Edmunds' Expert Review

by the Edmunds Experts

Pros

Strong engine choices, multiple drivetrain options, impressive towing and hauling ability.

Cons

Lacks refinement and some key safety features compared to rivals, some low-grade cabin materials.

What’s new

Signifying the end of this generation's run, the 2007 GMC Sierra 2500HD becomes a "Classic" to distinguish itself from the redesigned truck that arrives later in 2007. Minor changes this year include standard tow hooks and a few features, such as a six-disc CD changer and steering-wheel-mounted controls, added to the SLE trims.

Edmunds says

If maximum capability and functionality are more important to you than refinement, the 2007 GMC Sierra 2500HD Classic is a tough truck to beat.

Vehicle overview

Entering the seventh year in its current guise, this generation of the Sierra 2500HD gains the word "Classic" in its name to help differentiate it from a fully redesigned Sierra that debuts later in the 2007 model year. Despite the 2007 Sierra 2500HD Classic's age, all of the traditional strengths of this big GMC pickup truck still stand, such as handsome styling and a lineup of impressively capable powertrains.

Although the "Classic" is pretty much a carryover, GMC did make a number of changes last year. They included some major upgrades to the optional Duramax diesel engine that provided the heavy-duty truck with best-in-class power ratings of 360 horsepower and 650 pound-feet of torque. As if that wasn't enough, the Allison automatic transmission was upgraded with an extra gear for a total of six. It's another overdrive gear designed for maximum fuel economy on the highway.

That strong combination puts the 2007 GMC Sierra 2500HD Classic head and shoulders above the competition when it's time for some serious towing. You can't go wrong with any of the powertrain choices, as they all provide strong performance and respectable towing capacities. But if you're very serious about towing heavy loads, the Duramax diesel is the way to go.

Some of the less flattering aspects of this outgoing heavy-duty truck are its lack of key safety features like side airbags and stability control, and questionable fit and finish inside the cabin. Still, the Sierra 2500HD Classic boasts immense capabilities, classic styling and many available features. Buyers interested in a workhorse pickup will want to give it consideration.

Performance & mpg

The engine lineup starts with the 6.0-liter V8 (300 hp, 360 lb-ft of torque). Should that not suffice, one can opt for the 8.1-liter V8 (330 hp, 450 lb-ft of torque) or the even stouter 6.6-liter Duramax diesel V8 (360 hp, 650 lb-ft of torque). The 6.0-liter V8 has a five-speed manual standard, with a heavy-duty four-speed automatic optional. The 8.1-liter V8 and the Duramax diesel come with the six-speed Allison automatic only. When it's time to work, the 2007 GMC Sierra 2500HD Classic is more than capable of hauling heavy loads. Maximum tow capacity varies depending on configuration, but the most common limit, properly equipped, is 12,000 pounds. Two- and four-wheel-drive models are available.

Safety

Antilock brakes are standard and traction control is optional. But several state-of-the-art safety features, such as stability control and side curtain airbags, are not available. In NHTSA frontal-impact crash testing, the GMC Sierra Classic received a rating of four stars (out of a possible five) for the driver and three stars for the front passenger.

Driving

Make no mistake; heavy-duty trucks of this ilk are happiest when working. Performance is strong and seamless, especially with the Duramax engine option. And the 2007 GMC Sierra 2500HD Classic is stable when working -- with the bed loaded up, the truck remains composed, with minimal sway on curvy roads, even in heavy crosswinds. Around town, the Sierra's ride is comfortable enough for daily driver use, but on the highway with an empty bed, it can get jittery over expansion joints, due to the stiff suspension calibrations required to handle heavy loads. Though it tracks straight and corners fairly well, steering feel is basically nonexistent; there's little feedback in a straight line and it's not any better through corners. Likewise, the brakes have a non-linear feel through the pedal, despite being quite effective when it comes to actual stopping distances.

Interior

Clear gauges, simple controls and comfortable seats are the strong points of the Sierra's cabin. There is plenty of room for six passengers and the crew cab configuration makes for easy entry and exit. Downsides include mediocre materials and inconsistent build quality. Long trips are easy to take, thanks to effective sound insulation and the availability of satellite radio and a DVD entertainment system.

2007 GMC Sierra 2500HD Classic models

A variety of cab and bed styles are available for the 2007 GMC Sierra 2500HD Classic heavy-duty truck. There are regular, extended cab and crew cab body styles. Regular cabs can be matched to a short or long bed, while extended and crew cabs are short-bed only. There are four trim levels: bare-bones Work Truck, base-model SL, midgrade SLE (which actually has two subsets: SLE1 and SLE2) and luxury SLT. Work Trucks are pretty basic but do have dual-zone air-conditioning, a 40/20/40-split bench seat, a tilt steering wheel and AM/FM radio. The SL adds upgraded upholstery, cruise control and a CD player as well as chrome trim for the grille and rear bumper. Power windows and locks, remote keyless entry and foglamps are part of the SLE1 style, while the SLE2 features automatic climate control, Bose audio and a power driver seat. The range-topping SLT adds aluminum wheels and leather upholstery. Major options for lower trims include power locks and upgraded cloth seating, while uplevel SLE and SLT trims allow access to OnStar, a rear-seat DVD entertainment system, a sunroof and satellite radio.

GMC Duramax

SLT 4dr Extended Cab 4WD SB (6.0L 8cyl 4A)

The Duramax 6L diesel is more than I expected. Not only is it quit, it rides like a dream. This engine also has the power to move anything I hook up to. The layout of the interior is excelent, everything right where I can reach it. This was a very good buy for me.

Awesome truck

SL1 4dr Crew Cab SB (6.0L 8cyl 4A)

Traded my 2006 Sierra 2500HD 6.0 V8 for the Allison/Duramax. Super truck. I was amazed how much better the ride is in the 2007 Sierra Classic. Duramax/Allison combo a real delight to tow with. The Allison 6 speed works incredibly well with the Duramax to couple all of that torque to the ground as well as assisting in stopping the whole load. Torque comes in at about 1500 RPMS and this …

Best vehicle I have ever owned

SLT 4dr Extended Cab 4WD SB (6.0L 8cyl 4A)

The four wheel on the fly is critical for me. The awesome power this engine generates is amazing. The ride quality will rival expensive luxury cars. People ask me all the time if it is really a diesel because it is so quiet. They are also impressed with the acceleration, ride quality, and quietness when they ride with me. I will buy another GMC diesel when this one is worn out...in about …

The best HD on the market

sam,07/07/2007

SLT 4dr Crew Cab 4WD SB (6.0L 8cyl 4A)

I drove the '08 Ford and '07 Dodge and none come close to the GMC. This is my second GM truck. I'm very hapy with it. The power is great. The only draw back is the mileage, but I was expecting that from a big truck.

Should I lease or buy a 2007 GMC Sierra 2500HD Classic?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
