Maximag
Maximag was the name of a Swiss automobile, produced by Motosacoche, based at Carouge, a suburb of Geneva, from 1923 till 1928.
By the time it embarked on automobile manufacturing, the company had already established itself as a maker of engines and motor cycles.
From 1924 the cars were also assembled in Lyon which enabled them to be sold in France without being penalized by the tariff barriers that separated the national markets of the two countries in question.
