The GMC Acadia--sibling to the Saturn Outlook and the Buick Enclave--has broken cover. Like those vehicles, the nearly Chevrolet Tahoe-sized Acadia seats up to eight people in three rows and is powered by a 267-hp, 3.6-liter V-6. Available features include audio controls inside the rear hatch for tailgating, a power liftgate, dual sunroofs, a sliding second row, and a head-up display. The crossover hauls up to 117 cubic feet of cargo. Sharing few panels with the Saturn and none with the Buick, the Acadia hits dealers late this year.
