Classic BMW Dixi DA 1927


In 1927, 100 Austins were delivered from England and 42 Dixi DA/1's were built in Germany.
In 1928 and 1929, 9,308 Dixi DA/1 models were produced in Germany.
From 1929 until 1931, 12,468 Dixi DA/2 and DA/3 models were made.
In 1931 and 1932, DA/4 models were produced, all under the BMW name.

The DA/4 had independent front suspension, an 18 hp engine and a top speed of 53 mph.
Three leaves were added to the radiator cover to help distinguish the BMW from the Austin.

Classic BMW Vintage 1930


The tapered rear portion drew high praise, being reminiscent of the sports cars and racing vehicles of the time.

From a technical point of view, this model differed little from the normal BMW 3/15 models. An altered cylinder head allowed a higher compression ratio of 7:1 instead of 5.6:1. The intake manifold was made of copper pipe and the exhaust was diverted through two pipes.

These measures produced an increased power output of 3 horsepower at an additional 500 crankshaft revolutions per minute.

Although only 150 copies of this model were produced, the Wartburg Roadster contributed greatly to the popularity of the young automobile maker, BMW.

The little roadster rapidly gained a foothold in sporting events and produced a triple BMW victory in the 750 cc class in July 1930 at the Eifel races at the Nurburgring. The well-known German racer, Bobby Kohlrausch, took 2nd place.
