NASCAR Xfinity Series today: Calendar 2026

Get reminders for new NASCAR Xfinity Series events

The NASCAR Xfinity Series is a professional stock car racing series in the United States governed by NASCAR. It serves as the second national competition tier, functioning as a stepping stone for drivers aspiring to NASCAR's top-tier Cup Series. Race cars are modified vehicles powered by 358-cubic-inch V8 engines producing approximately 650 horsepower, with four-speed transmissions and a weight of around 3,400 pounds. The series competes on the same tracks as the Cup Series: oval speedways of varying sizes, superspeedways, and road courses throughout the United States. A typical race weekend consists of practice and qualifying sessions on Friday and the main race on Saturday. The series operates a modern playoff system with twelve qualified drivers competing in a three-round elimination format. A distinctive feature is the participation of Cup Series drivers during their off-weeks, who use these races for additional track time and practice. The next round is Martinsville on Saturday, 31 October 2026 at Martinsville Speedway.
