Mercedes-Benz has released the first official first interior pictures of the upcoming 2014 S-Class. The new flagship will make its official debut on 15 May. 

The design interior is not a massive departure from the old version, but definitely it more modern and technological. On the first site we can say that everything is melting into everything.
 
The wood on the dash that continues onto the doors, the aluminum on the buttons and the leather trim seems to create a one piece dashboard. 

The new 2014 Mercedes-Benz S-Class will feature a huge 12.3 inch display, in place of the conventional analog dials.
 
The new flagship sedan also comes with an active scenting system which ionizes and cleans the air before sending into the cabin. The front seats are coming with six massaging programs while the limousine will feature reclining rear seats (43.5 degrees).
