6/30 hp automobile, 1928
Its engine was tested under race conditions in the 6/60 hp compressor racing car. The vehicle proved its absolute reliability in an 18-day day-and-night test on the Nürburgring (North Circuit), where it covered 20,000 kilometres without a breakdown. The 6/30 hp was built on the production line of the newly built branch plant in Heilbronn. The vehicle was available as a 4-seater Phaeton, as a 6-window, 4-seater saloon and as a sports roadster with two foldaway seats.
