In an exclusive pre-game release and following a behind-the-scenes version that we showed you on Friday, Mercedes-Benz has published an extended cut edition of its Super Bowl XLV commercial called 'Welcome'. With this ad, the German automaker 'welcomes' four new additions to its range including the next generation SLK roadster and CLS 63 AMG, as well as two never before seen (at least not officially) models, the SLS AMG Roadster and the C-Class Coupe. The quartet of new Mercedes-Benz cars can be seen towards the end of the video, which is posted for your viewing pleasure after the break.
