To commemorate the 30th anniversary of the original Quattro, Audi is planning (supposedly) to unveil a production version of the 2010 Quattro Concept. A tribute to the original and legendary 1984 Sport Quattro, the automaker is planning to debut a production version at Frankfurt this September. The new Quattro has a “sharper” shape and incorporates a number of lightweight components such as carbon fiber, aluminum and magnesium. Rumors suggests power will come from a twin-turbo 4.0-liter V8 that’s good for around 650 hp.
