat and makes me appreciate life more. It definitely is deserving of much kudos. Thanks again GMC for a really great vehicle.

  Best LuxuryTruck/ SierraDenali AWD 6.2 L - 2008 GMC Sierra 1500
  By X. Joseph - August 13 - 9:56 am

  Just bought this incredible machine. I bought it for the engine even though gas prices are high. It gets decent mileage for its powerhouse 403hp 6.2 liter engine. Best stock V8 horsepower of any brand and you still can chip it to 500hp +. The interior is refined and classy. It looks like my BMW 5 series inside. You can buy a regular fully loaded 4X4 crew and pay the same price. I feel this is the best deal in luxury trucks.approx. 40-45k depending on options. The cadillac escalade has become synonomous with bling bling and hip hop.- it is a little to showy for me. This Denali is not so showy and has a beautiful interior. So far no problems as I am babying it until 1000 miles. Super quality.
