The Porsche 911 was introduced as the successor to the 356 series in 1963 at the International Motor Show in Frankfurt as the Porsche 901. This name had to be changed for copyright reasons in 911 because Peugeot had already secured all the combinations of numbers with a 0 in the middle of their series. Compared to the Porsche 356 the Porsche 911 was, technically speaking, a quantum leap.
The self-supporting body was significantly higher compared with the 356, and thus provided more room inside. Even taller drivers now easily found their position in the coupe. More visibility is given by the larger windows and a larger luggage compartment now offered space for a golf bag, a requirement supposedly given by Ferdinand Porsche.
The new air-cooled six-cylinder boxer engine in the rear of the new Porsche 911 has a higher smoothness than the four-cylinder boxer engine of the 356 model. The performance of the 2 liter engine was originally 130 hp at 6100 rpm. The fuel mixture is treated in two triple-downdraft carburetor.
A mechanical injection double row pump, is preparing the 2.7 liter engine of the Porsche 911 Carrera RS 2.7 to the mixture. This allows a maximum 210 hp.
This racing car should not be reserved coming as a touring car onto the road. To receive the Sports homologation Porsche had to built at least 500 models with roadworthiness of the special 911 RS models.
1972 Porsche introduced therefore at the Paris Motor Show, the Porsche 911 Carrera RS with the 2.7 litre engine. One in every detail slimmed-down, lightweighted race car. At first Porsche feared that the model would not sell because of that oil crisis. But the opposite happened and Porsche presented again to 500 vehicles.
To reduce weight, thinner metal was used for the body, a thin lightweight glass from Belgium for windscreen, rear and side windows, renouncements were made on insulation materials, no sunshade on the passenger side and on the dashboard clock.
With the 210 hp strong 2.7-liter Carrera 6-cylinder boxer engine, the RS reaches a top speed of 240 km / h. The performance can be seen, but even more clearly in the acceleration. Thus, the RS moves from 0 to 100 in 5.8 seconds. This corresponds to a power factor of 4.6 kg / hp
The circuit is extremely soft and speaks well of the vehicle at any speed. A very stable braking system brings the Porsche RS securely to a halt, even under the greatest exposure.
Only 500 units were built of the 2.7 RS models. For experts it is one of the best sports cars of the 70s and desires in every Porsche collection.
