The Adler Trumpf Junior is a small car that was introduced by the automobile company Adler in 1934. The car featured front-wheel drive like its larger sibling, the Trumpf, but had an engine with just under 1 liter of displacement. The modern design was created by Hans Gustav Röhr. This model 1G was sold 24,013 times until 1935. From the improved successor model 1E, 78,827 vehicles were produced between 1936 and 1941. After the war, this car was intended to help the Adler company restart in passenger car manufacturing in an even more improved form. After two prototypes with bodies from Wendler and Karmann were created in 1948, the management decided to focus solely on manufacturing motorcycles in the future. The prototypes were scrapped.
