Series Overview

The NASCAR Xfinity Series is the second tier of NASCAR's national series ladder, serving as the primary proving ground for drivers aspiring to reach the Cup Series. Founded in 1982 as the NASCAR Busch Series, it has carried several title sponsor names over the decades — most recently rebranded as the O'Reilly Auto Parts Series for 2026.

The series runs a 33-race schedule that closely mirrors the Cup Series calendar, often racing on the same weekend at the same tracks. This gives fans double the action and drivers a chance to log extra laps at venues they'll compete on in NASCAR's premier series.

The Xfinity Series has launched the careers of some of NASCAR's biggest names — Dale Earnhardt Jr., Kevin Harvick, Carl Edwards, and more recently Chase Elliott and Christopher Bell all cut their teeth here before moving up to Cup competition.
