2026 GMC Acadia AT4

The 2026 GMC Acadia is a three-row midsize SUV that slots between the smaller Terrain and the full-size Yukon in GMC's lineup. It competes with the Ford Explorer, Hyundai Palisade, and Kia Telluride in the three-row family SUV segment. The turbo four delivers strong acceleration for daily driving, though the ride can feel firm on rough pavement. The cabin offers generous space for seven or eight passengers, with a large touchscreen and available second-row captain's chairs. The AT4 gives up the Denali's chrome and leather for a more rugged look with black accents and cloth seats, saving you several thousand dollars. Its 2.5L I4 makes 328 horsepower and 326 lb-ft of torque, paired with an eight-speed automatic and all-wheel drive, and it returns 21 mpg combined. The AT4 adds Hill Descent Control and a Terrain Mode in the drive selector, so it's the one to pick if you'll actually take it on dirt roads.
