Manufactured by Porsche AG of Stuttgart, Germany, the Porsche 911 is a successful sports car. The Porsche 911 was introduced at the 1963 Frankfurt Motor Show. The Porsche 911 is based on the Porsche-designed, Volkswagen Beetle and is famous for the distinctive and durable design. The first sketch for the 911 was made by Ferdinand "Butzi in 1959. The Porsche has been continuously modified by the factory and privately for racing, rallying and other competitions. The Porsche 911 is one of the most successful competition or racing cars. The normally aspirated 911 Carrera RSR in the mid 1970s has won major world championship sports car races such as Targa Florio, Daytona, Sebring or N.
The Porsche 911 classic was a more powerful, larger, more comfortable replacement for the Porsche 356. The first name was 901 as a result of the protest for the name in France, Porsche changed the name to 911 although, internally, the car's part numbers carried on the prefix 901. The earliest edition of the 911 had a 130 PS (96 kW; 128 hp) flat-6 engine, in the "boxer" configuration like the 356, air-cooled and rear-mounted, displaced 1991 cc compared with the 356's four-cylinder, 1600 cc unit. The car had four seats although the rear seats were very small, thus the car is usually called a 2+2 rather than a four-seated. The Porsche 911S model used a discreet spoiler under the front bumper to improve high-speed stability
