ESA (Austria) - AllCarIndex

E.SA was an Austrian automobile manufacturer founded by Egon Seilnacht in Atzgersdorf, Vienna, during the early 1920s. The company operated from 1920 until 1926, during which it produced a limited number of vehicles characterized by their conventional chassis design.

The E.SA lineup included two models, distinguished by their engine configurations: a four-cylinder and a six-cylinder variant. Both models utilized side-valve engines, which were common in the automotive industry at the time. The design of the vehicles initially featured sharply pointed vee radiators, a style typical of many Austrian and German cars of that era, before transitioning to a flat radiator design around 1922.

Production numbers for E.SA were modest, with approximately 200 units of the four-cylinder model manufactured, alongside 30 to 40 units of the six-cylinder model. Despite the small scale of production, E.SA contributed to the automotive landscape of early 20th-century Austria before ceasing operations in 1926.
