The company changed its name to Steyr-Werke AG in 1926. In 1934, Steyr merged with Austro-Daimler-Puch to form Steyr-Daimler-Puch. The range produced in these years mainly consisted of very modern designs, sporting partially or complete unit construction bodies in streamlined livery, from the one-litre Steyr 50 to the 2.3 L Steyr 220 "six".
