GMC Sierra 2500HD at Medlin Buick GMC

When it comes to heavy-duty trucks that are ready for just about any modern hauling and towing need, the GMC Sierra 2500HD is an excellent model to consider. The latest model year of the GMC Sierra 2500HD makes gas and diesel engines available along with five trim levels. The full GMC Sierra 2500HD trim lineup consists of the Pro, SLE, SLT, AT4, and Denali.


The GMC Sierra 2500HD packs plenty of power under the hood regardless of the trim selected. The standard Pro level trim comes equipped with a brawny 6.6-liter V8 that makes 401 horsepower and 464 pound-feet of torque. This engine pairs with a 6-speed automatic transmission. Rear-wheel drive is standard while four-wheel drive is an optional upgrade. If you're more interested in a diesel engine, then the Sierra 2500HD offers up a 6.6-liter diesel V8 that makes 445 horsepower and 910 pound-feet of torque. This engine works with a 10-speed automatic transmission. The AT4 trim provides drivers with an off-road-ready trim that comes with underbody skidplates, hill descent control, standard four-wheel drive, and an off-road suspension. There's also an optional X31 off-road package that can be had, which offers up an upgraded suspension, skidplates, and hill descent control.


The heavy-duty truck doesn't skimp when it comes to tech thanks to a robust set of standard and optional features. The Pro trim comes equipped with a 7-inch touchscreen display, Apple CarPlay/Android Auto, USB ports, and a 6-speaker audio system. The SLE trim steps up tech offerings by replacing the standard infotainment display with an 8-inch display while also adding satellite radio and a Wi-Fi hotspot. The SLT trim adds a 120-volt power outlet along with rear USB ports and a high-definition backup camera. The Denali is far and away the most amply equipped in terms of tech, offering up a Bose premium audio system, a navigation system and an upgraded driver infotainment display. Optional tech features include a head-up display and a digital rearview mirror.

Interior & Exterior Features

Staying comfy while taking on tough tasks can be a breeze thanks to an extensive selection of comfort and convenience features. The Pro trim comes equipped with vinyl seating surfaces, air conditioning, and manual doors/windows. Moving to the SLE trim adds cloth seats, carpeted floors, and remote keyless entry. The SLT makes some major upgrades by adding dual-zone automatic climate control, leather upholstery, heated front seats, a heated steering wheel, and a power adjustable driver's seat. The Denali trim touts the most robust set of interior features thanks to offerings like wood/aluminum interior trim, a power sliding rear window, and premium leather seats.

Exterior features abound with the Sierra 2500HD. The Pro trim comes with a locking tailgate, a trailering hitch, and an integrated rear bumper with steps on each corner. The SLE trim comes with upgraded exterior trim along with a MultiPro configurable tailgate with EZ lift assist, and 17-inch alloy wheels. The SLT gains all-terrain tires, upgraded headlights/taillights, LED foglights, LED Cargo bed lighting, and power folding trailering mirrors. Stepping to the AT4 trim adds recovery hooks, body color bumpers, and spray-in bedliner.
