Class structure
Points system
Championship points were awarded on a 9-6-4-3-2-1 basis for the first six placings in each class at each round.[1] Bonus points were awarded on a 4-3-2-1 basis for the top four placings irrespective of class at each round.[1]
Where rounds were run in multiple parts, drivers were allocated points on a 20-16-13-11-10-9-8-7-6-5-4-3-2-1 basis for the first fourteen positions in each part.[1] These points were then aggregated to determine the placings for that round.[1]
