2024 GMC Sierra 2500HD vs 2023 GMC Canyon

Sitting at the top of the Sierra’s seven available trims, the Denali Ultimate is newly added for the 2024 model year and comes with nearly every available option that can be included on this full-size truck.

The Denali Ultimate trim level is offered on both the 2500 and 3500 HD models. Each provides a higher degree of towing and payload capacity than what’s available in the standard GMC Sierra 1500. To put it bluntly, the Sierra HD models are pickup overkill for anyone simply looking to tow a couple of jet skis or haul a moderately-sized camper. The “HD” in the name stands for “Heavy Duty,” and its capabilities (and price) reflect this.

Powered exclusively by a 6.6-litre turbocharged Duramax diesel V8, the HD Denali Ultimate we test drove has a maximum towing capacity of 10,200 kilograms (22,500 pounds)—an 1,800-kilogram (4,000-pound) increase versus the 2023 model. Need to tow something along the lines of construction equipment or, say, a small island? Stepping up to the Sierra 3500 HD equates to a max tow rating of 16,550 kilograms (36,500 pounds) when using a gooseneck trailer hitch.

Okay, so the Sierra HD lineup has serious chops for getting tough tasks done. But how does it stack up against the competition? Hop aboard as we take a look at every aspect of the HD Denali Ultimate, from how it drives, to the user-friendliness of its infotainment system, trailer tech, and whether this new top-of-the-range trim is worth the price.

2023 marks the third generation of GMC's midsize pickup truck. The first-generation Canyon arrived for the 2004 model year as a replacement for the compact GMC Sonoma, and after a short hiatus a second-generation Canyon was introduced as a 2015 model. Throughout, the Canyon has been a twin of the Chevrolet Colorado, with only a few differences to distinguish the ostensibly upscale GMC from its working-class sibling. That changes for 2023.

The new Canyon is once again based on the Colorado, sharing the Chevy's body-on-frame platform, powertrain, and tech features. This time around, though, the Canyon is further distinguished from the Colorado by skipping some of the Chevy's entry-level features. That will raise the out-the-door price of a 2023 Canyon, but it's in keeping with the truck's positioning above the Colorado.

The Canyon is once again available in the base Elevation, luxury Denali, and off-road-oriented AT4 grades familiar to owners of the outgoing model. For 2023, GMC also adds a Canyon AT4X model that dials up the off-road capability. We drove it, as well as the Elevation and AT4 models, to see if this redesign is really an improvement.
