 In January 1978, Audi presented the newly developed Audi Quattro to the company leadership on the Turracher Höhe, where the performance of the new all-wheel drive could be convincingly demonstrated on the steep, curvy and snowy road of the pass.The pass road has a maximum gradient of "only" 23% today on a short section on the Carinthian side.It is well cleared in the winter and only has to be closed very rarely.
