The Renault Taxi de la Marne (Marne Taxi) is an automobile manufactured between 1905 and 1910 by Renault and used as a taxicab. The name Taxi de la Marne was not used until the outbreak of World War I, when the fleet of Paris taxis was requisitioned by the French Army to transport troops from Paris to the First Battle of the Marne in early September 1914.
It was the first car produced after Marcel Renault's death in 1903, along with another four models.
A car-rental company in Paris ordered 1,500 cars in 1905 as a result of a new invention that automatically calculated how much the passenger had to pay. It was called a taximeter and had been invented in 1891. Soon the Taxi de la Marne was popular for the rest of the decade in Paris and also in London from 1907.
