Both the Sierra 1500 and Sierra Heavy Duty get trailering tech upgrades for the new model year, says autoevolution.com’s Aurel Niculescu. GMC has added on the following four technologies to make towing easier and safer for owners: Bed Hitch Guidance, Cargo Bed Zoom View, Trailer Length Indicator, and Jack-Knife Alert.

The automaker has also tweaked two functions found on the outgoing model year. The Rear Side View function now displays both sides of the truck and trailer, when the truck is moving forward or backward. Rear Trailer View now comes with guidelines and a Trailer-Angle Indicator feature.

The 2021 Sierra introduces a handful of fresh options for customizing the cosmetics and powertrain. The Sierra HD has an available Denali Black Diamond Edition that includes powered steps and 20-inch high-gloss black wheels. The brand has added an off-road step to the Sierra 1500 AT4 trim for enhanced practicality. You can also get your Sierra in two new paint colors — and save $1,500 off the purchase price when you choose the 3.0-liter Duramax turbodiesel engine.

One of the most obvious changes about the 201 Yukon is that it gets a new AT4 trim for off-roading enthusiasts, as Car and Driver confirms. This variant comes with four-wheel drive, red tow hooks and skid plates, all-terrain tires, and a two-speed transfer case. It even has an available Air Ride Adaptive Suspension system that lets you adjust the vehicle’s height by up to 2 inches to improve ground clearance.

The 2021 Yukon and Yukon XL are also bigger than the previous year’s models. Per GM, the Yukon model is approximately six inches longer than before and has a wheelbase nearly 5 inches wider than the 2020 version. This translates to 30 percent more maximum cargo volume. The Yukon XL has a wheelbase that’s approximately 4 inches wider and is about 1 inch longer. This means 23 more cubic feet of cargo volume than the 2020 version.

GMC has also enhanced the Denali trim for 2021. According to the automaker, the Yukon Denali now has a unique interior. You can choose from four exclusive color themes that incorporate hand-stitched leather and genuine wood surfaces. Distinctive seating and a refined instrument panel elevate the cabin. Outside, the Denali gets a bigger and bolder Galvano chrome grille and LED lighting for a contemporary aesthetic.

The 2021 Terrain now has an AT4 trim to satisfy adventurous, outdoorsy fans of the model. Per GMC, this version comes equipped with a 5.3-liter V8 and 10-speed automatic transmission. It has Dynamic Fuel Management technology and a Traction Select System to enhance efficiency and performance. A rugged facade — with a black chrome grille and cladding on wheel arches and doors, modern LED headlights, and AT4 badges — complements its athletic performance.
