Before the debut of the 2025 NASCAR season, some updates have been made to the ELO ratings of the NASCAR DRIVERS UNIVERSE. The CIELO Ratings for the NASCAR Cup, Xfinity, and Truck Series have been tabulated with revision 3.2.0. The formulaic changes from the previous revision, 3.0.6, increased the data set to include the 2015 season forward and decreased the k-factor from 12 to 10. The most notable resulting change to the Top 10 lists is the inclusion of Jeff Gordon for the Cup Series ratings.
An additional change is the time window for reporting ratings for (in)active driver lists. The active lists now only include drivers who have competed once in the current or previous season.
