Citroën Type A
Development and introduction
Prior to the First World War, most European automobile manufacturers operated on relatively small production scales. Few factories had annual capacities exceeding 5,000 cars, and moving assembly-line methods were not yet widely adopted in Europe.[1]
André Citroën sought to alter this landscape fundamentally. Having previously established financial success through the manufacture of herringbone bevel gears, he applied industrial-scale thinking to automobile production. The result was the Citroën Type A, introduced in the summer of 1919.[1]
The technical design of the Type A was developed by Jules Salomon, known for his earlier work on the small single-cylinder Le Zèbre. Unlike Salomon’s earlier designs, the Type A was conceived as a practical four-seat motor car built on a 111½-inch (2,835 mm) wheelbase.[1]
The car was powered by a 1.3-litre side-valve four-cylinder engine with a detachable cylinder head. It featured a three-speed gearbox with a centrally positioned gear lever, suitable for either left- or right-hand drive configurations. Final drive was by spiral bevel rear axle.[1]
In keeping with Citroën’s cost-conscious but practical philosophy, certain economies were employed, including quarter-elliptic springs and gravity-fed fuel supply. The foot brake operated on the transmission. The relatively low engine speed (approximately 2,100 rpm) eliminated the need for a cooling fan.[1]
Despite its moderate price — initially £500 in Britain — the Type A was well equipped for the period, including electric lighting and a spare wheel as standard. By 1920, exports to Britain were reportedly reaching approximately thirty cars per day.[1]
Fuel consumption was notably economical for its class, with reported figures of approximately 38 miles per gallon (7.5 L/100 km) on open roads and 30 miles per gallon (9.5 L/100 km) in urban driving. However, the splash lubrication system required relatively frequent oil replenishment, estimated at one pint every 130 miles (approximately 1 litre per 470 km).[1]
By the end of 1921, more than 28,000 examples of the Type A had been produced, marking a significant milestone in the industrialisation of European automobile manufacturing.[1]
