Porsche wanted to go racing and needed to meet minimum production of 500 units in order to compete, which is why us lucky Porsche fans now get to dream about owning an RS model. 1580 Carrera 2.7 RS units were made and compared to the 911 S, the Carrera 2.7 RS had a larger engine, more than 210 hp, an upgraded suspension system, better brakes, wider rear wheels and the iconic “ducktail” rear spoiler. The RS Touring version weighed 2370 lb and the Sport Lightweight was 2150 lb. In addition, Porsche made 49 Carrera RSR cars for racing. In 1974, Porsche created an even lighter and faster racing model, the Carrera RS 3.0. With fuel injection and 226hp it was largely based on the 1973 Carrera RSR and cost double the 2.7. The Carrera RSR 3.0 and Carrera RSR Turbo were made in tiny numbers for racing and had tremendous racing success by winning Le Mans in 1974.
