- André Citroën (1878–1935) built armaments for France during World War I; after the war, however, he realized that unless he planned ahead he would have a modern factory without a product. Citroën was already experienced in the automotive business, thanks to a successful six-year stint working with Mors between 1908 and the outbreak of war.The decision to switch to automobile manufacturing was taken as early as 1916, which is the year when Citroën asked the engineer Louis Dufresne, previously with Panhard, to design a technically sophisticated 18HP automobile he could produce in his factory once peace returned. Long before that happened, however, he had modified his vision and decided, like Henry Ford, that the best post-war opportunities in auto-making would involve a lighter car of good quality, but made in sufficient quantities to be priced enticingly. In February 1917 Citroën contacted another engineer, Jules Salomon, who already had a considerable reputation within the French automotive sector as the creator, in 1909, of a little car called Le Zèbre. André Citroën's mandate was characteristically demanding and characteristically simple: to produce an all-new design for a 10 HP car that would be better equipped, more robust and less costly to produce than any rival product at the time.
- The result was the Type A, announced to the press in March 1919, just four months after the guns fell silent. The first production Type A emerged from the factory, located at Quai de Javel, Vaugirard, Paris, at the end of May 1919 and in June it was exhibited at a show room at Number 42, on the Champs-Élysées in Paris which normally sold Alda cars. Citroën persuaded the owner of the Alda business, Fernand Charron, to lend him the showroom, which is still in use today. This C42 showroom is where the company organizes exhibitions and shows its vehicles and concept cars. A few years later, Charron would be persuaded to become a major investor in the Citroën business. On 7 July 1919, the first customer took delivery of a new Citroën 10HP Type A.
- That same year, André Citroën briefly negotiated with General Motors a proposed sale of the Citroën company. The deal nearly closed, but General Motors ultimately decided that its management and capital would be too overstretched by the takeover. thus Citroën remained independent till 1935.
- Between 1921 and 1937, Citroën produced half-track vehicles for off-road and military uses, using the Kégresse track system. In the 1920s, the U.S. Army purchased several Citroën-Kégresse vehicles for evaluation followed by a licence to produce them. This resulted in the United States Army Ordnance Department building a prototype in 1939. In December 1942, it went into production with the M2 Half Track Car and M3 Half-track versions. The U.S. eventually produced more than 41,000 vehicles in over 70 versions between 1940 and 1944. After their 1940 occupation of France, the Nazis captured many of the Citroën half-track vehicles and armored them for their own use.
- The Eiffel Tower served as a billboard for Citroën from 1925 to 1934.
- Citroën used the Eiffel Tower as the world's largest advertising sign, as recorded in Guinness World Records. He also sponsored expeditions in Asia (Croisière Jaune), North America (Croisière Blanche) and Africa (Croisière Noire), demonstrating the potential for motor vehicles equipped with the Kégresse track system to cross inhospitable regions. These expeditions conveyed scientists and journalists.
- Demonstrating extraordinary toughness, a 1923 Citroën that had already travelled 48,000 km (30,000 mi) was the first car to be driven around Australia. The car, a 1923 Citroën 5CV Type C Torpedo, was driven by Neville Westwood from Perth, Western Australia, on a round trip from August to December 1925. This vehicle is now fully restored and in the collection of the National Museum of Australia.

- In 1924, Citroën began a business relationship with the American engineer Edward G. Budd. From 1899, Budd had worked to develop stainless steel bodies for railroad cars, for the Pullman in particular. Budd went on to manufacture steel bodies for many automakers, Dodge being his first big auto client. At the Paris Motor Show in October 1924, Citroën introduced the Citroën B10, the first all-steel body in Europe. These automobiles were initially successful in the marketplace, but soon competitors who were still using a wooden structure for their vehicles, introduced new body designs. Citroën, who did not redesign the bodies of his cars, still sold in large quantities nonetheless, the cars' low price being the main selling point, which factor however caused Citroën to experience heavy losses.[citation needed]
- In 1927, the bank Lazard helped Citroën by bringing new much-needed funds, as well as by renegotiating its debt—for example, by buying out the Société de Vente des Automobiles Citroën (SOVAC). It went even further by entering in its capital and being represented on the board; the three directors sent by Lazard were Raymond Philippe, Andre Meyer and Paul Frantzen. André Citroën perceived the need to differentiate his product, to avoid the low price competition surrounding his conventional rear drive models in the late 1920s and early 1930s. In 1933 he introduced the Rosalie, the first commercially available passenger car with a diesel engine, developed with Harry Ricardo.

- Traction Avant
- The Traction Avant is a car that pioneered the mass production of three revolutionary features that are still in use today: a unitary body with no separate frame, four wheel independent suspension and front-wheel drive. Whereas for many decades, the vast majority of motor cars were similar in conception to the Ford Model T – a body bolted onto a ladder frame which held all the mechanical elements of the car, a solid rear axle that rigidly connected the rear wheels and rear wheel drive. The Model T school of automobile engineering proved popular because it was considered cheap to build, although it did pose dynamic defects as automobiles were becoming more capable, and resulted in heavier cars, which is why today cars are more like the Traction Avant than the Model T under the skin. In 1934 Citroën commissioned the American Budd Company to create a prototype, which evolved into the 7 fiscal horsepower (CV), 32 hp (24 kW) Traction Avant.
