Vehicle Background

In the early 1970s, Porsche aimed to bolster its presence in motorsport, particularly in the Group 4 GT racing category. To achieve this, they needed to produce a road-legal version of their race car to meet homologation requirements. Thus, the 911 Carrera 2.7 RS was conceived, blending track-bred performance with road-going usability.

The “2.7” in its name refers to the displacement of its engine, a larger and more powerful version of the flat-six engine than what was previously offered. The “RS” designation stands for Rennsport, which translates to “racing sport” in German, signifying its strong racing pedigree.

Design and Features

The 911 Carrera 2.7 RS retains the classic 911 silhouette but adds several distinctive elements. The aforementioned “ducktail” spoiler not only aids in downforce but also gives the RS its iconic look. The car is available in several striking colours, often with contrasting “Carrera” script decals along the sides.

Inside, the focus is on functionality and weight saving. The seats are lightweight bucket seats, and creature comforts are minimal, reflecting its racing intentions. However, despite its spartan nature, the RS still provides the quintessential 911 driving experience – engaging, responsive, and thrilling.
