GMC's largest crossover now has a new flagship, as the Acadia is the latest model available in the Denali Ultimate trim. It is a three-row family crossover that offers luxury where it matters most: not on the brand badge, but in the cabin and styling details inside and out. Dieffenbach GMC is proud to share the details of this exciting Acadia trim.
"Denali Ultimate represents the pinnacle of premium expression for the GMC brand, delivering an innovative mixture of stunning craftsmanship and real-world capability," says Jaclyn McQuaid, Global Vice President, Buick and GMC. "Expanding Denali Ultimate's innovative technologies and exclusive design elements to the Acadia nameplate allows us to further differentiate our mid-size offering in a highly competitive segment."
The Acadia Denali Ultimate's formula is similar to that of the Denali Ultimate on other models, which involves taking all remaining options from the Denali model and making them standard. They then made the model more distinctive outside with the Vader Chrome finish on the grille and GMC badging, along with exclusive 22-inch machined aluminum wheels with an After Midnight Metallic finish. The DRLs also feature an engaging lighting sequence when you approach. Unseen is a performance suspension tuned to provide a superior ride and handling balance, especially effective at isolating the cabin from sharp road impacts.

Most of the enhancements, however, take place in the cabin, where you immediately notice the Woodland Mahogany full leather seating with plaited contrast stitching and topographical patterns on the seatback, door trim, and map pockets, not that anyone really uses paper maps anymore. The dash is accented with Paldao wood, complete with laser-etched accents. All these premium materials can be bathed in high-quality sound from the Bose® 16-speaker Performance Series Sound System. Additional standard features for the Acadia Denali Ultimate include:
- Super Cruise hands-free driver assistance technology with a 3-year OnStar One Super Cruise plan
- Panoramic Sunroof
- 9 camera views, including smart technologies like HD Surround Vision and Rear Camera Mirror
- Configurable 8-inch diagonal Head-Up Display
- AutoSense Power Liftgate

Like all other Acadia models, the Denali Ultimate is powered by a 2.5-liter turbocharged inline-4 that produces 328 horsepower and 326 lb-ft of torque. The engine is paired with an 8-speed automatic transmission, and all-wheel drive is standard.
