The high-performance character of the RS 4 Avant is clearly evident at first glance. The elegant exterior design is distinctively accentuated by sharp details that change the exterior dimensions compared with the volume model. The new top model in the model series is 4,719 millimeters (15.48 ft) long, 20 millimeters (0.79 in) longer than the A4 Avant. It has a width of 1,850 millimeters (6.07 ft), which is 24 millimeters (0.94 in) wider than the model on which it is based, yet its height of 1,416 millimeters (4.65 ft) is 20 millimeters (0.79 in) lower.

The hexagonal single-frame grille is set in a frame with a matt aluminum-look finish; its honeycomb insert is finished in high-gloss anthracite and adorned with an RS 4 badge. LED daytime running lights encircle the xenon plus units like a clasp in the wedge-shaped headlights with a wavy bottom edge. The air flows through large air inlets broken up by angled struts and covered with honeycomb grilles. They are integrated into a boldly contoured bumper that tapers into a splitter edge. The low center air inlet is divided into three small openings.

The side view is dominated by the chiseled side sill caps and flared wheel wells. The flared side elements with the sharp horizontal upper edges are a small tribute to that all-wheel drive pioneer from 1980, the Audi quattro. The side mirror housings and trim strips have a matt aluminum-look finish, and an extended roof spoiler with a recessed center segment increases the downforce on the rear axle.

Catching the eye at the intensively sculpted rear end of the car are the RS 4 badge and the prominent bumper. The two large, elliptical tailpipe tips of the dual exhaust system are integrated into the diffuser, which extends far upward. In the upper section of the diffuser is a honeycomb insert. If the optional matt aluminum styling package is selected, an aluminum-look contour above the insert separates the diffuser from the body. The standard LED rear lights radiate elegant light patterns.

A choice of eight colors is offered: solid Ibis White, the metallic paint finish Suzuka Gray, the pearl effect colors Daytona Gray, Misano Red, Phantom Black and Sepang Blue, and the specially pigmented crystal effect colors Panther Black and Prism Silver. Audi exclusive customized paint finishes are also available. Other elegant alternatives are the styling packages in black or matt aluminum as well as the carbon engine compartment cover.

The body of the high-performance Avant boasts high rigidity and crash safety combined with low weight. A strut brace is integrated into the front section of the car. The extensively clad underbody includes air vents for the seven-speed S tronic and the front brakes. Thanks to its advanced aerodynamics, the Audi RS 4 Avant generates downforce at high speed to further enhance stability. The cD value is 0.34; the front surface area measures 2.18 m² (23.47 sq ft).
