Wolfsburg is famous as the location of Volkswagen AG's headquarters and the world's biggest car plant. The Autostadt is a visitor attraction next to the Volkswagen factory that features the company's model range: Audi, Bentley, Bugatti, Ducati, Lamborghini, MAN, Neoplan, Porsche, Scania, SEAT, Škoda Auto and Volkswagen Commercial Vehicles. Wolfsburg is one of the few German cities built during the first half of the 20th century as a planned city. From its founding on 1 July 1938 as a home for workers producing the "KdF-Wagen" (VW Beetle) until 25 May 1945, the city was called "Stadt des KdF-Wagens bei Fallersleben". In 1972, the population first exceeded 100,000.
