In March 1981, Pininfarina presented the Audi Quartz at the Geneva Motor Show, a reinterpretation of the Audi Quattro, which had been shown for the first time a year earlier. Created with the help of Automobil Revue to mark its 75th birthday, the elegant coupé thrilled visitors to the show at the time. The prototype was an exception in many respects, not least because it was drivable and even underwent a test drive. This report tells the story of the Audi Quartz and shows it together with its production counterpart, the Audi Quattro, in many pictures.
