2018 Acadia

The GMC Acadia is a full-size crossover that can seat up to seven passengers. Like many vehicles in GM's portfolio, the Acadia has been the focus of a right-sizing movement that has produced a leaner, meaner crossover.


GMC offers its new crossover in three flavors—Acadia, Acadia All Terrain and Acadia Denali. The first is your garden-variety crossover presenting a blend of all-weather capability and passenger/cargo practicality. The second, as its name suggests, is an off-road-centric model which prioritizes ground clearance and 4X4 flexibility. The last is GMC's luxury line and offers all the comfort features you could possibly want in an entry-premium three-row CUV.

In its most basic form, the new Acadia is 700 pounds lighter than the car it replaces. Don't let that number fool you, however; this is still a large, spacious SUV.

The Acadia's updated styling represents a pretty significant departure from the old look. Up front, the bug-eyed headlamps are gone, replaced by slimmer, LED-lined housings. The squared-off, three-slot grille is also gone, replaced by a vaguely octagonal piece that blends nicely with the slimmer, more elongated shape of the new SUV.

Inside, you'll find a center stack topped by a touchscreen boasting a surround that mirrors the octagonal theme of the grille. Housed here are all the connectivity features you've come to expect, including OnStar with 4G LTE and a WiFi hotspot.

Moving back, you have your choice of either a two-seat second row with captain's chairs or a three-seat bench. Behind that is an optional third row.

The GMC Acadia offers a new feature called "Rear Seat Reminder." This system exists to keep distracted parents from accidentally abandoning their children in the back seat. If you open the rear doors before getting into the car and driving off, a chime will sound when you next shut the car off and open your door. This chime is accompanied by a message in the main cluster that says, "Check Rear Seat."

Under the hood you'll find one of two engines—a 2.5L four-cylinder or a 3.6L V6. The four-pot produces 193 horsepower and 188lb-ft of torque; the six is good for 310 horsepower and 271lb-ft. Both engines are available in standard front-wheel-drive configurations or with optional all-wheel-drive and are mated to six-speed automatic transmissions.

The four-cylinder is rated at 21 MPG city and 26 highway with front-wheel-drive; all-wheel-drive drops that to 21/25. With the six, you should expect 18 MPG in the city and 25 on the highway no matter which drivetrain configuration you opt for.

With the smaller footprint comes a little less capability as a trade-off for reduced weight and added efficiency. With the third row up, 12.8 cubic feet of cargo space is available in the rear. With the third row folded, that bumps up to 41.7 cubic feet. Fold the second row down too and you max out at 79 cubes. V6 models are also rated to tow 4,000lbs.
