: Good vehicle. Decent, but not quite the best. Often affordable, but lacking key features found in vehicles of the same class.

Overview

What's New

Following in the footsteps of the all-new GMC Sierra that bowed in 2019, the 2020 GMC Sierra 2500HD is completely redesigned for the new model year. An new 6.6-liter V8 gasoline engine and a new 10-speed automatic transmission join the truck’s powertrain lineup. The Sierra 2500HD is now offered in an off-roading trim called the AT4. GMC’s nifty six-function tailgate is newly available.

Choosing Your GMC Sierra 2500HD

The Sierra 2500HD is offered in five trims: Sierra, SLE, SLT, AT4, and Denali. Pricing starts at $37,195 including destination for the base Sierra trim and goes up to $65,295 for a base Denali.

Engine Choices

There are two available engines for the GMC Sierra 2500HD. The new gasoline 6.6-liter V8 gas engine is paired with a six-speed automatic transmission. The 6.6-liter Duramax turbodiesel V8 is paired with the all-new 10-speed automatic transmission.

Engine TypeHorsepowerTorqueMax Towing
6.6L V8401 hp464 lb-ft17,200 pounds
6.6L Turbodiesel V8445 hp910 lb-ft18,500 pounds

The turbodiesel is available on every trim, typically for a $9,890 premium over the gas engine. However, the upgrade can cost anywhere from $9,750 to $12,115 depending on the trim.

GMC also offers the turbodiesel engine with integrated power take-off (PTO) on the base Sierra and SLE trims. The PTO system costs anywhere from $995 to $1,220 depending on the configuration.

Rear-wheel drive is standard, while four-wheel drive with a new two-speed transfer case is available. Four-wheel drive is standard on AT4 and Denali models. The EPA doesn't measure the fuel economy of heavy duty trucks.

Passenger and Cargo Capacity

The Sierra 2500HD is available with a Regular Cab, Double Cab, or Crew Cab. Regular Cabs only have two doors and no rear seat, Double Cabs have two full doors in the front and two half doors in the back, while Crew Cabs have four full-size doors. The Sierra 2500HD can seat three, five, or six passengers depending on which you choose.

It's also available with two different beds: Long (8-foot-2-inches) or Standard (6-foot-10-inches). With the smaller bed option, cargo space measures in at 69.5 cubic feet, while the long bed can hold 83.5 cubic feet of cargo.

Safety Features

Standard safety features on the Sierra 2500HD are limited, but hitch guidance and General Motors' Teen Driver system are included.

Front and rear parking sensors, lane departure warning, and blind-spot monitoring are available on the Sierra, SLE, SLT, and AT4 trims as part of the $890 Driver Alert Package I.

On the SLT and AT4, a surround view camera, a bed view camera, and a 15-inch head-up display require the $2,125 Technology Package. The SLT and AT4 also make the Driver Alert Package II available for $645, which brings automatic emergency braking, forward collision warning, and lane departure warning, among other features.

The range-topping Denali trim adds automatic emergency braking, front and rear parking sensors, rear cross-traffic alert, lane departure warning, blind-spot monitoring, and forward collision warning as standard. The Technology Package is still available for $1,875.

Connectivity

Every Sierra 2500HD comes with a 7-inch touchscreen that includes Bluetooth, Apple CarPlay, Android Auto, and a USB port. SLE trims and higher are equipped with an 8-inch touchscreen, a wi-fi hot spot, and two USB ports. The SLT trim adds four more USB ports. The 8-inch touchscreen is available on the SLE.

Sierra - From $37,195

The base Sierra is a heavy-duty work truck, so it comes with things that help you focus on the job at hand. Vinyl upholstery, a tilt steering column, manual windows and door locks, air conditioning, and 17-inch steel wheels are standard.

Buyers can add some creature comforts with the Convenience Package ($1,950), which brings cruise control, remote keyless entry, power doors and windows, an EZ Lift tailgate, and more.

SLE - From $41,595

The SLE trim is the better starting point for the majority of consumers, as it brings more creature comforts. Standard features include 17-inch aluminum wheels, LED headlights, LED taillights, cloth upholstery, a leather-wrapped steering wheel, cruise control, and remote keyless entry.

Ticking the box for the SLE Convenience Package ($2,405) adds a heated steering wheel, dual-zone climate control, heated front seats, and a remote start system. For drivers that tow, the ProGrade Trailering System ($710) adds hitch guidance with hitch view, the 8-inch touchscreen, and a tailgate with EZ Lift assist.

SLT - From $52,195

A six-speaker audio system, a 10-way power driver’s seat, leather upholstery, heated front seats, a heated steering wheel, an auto-dimming rearview mirror, and 18-inch wheels are standard on the GMC Sierra 2500HD SLT. GMC’s innovative MultiPro tailgate is also included.

A wireless charger, a Bose audio system, and navigation are included in the SLT Preferred Package ($1,070).

AT4 - From $59,295

The AT4 trim is the off-road-oriented trim in the lineup. All-terrain tires, 18-inch wheels, heated exterior mirrors, red recovery hooks, and an automatic locking rear differential are standard. On the inside, the AT4 comes with heated and ventilated front seats, heated rear seats, and rear underseat storage.

Buyers can greatly enhance their truck with the AT4 Premium Package ($4,215). It includes blind-spot monitoring, rear cross-traffic alert, navigation, wireless charging, a Bose audio system, black assist steps, 20-inch black wheels, and much more.

Denali - From $65,295

Offering near luxury amenities, the Denali comes with navigation, a Bose audio system, front bucket seats, wireless charging, dual-zone climate control, 20-inch wheels, assist steps, and LED fog lights.

If you want a truck with a sunroof, tick the box for the Denali Ultimate Package ($2,870), which also includes the head-up display, surround-view camera system, and bed view camera. The sunroof is also available on its own for $995.

CarsDirect Tip

One of the main attractions with the all-new 2020 GMC Sierra 2500HD is GMC’s MultiPro tailgate, which is only standard on the SLT, AT4, and Denali. With that in mind, the SLT trim is the one we’d choose. It comes with many more creature comforts than the lower two trims, and is also available with 15 packages, which means there’s plenty of room for customization.
