The 2025 Audi RS6 Avant is a high-performance luxury wagon powered by a 4.0-liter twin-turbocharged V8 producing 621 horsepower and 627 lb-ft of torque. It accelerates from 0-60 mph in just 3.3 seconds with launch control, while its sport-tuned adaptive air suspension and rear-wheel steering deliver remarkable agility for a wagon of its size. With its cavernous cargo area, aggressive widebody stance, and RS-specific interior appointments, the RS6 Avant is the ultimate do-everything performance machine.
