The coming CLS appears to offer more of the same: the current CLS is based on the E-Class platform; the next one is expected to be built atop S-Class underpinnings. Other than bigger body with a wider track, and bolder styling to harmonize with Mercedes' current design language, not much is expected to change.

That is usually the case with iconic cars. Having invented the category of the four-door-car with a more coupe-like silhouette, Mercedes could be waiting to see what its rivals -- from Aston Martin to VW -- will bring to the segment before it makes a revolutionary move.
