The Salon is scheduled by the Organisation Internationale des Constructeurs d'Automobiles, which considers it a major international auto show. Almost all motor combustion models have been featured in the show — ranging from benzene to steam, with many exotic and supercars stealing the spotlights throughout the 20th century. Prototypes, new equipment, technical breakthroughs, and international partnerships as well as political and social debates are all landmarks of this international exhibition. The show is regarded as the most level playing field for carmakers with Switzerland lacking an auto industry.
