DKW, an acronym for "Dampf-Kraft-Wagen," was founded in Germany in the early 20th century as a manufacturer of steam-powered and later internal combustion-powered motorcycles, distinguishing itself through technical innovation and two-stroke engines. In the 1920s, it established itself as a leading manufacturer of small motorcycles and affordable automobiles, creating popular and reliable models. In 1932, DKW merged with three other German companies—Audi, Horch, and Wanderer—to create Auto Union, recognizable by the famous four intertwined rings symbol, representing the union of the four brands. During the 1930s and 1940s, Auto Union focused on both small, popular cars and sports and racing vehicles, producing famous Grand Prix single-seaters with advanced engines for the time. World War II interrupted civilian production, and many plants were damaged or dismantled. After the war, the property and plants in East Germany were nationalized, while in West Germany DKW gradually resumed production of automobiles and motorcycles, becoming a leading brand for compact, fuel-efficient vehicles. In the 1950s and 1960s, DKW launched iconic models such as the F89 and F102, continuing to develop two-stroke engines and consolidating its presence on the European market. In 1965, Auto Union was acquired by the Volkswagen Group, which began a gradual transformation and modernization of the range. In the 1970s, the DKW brand was gradually replaced by Audi, which inherited its technology, plants, and expertise, creating more sophisticated and modern vehicles, such as the Audi 60 and subsequent four-cylinder, four-stroke models. Today, the symbol of the four rings lives on in the modern Audi, a global brand that represents innovation, design, and performance, while the history of DKW and Auto Union remains a fundamental chapter in the German automotive industry, witnessing over a century of ingenuity and technological progress.
