The exterior of this RS6-R shows a front splitter, side skirts, rear spoiler and rear diffuser made from carbon fiber. While inside the cabin, there are a lot of carbon fiber treatment as the standard RS6 but it now has an RS6-R plate on its dashboard. The blue color RS6-R badge also can be found on its seats which receive a new wrapped with Alcantara and leather.
