GMC is General Motor's fastest growing brand, due in part to its crossover, the GMC Terrain, which attracts families that want the size and cargo capacity of a small SUV, but don't want or need third-row seating. To meet customer demand, it doubled production of the Terrain since 2010 and plans to lure more buyers away from competitors such as the Ford Edge--and even upsell current Chevrolet shoppers--by adding additional technology options and giving consumers bigger bang for their buck.
