The International Mobility Show Germany or simply International Mobility Show, in German known as the Internationale Automobil-Ausstellung (IAA – International Automobile Exhibition), is the world’s largest motor show. It is held annually, with passenger vehicles (including some motorcycles) being displayed in odd-numbered years in Frankfurt am Main, and commercial vehicles in even-numbered years in Hannover, Germany. Before 1991, the show was held solely in Frankfurt.
The IAA is organized by the Verband der Automobilindustrie (VDA – Association of the German Automotive Industry) and is scheduled by the Organisation Internationale des Constructeurs d’Automobiles.
