Overview

The GMC Sierra HD is all-new for 2020, with updated powertrains and a fresh exterior and interior design.

Which Sierra 2500 is the Best?

The 2020 GMC Sierra HD is a serious truck with impressive capabilities. It arrives at a time when the competition is fierce and advantages are hard-won. Once you calculate your towing and hauling requirements and your desire for advanced and luxury features, you can see which HD truck suits your particular needs. It would be a heavy-duty job to make a bad choice in this class. Find a 2020 GMC Sierra 2500 for sale or Find a 2020 GMC Sierra 3500 for sale

How Much Does a 2020 GMC Sierra 2500 Cost?

The Sierra HD comes with a naturally aspirated (non-turbocharged) 6.6-liter V8 engine with direct gasoline injection. The engine is tuned to produce 401 horsepower and 464 lb-ft of torque. A 6.6-liter V8 Duramax turbodiesel engine is also available ($9,750 to $9,890). It uses common-rail direct fuel injection to churn out 445 hp and 910 lb-ft of torque. Rear-wheel drive is standard, and 4-wheel drive is available and even standard on the AT4 and the Denali.

Gas models get a Hydra-Matic 6-speed automatic transmission, while diesel models get a new 10-speed Allison automatic transmission. Configurations include the Regular Cab, the Double Cab and the Crew Cab (standard on the AT4 and the Denali). There is also the option of a standard bed or a long bed for an additional $200. Single rear wheels are standard on 2500 and 3500 models, and dual rear wheels are available on the 3500 models. Wheel sizes range from 17 inches to 20 inches, depending on the trim level. The front suspension is short-long-arms independent with torsion bars, while the rear suspension is a solid axle with a 3-stage, multi-leaf spring setup. Steering is hydraulic power-assisted and recirculating-ball-type with optional digital steering assistance. Four-wheel disc brakes with anti-lock braking systems (ABS) are standard.

Exterior features include LED daytime running lamps, headlamps and taillamps. LED fog lamps are also available. Both bed sizes include cargo-bed-side steps, integrated CornerSteps in the rear bumper and 12 fixed tie-down points. The 6-function MultiPro tailgate is available on the Sierra HD and the SLE HD, and standard on the SLT HD, the AT4 HD and the Denali HD.

GMC focused on the new AT4 HD trim level and the Denali HD at the launch event we attended in Jackson Hole, Wyoming. The AT4, a trim level which debuted on the Class 2A 2019 Sierra last year, is an off-road-capable model that comes with specific enhancements, including an off-road suspension with Rancho Shocks, skid plates and an Eaton locking rear differential, 18-in wheels (with 20-in wheels available) all-terrain tires, a traction control system (TCS) with off-road mode, hill-descent control and hill-start assistance, a 15-in heads-up display with an off-road Inclinometer, and an HD Surround Vision camera views for low-speed looks at terrain.

The interior gets a darkened trim on the steering wheel, center stack and sill plates and a Jet Black color scheme with Kalahari accents and live stitching. The seating is leather appointed with mini perforated inserts and embroidered AT4 badging on the headrests as well as all-weather floor liners. The exterior gets AT4 badging, dark chrome exterior finishes, front and rear bumpers in the body color, a rugged textured grille in black chrome finish and red vertical recovery hooks. Standard technology features include the ProGrade Trailering System, Onstar, 4G LTE Wi-Fi, SiriusXM Radio, USB ports, keyless open and start, remote start, and rear-seat reminder.

Optional packages include the $4,215 AT4 Premium Package, which comes with a universal home remote, a rear power-sliding mirror, a GMC Premium Infotainment System with navigation, an 8-in HD color touchscreen, voice recognition, Bluetooth audio streaming, Apple CarPlay and Android Auto, Bose Premium Sound, wireless charging, LED roof marker lights, front and rear parking assist, lane-change alerting with side blind-zone alerting, rear cross-traffic alerting, 20-in wheels and black assist steps. The $2,125 Technology Package includes HD Surround Vision, a rear camera mirror, a bed-view camera, a multi-color head-up display, and a multi-color 8-in digital driver information center.

Denali HD models come with the whole bag of chips -- with practically every box checked. Still, you can add the Denali Ultimate Package ($2,870) to add HD Surround Vision, a rear camera mirror, a bed-view camera, a multicolor heads-up display and a power sunroof.

Safety

Is the 2020 GMC Sierra 2500 a Safe Car?

Driving a big pickup truck can lend a sense of security and safety, but it's important to remember that all that mass can be deadly in encounters with vehicles, pedestrians and animals. ABS, TCS, Stabilitrak with trailer-sway control and hill-start assist, airbags, and teen-driver mode are standard. Additional safety and driver assistance systems are available on most trim levels and standard on the Denali. One example is the Driver Alert Package I, which comes with front and rear parking assist, lane-change alerting with side blind-zone alert, and rear cross-traffic alert. There is also Driver Alert Package II, which includes forward-collision warning, lane-departure warning, automatic emergency braking, Intellibeam headlamps, a following-distance Indicator, and a safety-alert seat.

Competition

2020 GMC Sierra 2500 vs the competition

2019 Ford Super Duty - Starting at $33,150, the Super Duty got a complete makeover for 2019 and offers some stiff competition for the Sierra HD.

2019 Ram HD - Starting at $33,645, the Ram HD also got a redesign for 2019 and may have the nicest interior of the bunch.

2020 Chevrolet Silverado HD - Starting at $36,500 and riding on the same platform as the Sierra HD, the Silverado has many of the same available features and benefits but no MultiPro tailgate yet.
