2007 Audi RS4
Downsizing engines and expanding green technologies is the new wave in performance engineering as companies strive to meet toughening fuel economy and emissions regulations on both sides of the Atlantic.
And with Audi’s performance portfolio already consisting of the recently revealed RS3, and U.S.-bound RS5 and TT RS, as well as the R8, a new-generation RS6 and possibly even a new mid-engine model dubbed the R4, there’s very little room for another RS model, especially in these times of environmental consciousness.
Additionally, over the course of the coming years, Audi will start to release its first trickle of all-electric e-tron sports cars, so you can hardly say there’ll be a serious lack of sporty models wearing the Four-Ring badge.
