ChampCar Endurance Series: D

The ChampCar Endurance Series is a multi-class amateur endurance racing series using budget production-based cars, with drivers sharing cockpits across distances. The field is competitive amateur in calibre, led by drivers including Ben Keating and Chandler Smith. The six classes range from competitive amateur to developing level, with class strength fairly consistent across the grid. The series draws drivers primarily from NASA and the SCCA regional and national structure, as well as from American Endurance Racing; its standing sits between the regional SCCA clubs and the stronger SCCA Majors, while matching amateur grids from PCA and NASA. The series functions as a natural waypoint within the amateur endurance ecosystem rather than serving primarily as a stepping stone upward to professional ranks.
