THE station wagon body style means the potent RS4 enjoys almost all the benefits of the A4 Avant wagon, including a comfortable load height, a reasonably deep load space, a 60/40 split-fold rear seat, skiport and an integrated, retractable cargo net that creates a barrier between the luggage area and the passengers. The vertical net can be used either when the rear seat is upright or when folded down, the latter protecting the front occupants (though only when both sections of the seatback are folded) while increasing load volume from 390 litres to 1250 litres. A retractable security blind is also provided, along with four luggage tie-down hooks, a 12-volt power outlet and - courtesy of no spare wheel - a decent underfloor storage bin.
