GMC unveiled the new 2013 Acadia and Acadia Denali at the Chicago Auto Show, highlighting a new exterior and safety features including the industry's first front center air bag.
Acadia, which launched in 2007 as GMC's first crossover and defined a segment that has since surged in popularity, had the best sales in its five-year history in 2011. The Denali model, added in mid-2010, broadened Acadia's appeal to luxury customers with its combination of functionality and style.
