A new championship was introduced in 1972, ending the distinction between Group 4 and 6 cars, and was called the World Championship for Makes for Prototype Sports Cars (Group 5) and GT Cars (Group 4). From 1976, only Group 5 cars were allowed to race, and in 1981 a drivers championship was introduced for the first time. The championship was renamed again in 1986, becoming The Sports-Prototype World Championship.
The following results are in chronological order, and cover both the makes and drivers championships. The results are available for:-
