GMC has unveiled the new 2013 Acadia and Acadia Denali at the Chicago Auto Show.

First impressions are everything, and the 2013 Acadia was developed to make a strong one. A chiseled, three-bar grille sits prominently in the new, more upright design.

Diffused LED running lamps lend a premium look to the Acadia and are standard on all models, regardless of whether standard projector beam or optional HID headlamps are selected. New taillamp detailing reflects the advancements up front.

The new Acadia gets other subtle exterior design updates, including wrap-around rear glass and a new rear spoiler. New 18-, 19- and 20-inch wheel patterns complement the vehicleâ??s lines and stance.

The Acadiaâ??s refined interior uses upgraded soft-touch materials, with French stitching that adds a tailored look and red ambient light flowing across the dashboard. SLT and Denali models get aluminum accents on the center console, doors and dash.
