Footnotes

Porsche revived the Carrera name for its luxuriously equipped, top-of-the-range 911 in 1973. Designated 'Carrera RS' (RennSport), the newcomer was intended as a limited-edition product for Group 4 GT racing, a class that required a minimum of 500 built. However, the resulting demand for this fabulous car proved so great that the production run was later progressively extended, ending up at 1,590 units. Based on a lightened 911S platform, the Carrera RS featured revised suspension and wider rear wheels (beneath flared 'arches) for improved handling, while the 2.7-litre, fuel-injected, air-cooled six-cylinder engine's 210bhp boosted top speed to around 150mph. Not merely a styling gimmick, the Carrera's trademark 'duck's tail' spoiler made a vital contribution to high-speed stability, a virtue of increasing importance as power outputs continued to rise.

Based on the lightweight 911 Carrera RS announced the previous year, Porsche's RSR GT-category racer collected overall wins in the World Sportscar Championship at Daytona and the Targa Florio in 1973, defeating 3-litre prototypes from Ferrari, Matra and Mirage-Ford in the process, an outstanding achievement for a production-based car.

Rare and highly sought after, original RS and RSR models cost a small fortune, a state of affairs that has inspired many a Porsche enthusiast to create replicas of what was one of the defining sports cars of its era.

A 1977 model (3.0-litre SC) first registered on 8th October 1976, this 911 was comprehensively rebuilt and upgraded to 1974 RSR specification in 2011. From 2012 to 2014, this car competed in the Belgian Historic Cup and in 2014 won the Belgian Championship. Since 2015 the Porsche has formed part of a private collection.

The RSR conversion involved fitting a 3.0-litre engine, built around a Type 930/10 crankcase, which features Bosch slide-valve induction and produces 325bhp. Other noteworthy features include a Type 915 five-speed gearbox; Porsche 917-type Turbo brakes; Bilstein suspension; and glassfibre RSR-style additions to the original bodywork, German Fahrzeugbrief and Royal Automobile Club de Belgique Passeport Technique d'Épreuve.

Porsche ressuscita le nom de Carrera pour son haut de gamme 911, en 1973. Baptisée Carrera RS (RennSport), la nouvelle venue devait en principe être une série limitée pour l'homologation et permettre à l'usine de l'engager en Groupe 4 dans la classe GT spéciale, après un minimum de 500 exemplaires construits. Mais la demande pour cette fabuleuse voiture fut si importante que la production fut prolongée progressivement pour finir avec 1 590 unités Construite sur une plate-forme allégée de 911 S, la Carrera RS faisait appel à une suspension modifiée et des roues arrière plus larges (sous des passages de roues gonflés) pour améliorer la tenue de route, tandis que le moteur six cylindres 2,7 litres à injection refroidi par air de 210 ch portait la vitesse de pointe aux environs de 240 km/h. Son aileron « queue de canard » n'était pas seulement là pour faire joli, mais étaient indispensables pour sa stabilité à haute vitesse, un détail qui prenait de plus en plus d'importance avec l'accroissement de la puissance.

Prenant pour base la 911 Carrera RS présentée l'année précédente, la Porsche RSR de compétition pour la catégorie GT remporta des victoires dans le championnat du monde à Daytona et à la Targa Florio en 1973, battant des prototypes 3 litres Ferrari, Matra et Mirage-Ford, un exploit extraordinaire pour une voiture issue de la série.

Rare et très recherchée, les modèles RS et RSR originaux coûtent une petite fortune, un état de fait qui a poussé de nombreux passionnés de Porsche à créer des répliques de ce qui était la sportive ultime de son époque.

Cette 911, un modèle SC 3 litres de 1977 a été immatriculée le 8 octobre 1976 et a été entièrement reconstruite et préparée aux spécifications d'une RSR de 1974 en 2011. De 2012 à 2014, la voiture a participé à la Coupe historique de Belgique et a remporté le championnat de Belgique en 2014. Depuis 2015, la Porsche faisait partie d'une collection privée.

La conversion en RSR a consisté à monter un moteur 3 litres construit autour d'un vilebrequin type 930/10 avec soupapes Bosch développant 325 ch. Les autres caractéristiques remarquables sont la boîte à cinq rapports type 915, les freins type Porsche 917, la suspension Bilstein et les éléments de carrosserie en fibre de verre style RSR, un Fahrzeugbrief allemand et le passeport technique d'épreuve de l'Automobile Club Royal de Belgique.
