110 years of Felix Wankel - rotating to the end and not a bit fickle
Summary
Felix Wankel can be counted among the great inventors in automotive engineering because he made the completely new and independent principle of the rotary piston engine acceptable. However, the Wankel engine never became as widespread as the petrol and diesel piston engines. In the year of Felix Wankel's 110th birthday, his engine practically disappeared from the scene with the discontinuation of the Mazda RX 8, even though the ideas were captivating in and of themselves. This report looks back on the history of the Wankel engine, names and lists the most important vehicle models with Wankel engines and shows them in an extensive picture gallery. The references to other previously published reports on Wankel vehicles are also recommended.

Felix Wankel can be counted among the great inventors in automotive engineering because he made the completely new and independent principle of the rotary piston engine acceptable. However, the Wankel engine never became as widespread as the "Schüttelhuber" (quote from Wankel) of Nicolaus Otto and Rudolf Diesel. In the year of Felix Wankel's 110th birthday, his engine practically disappeared from the scene with the discontinuation of the Mazda RX 8. Nevertheless, the idea is still captivating today. Anything but a "Schüttelhuber" When the car learned to drive, the loud engines of these early vehicles shook and rattled like a wet dog. The first balancer shafts appeared, and advertising (back then still called advertising) was very quick to come up with snappy slogans about "noiseless and low-vibration running". But the young Felix Wankel, who was born right in the early years of motoring, was not impressed. The concept of a truly vibration-free engine therefore became a fixed idea. There were hundreds of alternative concepts to the reciprocating piston principle, and the rotating disk had also been known as an idea for some time and was not Wankel's invention. However, it was not until 1944 that Wankel was able to realize a reliable test engine at his institute in Lindau on Lake Constance, and it would take until the 1960s before it went into series production. The NSU Wankel Spider appeared in 1964 as the world's first series-produced Wankel car. The road to this was long and full of obstacles.
