POINTS SYSTEM for the top 5 (8,6,4,3,2) Fastest Lap: 1 point. Only the best five of seven scores counted towards the world championship. Points for shared fastest laps were divided equally between the drivers. Points for shared drivers were divided equally between the drivers regardless of who had driven more laps unless one of the drivers was deemed to have completed "insufficient distance". Drivers who shared more than one car during a race received points only for their highest finish.
