Few Porsche models are as iconic as the 911 Carrera RS 2.7 and a particularly stunning example is currently up for sale in Culver City, California.

The car came to life after Porsche decided to enter the FIA Group 4 GT/Special Sports Car category with a race car based around the 911 S. To meet homologation requirements, it needed to build 500 road-going examples and ultimately launched the Carrera RS 2.7.

The car was initially presented at the 1972 Paris Auto Show in Touring and Sport guises and quickly sold out. This prompted Porsche to build more examples and by the time production had ended, 1,525 units were sold. Of these, 200 were M471 Lightweight models, 1,308 were M472 Touring variants, and 17 of these were RSH models like this one, also known as the homologation model.

The RM Sotheby’s listing reveals that this Carrera RS 2.7 RSH rolled out of Porsche’s factory in May 1973 and is finished in Light Ivory. It traded hands on a number of occasions over the years and while under the ownership of Oregon Porsche collector Mark Heininge, underwent a full restoration in the mid-1980s.

Heininge revealed that a previous owner had installed wider fender flares but they were not original parts. The front fenders were later modified and OEM rear-quarter flares were installed to return the car to its original design.

The car has undergone more work over the last couple of decades and in 2016, the chain tensioners, exhaust system, and various chassis and engine hardware components were returned to the original specification.

Powering the car is a 2.7-liter naturally aspirated flat-six that produces 210 hp at 6,300 rpm and 188 lb-ft (255 Nm) of torque at 1,500 rpm. While RM’s listing doesn’t provide mileage details, it does confirm an asking price of $1.35 million.
