The Tire Rack SCCA ProSolo Series is an adrenaline-pumping autocross format where solo isn’t solo. Drivers still run a course by themselves, but start off side-by-side drag racing style and attack mirror-image courses to see who gets back to their respective finish lines together.

After class competition, it’s time for single-elimination challenge rounds. The first is a bragging-rights Bonus Challenge drawn at random, a Ladies Challenge for the top-performing ladies class drivers, and the big one – the Super Challenge, which pits the top 32 drivers from regular competition into a solo bracket madness where coming out on top is simple: string together 12 winning runs in a row while avoiding red-lighting, hitting cones and glory-robbing mistakes.
