The redrawn exterior of the Audi A4 Avant TDI bears all the hallmarks of the current Audi design language - with sporty accents. A slit below the hood is reminiscent of the brand icon, the original Audi quattro. Silver frames structure the large air inlets that are filled with honeycomb grilles. The TDI models are equipped with LED headlights as standard. When viewed from the side, the silver exterior mirror housings and the strongly contoured sill trims - also silver - are particularly eye-catching. On the roof of the Audi A4 Avant TDI, the aluminum-look rails and the long spoiler create accents. With the Sedan, the spoiler is integrated into the luggage compartment lid.

At the rear, LED lights with dynamic indicators come as standard. The large diffuser in matt dark chrome with a silver trim contains a honeycomb insert. Ribs subdivide its lower section, which frames the four chrome-plated exhaust tailpipes. S badges adorn the outer skin and the illuminated door sill trims. Paint finishes in Daytona gray, quantum gray and turbo blue are reserved for the S models (as well as the S line exterior).
