Why it stands out

The 2023 GMC Sierra 3500HD is a standout in the heavy-duty truck segment, combining robust performance with a touch of luxury. It offers a range of powerful engine options, including a 6.6-litre V8 and a Duramax turbodiesel, which provide exceptional towing capacities—up to 16,100 kilograms (35,500 pounds) when properly equipped. The Sierra 3500HD is designed for serious work, yet it doesn't skimp on comfort and technology, especially in higher trims like the Denali, which features premium materials and advanced infotainment systems. While it excels in capability, potential buyers should be aware that its larger size can make it unwieldy in tight spaces, and top trims can be quite expensive. Overall, the 2023 model continues to uphold GMC's reputation for durability and refinement in the heavy-duty truck market.
