Introducing the 2026 GMC Acadia AT4, now available at Seaway GM in Cornwall, Ontario—Stock #26140. With a commanding presence wrapped in a bold Riverstone Metallic finish, this all-wheel-drive mid-size SUV is your ticket to adventure across Eastern Ontario. Designed for families who demand both rugged capability and premium comfort, the Acadia AT4 is perfect for everything from weekday commutes through Ingleside to weekend road trips beyond South Lancaster.
The Riverstone Metallic paint gives this Acadia a unique, modern edge—one that stands out at the trailhead or the supermarket parking lot. Its off-road-tuned suspension, aggressive stance, and 18-inch dark machined aluminum wheels with all-terrain tires make it a natural fit for backroads near Maxville or Churchill Heights. With signature GMC LED lighting and a hands-free AutoSense liftgate, this SUV blends rugged design with everyday practicality.
Whether you're picking up kids in Casselman or loading gear for a weekend in Williamstown, the Acadia AT4 has the space and flexibility to make life easier. The three-row layout accommodates up to seven passengers comfortably, while premium interior touches like the Forest Storm theme with Mahogany accents elevate the experience. An 11-inch digital driver display, heated steering wheel, and power-adjustable front seats ensure the driver is just as pampered as the passengers. And with nearly 2,760 litres of cargo space, you’ll never have to leave anything behind.
Confidence comes standard with more than 19 advanced safety and driver-assistance features. Whether you're navigating snowy roads in Saint Isidore or cruising through Embrun on a sunny day, systems like Active Torque Control AWD and selectable drive modes keep you in control. Add in 9 HD camera views, including surround vision and a rear-camera mirror, and you’ll park and maneuver with ease anywhere from Tyotown to Winchester. Optional Super Cruise hands-free driving capability takes long drives to the next level.
Compared to other mid-size SUVs like the Ford Edge or Jeep Grand Cherokee, the 2026 Acadia AT4 holds a clear edge in tech, comfort, and versatility. With a massive 15-inch infotainment system, wireless Apple CarPlay and Android Auto, Bose 12-speaker audio, wireless charging, and tri-zone automatic climate control, it’s built to satisfy every occupant—whether you’re commuting through Morrisburg or adventuring through Moose Creek.
