1974 Porsche 911 2.7 Carrera Turbo – Ultimate Guide
Chassis 5600042 is a very special car that was presented to Louise Piech on August 28th 1974 for her 70th birthday and now lives in the factory museum. This is the first road-going 911 Turbo and was a testbed car. This 2.7 Carrera Turbo pre-dated the prototype 930 that was shown in almost production-ready guise at the Frankfurt Motor Show in October 1974 so it is worth a page of its own.
It was based on a standard early 1975 model year Carrera 2.7 and got an engine with a single turbocharger and Bosch K-Jetronic injection system. The compression ratio, power output and torque rating were never published.
From the outside, nothing suggested the 2.7 Turbo was anything out of the ordinary. It used a standard narrow body pre-930 shell which was still badged as a Carrera.
After chassis 5600042 had completed its development programme, Porsche carried out a number of modifications ahead of the car’s handover to Louise Piech. The changes included new red leather upholstery with red and blue MacLaughlan tartan seat centres and matching door cards. Fresh red carpet and a black headliner were installed along with a Blaupunkt four-speaker stereo plus electric antenna and a voice recorder. Outside, tartan side decals matched the seat centres.
