The World Championship of Makes was contested in two classes, under and over 2000 cc of engine capacity. At the end of the championship Lancia and Porsche had won the two classes respectively with the same pointscore. The tie was broken in favour of Lancia, a fitting reward for the Italian manufacturer who had fielded a factory team of two or three Lancia Montecarlos across the European races featuring Formula One drivers and World Rally Champions like Riccardo Patrese, Eddie Cheever, Michele Alboreto, Piercarlo Ghinzani, Walter Röhrl and Markku Alén, as well as providing support to the Jolly Club team's Montecarlo who made trips to North America when the factory team did not.
