Cadillac, who once played in the field of large luxury sedans, has returned to the game with a player that rivals the Audi A6, Mercedes E-Class and BMW 5 Series. Though, its size and endless array amenities and technology also lets it scrimmage with big boys like the Lexus LS. Not only is the all-new 2013 XTS full-size sedan the first all-new vehicle launch for Cadillac since the SRX in 2009, but it adds another much needed recruit to their product roster.
