a significant fuss surrounding the debut of its revised trucks. In August, GMC welcomed a select group of media representatives to preview its new flagship models—the 2027 GMC Sierra 1500 AT4X and Denali Ultimate—to provide insight into the company’s vision for its premium half-ton offerings.
Our exploration was somewhat sparse on specifics, but we’ve gathered substantial information regarding GM’s intentions for its new half-tons. Key takeaways include a completely new lineup of small-block V8s, the reintroduction of the light-duty Duramax diesel, and the option of a 34-gallon fuel tank that allows the latter to exceed 900 miles of range. A quick calculation reveals that translates to 26 mpg. Quite impressive for a half-ton.
GMC is also having some fun with the interior design. The new Sierra AT4X and Denali Ultimate feature a good amount of screen space, thoughtfully divided into functional segments—the instrument panel, the center display, the HUD, and an innovative passenger screen. Let’s delve deeper.
Let’s begin with the highest tier. Denali Ultimate is GMC’s genuine top-tier model. If you plan to spend six figures on a GM half-ton, this is where you should start. The low front air dam and automatic running boards suggest the Denali Ultimate’s intended road performance. If your goal is to see if you can achieve GM’s claimed 900 miles of range on one tank of diesel, this truck is for you. If you prefer off-road capabilities, look toward the AT4X.
However, even if the Denali isn’t your top pick for off-road adventures, GMC has crafted the interior to evoke memories of all possible destinations. Topographical relief designs can be seen on several surfaces, including the leather door panels and seat upholstery.
In addition to geography-inspired designs, you’ll discover abundant premium materials, from genuine wood to polished metal. Despite the substantial screen presence, GMC has kept physical controls for numerous major operations, such as audio volume and the trailer brake controller.
And if you’re accustomed to GM including storage solutions in its interiors, the new Sierra introduces another attractive feature: The screen retracts to uncover a storage compartment. It’s not large, but it can accommodate a wallet or other small valuables. The passenger screen can also be partially folded back when not required.
The AT4X exchanges the Denali’s more refined finishes for a tougher, more adventurous vibe. The front air dam and running boards are removed to enhance the truck’s ground clearance. The wheel size is reduced, while the tires—35-inch Goodyear Wrangler Territory MTs—are upgraded to be larger and more aggressive.
This model also places greater emphasis on off-road capability and recovery. Consider the front tow hooks, for example; they are positioned horizontally instead of vertically to improve the truck’s approach angle.
Inside, the new AT4X is somewhat more understated than the Denali Ultimate. There’s still ample screen area, but the materials lean towards a sportier feel. You continue to enjoy features such as a full panoramic roof, headrest speakers, and abundant screen space (with the same physical controls found in the Denali), albeit in a slightly more rugged package.
Stay tuned for additional updates on GM’s 2027 lineup; we believe there’s more to come from this information influx.
