Points were awarded to the top 10 finishers in each division on a 20-15-12-10-8-6-4-3-2-1 basis. Manufacturers were only allocated points for their highest finishing car with no points awarded for positions filled by any other car from that manufacturer.
Only the best six points finishes could be retained towards the championship, with any other points earned not included in the total.
The overall championship was awarded to the winner of Division 2 (Over 2000cc), Porsche thus scoring their third straight World Championship for Makes victory.
