Raymond Siran, Cyclecars D'Yrsan was a French enterprise dedicated to manufacturing vehicles in the cyclecar category.
The business
Raymond Siran de Cavanac, who had previous experience with the Levallois-Perret-based automaker S. Sandford, established D’Yrsan in 1923 in Asnières-sur-Seine. The firm specialized in producing compact cyclecar-type automobiles, available with either three or four wheels, with the three-wheeled versions featuring a single rear wheel.
The company halted production in 1930.
Three wheels
The earliest three-wheel models from D’Yrsan bore a strong resemblance to the Morgan vehicles of the same era. The "Model A" was equipped with a 904cc Ruby 4-cylinder side-valve engine rated at 6 HP.
At the 19th Paris Motor Show held in October 1924, the "Model BS" was unveiled, featuring an enhanced 972cc overhead valve engine. Both models shared the same wheelbase and were offered with "Torpedo" style bodies, priced at 9,650 and 10,500 francs respectively.
Subsequently, the "Model DS" incorporated a 1097cc Ruby engine capable of delivering up to . Overall, about 530 three-wheeled units were manufactured, with the majority being "Model BS".
Four wheels
In 1927, D'Yrsan introduced a four-wheeled variant named the "Grand Sport," which utilized the identical 1097cc Ruby powerplant. Production of these four-wheelers totaled around 50 units.
Competition
To enhance its market presence amid limited sales figures, D’Yrsan entered a vehicle in the June 1929 edition of the 24 Hours of Le Mans race. Unfortunately, the car retired after completing only nine laps, covering less than 150 kilometers (93 miles).
