While the TT RS and R8 models are being discontinued, Audi is giving a final nod to gasoline-powered engines with a series of “old-school” RS models. Spy shots have already unveiled a hotter RS6 Avant in development, and it will be accompanied by a next-generation RS4 Avant transitioning to the RS5 Avant nomenclature. Expect another RS5 Sportback and a larger RS7 Sportback to join the lineup.
