As a copywriter, I've researched the automotive industries in Germany and found out that they are mainly located in several key regions. The most prominent areas include the state of Baden-Württemberg, where big brands like Mercedes-Benz and Porsche have their headquarters. Besides that, Bavaria is home to BMW and Audi, while Volkswagen can be found in Lower Saxony. Overall, these regions form the backbone of Germany's strong automotive industry, which is known for its innovation and high-quality products.
