Under article 6.2 of the FIA sporting regulations, "The title of Formula One World Champion Constructor will be awarded to the competitor which has scored the highest number of points"] From the inaugural season of the World Constructors' Championship in 1958 up until the 1978 season only the highest-scoring driver in each race for each constructor contributed points towards the World Constructors' Championship (then officially as the International Cup for Formula One Constructors); since the 1979 season points from all cars entered by each constructor have counted towards their championship total.
