2021 GMC Sierra 2500 HD review: Monster truck

Make no error, this truck is huge.

Craig Cole/Roadshow

Large-responsibility vans are distinctive-purpose instruments created to tow huge loads and haul mountains of things in all forms of problems. Like other Hd pickups, the 2021 GMC Sierra 2500 AT4’s common absence of refinement, minimal gasoline performance and ponderous dynamics make residing with it day to day a problem if you really don’t need the vast capability it offers.


  • Towing and hauling capability
  • Refined powertrain
  • Ingenious tailgate

Do not Like

  • Lackluster functionality
  • Similar old interior
  • Brash styling

Delivering a little bit of added model and off-road capability, the Sierra 2500 AT4 versions function dim chrome exterior accents, human body-shade bumpers and a bold grille design. The typical bright-pink recovery hooks glimpse wonderful and should be super handy on the trail. Ensuring this truck can acquire you out into the wilderness, it will come with Rancho shocks, a locking rear differential and typical eighteen-inch wheels with Michelin all-terrain tires, nevertheless this case in point rolls on swanky twenty-inch rims.

More substantial is not constantly greater

With a crew-taxi human body and off-road suspension, this Sierra is huge, about a trailer hitch quick of 21 feet in size, and which is with just the eighty two-inch, typical-size bed. Its elevated taxi presents you skyscraper sights of surrounding site visitors 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 issue feels like it requires up a lane and a fifty percent, a feeling which is accentuated by its virtually comically elevated hood that partly obscures ahead visibility and frightens pets and compact little ones.

Maneuverability is a problem with this truck. Parking can be tense, and I instinctively swing huge for just about every switch to avoid clipping curbs or scraping other autos. The Sierra 2500 is not seriously any even larger than rival major-responsibility pickups from Ford and Ram, but it confident feels a size or two larger.

Encouraging make things a tiny a lot more manageable, GMC offers a vary of handy systems. The obtainable ProGrade Trailering procedure, for instance, offers up to fifteen distinct digicam sights. This incorporates a neat clear-trailer function that employs video to make it glimpse like there is practically nothing behind the truck. A rear digicam mirror is also made available, which displays authentic-time video on a screen mounted underneath the rear-watch mirror glass, supplying a much broader subject of watch.

For people who regularly tow, this truck offers loads of clever attributes that can make it much a lot less tense. A clever automatic electric powered parking brake retains the truck from rolling that compact volume when you change into park, anything that can make hooking up a trailer pretty discouraging. The towing mirrors can extend or retract at the drive of a button, hill-start off help and hill-descent handle aid retain loads safe and safe when traversing mountainous terrain, and tow/haul method will even stay engaged at the up coming critical cycle so you really don’t have to manually switch it on once again. This is all wonderful things, but potentially the Sierra’s cleverest function is in fact its easiest 1.

twenty-inch wheels glimpse downright very small on this huge truck.

By the quantities

So you constantly know just what your individual truck is rated to tow or haul, GMC incorporates a sticker on the doorway jamb that spells all the things out, like the gross automobile weight ranking, maximum payload, regular trailering potential, control weight and a lot more. This requires the guesswork out of how much you can safely manage.

Flexing its muscle tissues, this Sierra 2500’s maximum payload ranking is three,232 lbs and it can tow up to fourteen,500 lbs with the hitch. Hook a gooseneck trailer up instead, and that figure raises to an extraordinary 16,620 lbs.

One a lot more number of take note: six. That’s how several capabilities the Sierra’s obtainable MultiPro Tailgate offers. This is 1 of the most ground breaking pickup truck attributes to occur out in the previous twenty decades. This ingenious setup has what amounts to a compact gate within the major tailgate, which lets you haul freight a lot more securely, simply arrive at merchandise saved in the bed and it even is effective as a move so you can conveniently climb into the cargo box.

The MultiPro Tailgate is 1 of the Sierra’s most ground breaking attributes.

Modest functionality, conceited consumption

The Sierra 2500’s typical 6.6-liter gasoline V8 is powerful sounding and easy running, but even with the truck bed empty and no trailer in tow it feels overmatched. Inspite of having immediate gasoline injection and even variable valve timing, this engine just isn’t going to look to complete like anything with 401 horsepower and 464 pound-feet of torque should. It is really not specially punchy all over city, and merging on to the highway requires for a longer time than predicted, the silky and astute six-velocity automatic transmission doing its most effective to aid get this rig up to velocity. I blame the Sierra’s towering human body, mammoth frontal space and completely ready-for-motion weight of seven,418 lbs for this pokey functionality. Drivers who need a lot more capability and self-assurance (or just want to roll some coal) can get a 6.6-liter Duramax diesel matched with a ten-velocity gearbox, nevertheless you pay via the nose for the privilege of burning oil. This powertrain provides about ten grand to the truck’s rate tag.

Given that the Sierra 2500’s gross automobile weight ranking is better than eight,500 lbs, it can be exempt from gasoline-economic system testing. Nevertheless, unladen, in authentic-planet driving, I have averaged all over fourteen miles for every gallon in accordance to the trip computer system, which is not way too terrible for anything of this size and weight.

The truck’s experience is definitely on the company side, but it can be not so starchy that it crashes above bumps or shatters your backbone. The experience is a contact harsher than I would like, but this stiffness is necessary so you are not sitting on the bump stops when the bed’s complete of cargo. Load this GMC up with bricks, gravel or a wire or two of firewood and I bet it would experience damn in close proximity to like a Lexus. The Sierra’s steering is sluggish and imprecise, plus it can be vulnerable to enable the truck wander a little bit, but the impartial front suspension presents it an edge above competing major-responsibility vans, which nevertheless occur with good front axles.

This interior is uninteresting and drab.

Large truck, very small screens

GM’s existing-technology pickups are not known for their stellar interiors. Silverado and Sierra cabins in equally light- and major-responsibility type are minimal-finances affairs created of unattractive really hard plastic. The seats are flat, and several of the secondary controls are of minimal high quality. Ram has a very clear edge in this space and even Ford’s older vans are a hair nicer.

The Sierra AT4’s infotainment procedure with built-in navigation is straightforward to use and responsive, but it can be shown on an eight-inch touchscreen that seems to be very small on this sort of an expansive dashboard. More cheapening the encounter, this panel’s viewing angles are not wonderful, with the colours simply washing out.

The $seven,975 AT4 Quality Package incorporates a vary of features this sort of as Apple CarPlay and Android Auto that equally connect wirelessly, rear cross-site visitors warn, front and rear parking sensors and automatic high beams. It also receives you a very clear and crisp head-up show and GMC’s Protection Alert Seat, which vibrates to warn the driver of danger.

The Sierra Hd is 1 difficult truck.

Comfort in this truck is combined. The ten-way electricity-adjustable driver’s chair is company but nearly no cost of any bolstering. It is really minimize for a person numerous situations heavier than me. The backseat, having said that, is pretty great, presenting heat for the outboard passengers and miles of legroom thanks to the crew-taxi human body.

Pony up, cowboy

In addition to that AT4 Quality Package, this Sierra 2500 also attributes vivid Cayenne Purple Tintcoat paint, a $645 alternative, plus it can be fitted with the $545 gooseneck/fifth-wheel prep alternative. Like $one,595 in location charges, it checks out for $sixty eight,160, a steep rate to be specified, but 1 which is not thoroughly unreasonable for the capability it offers. That figure is also in line with a comparably geared up Ram Power Wagon or a Ford F-250 with the Tremor package deal.

The 2021 GMC Sierra 2500 is capable and really hard-performing. It is really a truck I can regard, even if it can be 1 I really don’t appreciate.
