Driving Impression

New Car Test Drive

The Acadia drives well and feels pleasantly polished, with a comfortable, composed ride and responsive handling.

Steering is nicely weighted. V6 models feel a trifle nose-heavy, but handling doesn’t suffer.

The four-wheel independent suspension readily absorbs patchy pavement. The 20-inch wheels optional on SLT (standard on Denali) can yield a stiffer ride.

Performance is modest with the four-cylinder engine. The strong V6 is an appealing choice, mating well with GMC’s 6-speed automatic.

All Terrain models look rugged, but ride comfort matches the regular Acadia. Off-pavement, it benefits from slightly revised traction-control mode.

An Acadia isn’t the most fuel-efficient crossover in its class. Four-cylinder models with front-drive are thriftiest, EPA-rated at 21/26 mpg City/Highway, or 23 mpg Combined. Adding all-wheel drive lowers the estimate just slightly, to 21/25/23 mpg.

The V6 guzzles a bit more, EPA-rated at 18/25 mpg City/Highway, or 21 mpg Combined. All-wheel drive is rated at 17/25/20 mpg. Neither engine requires premium gasoline. Four-cylinder Acadias include a Stop/Start system.

Walk Around

New Car Test Drive

Simplicity lends the Acadia its attractive appearance, with a design that doesn’t rely on curves to draw attention. Clean body lines and a masculine tone set the stage. Prior-generation Acadia owners should note that the current model is considerably smaller.

Despite the Acadia’s car-based platform, squared-off wheel openings convey a somewhat truck-like look. Large taillights on most versions are separated by a sizable chrome element.

Adding the All Terrain package cuts back on chrome, focusing on distinctive wheels and dark trim. Denali builds up the brightwork.

Interior Overview

New Car Test Drive

Largely comfortable, the Acadia cabin is clean-looking and sufficiently pleasant, if a bit bland. Though quality is evident and soft-touch materials abound, the symmetrical layout seems a bit past its prime.

Standard seating for seven includes a three-place bench in row two, plus two in the third row. Most trim levels can get optional twin captain’s chairs, reducing seating to six.

Surprisingly narrow, the Acadia cabin can feel a little cramped when filled with passengers. Front occupants can expect good views, while residing on comfortable seats. Row two is easy to access. Outboard seats are roomy, but the center position falls short on comfort. Youngsters are the best prospects for riding in the third row, which may be folded flat.

With the third row upright, cargo volume totals a modest 12.8 cubic feet. Peak capacity is 79 cubic feet.


New Car Test Drive

Riding and handling nicely, with a comfortable cabin, the Acadia is a sensible family crossover. Strong performance emanates from the available V6, but the four-cylinder trails in terms of energy. Demerits include a narrow cabin, tight third row (if installed), and limited safety technology for lower trim levels. Numerous options mean GMC has an Acadia to meet nearly any requirements.
