Products and brands

Alfred Secqueville and Gaston Hoyau established their business at Gennevilliers in 1911 as a producer of aircraft engines and propellers. The outbreak of the First World War in 1914 drove an accelerated demand for aircraft, and during the war the manufacturer produced Bugatti designed aero-engines under licence, leading to speculation that their subsequent designs may have been influenced by engineers from Bugatti’s Molsheim plant.

With the outbreak of peace the company switched in 1919 to automobile production, quickly abandoning the production of aero-engines in order to concentrate on the new business. The cars were branded as Secqueville-Hoyaus. Although there was only a single model, the tight tolerances and close adherence to prescribed processes that had been needed to produce aircraft engines enabled the company to produce a high quality modern car with a flexible engine, a four speed transmission and ventilated drum brakes.

Production ended in 1923, however, and the last car was sold in 1924. By this time approximately 500 cars had been produced.
