In 1972, the FIA effectively pushed Porsche’s fearsome, Le Mans-winning 917 prototypes off the stage by limiting engine displacement to three liters. The company had to fall back on its bread-and-butter production cars to compete in the World Championship for Makes.
The 2.4-liter 911 S was not deemed strong enough for competition, so Porsche decided to upgrade to a 2.7-liter engine, larger wheels and body modifications to match– including flared rear quarter-panels and an intriguing rear spoiler that became known as the infamous “ducktail.”
The new model, branded the Carrera RS, was duly homologated with the construction of 500 examples to meet the new class rules. These would serve as the basis for even more potent versions as the ferocious Group 5 2.8 and 3.0 RSRs would come to dominate GT racing, especially in the U.S.
In total, 1,590 examples were built (including “Homologation,” or “H” cars), thus enough to qualify the model for Group 3, standard GT production cars.
