The Chicago Auto Show has always sort of been known as a truck show, and because of that, many new pickups, SUVs and crossovers tend to debut in the Windy City. That in mind, it comes as no surprise to learn that General Motors plans to debut an all-new version of the GMC Acadia in Chicago next month. The Acadia, which launched in 2006 as a 2007 model, is indeed due for an overhaul, with its only major update being the addition of a Denali model (pictured) in 2011.

If you recall, the Acadia was the first of the Lambda crossovers to go on sale, alongside the now-departed Saturn Outlook. When asked about the possibility of a new Chevrolet Traverse or Buick Enclave making an appearance in Chicago, GMC Communications Manager Joe LaMuraglia stated that it "will be a GMC show," leading us to believe that we'll have to wait until New York or even Los Angeles to see the rest of the Lambda portfolio.

No specific details about the new Acadia were revealed at this time, nor was there any hint as to whether we'll see just the standard CUV or whether it will be joined by a Denali version. Stay tuned for the full details next month.

UPDATE: A source confirmed to Autoblog that GMC will debut a mid-cycle update of the Acadia at the Chicago Auto Show next month, not an all-new design. Expect an updated interior design and exterior tweaks.
