GM showing off future Cadillacs

On Tuesday, GM is expected to make some future product announcements. Today, however, they are showing off some new Cadillacs to 'social media' types in hopes of generating some buzz. First off - the Cadillac ATS is the new 3-series fighter that will come in both sedan and coupe forms. Secondly - the XTS is the name of the STS/DTS replacement we've been hearing about. It is possible GM could show off one or both of these on Tuesday at their 8am EDT press conference. Stay tuned for details.
