First held in 1905, the Salon has hosted almost all major internal combustion engined models in the history of the automobile, along with benzene- and steam-powered cars from the beginning of the century. Exotic supercars often steal the spotlight during their debuts at the show. Prototypes, new equipment, technical breakthroughs, international partnerships, as well as political and social debates, have been announced at the exhibition. The show is regarded as a level playing field for the world's automakers, aided by the fact Switzerland lacks an auto industry of its own.
