GMC revealed the new 2013 GMC Acadia at the Chicago Auto Show on February 8, 2012. Acadia and Saturn Outlook (remember that one?) launched as 2007 models, joined in 2008 by the Buick Enclave as variants on GM's three-row crossover vehicle platform. The Chevy Traverse followed in 2009 (and the Outlook disappeared, along with Saturn). This time, Acadia again leads the pack as the first of the GM "Lambda" platform crossovers to receive a redesign. The 2013 GMC Acadia is scheduled to hit showroom floors in late 2012, with pricing and other details to be announced.
