If you’re about to flip a coin between these two family SUVs, just keep in mind that the GMC Acadia is the bigger of the two. She stretches 193.6” overall, stands 66” tall, is 75.4” at her widest point, and offers the cruising confidence of a 112.5” wheelbase. Step inside and enjoy up to 142 cubic feet of passenger volume, which can make for a very comfortable ride in Glen Burnie, MD.
