BMW commenced production of a new swing front axle on 17th December 1930 and first sales commenced on 10th February 1931. These were built in parallel with the fixed axle variety but more swing axle models were offered than the rigid. viz: chassis, open 2-seater, tourer, saloon, coupé 2 and 4-seater cabriolet.
This new BMW 3/15 PS DA4 had other features - a shorter scuttle, and a more spacious body accomplished by the deletion of the luggage boot.
The swing axle was not without controversy particularly from Dipl.-Ing. Josef Ganz, the publisher of the Motor Kritik magazine. He argued that the camber angle changed when the suspension was compressed and this was dangerous. A fierce argument developed between the two parties. Initially BMW did not accept the criticism but did eventually made changes.
Of interest is that at this time sales were falling. BMW approached Austin requesting the agreed licence fees be reduced. Herbert Austin reacted angrily to this and in a five page letter pointed out all the errors he perceived that Dixi / BMW had made - design, price and too large factory premises. An argument ensued, but Austin stood his ground.
By the end of '31 compete cessation of vehicle production was seriously considered by BMW.
