I don't know, of course, but the Typ12 was created (just) before the Tatra V570 (second prototype, the first looked very different): https://en.wikipedia.org/wiki/Porsche_Type_12 https://en.wikipedia.org/wiki/Porsche_Type_12 https://en.wikipedia.org/wiki/Tatra_V570 https://en.wikipedia.org/wiki/Tatra_V570 and it seems like both Porsche and Ledwinka worked at Steyr so it is very possible that some earlier Ledwinka project at Steyr "inspired" Porsche, and possibly also viceversa, in any case they had very similar education and experience in overlapping years.
