The Porsche 911 (pronounced Nine Eleven or German: Neunelfer) is a two-door, 2+2 high performance classic German sports car made since 1963 by Porsche AG of Stuttgart, Germany. It has a rear-mounted six cylinder boxer engine and all round independent suspension.
The 911 has been modified by private teams and by the factory itself for racing, rallying, and other forms of automotive competition. It is among the most successful competition cars. In the mid-1970s.
The 911 traces its roots to sketches drawn by Ferdinand "Butzi" Porsche in 1959. The Porsche 911 was developed as a more powerful, larger, more comfortable replacement for the Porsche 356, the company's first model.
For the 1978 model year, Porsche revised the 930 with a larger 3.3-litre turbocharged engine with intercooler that produced 300 PS (220 kW; 300 hp). To fit the intercooler a newly designed "tea-tray" tail replaced the earlier whale tail.
