Power and Performance: Which GMC SUV Delivers More?
The 2026 Acadia takes the lead in raw output for hauling and driving confidence. A 2.5-L turbocharged engine producing 328 horsepower and 326 pound-feet of torque powers this SUV. Equipped with the standard Trailering Package, the Acadia tows up to 5,000 pounds, providing a serious advantage for drivers pulling boats, trailers, or off-road gear.
A 1.5-L turbocharged four-cylinder engine generating 175 horsepower pairs with an 8-speed automatic transmission to power the 2026 Terrain. This lighter, more nimble crossover handles everyday driving easily, leaving the heavy lifting to the larger Acadia.
Space and Seating: Room for Passengers and Cargo
GMC Acadia features excel when prioritizing passenger space. Depending on the trim, the Acadia seats up to eight passengers and offers 97.5 cubic feet of cargo volume behind the first row with the rear seats folded flat. Utilizing all three rows still yields 23.0 cubic feet of rear storage, offering excellent practicality for family road trips.
The Terrain seats up to five passengers and appeals to drivers seeking a more compact footprint without sacrificing utility. It includes 60/40 split-folding rear seats, a rear cargo underfloor storage compartment, and front center console passthrough storage to maximize available space.
Winter Capability: AWD, Drive Modes, and Cold-Weather Comfort
Both vehicles perform exceptionally as winter GMC SUVs. The Acadia features available all-wheel drive on Elevation, Denali, and Denali Ultimate trims, with standard AWD on the AT4. Its Traction Select System includes up to six distinct drive modes to manage changing snowy or mixed-terrain conditions. Denali and Denali Ultimate trims feature heated front seats and a heated steering wheel for frigid mornings.
The Terrain provides available all-wheel drive and multiple drive modes, including Snow and Off-Road. The AT4 trim incorporates a lifted ride height, a steel front underbody skid plate, red front recovery hooks, and 17" Dark Machined aluminum wheels with all-terrain tires. The available AutoSense Power Liftgate adds practical convenience when carrying winter gear.
Tech and Safety: Staying Connected and Protected
A strong suite of driver assistance tools enhances the GMC Acadia, while the Terrain matches this security with over 16 standard safety and driver assistance features. These technologies include HD Surround Vision, Blind Zone Steering Assist, Rear Cross Traffic Braking, Forward Collision Alert, Front Pedestrian and Bicyclist Braking, and IntelliBeam headlamps. A 15" diagonal Premium GMC Infotainment System keeps drivers connected.
