THE A4 Avant-based RS4 can accommodate five occupants, all with a height-adjustable head restraint, three-point seatbelt and seatbelt pretensioner. The front occupants have airbags at the front, side and at head level, the latter part of a curtain airbag extending to protect rear outboard passengers. A single cup holder is provided on the dash facia. Cup recesses are found when the glovebox lid is opened, though recommended for use only when the car is stationary. Storage - and cup holders - are lacking for rear seat passengers, though the driver and front passenger have plenty of storage options.
