The most appropriate engine is the smooth 3.6-liter V6 that returned 19 mpg in our tests, which isn't a standout. A less powerful but still sound 2.5-liter four-cylinder is standard. This family-friendly three-row SUV is very quiet, the front seats are comfortable, and the infotainment system is easy to use. The outboard second-row seats can slide and tilt forward, even with a child seat in place. But many luxury features, such as four-way adjustable lumbar, a power sunroof shade, and auto-up windows, are missing even on our high-end Denali version. Available safety features include forward-collision warning with automatic braking, pedestrian detection, and blind-spot monitoring.

These combine to form a smooth and refined powertrain, though the transmission is sometimes reluctant to downshift. Later versions have improved transmission tuning. Expect about 16 mpg overall. The Acadia is available with front- or all-wheel drive. The ride is comfortable, handling is responsive and the interior is quiet. The third-row seats are roomy enough to accommodate three adults, especially when the second row is moved forward. A 2013 redesign brought an upgraded interior with an improved infotainment system and a new center airbag between the front seats.
