The 1975 World Sportscar Championship season was the 23rd season of FIAWorld Sportscar Championship motor racing. It featured the 1975 World Championship for Makes which was open to Group 5 Sports Cars and Group 4 Special GT Cars. It also included the FIA Cup for GT Cars and the FIA Cup for 2-Litre Cars. The three titles were contested concurrently over a nine race series which ran from 1 February to 12 July 1975.
† Due to a lack of Group 5 entries, the FIA initially rescinded the championship status of the Daytona race. Several months after the event the FIA retroactively conferred championship status to the race and placed cars into the classes they would theoretically have entered.
Alpine Renault placed third in the championship with the A441 & A442 (pictured).
Points towards the World Championship for Makes were awarded for the top 10 positions in each race in the order of 20-15-12-10-8-6-4-3-2-1. Points were awarded for the position gained by the highest placed car from each make with any positions filled by other cars from the same make not attracting points. No points were awarded for positions gained by cars other than Group 5 Sports Cars and Group 4 Special GT Cars.
Only the 7 best results were retained for championship classification. Discarded points are shown (below) within brackets
