With space for two and their luggage, but not much more, the A5, S5 and RS5 are the perfect weekend jaunt companions, though they're equally well-suited to the daily grind--just don't plan on carting around three or four passengers most of the time.
The front-seat emphasis in the cabin is obvious; even base models have comfortable, roomy seats that are well-bolstered and relaxing. Upgrade to one of the sportier models and you'll gain bolsters and spirited-driving security without giving up much of the comfort. Leather upholstery is found throughout the A5's seating range, with RS5 models gaining a choice of Alcantara or Nappa leather.
Head and leg room is generally good in the front row, though coupe models fitted with the panoramic sunroof can compromise head room for taller drivers.
In the back seat, you'll find what amounts to occasional seating for two. Due to the two-door configuration, getting in and out of the rear seats can be difficult, despite the long doors. Very little leg room and head room is available, making the space inappropriate for most adults for more than a few minutes. The Cabriolet cuts this rear-seat space even further, leaving it suitable for children, at best.
The trunk is fairly large in Coupe models, with 16.3 cubic feet of space; Cabriolets lose some storage for the soft top, cutting cargo volume to 11.3 cubic feet. The rear seats fold down to help make room for larger parcels and offer front-seat access to the trunk.
Materials, throughout the range, are high-quality and solid-feeling. Surfaces gleam with a satin luster, and the blend of leather, wood, metal, and plastic is masterfully executed, especially in the RS5, where stainless steel and carbon fiber trim are available.
