Lot 136: 1982 Porsche-Kremer CK5 - ex Le Mans, Eligible for Historic Group C

The Excellence of Porsche, Coys (9 September 2007)

1982 Kremer-Porsche CK5 Group CRegistration Number: N/A Chassis Number: CK5-01The name Kremer is synonymous with Porsche in motor sport, in particular in endurance events such as the Le Mans 24 Hours, and during the 1970s and '80s the Cologne-based race specialist's modified 911, 934, 935 and 936 models enjoyed much success. With the advent of the fuel formula-regulated World Endurance Championship in 1982 for Group C cars, however, the Kremer brothers Erwin and Manfred had to build a one-off machine to bridge the gap until Porsche made its latest 956 model available to privateer teams. At the new Kremer CK5's heart was a Porsche 908/936-based alloy, spaceframe chassis and an air-cooled 2,827cc, mechanically fuel-injected 935, single camshaft, two valve per cylinder, flat six engine with twin turbochargers. This was mated to a four speed 917 transaxle, while the rear suspension also came from the 917 and at the front from the 935, with the whole clothed in aggressively styled, two-seater, fibreglass coupé coachwork. The CK5 made its WEC race debut in the Le Mans 24 Hours, driven by Danny Ongais, Ted Field and Dale Whittington and impressively climbed as high as third position during the race after qualifying ninth on the grid - including a 207mph maximum on the Mulsanne Straight. At the Spa Francorchamps 1,000km the CK5, this time piloted by Rolf Stommelen and Stefan Bellof, retired with starter motor problems, but again after a strong showing that saw it running third behind the works Porsche 956s, the only cars, together with the Lancia-Martin LC1, to better the Kremer on pace in qualifying. A WEC result came at the Brands Hatch 1,000km, chassis CK5-01, driven by Frank Jelinski and John Paul Jnr, coming home in sixth place. Further noteworthy success came during the 1982 season where the CK5 had proved to be a front runner in the German Racing Championship for Group 5 machines: at the Norisring Stommelen finished fifth, on the Hockenheim Grand Prix circuit he took pole position and again finished fifth, on the short circuit at the same track he won having qualified second, and at the Nurburgring Super Sprint he took third place and set the fastest lap. In 1983 Kremer-Porsche CK5-01 was sold early in the year to Porsche privateer Richard Cleare; the chassis was now fitted with a 2,992cc engine. Partnered by Tony Dron and Margie Smith-Hass, the car first performed at the Monza 1,000km that year, the opening round of the WEC. Another impressive sixth place for the car followed at the Silverstone 6 Hours and, notably, Cleare and Dron finished behind five 956s, the one immediately in front, incidentally, being Kremer's recently acquired example. The Le Mans 24 Hours came next, and having qualified 24th and run as high as 10th in the first hour, the CK5-01 recorded the 11th fastest speed down Mulsanne of 221mph, driven by Cleare, Dron and Richard Jones. Improvements were made to CK5-01 for 1984, including fitment of a Hewland VG five speed transaxle with revised rear suspension, ground-effect tunnels beneath the chassis and revised bodywork. Running a three litre engine again, Cleare, this time partnered by John Cooper and David Leslie, competed in the Brands Hatch 1,000km, the only WEC round entered that year. The 1985 season saw the 16in rear wheels replaced by 19in items and fitment of an adjustable front wing, and the car was again raced at Brands Hatch, Dron this time partnering David Leslie. By 1986 the CK5 had passed into the ownership of Christopher Stewart who used it on test days at Silverstone; it also took part in a Jaguar Drivers Club race in which Nick Faure took second place. Finished in white and bearing its 'les must de Cartier' period livery, chassis CK5-01 formed part of the famous Albert Obrist collection in Switzerland, before it was bought by well known French amateur racer Hervé Fontaine who passed it on to its current Monaco-based owner of some 10 years. Circuit use has been limited to track days at Paul Ricard and the car has been maintained in running order throughout this time, including a recent rebuild of the turbochargers. As the first ever Kremer-Porsche sports-prototype Group C machine it is unique, and its sale represents an opportunity to acquire a very individual race car that is ideally suited for, and would no doubt be very competitive in, the increasingly popular and spectacular historic Group C/GTP Racing series - and for considerably less money than a Porsche 956 which, in the right hands, it is capable of beating. Chassis CK5-01 comes with a copy of the original period German Automobile Club identification papers, copies of various magazine race reports featuring the car, assorted bills, technical information, correspondence from Kremer confirming its provenance and other documentation. A highly desirable and effective racing car.Estimate £110,000 - £140,000
