The 1974 Porsche 911 Carrera RS 3.0 is perceived as the ultimate variant of the naturally aspirated Porsche 911 crafted for racing purposes. It integrates insights gained from prior 911 models and showcases components influenced by the victorious Porsche 917.
When tailored for everyday use, the 3.0-liter six-cylinder engine in the Carrera RS was marginally subdued compared to the 1973 RSR engine, now featuring an aluminum crankcase instead of magnesium. Boasting 230 horsepower at 6200 rpm, it marked the initial 911 model to embrace a 9.8:1 compression ratio, demanding premium fuel. The power was transmitted to the rear wheels through a manual five-speed transaxle furnished with a limited slip differential.
Despite having broader running gear and a less streamlined body, the RS 3.0 managed to achieve a slightly higher maximum speed than its forerunner, the RS 2.7. The elevated power from the 3.0-liter engine rendered the 1974 RS remarkably swift, accomplishing 0 to 62 mph in merely 5.2 seconds.
Porsche manufactured only fifty-five units of the 911 Carrera RS 3.0. The majority of them were utilized by their original owners in Group 3 contests, while just a small number found their way to enthusiasts who regarded them as some of the most exhilarating and lively road cars ever crafted.
