Experimental rotary-piston engineIt was in April 1954 that Felix Wankel discovered how to achieve a four-stroke engine operating cycle with a triangular piston turning around separate axes in a suitably shaped housing. An experimental rotary-piston engine was built, and ran for the first time on a test rig in the NSU company’s research department in Neckarsulm. Advantages of the rotary-piston engine are that fewer parts are needed and weight is thus saved. | |
NSU Wankel Spider In September 1963, NSU displayed its NSU/Wankel Spider at the German Motor Show in Frankfurt. It was the first series-production car in the world to be driven by a rotary-piston engine.
