Why it stands out

The 2024 GMC Sierra 3500HD is a formidable presence in the heavy-duty truck segment, blending raw power with refined luxury. Known for its unmatched towing and hauling capabilities, the Sierra 3500HD can tow up to 16,100 kilograms (35,500 pounds) when appropriately configured, making it a prime choice for serious work. Its two robust engine options include a 6.6-litre V8 capable of 401 horsepower and a Duramax turbodiesel V8 that pushes the limits with 445 hp and 910 lb-ft of torque. Moreover, the 2024 model year introduced important enhancements such as a new Denali Ultimate trim, which adds luxury features including massaging seats and a larger infotainment display.

The Sierra 3500HD has evolved to cater to modern drivers who desire both utility and comfort. With features like smart technology for towing and off-roading, it remains appealing for both commercial and personal use. However, it's worth noting that the higher-end trims can be significantly expensive, and while it outperforms many of its rivals in luxury, some competitors might still offer superior towing capacities.
