Ata was a Belgian automobile marque produced by the Ateliers de Construction d'Automobile Texeira, based in Trooz, Belgium. The company's activity was brief, as its development was interrupted by the outbreak of World War I.
During its short existence, the firm offered four models, each powered by a four-cylinder engine: the 1469cc 10CV, the 2154cc 12CV, the 3014cc 16CV, and the 4070cc 20CV. This range suggested an ambition to cover a broad segment of the market, from smaller touring cars to larger, more powerful vehicles.
The factory was managed by Mathieu van Roggen, who later went on to lead Imperia starting in 1919. It was into Imperia that the Texeira business was eventually absorbed, marking the end of the Ata marque as an independent entity.
Although its production life was cut short, Ata remained a notable example of early Belgian automotive manufacturing, reflecting the broader industrial ambitions of the pre-war period before consolidation reshaped the country's car industry.
