Why it stands out

The 2023 GMC Sierra 3500HD stands out as a heavy-duty pickup built around serious towing and hauling ability, while still offering a wide range of cab, bed, axle, and trim combinations. It can be configured as a regular cab, extended cab, or crew cab, with either a short bed or a long bed, and buyers can choose between single- and dual-wheel rear axles. That flexibility is part of its appeal: the Sierra 3500HD can be tailored from a basic work truck into a far more upscale and feature-rich machine.

For 2023, the Sierra 3500HD offered two engines: a 6.6-litre V8 with 401 horsepower and 464 pound-feet of torque, or a 6.6-litre Duramax turbodiesel V8 with 445 hp and 910 lb-ft of torque. Properly equipped, it could haul as much as 3,375 kilograms and tow up to 16,100 kilograms, and those figures required the diesel engine, a single cab body, rear-wheel drive, a gooseneck hitch, and dual rear wheels. The truck also brought useful towing technology and a strong feature spread, including a seven-inch infotainment touchscreen with Apple CarPlay and Android Auto on the base model, plus available trailering aids, off-road hardware on the AT4, and luxury touches on the Denali such as premium leather, a wireless phone charger, and parking proximity sensors.

Its strengths are clear: impressive capability, smart towing tech, and higher trims that make a heavy-duty truck feel more refined. The trade-offs are just as clear. The Sierra 3500HD can be unwieldy in parking lots, top trims can be prohibitively expensive, and rivals typically can tow more. Even so, for buyers who want a highly configurable one-ton truck with genuine work credentials and a more polished feel than a bare-bones hauler, the 2023 GMC Sierra 3500HD is distinctive.
