The Performance Factor is a method of classifying the wide variety of cars used in single competitions.
Five factors are used to calculate the Performance Factor number:
Racing Weight, Engine, Aerodynamic, Drive Train and Chassis
Competitors input the values relating to each factor to create a Performance Factor number for their car. This number is used to classify the cars into a group within their category.
In Hill Climbing there are two categories:
- C1 for production type cars using Technical Regulation article 258-1 of Appendix J.
- C2 for Prototypes using Technical Regulation article 258-2 of Appendix J.
In the 2025 European Championship the groups are divided as follows:
