The Porsche 911 is a 2-door sports car with a rear-mounted engine. It was first presented in 1964 in Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged. This is one of the few car models that historically carries the original concept of the car. The engines were air-cooled until the introduction of the Porsche 911 996 series in 1998.
It originally was designated as the “Porsche 901” (901 being its internal project number). A total of 82 cars were built as which were badged as 901s. However, French automobile manufacturer Peugeot protested on the grounds that in France it had exclusive rights to car names formed by three numbers with a zero in the middle. Instead of selling the new model with a different name in France, Porsche changed the name to 911.
