In 1926, Protos (which had built the winner of the New York-Paris race) was acquired from Siemens-Schuckert, leading to "a series of dull six-cylinder cars". The next year, NAG again expanded by taking over Presto, which had just bought Dux, and continuing to build the 2.6-liter Typ F and 3-liter Typ G. The difficulty was that despite their quality, none of them was distinctly different from other German cars of the period.
