2023 Audi S6 Avant Black Edition

The 2023 Audi S6 Avant Black Edition makes a compelling case as a fast estate: 339 bhp from a 3.0-litre TDI V6, 700 lb-ft of torque, and quattro all-wheel drive combining to deliver a 5.1-second 0-62 mph time with the kind of effortless long-range pace the diesel architecture excels at. At just 16,214 miles from new, this is effectively an unworn example in a desirable blue finish, compliant with Euro 6 emissions standards and with much of its usable life ahead.

Black Edition specification sharpens the standard S6's appearance with darkened exterior trim elements, while the two optional packs — Comfort and Sound, and Parking Assist — extend an already well-equipped interior. Four-zone climate control, Audi Smartphone Interface with both Android Auto and Apple CarPlay, front and rear parking sensors with a reversing camera, and LED headlights with high beam assist are all present. The result is a cabin that works as well on a daily commute as on a cross-country run.

The S6 Avant occupies a specific niche: the performance estate that doesn't advertise itself. With a 155 mph top speed and the pulling power to make motorway progress almost contemptuous, it undercuts comparable petrol alternatives on running costs while remaining firmly in performance estate territory. A clean example at this mileage in the current market represents genuine value.
