The Silvretta Classic rally in Montafon is a genuine 500-kilometre challenge for the ambitious historic car owner. It takes place from June 29 to July 2, 2006 and passes through the mountain world of Montafon and the Forest of Bregenz to the Arlberg region. The first day includes the Silvretta Alpine Pass with its 32 hairpin bends, which climbs to 2,032 metres above sea level at the Bielerhöhe summit. Other mountain passes with uphill and downhill gradients as steep as 13 % complete this challenging programme.
Audi Tradition has entered two of its more recent classic sports cars, a green Audi Sport quattro and a red Audi 100 Coupé S.
