The 2023 GMC Sierra 3500 HD is a powerful and capable heavy-duty truck with rugged styling. The large truck stands out because it does not compromise on comfort despite its incredible engine performance and towing capacity. At Capital GMC Buick, we are thrilled to soon feature the 2023 Sierra 3500 HD in its many trims at our dealership in Edmonton, Alberta, upon its official launch. Here's what you can expect!

2023 Sierra 3500HD Performance

The Pro trim has a six-speed automatic transmission and a 6.6-litre V8 gas engine, producing 464 lb-ft of torque and 401 horsepower. The higher trims have a ten-speed automatic transmission and a 6.6-litre V8 turbo-diesel engine producing an incredible 910 lb-ft of torque and 445 horsepower. The engines are powerful, responsive, and efficient, with a maximum towing capacity of 36,000 pounds and a payload capacity of 3,715 pounds. The Denali and At4 trims have independent front suspensions that deliver excellent handling, ride comfort, and wheel alignment. A cooling fan helps keep the turbo-diesel engine at the optimum temperature to maximize horsepower and improve performance. There's also an off-road package that offers an automatic rear locking differential, underbody skid plates, twin-tube shocks, and off-road suspension.

2023 Sierra 3500HD Exterior

The enormous exterior of the Sierra HD asserts dominance on the road and makes it a towing champion. The large truck comes with a six-function multi-pro tailgate, and the premium Denali trim has chrome front recovery hooks, a dual path air induction system, chrome handles, mirrors, and six-inch chrome assist steps. All trims come with lower convex and trailering mirrors that can either automatically or annually be retracted and extended. A standard side bed step allows you to carry luggage from the cargo bed easily.

2023 Sierra 3500HD Interior

The truck's cabin is expansive and refined with well-placed user-friendly technology. Some interior features you can find on the trims include dual-zone climate control, ventilated and heated front leather seats, and a leather-wrapped steering wheel. The driver's seat is elevated to give a better view of the road and comes with cushions to keep you comfortable during long journeys. Crew cab models have lots of leg room for rear passengers to enjoy the ride. Various interior colour options give the truck a sophisticated look and feel, and plenty of storage space is available, including under-seat storage, centre console storage, and lower and upper glove boxes.
