TRSCCA Autocross
Autocross, also known as SCCA Solo, is a competitive driving program that challenges drivers to navigate a course marked out by traffic cones in the fastest time possible. The events are designed to be accessible to drivers of all skill levels, with classes based on modifications and experience. Participants are timed on a course, with the fastest time in each class declared the winner. Autocross emphasizes skill and precision over outright speed, making it fun and challenging for enthusiasts of all levels.
2024 Season
Class Championships

Competitors who complete a full season within the same competition class will be eligible for the TRSCCA's year end championship.

  • Competitors must be a registered member of the Tennessee Region SCCA
  • Novice class competitors may compete in the Novice group for up to one (1) full calendar year, or three (3) class wins, whichever comes first. Then they will be asked to graduate into the normal class for their vehicle. Novices (and new, non-novice class competitors) may be selected for the annual 'Rookie of the Year' award.
  • A minimum of 6 events within a class are required to qualify for the end of season awards. Any events in excess of this minimum will count towards the top scores. (i.e. if you compete in 10 events, the worst 4 will be dropped)

Your Vehicle

Classing: Cars are classed by both their modifications and general potential. The SCCA has a brief "Introduction to Autocross Classes" that can help familiarize you with the basics, and the SCCA Solo Rule Book has specific class rules in Section 13 thru 20 and a comprehensive list of vehicles/classes in Appendix A.
