The story
Production of cars and light trucks began at the company's Paris workshops in the rue de Berri, in 1919. The name Ateliers d'Automobiles et d'Aviation was generally reduced to AAA'.
With the First World War having ended only months earlier, there was at the time little contact between auto producers in France and those in Germany. There is no connection between Paris-based Ateliers d'Automobiles et d'Aviation (AAA) and the Berlin company AG für Akkumulatoren- und Automobilbau which between 1919 and 1922 was also producing cars under the name "AAA".
