Designed to Turn Heads – And Climb Hills

The 2026 Acadia AT4 doesn’t just look the part—it lives up to its aggressive styling with real capability. A lifted suspension and exclusive 18-inch dark machined aluminum wheels wrapped in all-terrain tires make it clear this isn’t your average crossover. Add in the off-road-tuned suspension and signature GMC LED headlamps, and you’ve got an SUV that’s equal parts bold and functional. Whether you’re loading up gear using the hands-free AutoSense liftgate in Alexandria or packing for a weekend escape in Williamstown, the Acadia AT4 makes a powerful first—and lasting—impression.

Inside, It’s All Comfort, Control, and Versatility

Step inside and you’ll see why the Acadia AT4 is winning over families from Winchester to St. Andrew's West. Three rows of thoughtfully configured seating accommodate up to seven passengers, and with up to 2,760 litres of cargo space, you’ve got room for it all. The Forest Storm interior theme with Mahogany accents gives it a refined touch, while the 11-inch digital driver information centre keeps you connected to your journey. From the heated steering wheel to the power-adjustable driver’s seat with lumbar support, it’s clear this SUV was designed with comfort in mind.

Built for Confidence – Every Drive, Every Season

Safety isn’t optional—it’s standard. The 2026 Acadia AT4 comes packed with over 19 advanced driver-assistance technologies, so whether you're navigating snowy backroads in Moose Creek or merging onto Highway 401 from Casselman, you're covered.

Terrain Mode and customizable drive settings mean this SUV adapts to wherever you're going—from icy mornings in Saint Isidore to muddy summer trails in Chesterville.

Why the Acadia AT4 Tops the Segment

If you’ve considered the Ford Edge or Jeep Grand Cherokee, the Acadia AT4 deserves your attention.
