Meet the Cadillac XTS Platinum Concept that made its world debut at the 2010 North American International Auto Show in Detroit. Officially, the XTS is just a design study that showcases Cadillac's emerging top-of-the-line Platinum series of models, but unofficially, it previews the Detroit firm's DTS replacement in the full-size sedan segment that's pegged make its way onto the market by 2012.

eneral Motors did not say which platform the concept is based on, but judging from the XTS' wheelbase length of 111.7 inches or 2,837mm that is identical to the new Buick LaCrosse, we'd say that it rides on a modified version of the Epsilon II.
