SA des Anciens Établissements Secqueville-Hoyau was a French car manufacturer active between 1919 and 1924. The firm was located in Gennevilliers, close to Paris.
The business
Established in 1911 by Alfred Secqueville alongside Gaston Hoyau, the enterprise originally specialized in producing aircraft engines and propellers. Throughout World War I, it produced Bugatti-designed aero engines under license, indicating a potential connection to Bugatti’s engineering team based in Molsheim.
Following the war, the company redirected its efforts solely toward automobile manufacturing from 1919 onward. Vehicles marketed under the Secqueville-Hoyau name reflected the meticulous engineering associated with aircraft engines, featuring adaptable power units, four-speed gearboxes, and ventilated drum brakes.
Manufacturing ended in 1923, with roughly 500 units completed before the final sale occurred in 1924.
The cars
During the 15th Paris Motor Show held in October 1924, Secqueville-Hoyau presented their 10HP model at Stand No. 58. This vehicle was equipped with a 1,243cc four-cylinder side-valve engine and included an electric starter—a significant advancement for that period. Buyers could select from three different wheelbase lengths ranging from to .
At the 1919 motor show, prices for chassis-only models varied between 11,800 and 12,500 francs depending on wheelbase length. Available body types consisted of three- or four-seat “Torpedo” open cars as well as closed “conduite intérieure” sedans, with the long-wheelbase sedan commanding a maximum price of 21,400 francs.
