At the front of the new S4 Avant, the single-frame grille and the accentuated horizontal line pattern emphasise the width. The bumper and the air inlets are distinctively contoured. Many mounted parts are painted in fine-grained matt greys, and chrome inlays emphasise specific areas.
The exterior mirror housings in aluminium rest on the edge accents, and the strongly contoured side skirts also help to convey the S4 Avant refined look. A trailing edge and spoiler that strongly pulls downward at the boot lid improve the flow of air. The rear bumper integrates a flat black honeycomb grille, and the diffuser clasp in matt aluminium silver borders both double tailpipes.
