Rear Diffuser Audi A6 C7 RS6 Style 2012-2015

Audi A6 C7 RS6-style rear diffuser — the sporty presence your sedan was missing

The Audi A6 C7 rear diffuser transforms the rear of your sedan (2012-2015) with an ABS part inspired by the RS6 style. It is the element that instantly brings a sporty and premium look where the original A6 remains deliberately understated. Were you looking for the part that turns your A6 from a business sedan into a road car with a bold character, without touching the mechanics or repainting the car? It mounts under the rear bumper and changes the look of the entire rear end.

A design that transforms the rear of your Audi A6

This diffuser adopts the codes of the RS6 version and integrates perfectly into the original rear bumper. It accentuates the width and character of your sedan by creating a lower and tighter visual base. The vertical fins, the immediate signature of the RS6 C7 rear diffuser, guide the eye toward the ground and give the impression that the car is sitting lower than it actually is.

In the rearview mirror of others, the effect is immediate: an A6 equipped with a gloss black rear diffuser is no longer seen as a fleet sedan. Combined with carefully finished exhaust tips, the whole creates a coherent rear end, in the spirit of the most powerful versions of the Audi Sport range.

Material, finish and durability

Made of robust ABS, it is offered in a black or black and silver finish. The surfaces resist UV rays and the elements to retain their shine. High-density ABS has a decisive advantage in this area of the vehicle: it withstands gravel projections and light curb contacts without cracking like a low-end resin part would. The black and silver two-tone finish plays on contrast, while all-black remains the safe bet on dark bodywork.

• Faithful RS6 style — vertical fins and volume taken from the high-performance version
• Resistant ABS diffuser — resistant to UV, the elements, and road projections
• Two finishes to choose from — discreet all-black or more demonstrative black and silver
• Accentuates visual width — the rear appears closer to the ground at first glance
• Customization without work — no bodywork cutouts, no mandatory painting

Installation, compatibility and precautions

Designed for the original version of the rear bumper. A dry fit is recommended before final installation. Compatibility should be checked according to the exact version of your vehicle. In practice, the installation of a rear diffuser is done on a clean and dry bumper: present the part, identify the support points, carefully degrease the contact area, then fix it permanently. On models already equipped with an S line package, check the geometry of the bumper before ordering, as exhaust outlet cutouts may differ.

Does a rear diffuser really change the line of a sedan?

Yes, and probably more than any other exterior part at this budget. The rear of a sedan is the view most frequently offered to other road users: it is what defines the impression of width and stance. By replacing a smooth and neutral area with a sculpted volume, the Audi A6 C7 rear spoiler visually lowers the beltline and widens the ground footprint. The transformation is purely aesthetic — no aerodynamic gain is promised here — but it is immediate and perfectly reversible, unlike lowering or a complete bumper change.

Why order your Audi A6 C7 rear diffuser from Becquet Voiture?

Becquet Voiture specializes in parts that visually transform a car: spoilers, fins, diffusers, grilles, and lighting. Each reference is linked to a precise generation — here the C7 chassis in the 2012-2015 phase — and is never sold as a universal bumper blade that would just barely fit no vehicle. Our product sheets say what the part does and what it does not, our support answers in French, and our catalog is designed to create a coherent style, from front to back.
