The Carrera RS debuted in October 1972 at the Paris Motor Show, and is considered to be Porsche’s de facto first-gen 911 halo car. It’s surely one of the best road cars of all time. Fitted with flared wheel arches, a distinctive ducktail spoiler, and a highly tuned flat-6 engine, the brilliant Carrera 2.7 RS is the model against which all subsequent high-performance 911s are judged.
