Ingolstadt is home to the famous Audi factory that sprawls to the north of the city centre. The two-hour 'Production in a Nutshell' tours of the plant take you through the entire Audi production process, from the metal press to the testing station. The company also runs other more specialist tours that look at small parts of the process, but these are vastly more expensive and more suitable for groups.
