1983 Porsche 956 Group C

Chassis #956-101

We are thrilled to offer for sale another significantly historic and important Porsche - the first ever customer-delivered Porsche 956 Group C racing car. The 1983 Kremer Racing, Kenwood sponsored Porsche 956 driven by Mario Andretti, Michael Andretti and Philippe Alliot to 3rd overall at Le Mans in 1983.

Group C - Porsche
Regarded by many as a modern 'golden age' of sports car racing, the FIA's new Group C category for prototypes lasted from 1982 to 1993. It was designed to replace both Group 5 (closed touring prototypes like the 935) and Group 6 (open sports car prototypes like the 936). As interest in Group C grew, the world's major motor manufacturers joined the fray with Porsche, Jaguar, Ford, Aston Martin, Lancia, Mercedes-Benz, Mazda, Nissan and Toyota all fielding works entries and attracting major sponsorship from big brand companies whose liveries became famous on these highly effective and attractive racing cars.

Rather than being based predominantly on engine capacity and weight, the traditional parameters of motor racing formulae, Group C placed a limit on the amount of fuel permitted but otherwise allowed constructors a virtually free hand in design. Porsche responded immediately to the challenge and in just nine months, Norbert Singer oversaw an engineering team at the Porsche motorsport department in Weissach, to design, construct and develop the Porsche 956.

The 956 was the first Porsche ever to utilize an aluminium, monocoque chassis, which increased rigidity over the traditional tubular space-frame construction and in conjunction with state-of-the-art chassis tunnels and a wind-tunnel tested and developed, closed-cockpit bodywork design, created a ground-effect racing car able to produce significant down force at high speeds.

Power for the 956 was derived from a version of the tried-and-tested Porsche, twin-turbocharged flat-six engine which had previously powered the 1981 Le Mans-winning Porsche 936. Designated the Type 935/76, it had water-cooled cylinder heads and air-cooled cylinders. Air fed into a Naca duct in the roof, which channeled down to the engine and then emerged from under the car through openings in the lower bodywork, which slightly upset the ground-effect. The exhaust exits were located on either side of the bodywork, just in front or the rear wheels in order not to upset the air flow any further. The 2,650cc KKK-turbocharged unit was estimated to develop 630bhp at 8,200rpm and have a top speed of circa 240mph.

In total, Porsche built just 11 examples of the customer 956, which were sold as turn-key racing cars and were fully-supported by the factory. Porschesport Customer Racing Services AvD undertook engine preparation and a comprehensive 956 parts catalogue was produced and a large parts-service truck was taken to each Group C race, providing everything needed for running a 956 chassis.

Chassis 956-101
Manufactured by Porsche and supplied new to Kremer Racing, who took delivery in April 1983. The car was presented to the press on 27th April at Hockenheim in the presence of Mario and Michael Andretti.

1983 Le Mans 24 Hours
Mario and Michael Andretti teamed up with Philippe Alliot at the Sarthe. On Wednesday Mario set the quickest time of the private Porsche 956s in 3m 28.36s. In the Thursday session, two other privateers (956-106 and 956-114) went quicker. Mario started from 8th on the grid and immediately pulled back two places after Lammers (956-106) and Ickx (956-005) collided. He finished the first hour in fourth place and then a puncture sent the Blue Porsche tumbling down the time sheets. No. 21 began the great fight back and moved up from 15th at 18.00h to third by 01.00h on Sunday morning. Apart from an Alliot spin at 02.07h and another by Mario at 03.21h, the trio had a quiet night. At 08.00h, Bell hit an ignition problem and no. 21 moved into second place where it stayed until 10.30h when it was re-passed by the works Porsche. In the closing stages of the race the two Joest Porsches began to catch 956-101, which held onto third until the flag.

This extremely significant Porsche went onto race for four seasons in the hands of no fewer than twelve different Formula One drivers, including three World Champions (see tables below):

Ownership Provenance
1983: Supplied new by Porsche to Porsche-Kremer-Racing (Köln, Germany) -
1985: Sold to Yojiro Yoneyama (Nova Engineering) (Japan) -
1987: Sold by Nova to Vern Schuppan
1995: Sold by Schuppan to current owner (UK) -
2018: For sale via Maxted-Page Ltd (UK)

Chassis 956-101 both has an impressive race history, together with a documented and continuous ownership history from new.

Having raced for two years at the pinnacle of sports car racing throughout the 1983 and 1984 World Endurance Championship season - its highlight sharing the podium in 3rd place at Le Mans in 1983 alongside the winning works Rothmans Porsche 956-003 of Hurley Haywood, Al Holbert and Vern Schuppan and second place works Rothmans Porsche 956-005 of Jacky Ickx and Derek Bell.

The car was sold by Kremer after the 1984 season to Nova Engineering in Japan and was then run by them for Jiro Yoneyama to drive in the All Japan Sports Car Championship during 1985 and 1986.

By this point, FIA regulations for the World Endurance Championship and IMSA in the USA, had already forced a re-design of the 956 chassis to provide greater leg protection from frontal impact. In response to this, Porsche designed the 962 chassis and in support of teams running 956s, Porsche offered the new 962 chassis on a part-exchange basis. Nova then received a number of new 962 chassis, but due to the outstanding history of 956-101 and the fact that it had been associated with Vern Schuppan in its first race, NOVA agreed to sell 956-101 directly to Schuppan, who was at this time also driving for them in Japan in their TRUST sponsored car.

Schuppan, recognised the both the significance and the increasing rarity of 956s and was able to purchase the car to put in storage for himself. In 1995-1997 he commissioned its restoration by ADA Racing with an engine rebuild by G-Force and eventually sold the car to its current owner, mid-way through this work being carried out by ADA.

Once again 956-101 was kept in storage, unused and undamaged by the current owner, until 2013 when it was then comprehensively re-commissioned by ex-ADA engineer, Trevor Crisp (Katana Limited) and afterwards demonstrated by Mike Wilds at the 2014 Goodwood Members Meeting.

Offered today, still immaculately presented in its 1983 long tail configuration and Kenwood livery and fitted with a 2.6 litre / type 935/76 engine with minimal running time since rebuild.

This immensely rare and important Le Mans podium Porsche 956, is now available for purchase for the first time in over 25 years. The car is naturally eligible for the Peter Auto-Group C Racing series and Le Mans Classic Group C grid, making this a most exciting time for the serious collector and / or historic racer to acquire one of the finest examples of this user-friendly yet most successful ever, sports-racing Porsche in history.
