Opis modelu: Types 300 / 320 / 350 (W 03, W 04, W 05)
Apart from the 8/38 hp the 12/55 hp (type 300), too, was presented on the Berlin Automobile Exhibition in 1926. This design, drawn by Ferdinand Porsche, had become a bit too massive and did not catch on with the customers although its engine had soon been enlarged to 3.2 litres and finally to 3.5 litres displacement.
