Inside, the Q9's cabin is structured around generous space and material quality. Up front, available sports seat plus variants offer ventilation and massage functions, creating what Audi describes as a lounge-like atmosphere. The interior uses Dinamica microfibre, leather and leatherette blends, and Fine Nappa leather, depending on the configuration selected. Decorative inlays include fine grain ash natural, silk beige, lime structure natural, and carbon fibre weave with basalt grey accents all chosen to minimize the use of high-gloss plastics. New colour options such as tamarind brown and stone beige broaden the customization range considerably.
Seating configurations run to either six or seven occupants. The six-seat layout places two electrically adjustable captain's chairs in the second row for a business-class feel, while the seven-seat version allows all three second-row positions to accommodate child safety seats. All seats are partially power-adjustable as standard. To simplify third-row access, the outer second-row seat slides and tilts forward electrically without folding meaning installed child seats don't need to be removed. Third-row seatbacks fold individually via electric controls, making the switch between passenger and cargo space straightforward. For Windsor families managing longer drives toward Leamington or London, that kind of flexible packaging is worth noting.
