German carmaker NSU presents the new NSU Spider, the world's first Wankel engined car, on 29 September 1964. The Spider was unveiled at the “Internationale Automobilausstellung in Frankfurt” in 1963 (12/09/1963 – 22/09/1963). The two-door cabriolet, based on the NSU Sport Prinz, was designed by Bertone.
The engine invented by Felix Wankel, differed from a classic piston engine due to the quasi-oval design of the combustion chamber, containing a rotor that ascribed within the chamber an epitrochoid shaped trajectory, enabling the combustion pressure to be converted directly into a rotary motion. The rear-mounted 498 cc engine had a power output of 40 kW with a top speed of 150 km/h.

Between 1964 and 1967 2,375 NSU Spiders were built. In 1967, the model was withdrawn with the introduction of NSU's second rotary-engined car, the Ro 80.
