This year Audi once again has many historically significant events to celebrate, with one especially important anniversary: 30 years of quattro. At the world’s largest classic car show, the Techno Classica in Essen, Germany (April 7 – 11), Audi Tradition will therefore be exhibiting four Audi quattro models of outstanding interest. And at the museum mobile in the Audi Forum Ingolstadt, there will be a special exhibition from April 28 to July 31 devoted to “30 Years of quattro”. This year Audi Tradition is taking its motor-vehicle treasures to an unusually large number of events.
