The “new” S-Class is more of a refresh versus a full redesign
From this picture we can see that the headlights are a new design. They feature 3 LED bars, versus the single LED strip that the current S-Class has. Additionally, we can see the top accent of the front bumper, which also looks different than the current design.
According to the Mercedes product road-map seen below, the company calls for a facelift for the current S-Class sometime in the middle of 2017. Additionally, the facelifted S-Class will have new interior amenities and assistance systems – those assistance systems should be related to semi-autonomous driving.
The facelifted S-Class will be shown at the 2017 Shanghai Auto Show.
