The 2021 RS4 is the very top of the range performance model in the A4 line up, and only comes around every so often, so it's rare that it's available, and that means used car values are incredibly strong, helping justify the initial high purchase cost. The new Audi RS4 utilises an all new 2.9 litre 6 cylinder Turbo petrol engine that's got a huge surge of mid range power. The RS4 is only available so far in Estate format, or Avant in corporate speak. Standard equipment includes 19 inch alloys, Audi virtual cockpit. flat bottomed sports steering wheel, MMI navigation, super sports seats, RS Body styling pack, LED interior light pack and the sound system with 10 speakers. The RS4 carbon edition is also available in a similar manner to how the black edition is available on the normal A4, it doesnt boost performance but enhances the appearance of the car adding larger 20" alloy wheels, red brake calipers, a sports exhaust, matrix LED headlights, privacy glass, carbon engine cover, door mirrors, a carbon matt aluminium styling pack and carbon dashboard inlays.
