2023 GMC Sierra HD In Flagstaff, AZ

If you're searching for a heavy-duty pickup truck suitable for every occasion, consider the 2023 GMC Sierra HD. In addition to its incredible capabilities, the Sierra HD has a dynamic design ideal for city streets and rugged trails. You can also take advantage of a spacious cabin full of innovative amenities and cutting-edge safety features.

Trim Levels

With the 2023 Sierra HD lineup, you have five trims to select from, including the Pro, which has an aggressive yet elegant stance enhanced by LED headlights, taillights, and daytime running lights. GMC's MultiPro tailgate, the industry's first six-function tailgate, is available for the Pro and is standard on the SLE. On the SLE, you'll also find aluminum wheels measuring 17 inches and featuring a machined finish. The SLT's aluminum wheels measure 18 inches and have dark gray metallic pockets.

The AT4 is available with gloss-black aluminum wheels measuring 20 inches. You can also outfit this model with an X31 Off-Road Package featuring twin-tube Rancho shocks and skid plates. The top trim, the Denali, features polished wheels measuring 20 inches and featuring an eye-catching multidimensional design. Each trim in the Sierra HD lineup is available as a 2500 or 3500.

Engine

The 2023 Sierra HD comes equipped with a 401-horsepower 6.6-liter gas V-8 engine that generates 464 pound-feet of torque. If you prefer a diesel-powered pickup, you can outfit your Sierra HD with a 445-horsepower 6.6-liter Duramax turbo-diesel engine that puts out 910 pound-feet of torque. When properly equipped, the Sierra HD 2500 can tow 18,510 pounds. A properly equipped Sierra HD 3500 has a maximum towing capacity of 36,000 pounds.

Performance

If you select a Sierra HD with the gas V-8, your truck will also feature a six-speed automatic transmission with an overdrive gear for smooth, efficient operation, a tow/haul mode, and auto-grade braking. GMC pairs the turbo-diesel V-8 with a 10-speed Allison transmission that delivers seamless, straightforward acceleration and handling. The Sierra HD comes standard with an agile rear-wheel-drive system, or you can equip your pickup with an all-wheel drive for maximum control and stability in challenging conditions.

Interior

The 2023 Sierra HD is available with three- and six-seater cabs, with both configurations featuring comfy and easy-to-clean seating surfaces. Available amenities include a 10-way power driver's seat with lumbar support, heating for both front seats, and a heated steering wheel. You can also take advantage of a premium GMC Infotainment System featuring built-in navigation and an 8-inch diagonal color touch-screen.

Safety Features

The 2023 GMC Sierra HD is available with several intuitive safety features, including a lane-departure warning that helps you avoid unintentional drifting and parking sensors that assist with squeezing in and out of tight spaces. A following-distance indicator lets you stay mindful of tailgating, while a lane-change alert tells you if a vehicle is blocking your path when trying to change lanes. You'll appreciate GMC's teen driver technology if you have a new driver in your family. This innovative system monitors your teen's driving when you can't be in the vehicle with them and encourages better driving habits.
