The A6 etron is considered to be the 'low floor' counterpart to the
Q6 etron as the vehicles share a platform and are closely related to each other. The front of the A6 consists of a body colour grille motif surrounded by a 'black mask', which helps conceal the
ADAS sensors and low mounted headlights, which are split from the daytime running lights that sit above. The rear is characterized by a light bar consisting of 450 pixels that are used to display user selectable animations or display vehicle-to-X signals. The
Sportback model has a drag coefficient of 0.21 which Audi claims is best in class at time of launch, and the
Avant has a drag coefficient of 0.24. This is achieved in part due to
air curtain vents in the front bumper, active grille flaps, smooth and flat underfloor, aerodynamically optimized wheel choices, and optional virtual side mirrors. The dashboard features a 11.9-inch
OLED screen that serves as the
digital gauge cluster mounted alongside a 14.5-inch OLED touchscreen infotainment system with integrated
ChatGPT assisted voice command system, flanked by an optional 10.9-inch passenger entertainment screen with a togglable privacy filter. An optional
augmented reality head-up display that can display navigation information and road signs is also offered. A touch capacitive control panel on the driver's side door contains controls such as headlight settings, door locking and mirror adjustments. The interior is fully leather-free and is made from some recycled materials. Surfaces such as the dashboard and door panels are upholstered in fabric with contrast stitching. An optional panoramic roof is available with a digital liquid crystal sunshade that can be closed to either front or rear is offered. A 20-speaker
Bang & Olufsen audio system with two speakers integrated into each front headrest is available. Also optional is a four-zone climate control system. The A6 comes standard with steel springs with an optional
air suspension system; the S6 comes standard with adaptive air suspension. It is also equipped with a
frunk which can be opened by placing the key fob over the front of the hood, and the rear power hatch is foot activated with a light indicating the location of the sensor. There are two charging ports, with both capable of AC charging while the driver's side is also able to DC fast charge. The A6 and S6 are capable of towing unbraked trailers, or at a 12% slope, and can carry up to on the roof.
