GM announced today that a new XTS luxury sedan is in the works, heralding the return of the American "boat." The XTS will be built in Oshawa, Ontario, and  will be based on the XTS Platinum Concept. It will be available in front (lame) and all-wheel drive

On a note more interesting to us proleteriat, there will also be a new compact sedan dubbed the ATS (pictured above). Cadillac specifically mentions the BMW 3-Series, Mercedes C-class, and the Audi A4. It has apparently been benchmarked on the 3-series as well, so we are very excited to see what the General is cooking. 

Both will be available in 2012.
