A BMW can now also be bought and paid for in installments.


The DA 3 was equipped as a sports-convertible with 13 kW (18 Hp). The DA 4 marked the end of the series based on the Austin technology. Thus, in 1932 the BMW with the markings 'Ausführung München' (Munich Model) appeared. Unfortunately the new construction of the axles, in the front a swing- and the rear a pendulum axle. did not have desired success with the motor press, rather quite the opposite. On the other hand, the engine, now with overhead valves, was praised.

One big hurdle on the way to a new automobile was the still valid licencing contracts with Austin. It is thanks to the chairman of the board, Popp, who moved mountains in personal conversations with Herbert Austin to get him to agree to a change of contract.


One problem however, remained. In the midst of the consequences of the worst financial crisis of the last century, BMW introduced a newly constructed model, whose body was made by Daimler-Benz in Sindelfingen and whose technology was far more expensive than that of the previous model.


By the way, the relationship with Stuttgart was (still) intact. After all, the BMWs were sold through the Mercedes dealers. The price difference was still large enough. However, Mercedes was already working on cheaper models, right down to engines with a 1,3-liter displacement. Now, BMW would soon be bringing out a 1,2-liter-six cylinder. Could all go well? Of course not.

1932: The unemployment figures in Germany climbed over the 6 million mark.

1933: More than 100 million Reichmarks were confiscated from the trade unions.

1934: Daimler-Benz and Auto Union -> 1 million in (racing) subventions.
