The Schaudel of 1898, which became the Motobloc car or Schaudel Motobloc car, featured unit construction of engine and gearbox, the earliest known instance of this form of design and the reason for the name Motobloc. Furthermore, the change-speed gears were actually in the crankcase. The power unit of the Schaudel Motobloc car was a transversely-mounted, inclined twin with chain drive. This odd little voiturette survived until 1904, after which it was perpetuated only as a van chassis, and a conventional vertical 4-cylinder engine – still made in unit with the gearbox – was substituted. This was a highly efficient unit that soon acquired overhead inlet valves, and it was also very smooth, thanks to the positioning of the flywheel between the two parts of cylinders. A mid-mounted flywheel was also used in the 6-cylinder engine of 1909 and on all Motobloc car models throughout the 1920s. Only fours were made up to 1927, ranging from 1.327cc to 3-litres in capacity. Independent front suspension was introduced on the Motobloc car in 1928, and the 1929/ 1930 range consisted of a Motobloc 9CV, 1.453cc four, and two sixes, a 10CV (1.683cc) and a 15CV (3.013cc).
