The 2024 and 2025 GMC Acadia are midsize SUVs that offer a comfortable and spacious interior, along with a variety of features and amenities. Both models are powered by a 3.6-liter V6 engine that produces 310 horsepower and 271 lb-ft of torque. However, there are some key differences between the two model years.
One of the most significant changes for the 2025 model year is the addition of a new AT4 trim level. The AT4 trim is designed for off-road enthusiasts and features a number of upgrades, including a lifted suspension, all-terrain tires, and a skid plate. Another new feature for the 2025 model year is the availability of a hands-free power liftgate. This feature allows you to open and close the liftgate without having to use your hands, which can be helpful when you’re carrying groceries or other items.
