The up-scale interior features four individual seats, immersed in a light environment which uses natural materials like leather and cork and a brown and beige colour schem.

The main innovation is the 'Reverse' seat which offers individual seating positions facing, or with one’s back to, the direction of travel, maximum spaciousness and comfort.

Four persons sit in the conventional way facing the direction of travel.

If the front passenger seat is unoccupied, at the push of a button the right rear seat can be moved to a relax position. To do this one moves the front passenger seat forward and folds the backrest towards the dashboard.

A new type of mechanism allows the passenger to sit in reverse direction and look out the back. He can chat face to face with his neighbor, work, rest, or enjoy the audiovisual entertainment.

A monitor with an overall diagonal display measurement of 51 cm and a surround sound system create a cinema atmosphere.

The “SERVO-HMI” operating concept adopts a display with a reduced number of controls and a simple and self-explanatory menu structure.

The driver can “discuss” more complex inputs, such as a destination for navigation purposes, in dialogue with an avatar, a virtual operating assistant.

The virtual assistant enters into verbal dialogue with the driver, asking for the desired destination in the navigation menu, for example, and confirming the voice input. It works the same way when you select someone to call from the phonebook or a desired radio station.

The displays of the information and control system are visible at the point farthest forward in the interior, but, optically, appear a bit further away, because at the bottom edge of the windshield there is a mirror; the display itself is horizontally retracted into the cockpit.

In this way, the need for the eyes to adapt their range for far and near vision is appreciably smaller, thus reducing eye fatigue.

Operation of the navigation system, the communication systems and the telephone as well as the audio and entertainment systems is by means of the proven COMAND rotary/pushbutton controller, to which a slide function has been added. Preselections in the operating menu are made in three positions. The air conditioning system is operated by an additional touch-sensitive control.
