WheelBase is pleased to present this spectacular Audi S6 Avant 4.0 TFSI V8 Black Edition, which offers a truly unique opportunity for the performance enthusiast. This particular example has been expertly transformed into a formidable super-estate, featuring over £5,000 of high-end upgrades. The mechanical heart of this vehicle is a Stage 2 remap, proven on a dyno to produce nearly 600BHP, with the soundtrack provided by a premium Milltek exhaust system. The exterior aesthetic is equally impressive, sitting on striking Rotiform wheels and further enhanced by a full Maxton Design bodykit, giving it a road presence that rivals its RS6 sibling. As a Black Edition model, this S6 benefits from a sinister factory aesthetic, including high-gloss black styling accents that perfectly complement the custom upgrades. Practicality remains a core strength of this V8 powerhouse, featuring Audi's legendary quattro all-wheel drive and the lightning-fast S tronic transmission. Inside, the cabin is a masterclass in luxury, equipped with the BOSE Surround Sound System, dual-zone climate control, and MMI Navigation Plus. The generous Avant boot space ensures that despite its supercar-slaying performance, it remains a highly versatile vehicle for everyday family life. The Audi S6 Black Edition stands out as a rare find, especially with such high-calibre and documented modifications. The combination of its 600BHP V8 engine, premium Rotiform alloys, and massive estate utility makes it a highly capable and standout choice. This particular S6 offers a compelling package of raw, dyno-proven power and refined German engineering, all backed by a comprehensive performance history.
