Size and Passenger Space Size defines the primary difference between the GMC Terrain and the GMC Acadia. The compact two-row Terrain seats up to five passengers and offers 63.5 cubic feet of maximum cargo volume when you fold the rear seats flat, making it ideal for daily commutes and weekend trips. The mid-size three-row Acadia seats up to seven or eight passengers and expands to 97.5 cubic feet of maximum cargo space behind the first row. Families who regularly carry extra passengers or bulky gear will appreciate the Acadia's larger cabin. Available Trims and Features Both SUVs offer Elevation, AT4, and Denali trims, while the 2026 Acadia also adds the ultra-luxurious Denali Ultimate trim. The Terrain Elevation includes heated front seats, a heated steering wheel, a 15" diagonal Premium GMC Infotainment System touchscreen, an 11" diagonal Driver Information Center, and more than 16 standard safety and driver assistance features. The Terrain AT4 adds standard all-wheel drive, a lifted ride height, a front skid plate with a steel underbody shield, red front recovery hooks, and 17" Dark Machined aluminum wheels with all-terrain tires. At the top of the Terrain lineup, the Denali brings standard all-wheel drive, heated and ventilated front seats, heated rear outboard seats, animated headlamps and taillamps, HD Surround Vision, a Rear Camera Mirror, and 19" Midnight Silver machined-face aluminum wheels. The Acadia trims follow this same progression while scaling up luxury and convenience across three rows. Performance and Capability A 1.5L turbocharged 4-cylinder engine producing 175 horsepower powers the 2026 Terrain, pairing with a continuously variable transmission on front-wheel-drive Elevation models or an 8-speed automatic transmission with all-wheel drive. Selectable drive modes include Normal, Snow, Tow/Haul, Off-Road, and an AT4-exclusive Terrain Mode, and properly equipped all-wheel-drive models tow up to 1,500 pounds. Drivers who need greater hauling power can step up to the 2026 Acadia, which uses a 2.5L turbocharged 4-cylinder engine generating 328 horsepower and an 8-speed automatic transmission. Properly equipped, the Acadia tows up to 5,000 pounds for heavier trailers and recreational gear.
