The DKW Sonderklasse 1001 was produced from October 1932 until 1934 in three versions: 2-door Cabrio-Limousine (puzzle car), 4-door Limousine and Phaeton. The Sonderklasse 1001 was technically nearly identical to Sonderklasse Typ 432. The 1001 used also the frameless plywood-body construction, but with a 9 centimeter longer wheelbase than the Typ 432, which benefited the front bonnet.
