2021 GMC Sierra 2500HD Review: A Truck You Can Trust

The GMC Sierra 2500HD keeps one of America's greatest traditions of building awesome big trucks alive and well. The sheer dimensions and weight of one of these full-size pickups will make Prius drivers cower in fear. Last year saw the 2500HD undergo a complete redesign to keep it in the running against competitors such as the Ram 2500, and the good news is that it still feels fresh. Under the hood, the 2500HD packs your choice of V8 gas or diesel engines, with the 6.6-liter turbodiesel V8 producing a massive 445 horsepower and 910 lb-ft of torque. Power is sent to the rear or all four wheels via a ten-speed automatic transmission with this Duramax powerplant or a six-speeder with the V8 gas engine. With a wide number of bed and cab configurations on offer and numerous packages, the 2021 GMC Sierra 2500HD is a well-rounded truck that can stick with the best of them.

2021 Sierra 2500HD Exterior

If the sheer size of the 2021 GMC Sierra 2500HD does not impress you, its bold fascia and beefy bodywork will. Looking at the competition, the Ram 2500 has a more controversial face, while the Chevy Silverado 2500HD is possibly the most aggressive of the bunch. Exterior features on the base GMC are sparse but include 17-inch steel wheels and LED daytime running lights. Higher up in the range, the SLT gains 18-inch alloy wheels while the Denali rolls on 20-inch polished alloys. The SLT includes cargo bed LED lighting and if you go for at least the SLE, you'll get GMC's MultiPro tailgate. The AT4 features high gloss black mirror caps, and the Denali gets a polished exhaust tip and smoked amber LED roof marker lamps, amongst others.

Dimensions

The Sierra 2500HD is a big vehicle in any configuration. The smallest of the bunch is the Regular Cab with the long bed, which measures at 235.5 inches in length. The longest is the Crew Cab with a long bed, which measures 266.09 inches in length. The overall width of this truck ranges between 81.75 and 81.85 inches, while the overall height varies between 79.65 and 79.95 inches, depending on the model.

The front track on all models is 68.1 inches while the rear track is 68.3 inches. Max ground clearance is just over ten inches. The lightest truck on offer is the gas-powered Regular Cab with a curb weight of 6,105 pounds. On the other side of the spectrum, the Crew Cab with the diesel engine, 4WD, and the long bed weighs as much as 7,886 lbs.

  • Length 235.5 in
  • Wheelbase 141.6 in
  • Height 79.9 in
  • Max Width 81.8 in

Exterior Colors

A big and bold truck deserves a big and bold color palette, and GMC does not disappoint in this regard. The base model can be finished in your choice of six colors, with Summit White being the only no-cost option. The other five colors on offer cost $495 each and include Cardinal Red, Onyx Black, Pacific Blue Metallic, Quicksilver Metallic, and Brownstone Metallic. The SLE adds Ebony Twilight Metallic and Cayenne Red Tintcoat, the latter being a pricier $645. The SLT can be painted with a White Frost Tricoat for an additional $1,095, though the AT4 doesn't get the same option. The Denali gets exclusive access to Hunter Metallic and Carbon Black Metallic, both of which carry the same $495 charge. However, this model loses the Brownstone shade. The AT4 has its own limitations as well as. For instance, it isn't compatible with Carbon Black or Cardinal Red.

2021 GMC Sierra 2500HD Performance

Those looking to buy full-size trucks will mostly care about factors such as towing capacities, load capacities, and torque figures, and the GMC Sierra 2500HD offers plenty of each. Under the hood, you get the option of a 6.6-liter gas V8 or a 6.6-liter turbodiesel V8. The former produces 401 hp and 464 lb-ft of torque, while the latter churns out 445 hp and 910 lb-ft. The Sierra 2500HD can be configured in RWD or 4x4 guise. No matter what engine you go for, the GMC Sierra offers excellent performance, but those looking for a serious working truck will prefer the massive torque output of the 6.6-liter turbodiesel engine. The performance figures are impressive: independent testing has shown that the diesel will manage a best 0-60 mph sprint in under seven seconds and under 20 seconds when pulling a trailer weighing 18,000 pounds. The maximum towing capacity is 18,500 lbs for diesel-engine Crew Cab trucks, but gooseneck trailering ups that to 18,510 lbs for the diesel 2WD model in Regular Cab form. The maximum payload capacity is 3,979 lbs, which applies to the 2WD Regular Cab with the gas engine.

Engine and Transmission

GMC doesn't beat around the bush when it comes to power, and you won't find any 4-cylinder engines here. Under the hood of the 2021 GMC Sierra 2500HD, it's strictly V8 power. The 6.6-liter V8 gas engine was first introduced in 2020 and produces a healthy 401 hp and 464 lb-ft of torque. Power is sent to the rear or all four wheels via a heavy-duty, electronically controlled six-speed automatic transmission. This engine does a convincing job of hauling this large truck around town, and you'll never be left wanting for power, but you'll be left with the nagging reminder that there is a more powerful option on the table. The 6.6-liter turbodiesel V8 engine is the one to go for if you want all the power and bragging rights. With 445 hp and a mammoth 910 lb-ft of torque on offer, this engine makes short work of heavy trailers, and thanks to a silky 10-speed auto transmission, the diesel boasts smooth, hassle-free power delivery. Either way, both power plants are up to the task.

Handling and Driving Impressions

Full-size trucks have come a long way in terms of drive comfort and handling ability, and the GMC Sierra 2500HD is up there with the best of them thanks to its use of an independent front suspension. Not only does this little party trick make the ride more comfortable than ever before, but it also helps the truck feel more eager to turn in and more maneuverable in general. This is great for city driving but also helps a ton when taking on the great outdoors. When it comes to towing, it is amazing how comfortable the 2500HD is; this truck will make an excellent long distance cruiser. It helps that both V8 options barely feel strained when hauling a trailer on the open road.

Off-road, the 2500HD is a capable machine but can be a bit big for tight trails. The AT4 trim adds all-terrain tires and a two-speed transfer case, as well as an off-road-tuned suspension for increased capability, and it pays off. The exhaust brake function is highly effective at keeping the brakes from overcooking.

2021 GMC Sierra 2500HD Gas Mileage

The EPA does not provide any official gas mileage figures for most large, heavy-duty trucks like the GMC but don't get your hopes up: these engines will both offer pretty lousy fuel economy, especially when fully loaded. However, there are a few real-world consumption reports that give an idea of what to expect. With the diesel engine, 2021 trucks were found to return an average figure of around 14.5 mpg. The V8 gas engine, however, returned a heavier number of 11.5 mpg. Based on these figures and the various tank capacities on offer, the range you get will vary quite dramatically. For instance, a Regular Cab with the diesel engine has a 28-gallon tank, so it could, theoretically, achieve around 406 miles. However, all cab styles with the gas engine have a standard 36-gallon tank so can travel for around 414 miles between visits to the pumps, using the assumed figures. Double Cab and Crew Cab derivatives with the diesel engine also have access to a 36-gallon tank and these models will have the best range of around 522 miles. Fuel economy will vary greatly depending on your driving style and how loaded the vehicle is, of course.

2021 GMC Sierra 2500HD Interior

Last year's redesign did wonders for the Sierra 2500HD's appeal: it's an attractive truck to look at, but unfortunately, the same cannot be said for the inside of the cabin. The design seems rudimentary and out of date when compared to rivals from Ford and Ram, and the choice of materials isn't that impressive either. Denali models do an excellent job of lifting the cabin with plusher materials, but the design remains an issue. Thankfully, there's a lot of interior space to thrash about in disappointment. In base form, this is a simple working truck that offers vinyl seats and manual windows, but the higher up you go, premium features such as rear-seat infotainment and navigation become available.

Seating and Interior Space

From the three-seater Regular Cab to Double and Crew Cabs with two rows, this big truck offers ample space and can accommodate up to six people depending on cab style. The AT4 and Denali reduce the usual six seats to five due to their sporty bucket-style seats. The 2021 GMC Sierra 2500HD offers a generous 43.11 inches of headroom in the Regular Cab, while Double and Crew Cabs drop that figure to 43.03 in the front. Legroom is also generous at 44.53 inches in front for all cab styles, while the Crew Cab provides a massive 43.4 inches of legroom for back seat passengers. The standard seats are well-padded and will find preference with those who rack up lots of miles. The driving position is high-set, which aids in forward visibility. SLT models and upward gain ten-way power-adjustable front seats.

  • Front Leg Room 44.5 in

Interior Colors and Materials

The 2500HD is a hard-working truck, especially in base trim, so it makes sense that GMC has gone with hard-wearing materials instead of a more premium choice. The base model is as basic as it comes and is fitted with a choice of Jet Black cloth or vinyl seats and a rubberized vinyl floor covering. This setup should last the working man a good few years. The SLE adds a bit of comfort in the form of standard carpeted flooring and a leather-wrapped steering wheel. It also adds Dark Walnut/Slate to the color palette, drops vinyl as a material choice. The SLT gets perforated, leather-appointed front outboard seats, and front and rear carpeted floor mats. The AT4 has premium floor liners, and the top of the range Denali gets its own unique Forge perforated leather upholstery. Color choices are rather limited. For example, the entry-level model and AT only offer Jet Black, while the SLE and SLT add Dark Walnut/Slate as an option. The Kalahari accents of the AT4 add a bit more flair to the environment, and the Denali gets exclusive access to the Dark Walnut/Dark Ash Grey combination.

2021 GMC Sierra 2500HD Truck Trunk and Cargo Space

The entire point of buying the GMC Sierra 2500HD is to gain access to the bed in the back. GMC offers the 2021 truck with two bed lengths, namely the standard and long beds. The standard supplies a sizable 69.5 cubic feet of space. If you're after more space, the long bed (which is 16 inches longer) provides 83.5 cubic feet of space.

Inside, small-item storage depends on which cab style is selected, but all include cupholders and a glovebox. Some cab styles have under-seat storage in the front and rear, and some have large center console storage units. Crew Cab models in the lower trims get a 60/40-split folding rear seat.

2021 GMC Sierra 2500HD Infotainment and Features

Features

Five models make up the range, but as we found in prior reviews, don't expect anything spectacular at the lower end. The base-model Sierra comes with only the basics such as manually adjustable vinyl/cloth seats, a 3.5-inch diagonal monochromatic driver information display, single-zone climate control, a rearview camera, and dual USB ports. The SLE adds features such as cruise control, cloth seats, a leather steering wheel, a compass, and a 4.2-inch digital cluster. The mid-range SLT's specs are more impressive and include a 10-way power driver seat with power lumbar support, leather upholstery, heated front seats, dual-zone automatic climate control, hitch guidance with hitch view, and remote start. The off-road AT4 adds features such as front bucket seats with ventilation, heated rear outboard seats, and a front center console. The range-topping Denali includes an eight-inch digital driver info center, a bed-view camera, HD surround vision, a universal home remote, and wireless charging. A 15-inch diagonal multi-color head-up display is available optionally.

Infotainment

The infotainment system has become a critical selling point for most modern vehicles, even heavy-duty trucks, so it is disappointing to find a small seven-inch touchscreen display in the base model Sierra 2500HD. At least the system is quick to respond to inputs. The base system comes with Bluetooth streaming, an AM/FM radio, a six-speaker sound system, and Android Auto and Apple CarPlay integration. However, the base Regular Cab makes do with only two speakers. The SLE adds 4G LTE Wi-Fi compatibility and SiriusXM radio. The SLT gets a larger eight-inch display with wireless phone projection, SiriusXM 360 L, and voice-activated technology. The top-of-the-range Denali adds navigation and a seven-speaker premium Bose sound system that does a much better job of playing back your favorite tunes.

2021 GMC Sierra 2500HD Problems and Reliability

The 2021 GMC Sierra 2500HD has so far been subject to two recalls based on the NHTSA's records and both had to do with the seat belts. In both cases, occupants may not be properly restrained in an accident. This could be due to either a seat belt bracket that isn't secured or, in the case of the more recent recall, incorrect bolts used to attach the belts. One of these issues carried over from 2020, which saw five recalls issued for the truck. These recalls included unsecured front seatbelts, defective roof-rail airbags, two recalls for an unsecured hood that may open unexpectedly, and seatbelt pre-tensioner issues.

GMC covers the Sierra 2500HD with a three-year/36,000-mile warranty, a five-year/100,000-mile powertrain/drivetrain warranty on diesel engines or for the same time period but just 60,000 miles in the case of the gas engine. A one-year/one visit maintenance plan and a five-year/60,000-mile roadside assistance plan are also included. For the latter plan, the coverage extends to 100,000 miles in the case of the diesel model.

2021 GMC Sierra 2500HD Safety

For now, no 2021 GMC Sierra 2500HD crashworthiness review has been published by the NHTSA or the IIHS. However, the previous-generation 2019 model did score four out of five stars on the NHTSA rating system. Considering that safety standards are always improving, we expect that the newer 2020 and 2021 Sierra should improve on this score. The smaller GMC Sierra 1500 has been tested by the IIHS and mainly received Good ratings in all crashworthiness categories (besides the Marginal small overlap passenger-side test) so, once again, the 2500HD is likely to be quite a safe truck.

Key Safety Features

The Sierra 2500HD's biggest safety system is its sheer size, but GMC has added basics like six airbags, including seat-mounted side-impact airbags for the driver and front passenger,

StabiliTrak, electronic stability control, a rearview camera, and Teen Driver for every model. SLE models add OnStar and GMC Connected Services, and the SLT includes an HD rear vision camera along with hitch guidance with hitch view. The Denali is the only model that comes with active driver-assistance tech such as automatic emergency braking, forward collision alert, front and rear park assist, lane change alert with side blind zone alert, lane departure warning, and rear cross-traffic alert. An HD surround vision camera system is standard on the Denali as well. These features are offered as optional extras on lower models.

Verdict: 🏁Is the 2021 GMC Sierra 2500HD a good truck?

GMC plays open cards with buyers: the 2021 GMC Sierra 2500HD is a no-nonsense truck that gets the job done. In base form, the features list is short, and the interior basic, but the moving parts under the skin are well-engineered and hard-wearing. The two engine options help this truck haul competitive loads and offer good power, albeit at the cost of fuel economy. On the road, the 2500HD drives surprisingly well, and with good available trailering tech, this pickup is the perfect work partner. Those looking for a more refined experience will have to deal with a notable price increase, especially when going for the top-of-the-range Denali. Pay the extra money, and you do get a fair share of premium features and standard driver assistance features. The 2500HD is a solid truck. Our only wish was that GMC did something to freshen up the dated interior, but other than that, it's a solid choice.

🚘What's the Price of the 2021 GMC Sierra 2500HD?

The price of the GMC Sierra 2500HD lineup starts at $36,200 for the Sierra 2WD Regular Cab Long Bed. This price excludes registration, taxes, and a destination fee of $1,695. This is followed by the SLE at $41,600 and the SLT at $51,600, though the latter entails upgrading to the Double Can and settling for the standard bed. Once you start looking at Crew Cab configurations, the AT4 becomes available at $59,100, but this also means equipping the 4x4 drivetrain. The same is true for the range-topping Denali, which starts at $65,500. These prices all represent the trims in their most affordable form.

Being a truck, the price per trim will rise based on a number of factors. For example, the base Sierra is $2,800 pricier in 4x4 guise. Other trims can also be upgraded to 4x4 although the AT4 and Denali are 4x4 by default. Elsewhere in the lineup, the most affordable SLT will cost $9,890 more if you upgrade to the Duramax turbodiesel engine. Different bed lengths will also influence the price - it simply depends on the type of truck you need.

2021 GMC Sierra 2500HD Models

There are five trim levels to choose from, starting with the Sierra, followed by the SLE, SLT, AT4, and finally the Denali. The 2021 Sierra 2500 HD is offered with a 6.6-liter V8 engine and six-speed automatic transmission in RWD or 4x4, but a 6.6-liter turbo diesel V8 with a ten-speed automatic transmission is also available. Two bed sizes and three body styles are used to determine the final configuration.

The base model features steel wheels, manually adjustable vinyl/cloth seats, single-zone climate control, hitch guidance, and Apple CarPlay and Android Auto with a seven-inch touchscreen display.

The SLE adds features such as cloth seats, remote keyless entry, cruise control, a compass, a larger 4.2-inch driver display, and a leather steering wheel.

The SLT isn't compatible with the Regular Cab body style and can only be had as a Double or Crew Cab. This trim level includes 10-way power-adjustable front seats with heating, a heated steering wheel, dual-zone climate control, an HD rearview camera system, keyless open and start, remote start, an auto-dimming mirror, a larger eight-inch infotainment display, and wireless phone projection.

The AT4 is the first trim that is limited to the 4x4 drivetrain and the Crew Cab body style. It comes with ventilated front bucket seats, a front center console, heated rear outboard seats, premium front floor liners, and for increased off-road capability, adds an Autotrac two-speed transfer case, hill descent control, and off-road suspension.

Denali models are also limited to 4x4 and the Crew Cab but with a more luxurious edge. They have features such as navigation, a seven-speaker Bose premium sound system, a bed-view camera, an HD surround vision system, a power sliding rear window with rear defogger, wireless charging, and driver assistance features such as lane change alert with side blind zone alert, lane departure warning, and rear cross-traffic alert.

Additional Packages

Trucks need to cater to a variety of needs so there are numerous packages to choose from. However, prices aren't always what they seem and some initially appealing packages can only be bundled together with other expensive extras.

Starting with the base model, the Sierra is offered with the $1,950 Convenience Package, which adds features such as remote keyless entry, cruise control, an EZ lift power lock and release tailgate, tinted glass, and LED cargo bed lighting. The $1,365 Gooseneck package adds a spray-on bed liner, an integrated trailer brake controller, and a bed-mounted 7-pin trailer harness but requires buyers to select other supporting options for a grand total of $3,315. On the 4x4 version of the base Regular Cab, GMC offers a $525 X31 Off-Road package for outdoor enthusiasts which includes upgraded suspension, hill descent control, skid plates, and 17-inch all-terrain Blackwall tires.

The cheapest, Regular Cab SLE is eligible for packages such as the SLE Convenience package, which adds a 10-way power driver's seat, keyless open and start, and remote start for $2,255. The $685 Preferred Package costs $685 on the Regular Cab, and adds SiriusXM with 360L, wireless phone charging, and an eight-inch premium infotainment display, but other cab styles require many other extras, pushing the price of this package up..

Higher up in the lineup, AT4 models are offered with the $7,975 AT4 Premium Plus Package, which includes features such as a power sunroof, rear camera mirror, safety alert seat, the premium Bose sound system, the Driver Alert Package, and HD surround vision. Denali models can be kitted out with the $2,990 Denali Black Diamond Edition, which adds premium floor liners, power side steps, an upgraded sound system by Kicker, black 20-inch alloy wheels, a head-up display, and more, but requires one to go for the Duramax diesel engine and other options, pushing the overall additional cost to over $15,000.

🚗What 2021 GMC Sierra 2500HD Model Should I Buy?

With so many trims, cab, and bed lengths to choose from, there truly is something for everyone. If you're looking for a comfortable daily workhorse, we would suggest going with the 2WD SLE with the optional 6.6-liter turbodiesel engine. This truck not only sports 910 lb-ft of torque but gets added luxuries such as cruise control, remote keyless entry, cloth seats, a leather steering wheel, and a 4.2-inch driver info display. If you're more of a family man, then the Double Cab, Regular Bed SLT should be perfect. This truck offers ample cargo space and premium features such as leather power seats, dual-zone climate control, and wireless phone charging. We'd suggest getting the optional driver aids, too.

2021 GMC Sierra 2500HD vs GMC Sierra 1500

GMC offers a massive range of trucks for all occasions and requirements, and the 1500 is the smaller brother that is just as hardy but costs less. The GMC 1500 starts at just over $30,000 but is still a solid performer with a maximum towing capacity of 11,800 pounds. Unfortunately, it doesn't offer the same power but does get a powerful 3.0-liter Duramax diesel engine with 460 lb-ft of torque. It's the more economical truck thanks to its lighter weight and smaller engines. On the inside, these trucks both offer the same look and feel and spacious cabins. The 1500 is perfect for the person who needs a rugged truck, but not necessarily all the pulling power of the 6.6-liter diesel in the 2500. Which one is best, though, will depend on just how much heavy lifting you need to do.

2021 GMC Sierra 2500HD vs Chevrolet Silverado 2500HD

The choice here will, in most cases, boil down to brand loyalty, seeing as both the 2021 GMC Sierra 2500HD and the Chevrolet Silverado 2500HD share the same underpinnings and engines. The bad news for the GMC is that the Chevy is nearly $1,000 cheaper. The significant difference here is the look of each pickup. We prefer the blunt and aggressive look of the Chevrolet, although personal tastes will vary considerably and many don't love the Chevy for exactly the same reason. On the inside, the GMC surprises by offering better interior quality, and the GMC MultiPro tailgate is also a big plus. But neither of these will really sway Chevy loyalists away from the brand, and vice versa.
