NSU licensed the Wankel engine design to companies worldwide, in various forms, with many companies implementing continual improvements. In his 1973 book ''Rotationskolben-Verbrennungsmotoren'', German engineer Wolf-Dieter Bensinger describes the following licensees, in chronological order, which is confirmed by John B.

In 1961, the [[Soviet Union|Soviet]] research organizations of NATI, NAMI, and VNIImotoprom began developing a Wankel engine. Eventually, in 1974, development was transferred to a special design bureau at the [[AvtoVAZ]] plant.<ref name="cu0Uy">{{cite journal |url= http://engine.aviaport.ru/issues/11&12/page14.html |first1=Ivan |last1=Pyatov |title=RAP from inside and outside (РПД изнутри и снаружи) |journal=Engine (Двигатель) |volume=5–6 (11–12) |date=September–December 2000 |language=ru |access-date=2011-12-11 |archive-url= https://web.archive.org/web/20111002120904/http://engine.aviaport.ru/issues/11%2612/page14.html |archive-date=2011-10-02 |url-status=dead}}</ref> John B.
