2021 Audi RS6 Avant Carbon Black

This 2021 RS6 Avant is the Carbon Black edition of Audi Sport's family-sized hypercar-hunter, pairing the 4.0-litre twin-turbo V8's 592 bhp and 800 lb-ft with quattro all-wheel drive and a claimed 3.6-second 0-62mph time. The Carbon Black pack swaps chrome and brightwork for carbon-fibre exterior trim, giving the estate a more menacing look than the standard car.

This example has covered 39,965 miles and is finished in Daytona Grey, with a black wrap applied over the paint. Factory options include the panoramic glass sunroof, the Comfort and Sound package, and RS steel brakes with red gloss calipers. Standard equipment includes the 12.3-inch Virtual Cockpit, head-up display, wireless phone charging, four-zone climate control and HD Matrix LED headlamps with Audi laser light.

The C8 RS6 remains one of the most complete performance estates on sale, combining supercar-level pace with a large boot and everyday usability. The mild-hybrid V8 can shut down cylinders under light load, which helps cruising economy. The page lists a 155 mph top speed, the usual limited figure, though the optional Dynamic packages raise the limit higher.
