The Mors automobile factory was an early French car manufacturer. It was one of the first to take part in automobile racing, beginning in 1897, due to the belief of the company founder, Émile Mors, in racing's technical and promotional benefits. By the turn of the century, automobile racing had become largely a contest between Mors and Panhard et Levassor. Mors was one of the first automobiles to use the V engine configuration. The Mors 60 horsepower Grand Prix car was powered by a 10 litre V4 side valve engine, with magneto ignition and dry sump lubrication, which could reach 950 rpm. The car had a steel chassis and a four-speed transmission that drove the rear wheels via chain drive, and rear-wheel brakes. In 1902, Mors added pneumatic shock absorbers to their cars, which represented a great leap forward given the quality of the roads and racetracks at the time. With this car, Henri Fournier was able to win the highly significant Paris-Berlin race, with the drive chain breaking immediately afterwards. André Citroën became chairman of Mors in 1908 and restored the company's viability. In 1925, Citroën bought Mors outright and closed it down, using its factory for the production of his Citroën automobiles. The company produced a number of models which were sold widely in Europe and in the USA. In 1905 these ranged from 2.3 litres to the 8.1 litre 40/52 HP and by 1914 Minerva-built Knight sleeve valve engines replaced side-valve units in the larger cars. Post-1918 only sleeve valve engines were used. Citroën's chevron gears were used for the bevel drive rear axles from 1914 and a unique feature was the Mors patented clutch, which had a contracting band system which replaced the cone clutch used until 1903.
