Along with a two-speed switch case, AT4s have hill-descent management, skid plates to guard delicate mechanical parts and a particular off-road suspension with Rancho shocks. AT4 fashions are solely supplied with an extra-spacious crew-cab physique, although two mattress lengths can be found: 82.2 inches and 98.3 inches. Due to intelligent engineering, these packing containers promise best-in-class quantity, which is right for hauling extra gravel, firewood or furnishings per load. Making it only a contact simpler to achieve objects saved in its towering, shoulder-height mattress, the Sierra 2500 options built-in aspect steps and cutouts within the rear bumper.
Capping that cargo field is an accessible MultiPro tailgate, probably the most progressive pickup truck options to return out in years. With six completely different postures, this gate permits you to help masses extra simply, it gives a sturdy step into the mattress, helps maintain completely different sizes of cargo safe and even capabilities as a small work floor, a spot to set your laptop computer or clipboard. Ford’s newest tailgates cannot maintain a candle to this and even Ram’s progressive Multifunction gate is not as helpful.
No shock, there’s nothing groundbreaking beneath this truck’s hovering hood. Two engines are supplied: a gasoline V8 and a confirmed 6.6-liter Duramax diesel. When you can afford the whopping $9,890 upcharge and have severe work to do, get the elective oil-burner, which comes paired with a 10-speed Allison transmission. This combo is dynamite, hands-down superior to the Sierra HD’s customary engine. The truth is, this can be the perfect heavy-duty truck powertrain within the enterprise. The Duramax delivers 445 horsepower and 910 pound-feet of torque, barely behind diesel-powered Ford and Ram vehicles within the twist division, although the distinction is educational. This GMC remains to be surprisingly fast and the engine tremendous easy, with no obnoxious vibration or clattering. The transmission’s efficiency can be excellent. It shifts with luxury-car smoothness and by no means stumbles.
This diesel-powered Sierra 2500 AT4 can haul as much as 3,029 kilos and drag a most of 18,500 kilos, both conventionally or with a fifth-wheel/gooseneck trailer. Making towing just a bit much less worrying are massive exterior mirrors that not solely characteristic convex reflectors however prolong and fold on the push of a button.
Serving to allow this spectacular functionality, the Sierra options an unbiased entrance suspension with torsion bars. Out again is your conventional reside axle supported by leaf springs. Predictably, this setup gives a experience that is pretty stiff, although even unladen it isn’t brutal. Throw just a few hundred kilos within the mattress and issues easy out noticeably. This truck’s recirculating ball steering system in all fairness exact and does not require fixed consideration to trace straight, although the excessively tall, squared-off hood makes it a problem to put this truck in its lane.
To not bludgeon a deceased equine, however the Sierra 2500’s inside is not nice. This truck and its light-duty siblings have limped alongside for the previous few years with cabins which might be clearly behind the competitors, loaded with laborious, unattractive plastics, lackluster leather-based and middling tech. Fortunately, assistance is on the best way — for half-ton variations of the Chevy Silverado and GMC Sierra no less than. The up to date 2022 fashions characteristic dramatically revamped digs, with vastly improved supplies and options. GM hasn’t stated whether or not these redecorated interiors will discover their option to the heavy-duty line, however it’s an excellent wager they may, and hopefully briefly order.
It is easy to denigrate the Sierra’s inside, however not every thing is dangerous. The ergonomics, as an illustration, are stable. This truck’s local weather and audio switches are lifeless easy and the trailer brake controller is clearly seen and straightforward to achieve, positioned close to the underside of the middle stack. If the load you are dragging begins to get a little bit frisky, you will be glad this is not laborious to search out. I additionally love the old-school column-mounted shifter. It is extra tactile and satisfying than a dial or buttons.
The Sierra 2500’s elevated experience top gives vista-like views of surrounding visitors, although consolation is hit and miss. The entrance bucket seats are agency and flat, with little bolstering and even much less contouring. The rear lodging on this crew-cab mannequin are comparable, although there’s a ton of area for passengers with actual stretch-out legroom. For added versatility, that cut up rear cushion lifts, revealing extra storage nooks or permitting you to hold cumbersome cargo. Ingeniously, the rear seat backrests have hidden storage cubbies as effectively, that are an incredible place to stash smaller objects away from prying eyes.
Together with consolation, tech is a blended bag on this rig. The accessible 8-inch infotainment display screen with embedded navigation seems tiny on such an enormous dashboard. The show’s viewing angles are additionally mediocre, with every thing trying washed out from the motive force’s seat. However hey, no less than GMC nailed the infotainment system. It is tremendous responsive, simple as pie to navigate and the crisp icons look nice. Past that, Android Auto and Apple CarPlay are supported and each smartphone-mirroring methods can join wirelessly.
A bunch of must-have goodies are bundled within the $7,975 AT4 Premium Plus Package deal. This expensive choices group features a wi-fi cellphone charger, energy sliding rear window and Bose sound system. Superior driver aids like rear cross-traffic alert, lane-departure warning, a rear digicam mirror and automated excessive beams are included, too — options that, if not obligatory in a hulking car like this, positive are good to have.
Amongst different issues, the AT4 Premium Plus Package deal additionally comes with GM’s wonderful HD Encompass Imaginative and prescient 360-degree digicam system, which gives as much as 15 views and is a godsend when parking or hooking up a trailer. A Security Alert seat is included, too, which buzzes your butt to warn of a potential ahead collision or in the event you cross a lane marker.
Matching its dimension and weight is that this Sierra’s worth. As examined, this truck checks out for a wince-inducing $78,005 together with $1,695 in vacation spot charges. That is quite a bit to pay for a instrument, even whether it is proper according to the competitors. Skip just a few extremely fascinating choices — just like the diesel engine and premium bundle — and you may get a base AT4 mannequin for round 62 grand, which is a little more cheap.
After all, in the event you want a heavy-duty truck, it actually does not matter what they value. You possibly can’t tow a horse trailer with a Toyota Corolla. The Sierra 2500 definitely has its strengths, even when rival vehicles beat it in some essential areas.
