NASCAR Xfinity Series Cars (B Class)

NASCAR Xfinity Series cars in iRacing represent NASCAR’s second-tier series, the developmental ladder below the Cup Series. Known at various points as the Busch Series and Nationwide Series, the Xfinity Series fields smaller-displacement cars than the Cup Series on a similar oval-heavy schedule. In iRacing, these cars are classified as B Class and serve as a step up from slower oval machinery before moving into Cup-level cars.
