In celebration of the 30th anniversary of the debut of the quattro, Audi presented a show car at the 2010 Paris Motor Show that sets the stage for Audi's future: the Audi Quattro Concept.
But since 2010 the rumors have all but stopped. That is until recently when they were rekindled by word is that Audi is taking the Quattro Concept upmarket in a big way, with a tuned version of the twin-turbo 4.0-liter V8 from the RS7 churning up in the neighborhood of 650 horsepower.
Others believe that the new Audi Quattro will be based off an S5, with insiders claiming a 408-hp Quattro will be ready for a launch in 2013.
