The Adler Favorit was made as cheaper alternative to the Adler Standard 6 beginning in 1929. It was propelled by a 35 HP four-cylinder engine. Outwardly, the both types are very similar but the Favorit had always only five wheel bolts.
The vehicle on both photos is the same Adler Favorit of the years of construction 1930/31. As a distinguishing mark, the number of cylinders is displayed in form of a 6 on the headlights supporter in the case of the Adler Standard 6.
The Adler Favorit 4 K ambulance was based on the chassis of the Adler Favorit passenger car. It was manufactured from 1929 to 1934. There was a similar vehicle based on the Standard 6.
