Following the famous 1973 F-model 911 Carrera RS 2.7, Porsche built its successor based on the G-model and it was called the 911 Carrera RS 3.0. With its 172 kW engine, it was the most powerful series production street-legal Porsche made so far. With its new 3.0-liter engine, featuring mechanical fuel injection, it was capable of 230 hp. While 1,580 Carrera RS 2.7s were built for 1973, only 56 Carrera RS 3.0s were built for 1974.
