Big and fresh as always GMC The Sierra 2500 will continue until 2022 without any significant changes. One step below top-class Denali, the AT4 is this truck’s off-road model, which has minor visual adjustments and slightly improved off-pave performance.
In addition to a two-speed gearbox, AT4s have ground control, sliding plates to protect fragile mechanical components and a special off-road suspension with Rancho dampers. AT4 Models are only offered with an extra spacious crew cabin, although two bed lengths are available: 82.2 inches and 98.3 inches. Thanks to smart engineering, these boxes promise the best volume in the class, which is ideal for transporting more gravel, wood or furniture per load. The Sierra 2500 makes it easier to reach objects stored in its high, shoulder-height bed, and has integrated side steps and cut-outs in the rear bumper.
Covering that cargo box is one available MultiPro tailgate, one of the most innovative pickup features released in several years. With six different stands, this gate makes it easier for you to support loads, it provides a steady step into the bed, helps keep different sizes of load safe and even works as a small work surface, a place to set up your laptop computer or clipboard. Ford’s latest tailgates can not handle this and even Ram’s innovative multifunction gate is not as useful.
No surprise, there’s no groundbreaking under this truck’s soaring hood. Two engines are offered: a petrol V8 and a proven 6.6-liter Duramax diesel. If you can afford the full $ 9,890 in recharging and have serious work to do, get the optional oil burner, which comes with a 10-speed Allison gearbox. This combination is dynamite, completely superior to the standard engine of the Sierra HD. In fact, this may be the best driveline for heavy trucks in the industry. Duramax delivers 445 horsepower and 910 pounds-feet of torque, slightly behind diesel-powered Ford and Bagge trucks in the twist department, although the difference is academic. This GMC is still surprisingly fast and the engine super smooth, with no unpleasant vibrations or rattles. The transmission’s performance is also perfect. It shifts with softness in luxury cars and never stumbles.
This diesel-powered Sierra 2500 AT4 can pull up to 3,029 pounds and pull a maximum of 18,500 pounds, either conventionally or with a turntable / gooseneck. The large exterior mirrors that not only have convex reflectors, but protrude and fold with the push of a button, make towing a little less stressful.
To enable this impressive capability, the Sierra has an independent front suspension with torsion bars. On the back is your traditional live shaft supported by leaf springs. Predictably, this installation provides a ride that is quite stiff, even if it is not brutal even unloaded. Throw a few hundred pounds in bed and things even out noticeably. This truck’s circulating ball control is quite accurate and does not require constant attention to track straight, although the excessively high, square hood makes it a challenge to place this truck in its lane.
Not to fuck a dead horse, but the Sierra 2500’s interior is not good. This truck and its lightweight siblings have lagged behind in recent years with cabs that are clearly behind the competition, loaded with hard, unattractive plastic, matte leather and mediocre technology. Fortunately, help is on the way for halftone versions of Chevy Silverado and GMC Sierra least. The updated 2022 models have dramatically renewed excavations, with greatly improved materials and features. GM has not said whether these refurbished interiors will find its way to the strong line, but it is a good bet that they will do so, and hopefully soon.
It’s easy to downplay the Sierra’s interior, but not everything is bad. The ergonomics, for example, are solid. This truck’s climate and sound switches are very simple and the trailer’s brake controls are clearly visible and easy to reach, located near the bottom of the center stack. If the load you pull starts to get a little fresh, you’ll be glad it’s not hard to find. I also love the old school’s column mounted gear lever. It is more tactile and satisfying than a steering wheel or buttons.
The Sierra 2500’s elevated ride height provides panoramic views of the surrounding traffic, even if the comfort is unbeatable. The front bucket seats are fixed and flat, with some reinforcement and even smaller contours. The rear accommodations in this model with crew cabin are similar, although there is plenty of room for passengers with real legroom. For added versatility, the split rear cushion lifts, reveals additional storage corners or allows you to carry bulky loads. In an ingenious way, the backrest of the rear seat also has hidden storage compartments, which are a good place to store smaller objects from prying eyes.
Along with comfort, tech is a mixed bag in this rig. The available 8-inch infotainment screen with embedded navigation looks small on such a huge dashboard. The viewing angles of the screen are also mediocre, with everything looking washed from the driver’s seat. But hey, at least GMC nailed the infotainment system. It’s super responsive, easy to navigate and the sharp icons look great. Beyond that, Android Auto and Apple CarPlay is supported and both smartphone mirroring systems can connect wirelessly.
A bunch of must-have treats are included in the $ 7,975 AT4 Premium Plus package. This expensive option group includes a cordless phone charger, sliding rear window and Bose sound system. Advanced driver aids such as rear cross traffic warning, lane change warning, a rear camera mirror and automatic high beam are also included – features that, if not mandatory in a bulky vehicle like this, are certainly nice to have.
Among other things, the AT4 Premium Plus package also comes with GM’s excellent HD Surround Vision 360-degree camera system, which provides up to 15 views and is a godsend when parking or connecting a trailer. A Safety Alert chair is also included, which buzzes in the buttocks to warn of a possible collision ahead or if you cross a file marking.
This Sierra’s price matches its size and weight. As tested, this truck checks out for $ 78,005 which attracts jerks including $ 1,695 in destination fees. There is a lot to pay for a tool, even if it is right in line with the competition. Skip some very desirable options – such as the diesel engine and the premium package – and you can get a base model AT4 for about 62 thousand kroner, which is a little more reasonable.
Of course, if you requires a heavy truck it really does not matter what they cost. You can not tow a horse trailer with one Toyota Corolla. The Sierra 2500 really has its strengths, although rival trucks beat it in some key areas.
