Inspired by the new autobahns, in the 1930s Mercedes-Benz offered several car models, including the 320, as so-called streamlined sedans. Even though the improvements in consumption and top speed were minimal, the streamlined Mercedes-Benz sedans were the most stylish means of travelling on the autobahn in all comfort and safety.
