The Porsche 911 (pronounced as nine eleven) is a sports car made by Porsche AG of Stuttgart, Germany.
The famous, distinctive and durable car has undergone continuous development since its introduction in 1964. Mechanically it is notable for being rear engined and, until the introduction of the all-new Type 996 in 1999, air-cooled.
Since its inception the 911 has been modified, both by private teams and the factory itself, for racing, rallying and other types of automotive competition. It is often cited as the most successful competition car ever, especially when its variations are included, mainly the powerful 935.
In the international poll for the award of the world's most influential car of the twentieth century the 911 came fifth after the Ford Model T, the Mini, the Citroën DS and the Volkswagen Beetle.
It is the most successful surviving application of the air (or water)
cooled opposed rear engine layout pioneered by its original ancestor, the Volkswagen Beetle.
The Porsche 911 was developed as a much more powerful, larger, more comfortable replacement for the Porsche 356,
the company's first model, and essentially a sporting evolution of the Volkswagen Beetle.
The new car made its public debut at the
1963 Internationale Automobil-Ausstellung, better known to English speakers as the Frankfurt motor show.
