Since the Audi S8’s rear headrests don’t collapse or nest into the rear seatbacks, and because the side mirrors are on the small side for such a large car, outward visibility is not as good as it should be. Our test car had Audi’s advanced parking system, a rear-mounted camera that shows what’s behind the S8 as well as trajectory lines displaying the path the car will take, and this helped immensely when parking and reversing. Bi-xenon adaptive headlights also improve visibility by illuminating corners when negotiating turns after dark.
