This Audi RS 4 Avant Carbon Black is a beautiful example, presented in stunning condition in Mythos Black metallic, and it left the factory with over 4,600 pounds of optional equipment that most RS 4s for sale simply do not have. The big one is RS sport suspension plus with Dynamic Ride Control, the hydraulically linked damper system that transforms how the car corners and rides, and the option enthusiasts look for first. It also has the RS sport exhaust system, giving the V6 the soundtrack it deserves, and the Comfort and Sound Pack with the Bang & Olufsen 3D sound system and 360 degree cameras. Under the bonnet is the 2.9 litre twin-turbo V6 with 450PS and 600Nm, driving through quattro all-wheel drive, the quattro sport differential and an eight-speed tiptronic gearbox, good for 0-62mph in around 4.1 seconds. The Carbon Black styling pack, gloss black Audi rings and badging, 20 inch gloss black Audi Sport alloys and red RS brake calipers complete the look. Inside you get RS super sport seats in honeycomb-stitched leather, heated and electrically adjustable in the front with a pneumatic massage function, along with carbon twill inlays, the Audi Virtual Cockpit with RS displays, MMI Navigation Plus, Apple CarPlay through the Audi Smartphone Interface, three-zone climate control, Matrix LED headlights with dynamic indicators, keyless go, privacy glass and a powered tailgate. It has been serviced by Audi main dealer Poole Audi, and we've serviced it again ourselves as part of our preparation, fitting new rear brake pads at the same time.
