Monotrace

The most common French version of the Mauser Einspurauto was called Monotrace (this means “single track”). Structurally, it did not differ much from the German prototype, but it was equipped with a 510cc engine with 4CV (6 hp) tax power, a folding awning and a front headlight. It also had a three-speed gearbox, a chain-driven rear wheel and manual road wheel control. The weight of the car increased to 320 kg.

Unlike the Mausers, single-seat Monotraces were widely used in motorcycle racing and long-distance races, reaching speeds of up to 85 km/h and consuming only four liters of gasoline per 100 kilometers. The Monotrace range also included a do-it-yourself chassis and a light van. A total of 310 monocars of this make were assembled.

There were also Morgan-Monotrace monocars which were assembled by Monotrace at its factory in Courbevoie near Paris and sold by its trading company from the Champs Elysees. Their only feature was a special spring control system for the side support wheels, patented in 1922 by the German designer Alfred Morgan. Approximately 150 of these machines were built between 1923 and 1926.
