2026 GMC Acadia Denali Vs. AT4: Compare Specs, Features & More

Design & Style Comparison

What sets the Acadia AT4 and Denali apart? In short – design. The AT4 boasts a more rugged, adventurous look, which is backed up by its all-terrain equipment detailed below. Its AT4-exclusive dark-accented exterior adds to this trim level's sporty demeanor, as do its stylish and functional red tow hooks. Machined aluminum wheels measuring 18 inches in diameter feature dark-painted pockets complete the look.

Moving to the next-level GMC Acadia Denali, you'll discover a luxe SUV loaded with a unique Denali-themed design. The Denali front grille and trim badging include Galvano Silver accents, and its larger 20-inch wheels have an elegant Pearl Nickel finish.

The AT4-exclusive Forest Storm interior boasts gray and dark-colored seating and cabin trim finished with Mahogany accents. In contrast, the Denali trim offers two different interior treatments: After Dark or Sheer with Very Dark Atmosphere.

One fact is for certain: these models were created with style in mind.

Interior Features & Tech

Passengers will be elated with the features and technology inside these models, making each drive entertaining. Acadia AT4 drivers and passengers are treated to standard cabin features like a Bose® Premium 12-speaker audio system and about two dozen safety and driver assistance technologies. A 15-inch GMC Infotainment System is paired with an 11-inch Driver Information Center, bringing two large digital displays to the Acadia AT4 cockpit.

Building on the cabin tech and features of the AT4, the Acadia Denali kicks it up with an 8-inch Head-Up Display, second-row one-touch folding seats, and third-row power-folding seats. Its upscale interior includes leather-upholstered seating surfaces in the first and second rows. The driver and front passenger are also treated to heated and ventilated seats in the Denali trim.

Which do you prefer: the sporty, subdued design of the Acadia AT4 interior or the high style of the Denali, with its two available cabin themes? See our GMC Acadia specials to look out for your favorite SUV.

Performance & Engine Comparison

A potent 328-horsepower turbocharged 2.5-liter engine lurks beneath the hood of both the Acadia AT4 and Denali trims. However, there's plenty that separates these editions in terms of performance. The Denali starts with front-wheel drive, and all-wheel drive is available. AWD comes standard on the AT4.

Other rugged, off-road-focused elements that enhance the Acadia AT4 SUV's all-terrain abilities include:

• Off-road tuned suspension
• Active Torque Control AWD
• Lifted ride height for greater ground clearance
• All-terrain tires wrapped around 18-inch wheels
• AT4-exclusive Terrain Mode for the Traction Select System

While the Acadia AT4 wears smaller 18-inch wheels for a more forgiving ride over rough terrain, 20-inch wheels are fitted to the Acadia Denali, giving it more curb appeal rather than off-road performance.

What Our Happy Customers Say About The GMC Acadia

Greg Mack

We negotiated the purchase of our new GMC Acadia over the phone, as well as our trade-in with our salesman, Jorge Anton, as we live on the western side of the State . He was very responsive and offered higher than expected trade-in offer which helped close the sale. The day we picked up our vehicle, Jorge was tied up with other business so he had Juan Regueiro greet us and and handle the close of the transaction. Juan was very personable and extremely knowable on set up the vehicle's functions, Onstar and MYGMC app. The dealer's finance manager, Joshua Gonzalez, had all the financing paperwork complete when we arrived and he did a great job explaining all the paperwork we signed. Overall, from start to finish we were only in the dealership for 45 minutes. This was my first time buying vehicle at Lorenzo Buick GMC. I would highly recommend them!
