Comfort and Convenience
The on-board computer reports running data such as consumption and range on a display, but it only informs. Setting cabin temperature stays with the single-zone climate control, which regulates air itself.
Safety and Driver Assistance
The passenger airbag protects only in a crash that has already begun, inflating from the dashboard. The electronic stability program works earlier, braking individual wheels to keep the car on its intended line.
Multimedia and Connectivity
The audio system handles playback itself: it decodes the signal, drives the speakers and holds the volume and source controls, while the AUX input simply feeds an external player's sound into it.
