Renault introduced its twin-cylinder Model AX in 1908 at the London Motor Show. The French magazine Omnia described it as 'It is very much to the taste of the public, who see it as a move towards the voiturette... that car for poor people that can render so many services. I hope that they won't weigh down this nice little chassis, built to carry neat two-seater bodywork, with huge coachwork capable of carrying five people!'
The twin-cylinder Renault AX was soon put into service as a taxicab in Paris and London, and is fondly remembered for rushing reinforcements to the front in September 1914 when the advancing German Army threatened Paris. The services rendered earned it the title 'Taxi de la Marne', and one of these gallant Renault taxis was immortalized with a spot within the Les Invalides in Paris.
The 1,060cc inline 2-cylinder engine powering the Type AX had a single Updraft carburetor and produced 7 horsepower at 1,800 RPM. It had a three-speed manual transmission, two-wheel drum brakes, and a suspension comprised of semi-elliptical springs. The AX could reach a top speed in the range of 35 mph.
The Type AX was renowned for its durability and reliability. Coachwork was usually two- or four-seat configurations.
