The 911 Carrera RS 2.7, presented at the Mondial de l'Automobile in Paris in October 1972, was named like earlier racing models after the Carrera Panamericana and was planned as a small series of originally 500 vehicles in order to obtain homologation for racing.  The exterior of the car differed from the other 911s by its front and rear fenders, which were characteristic of all later Carrera models.The engine, which is equipped with a mechanical double-row injection pump, has a displacement of 2.7 liters and generates 154 kW at 6300 rpm (210 hp).
For those who could not acquire the "original model" Carrera RS 2.7 in 1972/73, the G-model was offered with the same 210-hp engine as the 911 Carrera until mid-1975. These 911s were also only available in small numbers (Coupé: 1534 Targa: 610). Today they are similar to the Carrera RS 2.7 sought-after collectibles.
