The icon of 1973

The origin of the myth

The Porsche 911 Carrera RS 2.7 counts as one of the most important icons in motoring history and, for many enthusiasts, is the very embodiment of sporting driving. Shown at the Paris motor show in 1972, it was conceived as a homologation model for motorsport, and combines everyday usability with uncompromising sporting ability in a unique way.

With its distinctive ducktail rear spoiler, its light body and its powerful 2.7-litre engine, the Carrera RS set the standard and laid the foundation for every RS model that followed. The letters RS stand for Rennsport, motorsport.

Originally planned as a limited run of 500 cars, high demand meant that a total of 1,580 cars were built. Those small numbers make it an extremely valuable rarity today.

Touring vs Sport

The two faces of the RS 2.7

The differences in specification, weight and value are significant.

Touring version (M472)

Numbers: 1,308

  • Target buyer: customers looking for a comfortable sports car they could use every day
  • Weight: around 1,075 kg
  • Specification: the standard 911 S equipment (comfort seats, carpets, a clock, insulation)
  • Glass: standard glazing
  • Market: easier to find, but still extremely expensive

Sport / Lightweight (M471)

Numbers: 200

  • Target buyer: motorsport-minded customers and racing drivers (the basis for the RSR)
  • Weight: around 960 kg, so about 115 kg lighter
  • Lightweight construction: thinner body panels, thin glass (Glaverbel), no insulation
  • Interior: bucket seats, spartan door panels (pull straps), no glovebox, no rear seats
  • Value: a considerably higher collector value because of the extreme rarity

In addition there were 55 cars as the RSR (motorsport) and 17 prototypes. Important: both versions share the same 210 PS engine, and the differences in performance come purely from the weight.

Technical DNA

Specifications and weak points

Click the sections for the detailed analysis.

1. Engine and transmission (2.7 litres / 210 PS) +

Specifications:

  • Type: an air-cooled six-cylinder flat engine (type 911/83)
  • Displacement: 2,687 cc
  • Power: 210 PS at 6,300 rpm
  • Torque: 255 Nm at 5,100 rpm
  • Fuel system: Bosch mechanical fuel injection (MFI)
  • Gearbox: an uprated five-speed type 915
  • Top speed: 245 km/h, 0-100 km/h in 5.8 seconds
Particularities and servicing: the mechanical injection (MFI) is complex, but very reliable when correctly maintained, and it gives an extremely direct throttle response. Setting it up calls for true specialists. The crankcase is magnesium (take care over corrosion and the head studs).
2. Body and exterior: the ducktail +

Features:

  • The ducktail rear spoiler, to reduce lift
  • Flared rear wings (for wider Fuchs wheels)
  • Carrera lettering along the sides
  • A modified front apron (for the oil cooler)

Corrosion and weak points: Corrosion is a serious problem that threatens the structure. The critical areas:

  • Wheel arches and headlight bowls
  • Sills (inside and out) and floor panels
  • The battery box and the area around the window seals
  • Engine mounts and suspension mounting points
A note on the M471: the Sport version used thinner panels, which makes it even more vulnerable to damage and corrosion.
3. Suspension and brakes: motorsport engineering +

The suspension was state of the art for its day and firmer than on the 911 S.

  • Components: Bilstein gas dampers, uprated anti-roll bars, revised geometry
  • Brakes: ventilated discs all round (derived from the 917 race car)
  • Wheels: Fuchs wheels, 6J x 15 (front) and 7J x 15 (rear)
  • Tyres: 185/70 VR 15 (front) / 215/60 VR 15 (rear)
4. Interior: comfort vs purism +

The specification varies enormously by version (M471/M472).

  • Touring (M472): comfort seats, carpets, a clock, a glovebox, occasional rear seats. As in the 911 S
  • Sport (M471): bucket seats (Recaro), felt instead of carpet, pull straps instead of door handles, no glovebox lid, no clock, no rear seats
Condition: the dashboards often crack. Originality is decisive (the right steering wheel, the correct seats). Later additions reduce the value.
5. Beware of replicas and forgeries: the authenticity checklist +

Given the extreme value, there are numerous conversions (clones) built on standard 911s. Here is how to recognise the original:

  • Chassis number (VIN): genuine RS 2.7s have specific number ranges (911360xxxx, for example)
  • Matching numbers: The engine and gearbox numbers MUST agree with the delivery record
  • Body details: the reinforcements at the rear seat wells and on the centre tunnel (for the belt mountings) are RS-specific
  • Panel thickness (M471): on the Sport version, the thin panels must be demonstrable
  • Documents: a certificate of authenticity from Porsche is indispensable
An expert is essential: NEVER buy an RS 2.7 without an appraisal from a recognised RS specialist. The forgeries are extremely good by now.

History: in 2010 good cars still stood at around €200,000. The growth in value has been enormous.

The strengths

  • A blue-chip asset: driving pleasure and value retention in one
  • Small numbers (1,580 cars), an extremely coveted rarity
  • The foundation of every RS model that followed
  • MFI is very reliable when correctly maintained, with a direct throttle response

The risks

  • The risk of forgeries and clones is real
  • Corrosion threatens the structure; the M471 with its thin panels is particularly vulnerable
  • The magnesium crankcase: take care over corrosion and the head studs
  • Original parts (the ducktail, the thin glass) are barely available and expensive
