Although its name is the German Motorcycle Museum, there are historic cars here, too. Displays include the the 1885 Daimler machine that started us on the road to motorized mobility, the world's first mass-produced motorcycles (Hildebrand and Wolfmüller), and exhibits on racing. Also here is the NSU Museum, an early motorbike manufacturer acquired by the precedessor of the company now called Audi, which has an auto production facility in Neckarsulm. The collections are arranged over five floors in a handsome 400-year-old castle that belonged to the Teutonic Knights until 1806. The Audi factory offers tours.
