Why it matters

Porsche planned 500 cars for homologation, sold them all within weeks of the Paris Motor Show in October 1972, and went on to build 1,580. The Carrera RS was the first series-production car with a rear spoiler, which Porsche says started a trend.

Production

Every figure says what it counts.

Why more than one figure?

RM Sotheby’s gives 1,525; Porsche gives 1,580 including the 55 racing RSR cars and 17 base vehicles. The difference is probably what is counted.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Around 15 engineers developed the car from May 1972. It was presented at the Paris Motor Show on 5 October 1972 at DM 34,000, and all 500 planned cars were sold by the end of November. After the 1,000th car it was homologated for Group 3. The body was widened by 42 mm at the rear; the ducktail spoiler raised the top speed by 4.5 km/h. 29 paint colours were offered and 27 were actually used.

How it differs from the standard 911 Carrera RS 2.7

Only 200 of the 1,580 Carrera RS 2.7 were built with the M471 Sport package – the “Lightweight”, 115 kg lighter than the Touring at 960 kg.

The M471 Sport package stripped the Carrera RS 2.7 to a factory kerb weight of 960 kg; about 200 of the 1,580 cars were built this way.

Identifying a genuine Porsche 911 Carrera RS 2.7 Lightweight (M471)

A genuine Lightweight is an RS 2.7 ordered with option M471, so factory records showing M471 and matching engine and gearbox numbers are the key evidence; auction examples carry chassis numbers in the 91136 series (e.g. 9113600476, 9113601399). Construction details described for M471 cars include 0.70 mm body-skin steel instead of the usual 1.00–1.25 mm, thinner laminated Glaverbel glass including the windscreen, a fibreglass engine lid held by rubber clamps, fibreglass bumpers, and a bonnet crest initially glued on or replaced by a decal. Inside: rubber mats instead of carpet, no rear seats, no clock or passenger sun visor, no glovebox lid, flat door panels with pull-cord releases, and thinly padded bucket seats (lightweight seat shells were available on request).
