2021 GMC Sierra 2500 HD review: Monster truck

Make no oversight, this truck is big.


Craig Cole/Roadshow

Large-responsibility trucks are particular-reason equipment developed to tow immense loads and haul mountains of stuff in all sorts of conditions. Like other Hd pickups, the 2021 GMC Sierra 2500 AT4’s typical lack of refinement, low gasoline effectiveness and ponderous dynamics make dwelling with it day to day a obstacle if you really don’t want the huge capability it gives.

Really don’t Like

  • Lackluster effectiveness
  • Similar previous inside
  • Brash styling

Providing a little bit of more design and style and off-highway capability, the Sierra 2500 AT4 types attribute dark chrome exterior accents, body-color bumpers and a bold grille layout. The standard vibrant-red recovery hooks glimpse good and must be super helpful on the trail. Guaranteeing this truck can just take you out into the wilderness, it arrives with Rancho shocks, a locking rear differential and standard eighteen-inch wheels with Michelin all-terrain tires, though this example rolls on swanky twenty-inch rims.

Even bigger isn’t really usually far better

With a crew-taxi body and off-highway suspension, this Sierra is great, about a trailer hitch small of 21 toes in size, and that’s with just the 82-inch, standard-size mattress. Its elevated taxi presents you skyscraper views of encompassing traffic and makes climbing onboard a chore. Excluding the gargantuan telescopic towing mirrors, its 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 half, a sensation that’s accentuated by its just about comically elevated hood that partly obscures ahead visibility and frightens animals and compact young children.

Maneuverability is a obstacle with this truck. Parking can be nerve-racking, and I instinctively swing wide for each individual flip to stay away from clipping curbs or scraping other automobiles. The Sierra 2500 isn’t really definitely any even larger than rival heavy-responsibility pickups from Ford and Ram, but it absolutely sure feels a dimensions or two much larger.

Helping make things a minimal far more manageable, GMC gives a vary of helpful systems. The offered ProGrade Trailering system, for occasion, offers up to fifteen different digicam views. This involves a neat transparent-trailer attribute that utilizes online video to make it glimpse like you can find almost nothing at the rear of the truck. A rear digicam mirror is also made available, which displays true-time online video on a screen mounted underneath the rear-look at mirror glass, delivering a substantially broader area of look at.

For individuals who regularly tow, this truck gives loads of clever options that can make it substantially fewer nerve-racking. A clever computerized electric parking brake keeps the truck from rolling that compact volume when you shift into park, a thing that can make hooking up a trailer fairly irritating. The towing mirrors can prolong or retract at the force of a button, hill-get started assist and hill-descent regulate assistance preserve loads risk-free and safe when traversing mountainous terrain, and tow/haul manner will even continue being engaged at the subsequent critical cycle so you really don’t have to manually flip it on once again. This is all good stuff, but possibly the Sierra’s cleverest attribute is in fact its most basic a person.

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

By the quantities

So you usually know exactly what your particular truck is rated to tow or haul, GMC involves a sticker on the door jamb that spells almost everything out, like the gross auto weight rating, optimum payload, regular trailering ability, suppress weight and far more. This requires the guesswork out of how substantially you can safely take care of.

Flexing its muscle mass, this Sierra 2500’s optimum payload rating is three,232 kilos and it can tow up to fourteen,500 kilos with the hitch. Hook a gooseneck trailer up rather, and that determine will increase to an outstanding sixteen,620 kilos.

1 far more quantity of notice: 6. That’s how numerous capabilities the Sierra’s offered MultiPro Tailgate gives. This is a person of the most ground breaking pickup truck options to come out in the last twenty decades. This ingenious set up has what amounts to a compact gate in just the primary tailgate, which allows you haul freight far more securely, very easily get to goods stored in the mattress and it even works as a phase so you can conveniently climb into the cargo box.

The MultiPro Tailgate is a person of the Sierra’s most ground breaking options.

Modest effectiveness, immodest usage

The Sierra 2500’s standard 6.6-liter gasoline V8 is powerful sounding and sleek jogging, but even with the truck mattress empty and no trailer in tow it feels overmatched. Even with possessing direct gasoline injection and even variable valve timing, this motor just isn’t going to appear to accomplish like a thing with 401 horsepower and 464 pound-toes of torque must. It can be not significantly punchy all-around town, and merging onto the highway requires lengthier than predicted, the silky and astute 6-pace computerized transmission accomplishing its very best to assistance get this rig up to pace. I blame the Sierra’s towering body, mammoth frontal spot and prepared-for-motion weight of 7,418 kilos for this pokey effectiveness. Drivers who want far more capability and self-assurance (or just want to roll some coal) can get a 6.6-liter Duramax diesel matched with a 10-pace gearbox, though you pay back by the nose for the privilege of burning oil. This powertrain provides about 10 grand to the truck’s cost tag.

Since the Sierra 2500’s gross auto weight rating is higher than eight,500 kilos, it is exempt from gasoline-financial state testing. Continue to, unladen, in true-planet driving, I’ve averaged all-around fourteen miles per gallon according to the trip laptop, which isn’t really as well terrible for a thing of this dimensions and weight.

The truck’s journey is definitely on the agency side, but it is not so starchy that it crashes above bumps or shatters your backbone. The journey is a touch harsher than I’d like, but this stiffness is necessary so you might be not sitting down on the bump stops when the bed’s whole of cargo. Load this GMC up with bricks, gravel or a cord or two of firewood and I wager it would journey damn close to like a Lexus. The Sierra’s steering is sluggish and imprecise, as well as it is prone to enable the truck wander a little bit, but the independent entrance suspension presents it an edge above competing heavy-responsibility trucks, which still come with good entrance axles.

This inside is boring and drab.

Large truck, very small screens

GM’s recent-technology pickups are not recognized for their stellar interiors. Silverado and Sierra cabins in each gentle- and heavy-responsibility variety are low-budget affairs created of unattractive tricky plastic. The seats are flat, and numerous of the secondary controls are of low top quality. Ram has a distinct advantage in this spot and even Ford’s older trucks are a hair nicer.

The Sierra AT4’s infotainment system with integrated navigation is straightforward to use and responsive, but it is displayed on an eight-inch touchscreen that seems to be very small on these an expansive dashboard. Further more cheapening the practical experience, this panel’s viewing angles are not good, with the hues very easily washing out.

The $7,975 AT4 High quality Bundle involves a vary of facilities these as Apple CarPlay and Android Auto that each hook up wirelessly, rear cross-traffic warn, entrance and rear parking sensors and computerized large beams. It also gets you a distinct and crisp head-up display and GMC’s Security Notify Seat, which vibrates to alert the driver of risk.

The Sierra Hd is a person difficult truck.

Consolation in this truck is combined. The 10-way electric power-adjustable driver’s chair is agency but practically totally free of any bolstering. It can be slash for another person a number of periods heavier than me. The backseat, having said that, is fairly wonderful, presenting heat for the outboard travellers and miles of legroom many thanks to the crew-taxi body.

Pony up, cowboy

In addition to that AT4 High quality Bundle, this Sierra 2500 also options vivid Cayenne Purple Tintcoat paint, a $645 possibility, as well as it is equipped with the $545 gooseneck/fifth-wheel prep possibility. Which includes $1,595 in location expenses, it checks out for $68,one hundred sixty, a steep cost to be sure, but a person that’s not totally unreasonable for the capability it gives. That determine is also in line with a comparably equipped Ram Energy Wagon or a Ford F-250 with the Tremor package.

The 2021 GMC Sierra 2500 is able and tricky-functioning. It can be a truck I can regard, even if it is a person I really don’t really like.
