Why it stands out
The 2024 GMC Sierra 2500HD stands out as a heavy-duty truck that blends serious capability with a distinctly upscale feel. The Denali Ultimate trim is newly added for the 2024 model year and sits at the top of the Sierra’s seven available trims, bringing nearly every available option that can be included on this full-size truck. It is described as part bulldozer and part luxury penthouse, which captures the way it combines work-ready hardware with luxury trimmings.
Under the bonnet, the 2024 GMC Sierra 2500HD Denali Ultimate is powered exclusively by a 6.6-litre turbocharged Duramax diesel V8. In the test drive data, it is credited with a maximum towing capacity of 10,200 kilograms, and the truck is praised for its diesel’s excellent towing capability and strong acceleration. At the same time, the Sierra HD line is positioned as more truck than most buyers need, with the source noting that these models are overkill for anyone simply looking to tow a couple of jet skis or haul a moderately sized camper.
That capability comes with trade-offs. The test drive notes a thirst for fuel and says the truck feels barge-like when parking, while the user review summary points to limited colour choices and concerns about the gas engine’s reliability over time. Even so, the overall impression is of a highly capable, professionally finished heavy-duty pickup that appeals to buyers who want maximum towing strength and a more luxurious cabin than a typical work truck provides.
