Why it stands out

The 2020 GMC Sierra 3500HD is designed to cater to those who require a robust, reliable heavy-duty truck capable of handling substantial towing and hauling tasks. It features impressive performance with options that include a 6.6-litre Duramax turbodiesel V8 capable of generating 445 horsepower and an outstanding 910 lb-ft of torque. This allows the Sierra 3500HD to tow up to 16,100 kilograms (35,500 pounds) when equipped properly, making it a formidable contender in the heavy-duty truck segment.

Owners have expressed satisfaction with its comfort, build quality, and exceptional towing capabilities, often comparing it favourably to competitors like Ford and Ram. However, some have noted the absence of particular features such as a CD player and optimal lumbar support adjustments. The Sierra's market positioning combines rugged functionality with modern comforts, particularly evident in higher trim levels which feature luxurious interiors and advanced technology for trailering and off-roading.
