Souriau

The Souriau was first created in Loire-et-Cher, France in 1912 though an experimental model had appeared as early as 1907. The vehicle, also known as the Obus, was powered by either a 5hp 625cc single cylinder engine or a much larger 8hp 1,460cc 4-cylinder engine. The engine provided power by belt to the single front wheel that drove and steered the vehicle. Production ceased in 1914.
