If you really want to understand the Audi brand and its latest innovations you have to know the four Audi brand assets – most customers do not. The concept "The Power of Four" showcases these four brand assets and provides visitors with a full immersion experience of the Audi brand. The visit to the fair is a journey through the four brand assets – culminating with the core asset "Vorsprung durch Technik." Before visitors reach the main exhibit, they traverse a path staged with four multi-sensorial experience chambers, called the "Audi Experience Walk." With the impressions of the Audi brand assets still immediate, visitors then enter the main exhibition.
