It originally was designated as the "Porsche 901" (901 being its internal project number). The car was developed with the proof-of-concept twin-fan Type 745 flat-six engine, but the car presented at the auto show had a non-operational mockup of the single-fan 901 engine, receiving a working unit in February 1964. The new car made its public debut at the 1963 Frankfurt Motor Show ( German: Internationale Automobil-Ausstellung).

The Porsche 911 was developed as a more powerful, larger and a more comfortable replacement for the 356, the company's first model. The 911 traces its roots to sketches drawn by Ferdinand "Butzi" Porsche in 1959. The original Porsche 901 on display at the 2019 Geneva Motor Show Now available as an RS (Renn Sport) model only. No cabriolet version has ever been produced to date.
