The 1990 24 Hours of Le Mans was the 58th Grand Prix of Endurance, taking place at the Circuit de la Sarthe, France, on the 16 and 17 June 1990. Once again, the ongoing dispute between the ACO and the FISA governing body meant the race was not part of the World Sports-Prototype Championship. This was the last Le Mans run under the Group C formula, and a number of manufacturers put in a major effort to win, with the notable exception of defending winners Sauber-Mercedes.
The 1989 24 Hours of Le Mans was the 57th Grand Prix of Endurance, taking place at the Circuit de la Sarthe, France, on the 10 and 11 June 1989. This year it was not included as a round of the 1989 World Sports-Prototype Championship. The entry list promised a strong contest between five manufacturers. Jaguar had won in 1988 and went on to win the championship; while Sauber had finished second and was now matching Jaguar on the track. New regulations were coming in 1991, and the first examples of the 3.5-litre normally-aspirated formula were entered by Spice Engineering.
The 1986 24 Hours of Le Mans was the 54th Grand Prix of Endurance as well as the third round of the 1986 World Sports-Prototype Championship. It took place at the Circuit de la Sarthe, France, on 31 May and 1 June 1986. This year saw the return of a full Jaguar works team, to take on the strong Porsche works and customer teams. However, with the fuel regulations relaxed, the turbo-charged cars would be able to use more of their potential power to outrun the normally-aspirated 6-litre Jaguars.
