The all-new Mercedes-Benz S-Class is expected to start around $100,000 -- and most models, like this S63 AMG, will likely be significantly more expensive. But soon, Mercedes will offer an even bigger and more expensive sedan. Photo credit: Mercedes-Benz

Daimler's (NASDAQOTH:DMLRY) Mercedes-Benz brand is one of the great luxury-car makers, and its S-Class has long been regarded as one of the best of its kind. For Mercedes fans, there's no question that the S-Class is the ultimate ride -- but now, Mercedes' CEO is looking to take things up another big notch.

CEO Dieter Zetsche recently confirmed that an even bigger -- and more expensive -- Mercedes sedan is set to debut by 2015. In this video, Fool contributor John Rosevear explains why a super-expensive Mercedes makes good business sense -- and how it could be a boon for the German luxury giant's bottom line.
