The interior of the new RS Q8 features a deliberately clean design. All elements beneath the black cloth headlining have a logical connection and harmonize with one another. The headlining is optionally available in lunar silver cloth, Alcantara lunar silver or Alcantara black. The slim instrument panel and the strongly horizontal lines convey a feeling of spaciousness. The central element in the cockpit is the top MMI touch response display. With its black-panel look, it almost dissolves into a large, black surface when switched off.

Another primary design element is the wide, symmetrical console of the center tunnel. Framing it are design elements in Aluminum Race, anthracite, which underscore the sporty character of the large SUV coupe.

Special RS displays in the Audi virtual cockpit and MMI display provide information on such things as tire pressure, torque, output, temperature, lap times and g-forces. The shift light display prompts the driver to upshift when the rev limit is reached. The optional head-up display also offers several RS-specific graphics.
