Though the rear seat itself is comfortable, leg room is at a premium if taller people are riding up front, a problem exacerbated by hard front seatbacks with storage netting appended to them. As long as the forward chairs can be powered a few inches toward the dash, however, the Audi S4 can accommodate adults in the rear seat. Handy levers and buttons fold the front seatbacks and power the seats forward to aid entry and egress.
