Passenger & boot space
How it copes with people and clutter
Similarly to the A4, the S4 has plenty of space up front for two to sit without clashing elbows, divided by a wide arm rest in the middle. Moving onto the back seats, the S4’s width makes it more comfortable than the Mercedes-AMG C43 for rear seat passengers – you can carry three adults in the back of an S4 for longer before they’ll start complaining.
The boot in the S4 – in both the saloon and Avant – is the same as that of the A4, and more convenient to use than that of the C43 due to being squarer in shape. There’s plenty of space for a set of golf clubs or the weekly shopping without having to fold the rear seats down. These, incidentally, can be split in a handy 40/20/40 layout as opposed to the more common 60/40 arrangement found in rivals. All S4 models also get handy netted storage areas on either side of the load area.
Interior storage space is no different to the A4. You get a large stowage area under the front armrest, two cup holders in front of the gear selector and sizeable door bins that can each hold a 1.0-litre bottle.
