Audi S6 Black Edition TDI

The S6 Avant in diesel form is one of Audi's more unusual performance estates: a 3.0-litre TDI with mild-hybrid assistance, quattro four-wheel drive and an automatic gearbox, rather than the petrol V8 of earlier S6 generations. Power is listed at 339 bhp, with 516 lb ft of torque from low revs.

This 2025-registered Black Edition has covered 12,198 miles and has had one owner. It is finished in Daytona Grey with black Valcona leather Super Sport seats and rock grey stitching, 21-inch Audi Sport wheels, carbon twill inlays, a Bang & Olufsen sound system and a 360-degree camera. Matrix LED headlights and the Virtual Cockpit are also fitted.

The page lists an MOT expiry of June 2028 and describes the car as HPI clear, with a multi-point inspection and six months of warranty included.
