Zwickau, the fourth largest city in Saxony with a population of just under 88,000, is home to the museum in the oldest part of the former Audi plant. After extensive renovations, the museum was reopened in 2004 and expanded in 2017. Around 160 large automotive exhibits and numerous smaller exhibits are displayed on 6,500 m² of exhibition space. The museum is also an anchor point on the European Route of Industrial Heritage. August Horch founded August Horch & Cie. Motorenwagenwerke AG in Zwickau on 10 May 1904. Following a dispute with the Supervisory Board, Horch founded August Horch Automobilwerke GmbH in 1909, which was renamed Audi Automobilwerke GmbH Zwickau after a legal dispute. Audi is the Latin translation of "Horch". Auto Union AG was founded in 1932, uniting the Audi, DKW, Horch and Wanderer brands. The company logo, the four intertwined rings, symbolises these brands. After the Second World War, Auto Union was expropriated and deleted from the commercial register in 1948. The new Auto Union GmbH was founded in West Germany in 1949. VEB Sachsenring Automobilwerke Zwickau, which produced the Trabant, was founded in Zwickau in 1958. The museum offers an impressive permanent exhibition that shows the development of technology and design in automotive engineering. The exhibits range from the beginnings of the Horch and Audi brands to Auto Union, the Trabant and Volkswagen. A special feature of the museum is the scenic embedding of the exhibits in the respective era. The special exhibition "Audi at Le Mans - 24 hours at the limit" shows Audi's successes in the legendary 24-hour race until November 2025. With ten racing cars, including six original winning cars, and other technical treats, an important piece of motorsport history is told.
