In 1982 the FIA ​​introduced a new rules called "Group C" for the World Sports Prototype Championship to replace the now obsolete Groups 5 and 6. The new regulation foresaw restrictions on fuel consumption, and on size and weight of the cars, while the engines displacement and the number of cars to be built to obtain the homologation were free. Two classes of prototypes were created: Class C and Class C Junior, which later became C1 and C2. The first class was dedicated to the great builders while the second was designed for private teams and small builders. To compete in the World Championships in the Group C Sports Prototype, Porsche built the 956. The car designed by the team of Norbert Singer, was assembled around the first aluminium monocoque made by Porsche for a race car, replacing the classic tubes frame used until then. The engine was the classic 6-cylinder boxer of 2649 cc supercharged with two KKK turbochargers capable, in the race set-up to develop 630 hp, with water cooling for cylinder heads and air for cylinders and crankcase. In 1983 the 956 was also made available to customers and in 1984 the version 956 B was introduced that through a different electronic control unit could develop up to 640 hp. The aerodynamics were very accurate, the car was equipped with Venturi tunnels for the ground effect and an effective extractor. There were 2 different configurations that provided a rear wing arranged in a standard position and a rear wing in a lowered position for fast circuits. To change from one configuration to another, it was sufficient to replace the bonnet.

 Nel 1982 la FIA istituì un nuovo regolamento denominato “Gruppo C” per il Campionato Mondiale Sport Prototipi per sostituire gli ormai obsoleti Gruppi 5 e 6. Il nuovo regolamento prevedeva limitazioni relativamente al consumo di carburante, alle dimensioni e al peso delle vetture mentre la cilindrata dei motori e il numero di vetture da costruire per ottenere l’omologazione erano liberi. Furono create due classi di prototipi: La classe C e la classe C Junior, diventate poi C1 e C2. La prima era dedicata ai grandi costruttori mentre la seconda era stata concepita per le squadre private e i piccoli costruttori. Per competere nel Campionato Mondiale Sport Prototipi nel Gruppo C, la Porsche costruì la 956. La vettura progettata dalla squadra di Norbert Singer, era assemblata intorno alla prima monoscocca in alluminio realizzata dalla Porsche per un’auto da corsa, in sostituzione del classico telaio in tubi utilizzato fino ad allora. Il motore era il classico 6 cilindri boxer di 2649 cc sovralimentato con due turbocompressori KKK capace, in assetto gara di sviluppare 630 CV, con il raffreddamento ad acqua per le testate e ad aria per i cilindri e il basamento. Nel 1983 la 956 fu resa disponibile anche ai clienti e nel 1984 fu introdotta la versione 956 B che tramite una differente taratura della centralina elettronica poteva sviluppare fino s 640 CV. L’aerodinamica era molto curata, la vettura era dotata di tunnel Venturi per l’effetto suolo e di un estrattore efficace. Le configurazioni erano 2 e prevedevano una l’alettone posteriore sistemato in posizione standard e una l’alettone sistemato più in basso e di corda ridotta, per i circuiti veloci. Per passare da una configurazione all’altra era sufficiente la sostituzione del cofano motore.

The debut took place with a single car at the Silverstone 1000 Km in 1982 in the hands of Jacky Ickx and Derek Bell where they finished second. Silverstone was the second race of the World Championship (the first was the Monza 1000 Km). The second race was the 24 Hours of Le Mans where the three official Porsche 956 ended first with Jacky Ickx and Derek Bell, second with Jochen Mass and Vern Schuppan and third with Hurley Haywood, Al Holbert and Jürgen Barth. The Porsche 956, conquered the 24 Hours of Le Mans also in 1983, 1984 and 1985 and won the Sports Prototypes World Championships in 1982, 1983, and 1984. In 1985 it was introduced in Europe (in the United States it was in 1984) the Porsche 962.

Il debutto avvenne alla 1000 Km di Silverstone nel 1982 con un solo esemplare nelle mani di Jacky Ickx e Derek Bell, la seconda gara del Mondiale Marche (la prima fu la 1000 Km di Monza, link) dove finirono al secondo posto. La seconda gara alla quale partecipò fu la 24 ore di Le Mans dove le tre Porsche 956 ufficiali finirono prima con Jacky Ickx e Derek Bell, seconda con Jochen Mass e Vern Schuppan e terza con Hurley Haywood, Al Holbert e Jürgen Barth. La Porsche 956, conquisto la 24 Ore di Le Mans anche nel 1983, 1984 e 1985 e vinse il Campionato mondiale sport prototipi nel 1982, 1983, e 1984. Nel 1985 venne introdotta in Europa (negli Stati Uniti lo fu nel 1984) la Porsche 962.

The car in the photos is the 956B-118. The chassis 118 was the last in the 956 series to have been sold to customers. It was produced in 1984 and delivered to Nova Engineering in Japan to replace the frame 108 which was destroyed in a fire during the Fuji 500 km on 3 June 1984. The Porsche 956B-118 was used exclusively in Japan by the Team Trust and driven by the Australian Vern Schuppan, from Japanese Yoshimi Katayama and Keiichi Suzuki and by Hans-Joachim Stuck. During the 500 km of the Fuji of 1985 the car was damaged again by a fire which ended the sports career.

Nice book, full of very useful information for those who want to deepen their knowledge on the technical and historical aspects related to this type of cars. The themes of aerodynamics and its development over the years until the advent of the ground effect, the construction techniques of the frames, including those in composite materials, suspensions, brakes and transmissions, are explained in great detail. The part relating to the engines is also very interesting. The text is written in English, is very fluent and is accompanied by several photographs, all in black and white. It is definitely recommended for all fans, especially those of historic cars.

Bel libro, ricco di informazioni molto utili per che vuole approfondire la conoscenza sugli aspetti tecnici e storici legati a questo tipo di vetture. I temi dell’aerodinamica e il suo sviluppo negli anni fino all’avvento dell’effetto suolo, le tecniche di costruzione dei telai, compresi quelli in materiali compositi, di sospensioni, freni e trasmissioni, sono spiegati in modo molto dettagliato. Molto interessante anche la parte relativa ai propulsori. Il testo è scritto in inglese, è molto scorrevole ed è corredato da parecchie fotografie, tutte in bianco e nero. E’ un libro sicuramente consigliato a tutti gli appassionati, in particolare di auto storiche.
