History of the Steyr 12 S 21

The Steyr 12 S 21 was manufactured by the Austrian company Steyr in the early 1930s, during a period when the marque was experimenting with progressive engineering concepts. Steyr, already known for high-quality vehicles since the end of World War I, built the 12 S 21 to meet the growing demand for reliable, mid-sized passenger cars. Positioned between more economical models and larger luxury cars, the 12 S 21 illustrated Steyr’s commitment to innovation with its modern chassis and efficient drivetrain setup for the era.
