Mercedes-Benz does a lot things really well in their vehicles, but like many automakers, the infotainment system is pointed out as a problem time and time again. So Mercedes-Benz has taken another run at their infotainment interface.
The changes are revealed in the interior of the new 2017 E-class. This model comes with 3 different infotainment and instrument display packages. The base version has dual-circular instruments flanking a 7.0-inch display that sits in front of the driver. There is also a 8.4-inch display that is in the middle of the dash.
Upgrade one level and you keep the conventional looking instrument cluster, but are rewarded with a center display that grow s to 12.3-inches.
The top-of-the-line option gets rid of the fixed instruments and replaces them with a second 12.3-inch display, "creating a an ultra-widescreen display like that of the S-class, although there are still a few hard buttons on the center stack for the HVAC controls."
The other big change is the addition of new touchpads. This gives you three ways to control the main infotainment screen: steering wheel pad, center touchpad, and scroll wheel.
