The dark-toned interior welcomes the driver and passengers with illuminated door sills bearing exclusive S logos. Contrasting stitching on the leather steering wheel and sport seats conveys a dynamic and elegant ambiance. The S sport seats in leather and Alcantara can be upgraded to fine Nappa leather with rhombus pattern and a pneumatic massage function. Brushed aluminum inlays are standard, with elegant wood applications or an exclusive carbon inlay available as options. The shift paddles on the steering wheel sport an aluminum-look finish; there are stainless steel applications on the pedals and footrest.

The optional rear seat bench plus in the new Audi SQ5 TDI is split into three segments. Longitudinal and seat back angle adjustment are optional. The luggage compartment has a basic capacity of 550 liters (19.4 cu ft), which can be increased to 1,55sss0 liters (54.7 cu ft) by folding down the rear seat backrests.
