GMC Sierra 2500

Editors' Review

Heavy-duty trucks are special-purpose tools designed to tow immense loads and haul mountains of stuff in all kinds of conditions. Like other HD pickups, the 2021 GMC Sierra 2500 AT4's general lack of refinement, low fuel efficiency and ponderous dynamics make living with it day to day a challenge if you don't need the vast capability it offers.

Providing a bit of extra style and off-road capability, the Sierra 2500 AT4 models feature dark chrome exterior accents, body-color bumpers and a bold grille design. The standard bright-red recovery hooks look great and should be super useful on the trail. Ensuring this truck can take you out into the wilderness, it comes with Rancho shocks, a locking rear differential and standard 18-inch wheels with Michelin all-terrain tires, though this example rolls on swanky 20-inch rims.

Bigger isn't always better

With a crew-cab body and off-road suspension, this Sierra is enormous, about a trailer hitch short of 21 feet in length, and that's with just the 82-inch, standard-length bed. Its elevated cab gives you skyscraper views of surrounding traffic and makes climbing onboard a chore. Excluding the gargantuan telescopic towing mirrors, its body is no wider than a GMC Sierra or Chevy Silverado 1500's, but this thing feels like it takes up a lane and a half, a sensation that's accentuated by its almost comically raised hood that partly obscures forward visibility and frightens pets and small children.

The Good ~ Towing and hauling capability ~ Refined powertrain ~ Ingenious tailgate

The Bad ~ Lackluster performance ~ Same old interior ~ Brash styling

The Bottom Line The GMC Sierra 2500 packs a lot of capability, but other heavy-duty trucks are easier to live with.
