2021 GMC Sierra 2500 HD assessment: Monster truck


Make no mistake, this truck is big.

Heavy-duty vans are special-purpose instruments designed to tow immense masses and haul mountains of stuff in every kind of situations. Like different HD pickups, the 2021 GMC Sierra 2500 AT4’s common lack of refinement, low gasoline effectivity and ponderous dynamics make dwelling with it everyday a problem when you do not want the huge functionality it affords.

Offering a bit of additional model and off-road functionality, the Sierra 2500 AT4 fashions function darkish chrome exterior accents, body-color bumpers and a daring grille design. The usual bright-red restoration hooks look nice and ought to be tremendous helpful on the path. Making certain this truck can take you out into the wilderness, it comes with Rancho shocks, a locking rear differential and customary 18-inch wheels with Michelin all-terrain tires, although this instance rolls on swanky 20-inch rims.

Greater is not at all times higher

With a crew-cab physique and off-road suspension, this Sierra is gigantic, a couple of trailer hitch in need of 21 toes in size, and that is with simply the 82-inch, standard-length mattress. Its elevated cab provides you skyscraper views of surrounding site visitors and makes climbing onboard a chore. Excluding the gargantuan telescopic towing mirrors, its physique is not any wider than a GMC Sierra or Chevy Silverado 1500’s, however this factor feels prefer it takes up a lane and a half, a sensation that is accentuated by its virtually comically raised hood that partly obscures ahead visibility and frightens pets and babies.

Maneuverability is a problem with this truck. Parking could be anxious, and I instinctively swing vast for each flip to keep away from clipping curbs or scraping different autos. The Sierra 2500 is not actually any larger than rival heavy-duty pickups from Ford and Ram, however it certain feels a dimension or two bigger.

Serving to make issues just a little extra manageable, GMC affords a variety of helpful applied sciences. The obtainable ProGrade Trailering system, for example, offers as much as 15 completely different digicam views. This features a neat transparent-trailer function that makes use of video to make it appear to be there’s nothing behind the truck. A rear digicam mirror can be provided, which shows real-time video on a display mounted beneath the rear-view mirror glass, offering a a lot wider discipline of view.

For folk who often tow, this truck affords a great deal of intelligent options that may make it a lot much less anxious. A intelligent computerized electrical parking brake retains the truck from rolling that small quantity once you shift into park, one thing that may make hooking up a trailer fairly irritating. The towing mirrors can prolong or retract on the push of a button, hill-start help and hill-descent management assist maintain masses protected and safe when traversing mountainous terrain, and tow/haul mode will even stay engaged on the subsequent key cycle so you do not have to manually flip it on once more. That is all nice stuff, however maybe the Sierra’s cleverest function is definitely its easiest one.

20-inch wheels look downright tiny on this massive truck.

By the numbers

So that you at all times know precisely what your explicit truck is rated to tow or haul, GMC features a sticker on the door jamb that spells all the pieces out, just like the gross car weight score, most payload, standard trailering capability, curb weight and extra. This takes the guesswork out of how a lot you’ll be able to safely deal with.

Flexing its muscular tissues, this Sierra 2500’s most payload score is 3,232 kilos and it might tow as much as 14,500 kilos with the hitch. Hook a gooseneck trailer up as a substitute, and that determine will increase to a formidable 16,620 kilos.

Yet one more variety of word: six. That is what number of capabilities the Sierra’s obtainable MultiPro Tailgate affords. This is without doubt one of the most modern pickup truck options to return out within the final 20 years. This ingenious setup has what quantities to a small gate inside the primary tailgate, which helps you to haul freight extra securely, simply attain objects saved within the mattress and it even works as a step so you’ll be able to conveniently climb into the cargo field.

The MultiPro Tailgate is without doubt one of the Sierra’s most modern options.

Modest efficiency, conceited consumption

The Sierra 2500’s customary 6.6-liter gasoline V8 is potent sounding and clean operating, however even with the truck mattress empty and no trailer in tow it feels overmatched. Regardless of having direct gasoline injection and even variable valve timing, this engine simply does not appear to carry out like one thing with 401 horsepower and 464 pound-feet of torque ought to. It is not notably punchy round city, and merging onto the freeway takes longer than anticipated, the silky and astute six-speed computerized transmission doing its finest to assist get this rig up to the mark. I blame the Sierra’s towering physique, mammoth frontal space and ready-for-action weight of seven,418 kilos for this pokey efficiency. Drivers who want extra functionality and confidence (or simply need to roll some coal) can get a 6.6-liter Duramax diesel matched with a 10-speed gearbox, although you pay by the nostril for the privilege of burning oil. This powertrain provides about 10 grand to the truck’s price ticket.

Because the Sierra 2500’s gross car weight score is larger than 8,500 kilos, it is exempt from fuel-economy testing. Nonetheless, unladen, in real-world driving, I’ve averaged round 14 miles per gallon in line with the journey pc, which is not too horrible for one thing of this dimension and weight.

The truck’s experience is unquestionably on the agency facet, however it’s not so starchy that it crashes over bumps or shatters your backbone. The experience is a contact harsher than I might like, however this stiffness is important so you are not sitting on the bump stops when the mattress’s filled with cargo. Load this GMC up with bricks, gravel or a twine or two of firewood and I guess it could experience rattling close to like a Lexus. The Sierra’s steering is gradual and imprecise, plus it is susceptible to let the truck wander a bit, however the impartial entrance suspension provides it an edge over competing heavy-duty vans, which nonetheless include stable entrance axles.

This inside is boring and drab.

Big truck, tiny screens

GM’s current-generation pickups will not be identified for his or her stellar interiors. Silverado and Sierra cabins in each light- and heavy-duty type are low-budget affairs fabricated from unattractive laborious plastic. The seats are flat, and most of the secondary controls are of low high quality. Ram has a transparent benefit on this space and even Ford’s older vans are a hair nicer.

The Sierra AT4’s infotainment system with built-in navigation is simple to make use of and responsive, however it’s displayed on an 8-inch touchscreen that appears tiny on such an expansive dashboard. Additional cheapening the expertise, this panel’s viewing angles will not be nice, with the colours simply washing out.

The $7,975 AT4 Premium Package deal features a vary of facilities akin to Apple CarPlay and Android Auto that each join wirelessly, rear cross-traffic alert, entrance and rear parking sensors and computerized excessive beams. It additionally will get you a transparent and crisp head-up show and GMC’s Security Alert Seat, which vibrates to warn the motive force of hazard.

The Sierra HD is one robust truck.

Consolation on this truck is combined. The 10-way power-adjustable driver’s chair is agency however practically freed from any bolstering. It is lower for somebody a number of instances heavier than me. The backseat, nevertheless, is kind of good, providing warmth for the outboard passengers and miles of legroom due to the crew-cab physique.

Pony up, cowboy

Along with that AT4 Premium Package deal, this Sierra 2500 additionally options vibrant Cayenne Pink Tintcoat paint, a $645 possibility, plus it is fitted with the $545 gooseneck/fifth-wheel prep possibility. Together with $1,595 in vacation spot charges, it checks out for $68,160, a steep worth to make sure, however one which’s not completely unreasonable for the aptitude it affords. That determine can be in keeping with a comparably geared up Ram Energy Wagon or a Ford F-250 with the Tremor bundle.

The 2021 GMC Sierra 2500 is succesful and hard-working. It is a truck I can respect, even when it is one I do not love.
