Cars competed in five classes based on a Capacity / Price index in which the engine capacity in litres was multiplied by the retail price to determine the CP units for each model.[4]
Championship points were awarded on a 9-8-7-6-5-4-3-2-1 basis for the first nine positions in each class plus 4-3-2-1 for the first four positions outright.[1] Only the best placed car from a manufacturer was eligible to score points.[11]
