The World Championship for Makes was only open to select categories of cars. This included the FIA's
Group 5 Special Production Cars,
Group 4 Grand Touring Cars,
Group 3 Series Production Grand Touring Cars,
Group 2 Touring Cars, and
Group 1 Series Production Touring Cars. An overall championship was awarded as well as two class titles: Division 1, for cars over 2000 cc and Division 2 for those under 2000 cc. Points were awarded to the top ten finishers in each division in the order of 20-15-12-10-8-6-4-3-2-1, with only the best eight results out of the eleven races being counted. Only the best placed entry of each make in each division was eligible to score points, with no points awarded to other placings.
Overall Championship The overall championship was to be awarded to the make achieving the highest net point score in either Division. The resultant tie between Porsche and Lancia was decided in Lancia's favour due to the greater number of Division victories scored by the Italian make.
