1980 World Sportscar Championship season

The 1980 World Sportscar Championship season was the 28th season of FIA World Sportscar Championship motor racing. It featured the 1980 World Championship for Makes which was contested as a series running under both Fédération Internationale de l'Automobile (FIA) and International Motor Sports Association (IMSA) regulations. It ran from February 2, 1980 to September 28, 1980, and comprised 11 races, including races run with Camel GT Championship.

A World Challenge for Endurance Drivers was also held over an eleven round series, six of which were run concurrently with rounds of the World Championship for Makes. The Challenge was not awarded World Championship status, but would be promoted the following season and join the Championship for Makes. John Paul, Sr. won the World Challenge.

Points were awarded for 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 for 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.
