Performance and Power
When it comes to heavy-duty trucks, performance is king, and the Sierra 2500 HD Denali does not disappoint. This truck is equipped with two robust engine options that give it both the power to handle the toughest jobs and the performance needed for comfortable daily driving.
New GMC Sierra 2500 HD Denali Engine Options: The new 2025 GMC Sierra 2500 HD Denali offers two engine choices that provide a range of towing and payload capabilities. The first is a 6.6-liter V8 gas engine that delivers 401 horsepower and 464 lb-ft of torque. This engine provides a reliable and powerful option for those who require a workhorse that can pull heavy loads, while still offering good fuel efficiency and a smooth ride.
For those who need even more power and towing capacity, the Sierra 2500 HD Denali is available with a 6.6-liter Duramax turbo-diesel V8 engine. This engine produces a staggering 445 horsepower and 910 lb-ft of torque, making it perfect for those who need to tow the heaviest trailers or haul large loads. When properly equipped, this engine can tow up to 18,500 pounds, which is ideal for tasks like hauling large construction equipment, RVs, or heavy trailers. The diesel engine’s torque-rich performance ensures that the Sierra 2500 HD Denali can take on even the most demanding tasks with ease.
Used GMC Sierra 2500 HD Denali Engine Options: Used GMC Sierra 2500 HD Denali trucks often come with a similar engine lineup, especially those from recent model years. Depending on the model year and specific configuration, used Sierra 2500 HD Denali trucks can feature either the 6.6-liter gas V8 or the 6.6-liter Duramax diesel engine. While the power output may vary slightly in older models, the performance remains impressive across the board. If you opt for a used model, you can still expect excellent towing capacity and engine reliability, especially if the truck has been well-maintained.
Towing and Payload Capacity
One of the defining features of any heavy-duty truck is its towing and payload capacity, and the GMC Sierra 2500 HD Denali excels in both categories. Whether you're looking for a new or used model, this truck is engineered to handle the toughest tasks without breaking a sweat.
New GMC Sierra 2500 HD Denali Towing & Payload: The new Sierra 2500 HD Denali is an excellent choice for those who need top-tier towing and hauling capabilities. With the Duramax turbo-diesel engine, the Sierra 2500 HD Denali is capable of towing up to 18,500 pounds with a gooseneck or fifth-wheel trailer, and up to 14,500 pounds with a conventional trailer. This is more than enough capacity to tow large trailers, boats, or construction equipment. The truck also offers impressive payload capacity, with up to 3,600 pounds of cargo space available in the bed.
For those who don’t require the full towing potential of the diesel engine, the gas-powered 6.6-liter V8 still offers substantial towing capacity, with a maximum of 14,500 pounds with a gooseneck or fifth-wheel setup and 16,000 pounds with a conventional trailer.
Used GMC Sierra 2500 HD Denali Towing & Payload: Used models of the Sierra 2500 HD Denali can offer similarly impressive towing and payload capacities, particularly from the 2020s. If you're considering a used model, you'll still benefit from the truck’s strong towing power, although exact numbers may vary slightly depending on the year and configuration. For example, earlier models equipped with the Duramax diesel engine can tow up to 18,000 pounds or more, while the gas engine versions usually have a slightly lower towing capacity, ranging between 14,500 pounds and 16,000 pounds depending on the setup.
No matter the model year, used GMC Sierra 2500 HD Denali trucks continue to offer exceptional towing power and versatility, making them a great option for those who need a reliable truck for demanding tasks.
Interior and Technology
The Sierra 2500 HD Denali not only shines in terms of performance, but it also offers a refined, luxurious interior. Whether you’re considering a new or used model, you’ll find that the Denali trim delivers a premium experience that’s hard to match in the heavy-duty truck segment.

Used GMC Sierra 2500 HD Denali Interior Features: Used models of the Sierra 2500 HD Denali still offer many of the same luxury features, although technology and design might be a bit dated in older models. For example, a used 2018 model might feature a 7-inch or 8-inch touchscreen, leather seating, and a premium audio system, but the exact configuration will vary depending on the model year. Regardless of the age, you can expect a high-end, comfortable interior, especially in the Denali trim, which stands out from the rest of the Sierra 2500 HD lineup with its upgraded materials and attention to detail.

Used GMC Sierra 2500 HD Denali Safety Features: Used GMC Sierra 2500 HD Denali trucks come with many of the same safety features, though the exact list may vary by model year.
