With 13,000 pounds of towing power, the 2008 GMC Sierra 2500HD outperforms all other pickups in its segment. And it does so while looking good and feeling good, according to critics and owners. The three-quarter ton, full-size heavy-duty pickup gets few changes after last year's refresh, but does add standard XM satellite radio to all trims and a power driver's seat in all Regular Cab sizes.
A prominent front grille and logo, flanked by large jeweled headlights announces the Sierra 2500HD's arrival in your rearview mirror. The pickup comes in Work Truck, SLE, and SLT trims, each available in rear-wheel or two types of all-wheel drive -- part-time or automatic. Low-range gearing and an optional Z71 off-road suspension allow you to take this monster off the beaten path. There are also three cab sizes. Two-door Regular seats two or three, the Extended cab has two rows and reverse-hinged rear doors, and the Crew cab features two rows for six with four regular-sized doors. Choose from two different bed sizes (6.6 and 8 feet) and two different engines. The standard powertrain, which receives numerous accolades, is a 6.0-liter, 353-hp V8 with 373 ft-lbs of torque, matched to a 6-speed Allison automatic. You can also opt for the turbodiesel 6.6-liter V8 that gets 365-hp and 660 ft-lbs.
The Work Truck is basic, but starts out with power features and a Pure Pickup interior (dual glovebox, easier to grab controls and handles, more storage), while the SLE adds a few more conveniences, such as cruise control. The SLT features a Luxury interior, with leather and chrome trim and heated seats. All trims offer ABS brakes, OnStar, dual front airbags, and a CD/MP3 layer. There are nice options such as a DVD player, navigation system, sunroof, and rail tracks for the pickup bed.
The dash is set lower into the floor for better overall visibility, and two-row cabs are configured in stadium-style seating so rear passengers sit higher up. Rear seats also split-fold. The lack of stability control and standard side airbags (these can be added) and low fuel economy aren't appealing to owners, but these negatives don't seem to make a dent in the 2008 Sierra 2500HD's reputation for a smooth quiet ride, great handling, superior towing capability, and refined interior and equipment list.
What owners say
"Owners generally appreciate the 2008 GMC Sierra 2500HD for its powerful performance, comfort, and good value compared to competitors. Many drivers are impressed with how well it tows heavy loads and the overall ride quality. However, some concerns were raised about the price, condition issues, and fuel economy in stop-and-go traffic."
I have had my '08 2500HD Extended Cab (6.0L gas V8, 4x4) for almost two years now, and have driven it nearly 27K miles. This is the first truck I've owned that I have no desire to get rid of. The 2500HD provides a great combination of performance, comfort, capability, and quality, all for a price that is less than its major competitors. The best features of the 2500HD are: --Power. Even with the gas V8, you are pressed back in the seat when you step on it. This power is valuable when towing. I tow a 5,000 lb. trailer from time to time, which is a breeze for this truck to handle. --Comfort. The seats, driving position, and ride are excellent for long rides. You sit high up, and the low dashboard provides a great view out. All interior controls and displays are attractive and easy to use. The front seats have multiple adjustments and the cloth fabric is soft with support in the right areas. And the stock sound system pumps out the music with great sound quality. --Value. The 2500HD I bought was almost $10,000 cheaper than a Ford Super Duty with similar options. And to top it off, gas mileage even with the gas V8 has been pretty amazing for a 3/4 ton truck. With the cruise control set at 72 mph, I average 17 mpg on the interstate. On rural roads with speeds around 55-60, I even hit 18 mpg once. On the flip side, around town, in stop and go traffic, economy drops significantly to around 11-12.
July 22, 2009Tows great, with plenty of power. All buttons and functions are useful and easy to use. Decent ride for such a long truck. The gas mileage is not bad for being a truck. There is plenty of cargo room both inside and out!
February 9, 2015Ride is comfortable. Interior is great for pickup truck. Plenty of leg room in back and front seats. Powerful 6.0L Engine has plenty of pull for anything you can put behind a 2500. Excellent tow capibilities with integrated brake system.
