There are five trims in the 2022 GMC Sierra 2500HD lineup, namely Pro, SLE, SLT, AT4, and Denali. The base engine is a 401-hp 6.6-liter gas V8 coupled to a six-speed automatic transmission and with a choice of RWD or 4×4. A 445-hp 6.6-liter turbo-diesel V8 engine is also available and coupled to a ten-speed automatic transmission, also with a choice of 2WD or 4WD. Three body styles and two bed sizes are available that, in combination, determine the final configuration of the truck.
The base Pro trim comes as standard with 17-inch steel wheels, default black for the beltline trim, mirrors, and door handles, chrome for the bumpers, and LED daytime running lights. The four-way manually adjustable front seats are covered in vinyl (cloth is optional) and further interior features include hitch guidance, and a 3.5-inch monochrome driver-information display. The infotainment system’s screen measures seven inches and includes Android Auto, Apple CarPlay, and Bluetooth streaming. Safety features include six airbags, stability control, ABS, a backup camera, and a teen-driver system.
Upgrading to the SLE adds 17-inch alloy wheels and the multi-function MultiPro tailgate with EZ Lift. On the inside, it gets carpeting, a leather-trimmed steering wheel, cruise control, a 4.2-inch color driver-information display, and a compass. The infotainment screen measures eight inches and gains SiriusXM and 4G LTE Wi-Fi capability.
The SLT trim can only be had in Double or Crew Cab, not Regular Cab, and on the outside, it additionally gets 18-inch alloy wheels, LED cargo-bed lighting, chrome for the door handles and mirrors, LED headlights, and LED fog lights. Inside, the ten-way electrically adjustable and heated outboard front seats gets perforated leather upholstery and other additional features include dual-zone climate control, a heated steering wheel, keyless open and start, remote start, hitch view, an auto-dimming rearview mirror, and an eight-inch driver-information display. The infotainment system gains wireless phone projection.
The off-road ready AT4 is available exclusively with the Crew Cab body and the 4WD drivetrain and gets the Off-Road Package that includes an Autotrac two-speed transfer case, off-road suspension, and hill-descent control as standard. Its exterior gets color-coded bumpers and door handles, a spray-on bed liner, and gloss-black mirror caps. Added luxury features include ventilated front seats, heated outboard rear seats, premium front floor liners, and a front center console.
The range-topping Denali trim also requires the Crew Cab body and 4×4, but it’s more luxurious. From the outside, it can be distinguished by its 20-inch alloy wheels, smoked-amber LED roof marker lights, and model-specific frontal treatment. Added interior features include an eight-inch driver-information display, a bed-view camera, a power-sliding rear window, full leather upholstery, a universal home remote, wireless charging, navigation, and a premium seven-speaker Bose audio system.
