Below we report the low-res version of these sketches, that show a design combining some of the surface elements of the new S-Class with a number of sporty elements such as the front grille.
The proportions are characterized by a very low stance, with a set-back cabin, an arched roof-line and tight, dynamic character lines running along the flanks.
The rear end features horizontal tail-lamps, a somewhat new element that recalls the design of the 2010 F800 Style Concept.
