Inside, the E-Class in the 213 body offers as an option two high-resolution displays, each with a wide diagonal of 12.3 inches, for the first time in this segment. Under the cover of the general class, two displays look like widescreen, forming a single horizontal long display with a combination of instruments and an infotainment system. In addition, touch control buttons ("Touch Controls") on the steering wheel first appeared in the car. Like the smartphone interface, they respond to horizontal and vertical movements, allowing the driver to control the entire infotainment system using finger movements without taking his hands off the steering wheel.
