GMC Terrain vs. Acadia Size & Capacitie

GMC Terrain vs. Acadia Size & Capacities

The longer body and wheelbase of the 2025 GMC Acadia enables this midsize SUV to provide more cabin space and cargo capacity than the Terrain small SUV. With that added interior volume, you can seat seven or eight occupants in the Acadia, depending on the cabin configuration. The five-passenger Terrain gives you more standard cargo volume behind its back row, though. So, if you plan on keeping all seats upright when hauling groceries and other supplies, the Terrain boasts a standard 29.8 cubic feet of cargo space compared to just 23 cubic feet behind the Acadia's third row.

The Acadia is the only 2025 model in this comparison that offers an off-roading AT4 trim. In this configuration, the GMC Acadia ground clearance reaches its maximum, at 7.75 inches. The Acadia AT4 also gets standard AWD. While the 2025 GMC Terrain redesign doesn't include an AT4 trim (only the Elevation trim, for now), the 2026 model adds a Terrain AT4 option.
