Discover the New 2026 GMC Acadia in O'Fallon

The 2026 GMC Acadia takes everything drivers loved about last year's redesign and elevates it with added luxury, technology, and style. Still powered by a responsive 2.5-liter turbocharged four-cylinder engine delivering 328 horsepower and 326 lb-ft of torque with an 8-speed automatic transmission, the Acadia blends power, efficiency, and capability. With a maximum towing capacity of up to 5,000 pounds, families can handle weekend getaways or recreational trailers with ease. Core trims like the Elevation, AT4, and Denali continue to anchor the lineup, but GMC has pushed the boundaries of refinement in 2026 with the arrival of an all-new premium trim.

Introducing the Acadia Denali Ultimate

The biggest upgrade for 2026 is the debut of the Denali Ultimate, a first-ever trim level that brings ultra-luxury design and technology to the Acadia family. This new flagship SUV showcases a signature Vader Chrome grille, exclusive badging, 22-inch machined aluminum wheels, and unique lighting sequences that create an unmistakable presence on the road. Inside, comfort and sophistication are unmatched thanks to heated and ventilated full-leather massaging front seats, Paldao wood trim with laser-etched detailing, embossed topographical map accents, and a panoramic sunroof. The Denali Ultimate also introduces advanced driver assistance with available Super Cruise, a Bose 16-speaker Performance Series sound system, and premium conveniences like an AutoSense power liftgate and a configurable Head-Up Display.

Upgraded Tech and Safety for Every Driver

Every 2026 GMC Acadia now benefits from more standard technology and safety features. A Rear Camera Mirror comes standard across the lineup, providing a wider, less obstructed view of the road behind. GMC has also expanded its suite of advanced driver assistance systems, offering more than 19 standard safety features on every trim. Audio technology has been updated as well, with most models now equipped with a Bose 12-speaker system, while the Denali Ultimate retains the premium 16-speaker upgrade. With these changes, the Acadia delivers not only comfort but also peace of mind on every drive.

Style, Value, and Versatility in this GMC Nameplate

GMC has also refreshed the Acadia's exterior palette, adding colors such as Glacier White Tricoat and Riverstone Metallic to help drivers customize their SUV. Pricing has risen modestly, with trims like Elevation, AT4, and Denali seeing slight adjustments to reflect the added standard equipment and upgraded features, while still remaining a strong value in the three-row SUV segment. Whether you're drawn to the rugged appeal of the AT4, the luxury of Denali, or the groundbreaking Denali Ultimate, the 2026 GMC Acadia provides a perfect blend of style, practicality, and performance for families across every lifestyle.
