Heavy-duty trucks are specific-goal applications designed to tow immense masses and haul mountains of things in all kinds of disorders. Like other High definition pickups, the 2021 GMC Sierra 2500 AT4’s general absence of refinement, reduced gas effectiveness and ponderous dynamics make living with it day to day a problem if you you should not have to have the large capacity it offers.


  • Towing and hauling capacity
  • Refined powertrain
  • Ingenious tailgate

Really don’t Like

  • Lackluster effectiveness
  • Same outdated interior
  • Brash styling

Furnishing a bit of extra design and off-street capacity, the Sierra 2500 AT4 models feature dim chrome exterior accents, human body-coloration bumpers and a daring grille design and style. The typical dazzling-crimson restoration hooks appear terrific and should really be super useful on the trail. Making certain this truck can acquire you out into the wilderness, it will come with Rancho shocks, a locking rear differential and typical 18-inch wheels with Michelin all-terrain tires, nevertheless this illustration rolls on swanky 20-inch rims.

Even larger is just not constantly superior

With a crew-taxi human body and off-street suspension, this Sierra is monumental, about a trailer hitch limited of 21 toes in duration, and that’s with just the eighty two-inch, typical-duration bed. Its elevated taxi gives you skyscraper sights of surrounding traffic and tends to make climbing onboard a chore. Excluding the gargantuan telescopic towing mirrors, its human body is no broader than a GMC Sierra or Chevy Silverado 1500’s, but this factor feels like it will take up a lane and a 50 percent, a sensation that’s accentuated by its virtually comically elevated hood that partly obscures ahead visibility and frightens pets and small little ones.

Maneuverability is a problem with this truck. Parking can be nerve-racking, and I instinctively swing wide for just about every convert to steer clear of clipping curbs or scraping other motor vehicles. The Sierra 2500 is just not truly any larger than rival weighty-duty pickups from Ford and Ram, but it confident feels a dimensions or two much larger.

Helping make items a very little far more manageable, GMC offers a range of useful technologies. The accessible ProGrade Trailering procedure, for occasion, provides up to 15 unique camera sights. This incorporates a neat transparent-trailer feature that employs movie to make it appear like you will find absolutely nothing driving the truck. A rear camera mirror is also made available, which displays serious-time movie on a screen mounted underneath the rear-check out mirror glass, providing a considerably broader field of check out.

For people who regularly tow, this truck offers masses of clever functions that can make it considerably a lot less nerve-racking. A clever automated electric parking brake retains the truck from rolling that small volume when you shift into park, a thing that can make hooking up a trailer really annoying. The towing mirrors can extend or retract at the push of a button, hill-get started assist and hill-descent regulate assistance continue to keep masses harmless and protected when traversing mountainous terrain, and tow/haul manner will even remain engaged at the following key cycle so you you should not have to manually convert it on once more. This is all terrific things, but perhaps the Sierra’s cleverest feature is really its most straightforward just one.

20-inch wheels appear downright small on this huge truck.

By the figures

So you constantly know specifically what your individual truck is rated to tow or haul, GMC incorporates a sticker on the doorway jamb that spells everything out, like the gross vehicle fat ranking, optimum payload, regular trailering capacity, suppress fat and far more. This will take the guesswork out of how considerably you can properly handle.

Flexing its muscle mass, this Sierra 2500’s optimum payload ranking is three,232 pounds and it can tow up to fourteen,500 pounds with the hitch. Hook a gooseneck trailer up rather, and that determine raises to an remarkable 16,620 pounds.

A person far more quantity of notice: 6. Which is how lots of capabilities the Sierra’s accessible MultiPro Tailgate offers. This is just one of the most innovative pickup truck functions to occur out in the last 20 decades. This ingenious set up has what quantities to a small gate within just the major tailgate, which lets you haul freight far more securely, quickly access objects saved in the bed and it even works as a action so you can conveniently climb into the cargo box.

The MultiPro Tailgate is just one of the Sierra’s most innovative functions.

Modest effectiveness, immodest intake

The Sierra 2500’s typical 6.6-liter gasoline V8 is powerful sounding and clean running, but even with the truck bed empty and no trailer in tow it feels overmatched. Inspite of acquiring direct gas injection and even variable valve timing, this motor just isn’t going to look to perform like a thing with 401 horsepower and 464 pound-toes of torque should really. It really is not especially punchy all over city, and merging on to the highway will take lengthier than anticipated, the silky and astute 6-velocity automated transmission performing its ideal to assistance get this rig up to velocity. I blame the Sierra’s towering human body, mammoth frontal area and completely ready-for-action fat of seven,418 pounds for this pokey effectiveness. Motorists who have to have far more capacity and confidence (or just want to roll some coal) can get a 6.6-liter Duramax diesel matched with a ten-velocity gearbox, nevertheless you spend as a result of the nose for the privilege of burning oil. This powertrain adds about ten grand to the truck’s price tag tag.

Considering that the Sierra 2500’s gross vehicle fat ranking is bigger than 8,500 pounds, it is really exempt from gas-financial state tests. Continue to, unladen, in serious-earth driving, I’ve averaged all over fourteen miles for every gallon in accordance to the journey personal computer, which is just not as well horrible for a thing of this dimensions and fat.

The truck’s journey is surely on the company side, but it is really not so starchy that it crashes about bumps or shatters your spine. The journey is a contact harsher than I’d like, but this stiffness is required so you’re not sitting on the bump stops when the bed’s entire of cargo. Load this GMC up with bricks, gravel or a twine or two of firewood and I bet it would journey damn around like a Lexus. The Sierra’s steering is gradual and imprecise, as well as it is really prone to let the truck wander a bit, but the independent entrance suspension gives it an edge about competing weighty-duty trucks, which nevertheless occur with good entrance axles.

This interior is boring and drab.

Huge truck, small screens

GM’s present-day-era pickups are not acknowledged for their stellar interiors. Silverado and Sierra cabins in the two mild- and weighty-duty sort are reduced-funds affairs designed of unattractive difficult plastic. The seats are flat, and lots of of the secondary controls are of reduced high-quality. Ram has a very clear edge in this area and even Ford’s older trucks are a hair nicer.

The Sierra AT4’s infotainment procedure with integrated navigation is quick to use and responsive, but it is really displayed on an 8-inch touchscreen that looks small on these an expansive dashboard. Further cheapening the expertise, this panel’s viewing angles are not terrific, with the hues quickly washing out.

The $seven,975 AT4 High quality Deal incorporates a range of features these as Apple CarPlay and Android Car that the two join wirelessly, rear cross-traffic alert, entrance and rear parking sensors and automated superior beams. It also gets you a very clear and crisp head-up exhibit and GMC’s Basic safety Notify Seat, which vibrates to warn the driver of hazard.

The Sierra High definition is just one hard truck.

Craig Cole/Roadshow

Ease and comfort in this truck is blended. The ten-way energy-adjustable driver’s chair is company but nearly no cost of any bolstering. It really is slash for a person several situations heavier than me. The backseat, nonetheless, is really awesome, providing warmth for the outboard passengers and miles of legroom many thanks to the crew-taxi human body.

Pony up, cowboy

In addition to that AT4 High quality Deal, this Sierra 2500 also functions lively Cayenne Purple Tintcoat paint, a $645 choice, as well as it is really equipped with the $545 gooseneck/fifth-wheel prep choice. Which include $one,595 in destination costs, it checks out for $sixty eight,160, a steep price tag to be certain, but just one that’s not completely unreasonable for the capacity it offers. That determine is also in line with a comparably geared up Ram Electricity Wagon or a Ford F-250 with the Tremor package.

The 2021 GMC Sierra 2500 is able and difficult-doing the job. It really is a truck I can regard, even if it is really just one I you should not love.
