Adler – The German Eagle of Technical Progress
Adler was one of the pioneers of the German automotive industry. It began producing cars at the turn of the 20th century and quickly established itself thanks to high-quality engineering and advanced technologies. In the 1930s, it became one of the leaders in implementing front-wheel drive and aerodynamic bodywork. Adler cars were also successful in international racing. The company ceased car production during World War II.
