Comfort and Convenience
The on-board computer displays information rather than controlling it. Consumption or range readings can be cycled and reset, but the underlying behaviour, such as the single-zone climate setting, is changed on its own controls.
Safety and Driver Assistance
The driver's airbag acts only once a collision is under way, cushioning the impact against the wheel. Electronic stability program works earlier, trimming engine torque and braking wheels to keep the car on its intended line.
Multimedia and Connectivity
The audio system handles the final analogue stage: it decodes or receives a source, amplifies the resulting signal and drives the speakers, whether the content arrives over Bluetooth or through the AUX input.
