The Porsche 935 is a race car that was developed and manufactured by German automaker Porsche. Introduced in 1976 as the factory racing version of the 911 (930) Turbo and prepared for FIA-Group 5 rules, it was an evolution of the Carrera RSR 2.1 turbo prototype, the second place overall finisher in the 1974 24 Hours of Le Mans.
Zakspeed is a motor racing team from Germany, founded in 1968 by Erich Zakowski and then run by his son Peter Zakowski. It is based in Niederzissen, Rhineland-Palatinate, around 25 kilometres (16 mi) from the Nürburgring circuit.

The Jaguar XJR-9 is a sports-prototype race car built by Jaguar for both FIA Group C and IMSA Camel GTP racing, debuting at the 1988 24 Hours of Daytona.
The 1988 24 Hours of Le Mans was the 56th Grand Prix of Endurance as well as the fifth round of the 1988 World Sports-Prototype Championship. It took place at the Circuit de la Sarthe, France, on the 11 and 12 June 1988. At their third attempt, Jaguar arrived with five cars to take on the strong Porsche works team of three cars, in their only race for the Championship season. The other potential rival was Sauber, now formally backed by Mercedes-Benz, but after a major high-speed tyre-blowout in practice, their two-car team was withdrawn.
The 1984 24 Hours of Le Mans was the 52nd Grand Prix of Endurance, and took place on 16 – 17 June 1984. It was also the third round of the 1984 World Endurance Championship. There were two big stories going into the race weekend: the absence of the Porsche works team and their drivers, and the return of Jaguar. Bob Tullius had commissioned the new Jaguar XJR-5 to run in the IMSA series and entered two for Le Mans. Earlier in the year, FISA had announced abrupt changes to the fuel regulations to bring them more in line with IMSA. Porsche and Lancia objected strongly because of their strong investment in the existing rules. In the absence of dominant Porsche works team, the race was left wide open between Lancia and the number of strong Porsche customer teams.
The 1982 24 Hours of Le Mans was the 50th Grand Prix of Endurance, which took place on 19 and 20 June 1982. It was also the fourth round of the 1982 World Endurance Championship. As well as a significant anniversary, this was a watershed year for Le Mans, with the highly anticipated advent of the FIA's Group C regulations, the essence of which was to allow an open engine formula but a minimum weight for safety and a proscribed fuel allocation.
The 1979 24 Hours of Le Mans was the 47th Grand Prix of Endurance, and took place on 9 and 10 June 1979. With no other major works cars this year, the Porsche team were the strong favourites to win. Their competition would be from Cosworth-powered Mirages and Rondeaus and a swarm of Group 5 and IMSA-class Porsche 935s. The other big talking point was the presence of Hollywood actor Paul Newman, driving for Dick Barbour Racing.
Louis Krages, more commonly known by his pseudonym John Winter, was a German racing driver and businessman.

IMSA GT was a sports car racing series organized by International Motor Sports Association. Races took place primarily in the United States and occasionally in Canada.
The Chevrolet Corvette GTP was an American Grand Touring Prototype-class sports prototype racing car which successfully participated in the IMSA Camel GT from 1984 until 1989. The car was professionally fielded in competition as General Motors' Chevrolet Corvette C4 official factory team effort in the IMSA GTP class.
The Lola T616 is a sports prototype built by Lola Cars to the Group C2 and IMSA GTP regulations. It was built with the intention to compete in the IMSA GT Championship and the World Sportscar Championship, and became the second Mazda-powered prototype to score a class win at the 24 Hours of Le Mans after the 717C triumphed in the same C2 class at the 1983 24 Hours of Le Mans.
The Intrepid RM-1 is a sports prototype racing car designed in 1991 by Bob and Bill Riley and built by Pratt & Miller to IMSA GTP specifications. Powered by a Chevrolet V8 engine, it was campaigned variously by Jim Miller, Prototype Technology Group and Wayne Taylor in the IMSA Camel GT from 1991 through 1993. Though it won only one race in its three seasons of competition, the shovel-nosed Intrepid was notable for the extreme—and at one point, disastrous—levels of downforce it generated, giving it the highest cornering speeds of any prototype of its era. The car's development was set back by a devastating 1991 crash at Watkins Glen that critically injured driver Tommy Kendall, and the program never fully recovered.
The Ford C100 is a sports racing car, initially built and run as a Group 6 car, but later as a Group C car. The C100 was built by Ford in 1981, and initially featured a 4-litre Cosworth DFL V8 engine, which was replaced by a 3.3-litre version of the same engine in 1983, after the car had passed to private hands. Five cars are known to have been built. Although the cars were often very quick in qualifying, reliability problems plagued them, and restricted their successes to two Deutsche Rennsport Meisterschaft victories in 1982, and a single Thundersports victory in 1983.
The Ford Mustang Maxum GTP was an IMSA GTP sports racing car designed by Paul Brown and constructed by Maxum Sports Cars. It was operated by Roush Racing during the 1987 season.
The Ford Mustang GTP was an American race car constructed to compete in the IMSA GTP series by Ford in 1983, based on the "Fox-Body" generation of the Ford Mustang road car. In 1983 the engine was a 1.7 liter twin turbo supplied by Zakspeed. In 1984 it used a destroked 2.1-litre 16 valve turbocharged variant of the 2.3 litre Ford Lima engine, capable of producing around 600 hp. The 2.1 litre engine is often misidentified as more common 2.1 litre variant of the BDA. Contrary to convention for an IMSA GTP car, the engine was fitted in the front of the car. Zakspeed would replace the car with the Ford Mustang Probe for 1985, while Roush Performance would build the no more successful V8-powered Ford Mustang Maxum GTP in 1987.
The Alba AR6 was a Group C2 sports car prototype, designed, developed and built by Italian manufacturer Alba Engineering in 1985, to compete in the World Sportscar Championship, and used in sports car racing until 1990. A variant of the car, called the Alba AR8, was used in the IMSA GTP Championship.
The Ford Mustang GTX was an American GT race car constructed to compete in the GTX category of the IMSA GT Championship series by Ford. Originally based on the second generation Ford Mustang, and later the third generation Ford Mustang road car, built between 1979 and 1983. It was initially powered a 1.7-liter twin-turbo four-cylinder engine, supplied by Zakspeed, and producing around 600 hp (450 kW). This was later changed in 1982, to an enlarged 2.1-liter turbocharged variant of the Ford-Cosworth BDA straight-four engine, capable of producing around 675 hp. The car was very light, weighing only around 1,760 lb (800 kg).
Grand Touring Experimental (GTX) is a former classification and set of regulations designated to grand touring cars and sports prototypes in sports car racing competing in the IMSA GT Championship, maintained by IMSA between 1977 and 1982. Some cars were based on FIA Group 5 rules; such as the Porsche 935, and some cars were based on FIA Group 6 regulations, such as the Lola T600. Like the original GTO class, the class rules specified turbocharging and supercharging was allowed on engines up to a size of 6.0 L (370 cu in); with engine design and number of cylinders being free and unrestricted. Engines over 6.0 L (370 cu in) were required to be naturally-aspirated.
