Audi has also sought to improve on the previous RS6's fuel economy by 40%, outfitting the wagon with stop/start engine management and cylinder deactivation. All that while including 60 cubic feet of cargo space. Try that in a Porsche.
Unfortunately the RS6 Avant will not be made available in the United States, but as we go to press, rumors are circulating that Audi is preparing to introduce a similarly-equipped RS7 Sportback designed with the North American market in mind. In the meantime, it has announced new versions of the SQ5 performance crossover and RS5 Cabriolet specifically for American buyers. Watch this space for more.
