This Is the Dark Horse: RS 6 Avant Mythos Black Performance Review

The 2025 Audi RS 6 Avant Performance is more than just a high-performance wagon. It is a statement of power, luxury, and practicality wrapped in a body that is both aggressive and refined. Finished in Mythos Black Metallic, this model takes on a sinister presence, enhanced by its wide stance, blacked-out details, and signature RS design cues. It may look subtle to the untrained eye, but one press of the throttle quickly reveals that this machine means business.

Under the hood, it houses a 4.0-liter twin-turbocharged V8 engine with a mild-hybrid system that delivers a whopping 621 horsepower and 627 pound-feet of torque. That is 30 more horsepower and 37 more pound-feet than the previous RS 6 Avant. The power is sent to all four wheels via Audi’s Quattro all-wheel drive system and an 8-speed Tiptronic automatic transmission. The result is a 0 to 60 miles per hour sprint in approximately 3.3 seconds. That is performance you would expect from a supercar, not a family hauler.

But the RS 6 Avant Performance does not stop there. It also features four-wheel steering for tighter turns and greater high-speed stability, a sport rear differential that can shuffle torque between the rear wheels, and massive carbon ceramic brakes for enhanced stopping power. The drive modes are tuned to give you everything from comfortable cruising in Comfort mode to full-blown aggression in RS mode.

Inside, it is a blend of track-ready function and upscale luxury. The RS sport seats are trimmed in Valcona leather with honeycomb stitching and offer ventilation and massage. You also get a 12.3-inch digital cockpit, a dual-touchscreen MMI system, and optional packages like the RS Design Plus that adds Alcantara and blue contrast stitching. The cargo space is more than 30 cubic feet with the seats up, and over 59 cubic feet with the seats down, giving it real-world practicality that most performance cars can only dream of.

Mythos Black Metallic gives the car an extra edge. It absorbs light and makes the wide-body design even more intimidating. Paired with the Matte Carbon and Black Optic package, which adds matte black 22-inch wheels and dark trim, it transforms this wagon into a stealthy beast.

On the road, the RS 6 Avant Performance is surprisingly comfortable. Audi’s adaptive air suspension irons out most bumps while still offering the stiffness you need for spirited driving. The exhaust note is deep, refined, and exhilarating—especially when you toggle into RS mode and open up the valves. It is a daily driver that rewards you with supercar thrills without the usual compromises.

Audi has also packed this car with safety and tech features. From a head-up display and surround view cameras to adaptive cruise control and lane assist, it is built to handle real life with as much ease as it handles a backroad.

For those looking for a performance car that can handle weekend getaways, spirited canyon runs, and school runs all in one package, the 2025 Audi RS 6 Avant Performance is hard to beat. It blends brutal power, refined tech, everyday usability, and pure excitement in a way that few vehicles can match.
