Mercedes-Benz S-Class range already includes the Saloon in standard and long-wheelbase length, as well as the sporty coupe.
Three more variants are to follow soon and include most likely the Maybach, Pullman and Cabrio.
We have seen the longer Pullman variant testing before and here we have the official patent pictures from the United States Patent and Trademark Office.
There are no big surprises having seen the prototype on the road before. The S-Class Pullman is reportedly 6.4 metres in length, boasting a 2+2+2 seating arrangement with the four seats in the passenger part facing each other, separated from the driver with a privacy glass. Keywords here are comfortable individual seats and high spec entertainment with internet connectivity, different screens and superb audio.
An armoured version is also in development, weighing reportedly up to 5,300kg and costing around £750k.
