2025 Audi RS6 Avant Performance Carbon Vorsprung

This 2025-registered RS6 Avant is the Performance model, which takes the familiar 4.0-litre twin-turbo V8 from 591 to 621 bhp and 850 lb-ft. Audi quotes a 174 mph top speed with the optional dynamic package, and the page lists that figure. With all-wheel drive and a Tiptronic gearbox it is a 3.4-second 0-62 car, so it is quick enough to embarrass most dedicated sports cars while still carrying a full load of luggage.

This one has covered 14,730 miles and is finished in grey. It sits in the top Vorsprung trim with the Carbon pack and adds the RS Design Pack Plus with red interior accents, red-painted RS steel brakes calipers, carbon twill inlays and 22-inch five Y-spoke wheels in black gloss turned finish. A tow bar with trailer assist is also fitted, which is unusual on an RS6 and useful if you need to tow.

Standard equipment includes electrically adjustable front seats with driver memory, the Audi smartphone interface with wireless Apple CarPlay and Android Auto, and a park assist pack with front and rear sensors. No ownership history or service record is given on the listing.
