Comfort and Convenience
The on-board computer matters mid-journey: it draws fuel consumption, range and trip distance from vehicle sensors, so a refuelling stop can be judged while still moving.
Safety and Driver Assistance
The passenger airbag protects only in an impact, inflating from the dashboard, whereas ESP works continuously beforehand, braking individual wheels to hold the intended line.
Multimedia and Connectivity
A Hi-Fi audio system separates frequencies across dedicated speakers, so quiet passages and speech stay intelligible at motorway noise levels without raising volume for every track.
