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.

  Best Truck for the Money - 2008 GMC Sierra 1500
  By Matt - October 17 - 6:30 am

  I have been looking at buying a new truck for a while and the Sierra Denali is by far the best bang for the buck, that is if you can afford it. The truck has the best ride and handling of any truck I have ever driven. Gas mileage is not to great, so far I have average 15 mpg in the city and I got up to 22 mpg on the highway, but that is not to bad considering you have 403 HP on tap. The truck has excellent fit and finish and the exhaust note is very nice. If you pay sticker for this truck you will be paying way too much, I managed the get the 2WD model with the upgraded 20" chrome wheels for $35,900 (retailed for a little over 42). Bottom line, a great truck for the money.

  Love This Truck - 2008 GMC Sierra 1500
  By Dwight - September 20 - 9:40 am

  This truck replaced a V6 GMC I had for 17yrs. The power of the V8 is wonderful for a 4.8L and half the price of the 5.3L The truck handles great. It sits higher than my old truck so is a little harder to get into (Im 6ft) so I installed nerf bars. Everything about the truck is high quality. Lots of cab storage, cup holders. The stereo is quite good for factory installed.

  Best of the Breed - 2008 GMC Sierra 1500
  By sknabt - April 7 - 10:46 am

  I decided to replace my SUV with a full-size truck. Choice came down to an 08 Sierra SLT vs. an 07 Tundra Limited (08 Tundra priced way out of my budget) because Ive always bought Japanese. Tundra has nice powertrain but falls short in every other category, especially its bloated price. GMC SLTs greatest selling point is its luxury grade interior. Tundra is very weak here. GMCs shift at any speed automatic 4x4 is far better than Tundras crude hi/lo 4x4. GMC has better crash test scores than the Tundra. This is the 1st full-size truck Ive ever owned but driving it is actually a joy. Parking is a learning experience but the parking assist makes it doable even for a newbie like myself.

  So Far So Good - 2008 GMC Sierra 1500
  By kitch - September 28 - 4:00 am

  Just over 1 week of ownership and I can say I am very pleased with the vehicle. Traded in my Titan LE for this. Interior fit, finish and textures is by far the best Ive seen on any truck. Flip up seats in the rear are nice and a necessity (Tundra I test drove didnt have that). Bose stereo is good and Nav seems easy to operate. Not quite as fun to drive as my Titan was, but still decent. Nice rumble from the stock exhaust. 6 speed tranny is smoooooth. Nice and quiet at 60mph. The AWD is a nice feature to have.

  Powerful and Comfortable - 2008 GMC Sierra 1500
  By spud90 - June 24 - 12:46 pm

  I have never owned a truck before, but I will be moving my son to college and am planning some large home renovations. I bought this truck because dealers are making incredible deals on full-size trucks. A 2.5 ton vehicle with a 315hp engine that gets 15mpg around town is not bad in my opinion. Mine is a 4x2 because I am always on asphalt and it rarely snows in SE Virginia. One tip: Stabilitrak comes with traction control. So consider this option with a 2WD if you want a lower sticker and really dont want/need the extra maintenance and fuel comsumption of a 4WD. This vehicle handles well and is smooth and quiet. It reminds me of a 1977 Lincoln Town Car, only it handles much better.

  This is one amazing truck! - 2008 GMC Sierra 1500
  By Denjhe - May 24 - 12:26 am

  I have had my Black/black 08 Sierra Denali for about 2 months now. Amazing power. Amazing comfort.. Amazing headturner. A beautiful ride in every way. The MPG of 11-12 in the city is a bit of a nuisance but if you spend $42K for a truck you better not whine about the cost of fuel!! If you have the means you should buy this truck.

  I expected much, got more. - 2008 GMC Sierra 1500
  By icelander - November 14 - 10:13 am

  After reading reviews about almost all possible kinds of trucks I decided on my Denali. Have had it for several days and this truck delivers. Interior is down to smallest detail without any fault, my truck actually looks better than the LandCruiser 200 having classical and delicate finish. Exterior is also great, kind a smart how low the truck looks giving the feeling of real street machine. It of course performs as a truck, no mistake there, but its a looker. PS. Did I mention its screamingly powerful?

  Great Truck - 2008 GMC Sierra 1500
  By Drewgold - September 27 - 10:40 pm

  Ive only had this truck for a month and all I want to do is drive it. It rides and drives much better than my 05 did. (though I was happy with that truck as well) The controls are well laid out and easy to reach. There is planty of interrior storage. As for all you cry babies about gas mileage, what do you expect from a 5000lb truck with a 315hp V8? I am pretty much getting what the sticker claims. (14/19) If you are that concerned about gas mileage I recomend the Malibu. If you want a great truck then buy a Sierra.
