Brule-Ponsard (France) - AllCarIndex

Brule-Ponsard was a French automotive manufacturer active during the early 20th century, specifically from 1900 to 1901. The company, officially known as H. Brule et Cie, was based in Paris. It specialized in the production of innovative two-wheeled avant-train units, which provided a self-contained method for motorizing horse-drawn vehicles.

The avant-train units produced by Brule-Ponsard were notable for their use of a 4.5 horsepower Rozcrct Mazuricr three-cylinder engine. This unique engine design utilized a system where the exhaust gases from two cylinders were employed to actuate the third cylinder at a lower pressure, showcasing an early example of engineering ingenuity in automotive design. This engine configuration was also implemented in the company's COMPOUND car, further illustrating their commitment to innovation during their brief period of operation.

Despite its short existence, Brule-Ponsard contributed to the evolution of motorized transport in France, reflecting the technological advancements of the era.
